1.2 创建相关的包

  • dao
  • domain
  • controller
  • service Alt Text

    1.3 创建类（此处以账户为例）

    1.3.1 xyz.slienceme.domain.Account;

    ```java package xyz.slienceme.domain; import java.io.Serializable;

/**

  • @Author slience_me
  • @Time : 2021/7/4 8:58
  • 账户 */ public class Account implements Serializable { private Integer id; private String name; private Double money; //生成对应的setter&getter方法，toString方法，此处节省空间删除了 } ```

    1.3.2 xyz.slienceme.dao.AccountDao;

    ```java package xyz.slienceme.dao; import xyz.slienceme.domain.Account; import java.util.List;

/**

  • @Author slience_me
  • @Time : 2021/7/4 9:02

  • 账户dao接口 */ public interface AccountDao {

    /**

    • 查询所有账户信息
    • @return */ public List findAll();

    /**

    • 保存账户信息
    • @param account */ public void saveAccount(Account account); }
#### 1.3.3 xyz.slienceme.service.AccountService;

```java
package xyz.slienceme.service;
import xyz.slienceme.domain.Account;
import java.util.List;

/**
 * @Author slience_me
 * @Time : 2021/7/4  9:04
 */
public interface AccountService {

    /**
     * 查询所有账户信息
     * @return
     */
    public List<Account> findAll();

    /**
     * 保存账户信息
     * @param account
     */
    public void saveAccount(Account account);
}

1.3.4 xyz.slienceme.service.impl.AccountServiceImpl;

package xyz.slienceme.service.impl;
import xyz.slienceme.domain.Account;
import xyz.slienceme.service.AccountService;

import java.util.List;

/**
 * @Author slience_me
 * @Time : 2021/7/4  9:04
 */
public class AccountServiceImpl implements AccountService {

    @Override
    public List<Account> findAll() {
        System.out.println("业务层:查询所有账户信息。。。");
        return null;
    }

    @Override
    public void saveAccount(Account account) {
        System.out.println("业务层:保存账户信息。。。");
    }
}

1.3.5 在resources中创建applicationContext.xml

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xmlns:context="http://www.springframework.org/schema/context"
       xmlns:aop="http://www.springframework.org/schema/aop"
       xmlns:tx="http://www.springframework.org/schema/tx"
       xsi:schemaLocation="http://www.springframework.org/schema/beans
    http://www.springframework.org/schema/beans/spring-beans.xsd
    http://www.springframework.org/schema/context
    http://www.springframework.org/schema/context/spring-context.xsd
    http://www.springframework.org/schema/aop
    http://www.springframework.org/schema/aop/spring-aop.xsd
    http://www.springframework.org/schema/tx
    http://www.springframework.org/schema/tx/spring-tx.xsd">
    
    <!-- 开启注解扫描，要扫描的是service和dao层的注解，要忽略web层注解，因为web层让SpringMVC框架去管理 -->
    <context:component-scan base-package="xyz.slienceme">
        <!-- 配置要忽略的注解 -->
        <context:exclude-filter type="annotation" expression="org.springframework.stereotype.Controller"/>
    </context:component-scan>
</beans>

1.3.6 AccountServiceImpl文件添加注解

  • @Service("accountService")
package xyz.slienceme.service.impl;
import org.springframework.stereotype.Service;
import xyz.slienceme.domain.Account;
import xyz.slienceme.service.AccountService;
import java.util.List;

/**
 * @Author slience_me
 * @Time : 2021/7/4  9:04
 */
@Service("accountService")
public class AccountServiceImpl implements AccountService {
}

1.3.7 编写测试方法

package xyz.slienceme.test;
import xyz.slienceme.service.AccountService;
import org.junit.Test;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;

public class TestSpring {

    @Test
    public void run1(){
        // 加载配置文件
        ApplicationContext ac = new ClassPathXmlApplicationContext("classpath:applicationContext.xml");
        // 获取对象
        AccountService as = (AccountService) ac.getBean("accountService");
        // 调用方法
        as.findAll();
    }

}

1.3.8 在resources中创建log4j.properties

