入门级别的springboot多模块项目搭建

一。创建父工程

1.1File-》New-》Project

1.2 选中Spring Iniaializr，sdk选中1.8

1.3 填写信息及选择java版本，下一步

1.4 其他选项不用勾选，选择所需的Springboot版本，我这里选择2.3.7，接下来点击下一步

1.5 选择项目保存的路径，点击完成

1.6 删除无用的文件夹及文件（.mvn、src、mvnw、mvnw.cmd）

二。创建子工程，先创建公共模块

2.1选中父工程，右键 New-》Module

2.2 选择maven，sdk，点击下一步

2.3 输入项目名danyu-common，点击完成

三。创建子工程（danyu-web）

3.1 过程步骤跟第二步一样

四。修改各类配置文件

4.1 修改父工程（danyu）的pom.xml文件

4.2 修改子工程（danyu-common）的pom.xml文件

<?xml version="1.0" encoding="UTF-8"?>

</project>

4.3 修改子工程（danyu-web）的pom.xml文件

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

            <type>jar</type>
            <!--            <classifier>classes</classifier>-->
        </dependency>
 
    </dependencies>
 
</project>

五.添加application项目入口类

5.1 在danyu-web中，展开src文件夹，选中java右键，选择Mark Directory as->Sources Root

5.2 新建路径包

5.3 输入包名：com.danyu.web,之后回车完成新建

5.4新建web入口类（DanyuWebApplication.java）

package com.danyu.web;
 
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
 
@SpringBootApplication
public class DanyuWebApplication {
    public static void main(String[] args) {
        SpringApplication.run(DanyuWebApplication.class, args);
    }
}

这一步，如果SpringApplication和SpringBootApplication引入的类包报错，则选中父工程，右键maven-》Reimport，更新重新导入一下

六。添加测试的控制器类

在com.danyu.web下添加包（controller），新建java类（TestController）

package com.danyu.web.controller;
 
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;
 
/**
 * @author danyu
 * @date 2020/01/01
 */
@RestController
@RequestMapping("/manage")
public class TestController {
 
    @GetMapping("/test")
    public String test() {
        return "访问控制器成功";
    }
 
}

七。添加springboot配置文件类

7.1 在danyu-web子工程下的resources文件夹，选中右键New-》FIle

输入文件名application.yml

打开application.yml文件，输入

# 开发环境配置
server:
  # 服务器的HTTP端口，默认为8080
  port: 8080
  servlet:
    # 应用的访问路径
    context-path: /danyu
 
spring:
  datasource:
    name: test
    url: jdbc:mysql://localhost:3306/test
    username: root
    password: root
