一、多模块项目构建
1. 先建立父级目录demo-parent
2. 把父级目录src删除，再建立子级模块
3. 建立子级模块model,dao,service,common.utils等相同步骤
4. 建立启动模块boot, 创建Spring Boot 启动类
package com.example;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
/**
* Hello world!
*
*/
@SpringBootApplication(scanBasePackages = "com.example")
public class App
{
public static void main( String[] args )
{
SpringApplication.run(App.class, args);
}
}
5. 修改依赖关系
5.1 根模块root的maven
<parent>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-parent</artifactId>
<version>2.7.7</version>
<relativePath/> <!-- lookup parent from repository -->
</parent>
<groupId>com.example</groupId>
<artifactId>demo-parent</artifactId>
<version>0.0.1-SNAPSHOT</version>
<packaging>pom</packaging>
<name>demo-parent</name>
<description>demo-parent</description>
<modules>
<module>demo-model</module>
<module>demo-dao</module>
<module>demo-service</module>
<module>demo-common</module>
<module>demo-utils</module>
<module>demo-boot</module>
</modules>
5.2 根模块打包插件
<build>
<plugins>
<plugin>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-maven-plugin</artifactId>
</plugin>
</plugins>
</build>
5.3 启动模块boot，记得添加web的controller的依赖
<dependencies>
<dependency>
<groupId>com.example</groupId>
<artifactId>demo-web</artifactId>
<version>${project.parent.version}</version>
</dependency>
</dependencies>
<build>
<plugins>
<plugin>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-maven-plugin</artifactId>
<configuration>
<mainClass>
com.example.demo.BootApplication
</mainClass>
</configuration>
</plugin>
</plugins>
</build>
5.4 其他没有启动类的模块添加以下
<build>
<plugins>
<plugin>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-maven-plugin</artifactId>
<configuration>
<skip>
true
</skip>
</configuration>
</plugin>
</plugins>
</build>
5.5 然后逐一添加依赖
web依赖 service
<dependency>
<groupId>com.example</groupId>
<artifactId>demo-service</artifactId>
<version>${project.parent.version}</version>
</dependency>
service依赖 dao , common, utils ,model
<dependency>
<groupId>com.example</groupId>
<artifactId>demo-dao</artifactId>
<version>${project.parent.version}</version>
</dependency>
<dependency>
<groupId>com.example</groupId>
<artifactId>demo-utils</artifactId>
<version>${project.parent.version}</version>
</dependency>
<dependency>
<groupId>com.example</groupId>
<artifactId>demo-model</artifactId>
<version>${project.parent.version}</version>
</dependency>
<dependency>
<groupId>com.example</groupId>
<artifactId>demo-common</artifactId>
<version>${project.parent.version}</version>
</dependency>
dao依赖 model 等
boot启动模块依赖 web 的controller，其他自行添加依赖
6. 运行测试
6.1 dao下创建
package xyz.slienceme.wms;
import org.springframework.stereotype.Repository;
import org.springframework.web.bind.annotation.Mapping;
@Repository
public class DaoTest {
public String DaoTest1(){
System.out.println("dao打印了");
return "www";
}
}
6.2 service下创建
package xyz.slienceme.wms;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
@Service
public class ServiceTest {
@Autowired
DaoTest daoTest;
public void ServiceTest1(){
System.out.println("ServiceTest打印了");
String s = daoTest.DaoTest1();
S
6.3 web下创建
package xyz.slienceme.wms;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.RestController;
import xyz.slienceme.wms.ServiceTest;
@RestController
public class ControllerTest {
@Autowired
ServiceTest serviceTest;
@RequestMapping(value = "/demo", method = RequestMethod.GET)
String ControllerTest1(){
serviceTest.ServiceTest1();
return "成功";
}
}
6.4 启动boot按钮