# Set root category priority to INFO and its only appender to CONSOLE.
#log4j.rootCategory=INFO, CONSOLE            debug   info   warn error fatal
log4j.rootCategory=info, CONSOLE, LOGFILE

# Set the enterprise logger category to FATAL and its only appender to CONSOLE.
log4j.logger.org.apache.axis.enterprise=FATAL, CONSOLE

# CONSOLE is set to be a ConsoleAppender using a PatternLayout.
log4j.appender.CONSOLE=org.apache.log4j.ConsoleAppender
log4j.appender.CONSOLE.layout=org.apache.log4j.PatternLayout
log4j.appender.CONSOLE.layout.ConversionPattern=%d{ISO8601} %-6r [%15.15t] %-5p %30.30c %x - %m\n

# LOGFILE is set to be a File appender using a PatternLayout.
log4j.appender.LOGFILE=org.apache.log4j.FileAppender
log4j.appender.LOGFILE.File=d:\axis.log
log4j.appender.LOGFILE.Append=true
log4j.appender.LOGFILE.layout=org.apache.log4j.PatternLayout
log4j.appender.LOGFILE.layout.ConversionPattern=%d{ISO8601} %-6r [%15.15t] %-5p %30.30c %x - %m\n

2. Spring整合SpringMVC框架

2.1 相关步骤

2.1.1 在webapp/WEB-INF配置web.xml

<!DOCTYPE web-app PUBLIC
 "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN"
 "http://java.sun.com/dtd/web-app_2_3.dtd" >

<web-app>
  <display-name>Archetype Created Web Application</display-name>
  <!-- 配置前端控制器 -->
  <servlet>
    <servlet-name>dispatcherServlet</servlet-name>
    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
    <!--  加载springmvc.xml配置文件  -->
    <init-param>
      <param-name>contextConfigLocation</param-name>
      <param-value>classpath:springmvc.xml</param-value>
    </init-param>
    <!--  启动服务器，创建该servlet  -->
    <load-on-startup>1</load-on-startup>
  </servlet>
  <servlet-mapping>
    <servlet-name>dispatcherServlet</servlet-name>
    <url-pattern>/</url-pattern>
  </servlet-mapping>
  <!-- 解决中文乱码的过滤器 -->
  <filter>
    <filter-name>characterEncodingFilter</filter-name>
    <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
    <init-param>
      <param-name>encoding</param-name>
      <param-value>UTF-8</param-value>
    </init-param>
  </filter>
  <filter-mapping>
    <filter-name>characterEncodingFilter</filter-name>
    <url-pattern>/*</url-pattern>
  </filter-mapping>
</web-app>

2.1.2 在resources中创建配置springmvc.xml

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:mvc="http://www.springframework.org/schema/mvc" xmlns:context="http://www.springframework.org/schema/context"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xsi:schemaLocation="
        http://www.springframework.org/schema/beans
        http://www.springframework.org/schema/beans/spring-beans.xsd
        http://www.springframework.org/schema/mvc
        http://www.springframework.org/schema/mvc/spring-mvc.xsd
        http://www.springframework.org/schema/context
        http://www.springframework.org/schema/context/spring-context.xsd">

    <!--开启注解扫描，只扫描Controller注解-->
    <context:component-scan base-package="xyz.slienceme ">
        <context:include-filter type="annotation" expression="org.springframework.stereotype.Controller" />
    </context:component-scan>

    <!--配置的视图解析器对象-->
    <bean id="internalResourceViewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        <property name="prefix" value="/WEB-INF/pages/"/>
        <property name="suffix" value=".jsp"/>
    </bean>

    <!--过滤静态资源-->
    <mvc:resources location="/css/" mapping="/css/**" />
    <mvc:resources location="/images/" mapping="/images/**" />
    <mvc:resources location="/js/" mapping="/js/**" />

    <!--开启SpringMVC注解的支持-->
    <mvc:annotation-driven/>

</beans>

2.1.3 在webapp中编写index.jsp

<%--
  @Author: slience_me
  @Time: 2021/7/4 9:34
--%>
<%@ page contentType="text/html;charset=UTF-8" language="java" %>
<html>
<head>
    <title>Title</title>
</head>
<body>
<a href="account/findAll">测试查询</a>

<h3>测试包</h3>

<form action="account/save" method="post">
    姓名：<input type="text" name="name"/><br/>
    金额：<input type="text" name="money"/><br/>
    <input type="submit" value="保存"/><br/>
</form>

</body>
</html>

2.1.4 xyz.slienceme.controller.AccountController;

package xyz.slienceme.controller;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
/**
 * @Author slience_me
 * @Time : 2021/7/4  9:08
 */
@Controller
@RequestMapping("/account")
public class AccountController {

    @RequestMapping("/findAll")
    public String findAll(){
        System.out.println("表现层：查询所有账户信息。。。");
        return "list";
    }
}

2.1.4 在webapp/WEB-INF/pages下创建list.jsp

<%--
  @Author: slience_me
  @Time: 2021/7/4 9:41
--%>
<%@ page contentType="text/html;charset=UTF-8" language="java" %>
<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>
<html>
<head>
    <title>Title</title>
</head>
<body>
    <h3>查询所有的帐户</h3>

    <c:forEach items="${list}" var="account">
        ${account.name}
    </c:forEach>

</body>
</html>

2.1.5 开启tomcat服务器测试一下

  • index.jsp Alt Text
  • list.jsp Alt Text

    2.1.6 在web.xml添加监听器配置并指定加载路径

<!--配置Spring的监听器，默认只加载WEB-INF目录下的applicationContext.xml配置文件-->
<listener>
    <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>
<!--设置配置文件的路径-->
<context-param>
    <param-name>contextConfigLocation</param-name>
    <param-value>classpath:applicationContext.xml</param-value>
</context-param>

2.1.7 给AccountController中业务层注入

package xyz.slienceme.controller;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import xyz.slienceme.domain.Account;
import xyz.slienceme.service.AccountService;
import java.util.List;

/**
 * @Author slience_me
 * @Time : 2021/7/4  9:08
 */
@Controller
@RequestMapping("/account")
public class AccountController {

    @Autowired
    private AccountService accountService;

    @RequestMapping("/findAll")
    public String findAll(){
        System.out.println("表现层：查询所有账户信息。。。");
        //调用service的方法
        List<Account> accounts = accountService.findAll();
        return "list";
    }
}

3. Spring整合MyBatis框架

3.1 相关步骤

3.1.1 对于AccountDao接口编写

package xyz.slienceme.dao;
import org.apache.ibatis.annotations.Insert;
import org.apache.ibatis.annotations.Select;
import xyz.slienceme.domain.Account;

import java.util.List;

/**
 * @Author slience_me
 * @Time : 2021/7/4  9:02
 * 账户dao接口
 */
public interface AccountDao {

    /**
     * 查询所有账户信息
     * @return
     */
    @Select("select * from account")
    public List<Account> findAll();

    /**
     * 保存账户信息
     * @param account
     */
    @Insert("insert into account (name,money) value(#{name},#{money})")
    public void saveAccount(Account account);
}

3.1.2 在resources下配置SqlMapConfig.xml文件

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE configuration
        PUBLIC "-//mybatis.org//DTD Config 3.0//EN"
        "http://mybatis.org/dtd/mybatis-3-config.dtd">
<configuration>

    <!--  引入外部配置文件  -->
    <properties resource="jdbcConfig.properties"/>

    <!--  配置环境  -->
    <environments default="mysql">
        <environment id="mysql">
            <transactionManager type="JDBC"/>
            <dataSource type="POOLED">
                <property name="driver" value="${jdbc.driver}"/>
                <property name="url" value="${jdbc.url}"/>
                <property name="username" value="${jdbc.username}"/>
                <property name="password" value="${jdbc.password}"/>
            </dataSource>
        </environment>
    </environments>
    <!--  指定带有注解的dao接口所在位置  -->
    <mappers>
        <package name="xyz.slienceme.dao" />
    </mappers>
</configuration>

3.1.3 在resources下配置jdbcConfig.properties文件

jdbc.driver=com.mysql.cj.jdbc.Driver
jdbc.url=jdbc:mysql://localhost:3306/slience_me
jdbc.username=*******
jdbc.password=*******

3.1.4 测试类的编写

package xyz.slienceme.test;
import xyz.slienceme.dao.AccountDao;
import xyz.slienceme.domain.Account;
import org.apache.ibatis.io.Resources;
import org.apache.ibatis.session.SqlSession;
import org.apache.ibatis.session.SqlSessionFactory;
import org.apache.ibatis.session.SqlSessionFactoryBuilder;
import org.junit.Test;
import java.io.InputStream;
import java.util.List;

public class TestMyBatis {

    /**
     * 测试查询
     * @throws Exception
     */
    @Test
    public void run1() throws Exception {
        // 加载配置文件
        InputStream in = Resources.getResourceAsStream("SqlMapConfig.xml");
        // 创建SqlSessionFactory对象
        SqlSessionFactory factory = new SqlSessionFactoryBuilder().build(in);
        // 创建SqlSession对象
        SqlSession session = factory.openSession();
        // 获取到代理对象
        AccountDao dao = session.getMapper(AccountDao.class);
        // 查询所有数据
        List<Account> list = dao.findAll();
        for(Account account : list){
            System.out.println(account);
        }
        // 关闭资源
        session.close();
        in.close();
    }

    /**
     * 测试保存
     * @throws Exception
     */
    @Test
    public void run2() throws Exception {
        Account account = new Account();
        account.setName("slienceme");
        account.setMoney(400d);

        // 加载配置文件
        InputStream in = Resources.getResourceAsStream("SqlMapConfig.xml");
        // 创建SqlSessionFactory对象
        SqlSessionFactory factory = new SqlSessionFactoryBuilder().build(in);
        // 创建SqlSession对象
        SqlSession session = factory.openSession();
        // 获取到代理对象
        AccountDao dao = session.getMapper(AccountDao.class);

        // 保存
        dao.saveAccount(account);

        // 提交事务
        session.commit();

        // 关闭资源
        session.close();
        in.close();
    }

}

3.2 配置Spring整合MyBatis框架

3.2.1 配置applicationContext.xml并删除SqlMapConfig.xml

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

        <context:exclude-filter type="annotation" expression="org.springframework.stereotype.Controller"/>
    </context:component-scan>

    <!--Spring整合MyBatis框架-->
    <!--配置连接池-->
    <bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource">
        <property name="driverClass" value="com.mysql.cj.jdbc.Driver"/>
        <property name="jdbcUrl" value="jdbc:mysql://localhost:3306/ssm"/>
        <property name="user" value="*******"/>
        <property name="password" value="*******"/>
    </bean>

    <!--配置SqlSessionFactory工厂-->
    <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
        <property name="dataSource" ref="dataSource" />
    </bean>

    <!--配置AccountDao接口所在包-->
    <bean id="mapperScanner" class="org.mybatis.spring.mapper.MapperScannerConfigurer">
        <property name="basePackage" value="xyz.slienceme.dao"/>
    </bean>
</beans>

3.2.2 给AccountDao添加注解@Repository

@Repository("accountDao")
public interface AccountDao {
}

3.2.3 给AccountService设置AccountDao注入

package xyz.slienceme.service.impl;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
import xyz.slienceme.dao.AccountDao;
import xyz.slienceme.domain.Account;
import xyz.slienceme.service.AccountService;
import java.util.List;

/**
 * @Author slience_me
 * @Time : 2021/7/4  9:04
 */
@Service("accountService")
public class AccountServiceImpl implements AccountService {

    @Autowired
    private AccountDao accountDao;

    @Override
    public List<Account> findAll() {
        System.out.println("业务层:查询所有账户信息。。。");
        return accountDao.findAll();
    }

    @Override
    public void saveAccount(Account account) {
        System.out.println("业务层:保存账户信息。。。");
        accountDao.saveAccount(account);
    }
}

3.2.4 修改AccountController

package xyz.slienceme.controller;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;
import xyz.slienceme.domain.Account;
import xyz.slienceme.service.AccountService;

import java.util.List;

/**
 * @Author slience_me
 * @Time : 2021/7/4  9:08
 */
@Controller
@RequestMapping("/account")
public class AccountController {

    @Autowired
    private AccountService accountService;

    @RequestMapping("/findAll")
    public String findAll(Model model){
        System.out.println("表现层：查询所有账户信息。。。");
        //调用service的方法
        List<Account> list = accountService.findAll();
        model.addAttribute("list",list);
        return "list";
    }
}

4. Spring框架代码的编写

4.1 相关步骤

4.1.1 配置applicationContext.xml

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xmlns:context="http://www.springframework.org/schema/context"
       xmlns:aop="http://www.springframework.org/schema/aop"
       xmlns:tx="http://www.springframework.org/schema/tx"
       xsi:schemaLocation="http://www.springframework.org/schema/beans

	http://www.springframework.org/schema/aop/spring-aop.xsd
	http://www.springframework.org/schema/tx
	http://www.springframework.org/schema/tx/spring-tx.xsd">

    <!-- 开启注解扫描，要扫描的是service和dao层的注解，要忽略web层注解，因为web层让SpringMVC框架去管理 -->
    <context:component-scan base-package="xyz.slienceme">
        <!-- 配置要忽略的注解 -->
        <context:exclude-filter type="annotation" expression="org.springframework.stereotype.Controller"/>
    </context:component-scan>

    <!--Spring整合MyBatis框架-->
    <!--配置连接池-->
    <bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource">
        <property name="driverClass" value="com.mysql.cj.jdbc.Driver"/>
        <property name="jdbcUrl" value="jdbc:mysql://localhost:3306/ssm"/>
        <property name="user" value="*******"/>
        <property name="password" value="**********"/>
    </bean>

    <!--配置SqlSessionFactory工厂-->
    <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
        <property name="dataSource" ref="dataSource" />
    </bean>

    <!--配置AccountDao接口所在包-->
    <bean id="mapperScanner" class="org.mybatis.spring.mapper.MapperScannerConfigurer">
        <property name="basePackage" value="xyz.slienceme.dao"/>
    </bean>

    <!--配置Spring框架声明式事务管理-->
    <!--配置事务管理器-->
    <bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
        <property name="dataSource" ref="dataSource" />
    </bean>

    <!--配置事务通知-->
    <tx:advice id="txAdvice" transaction-manager="transactionManager">
        <tx:attributes>
            <tx:method name="find*" read-only="true"/>
            <tx:method name="*" isolation="DEFAULT"/>
        </tx:attributes>
    </tx:advice>

    <!--配置AOP增强-->
    <aop:config>
        <aop:advisor advice-ref="txAdvice" pointcut="execution(* xyz.slienceme.service.impl.*ServiceImpl.*(..))"/>
    </aop:config>
</beans>

4.1.2 AccountController添加保存

package xyz.slienceme.controller;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;
import xyz.slienceme.domain.Account;
import xyz.slienceme.service.AccountService;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import java.io.IOException;
import java.util.List;

/**
 * @Author slience_me
 * @Time : 2021/7/4  9:08
 */
@Controller
@RequestMapping("/account")
public class AccountController {

    @Autowired
    private AccountService accountService;

    @RequestMapping("/findAll")
    public String findAll(Model model){
        System.out.println("表现层：查询所有账户信息。。。");
        //调用service的方法
        List<Account> list = accountService.findAll();
        model.addAttribute("list",list);
        return "list";
    }

    /**
     * 保存
     * @return
     */
    @RequestMapping("/save")
    public void save(Account account, HttpServletRequest request, HttpServletResponse response) throws IOException {
        accountService.saveAccount(account);
        response.sendRedirect(request.getContextPath()+"/account/findAll");
    }
}

4.1.3 修改index.jsp测试提交表单

<%--
