springboot+idea+maven 多模块项目搭建的详细过程（连接数据库进行测试）

创建之前项目之前 记得改一下 maven  提高下载Pom速度 

 记得 setting 中要改 maven  改成 阿里云的。具体方法 网上查第一步 搭建parents 项目，为maven项目 ，不为springboot 项目 记得修改groupId 

第二步 搭建多个子模块， honor-dao   honor-manager   honor-common记得创建 honor-manager 的时候 要把他的gruopId 改成com.honor.manager

这里爆红的原因是 因为 我做到后面然后忘记截屏了，返回来做。实际我已经创建了 ，所以这个步骤是对的。按照这个做法，创建 honor-dao   honor-manager   honor-common，记得创建 honor-manager 的时候 要把他的gruopId 改成com.honor.manager

第三步  在 honor-manager 下分别创建 honor-manager-fc（maven）  honor-manager-user（maven） honor-manager-boot (springboot,记得要使用springboot创建)创建时候 有两个坑 第一个是 父级  别选错 。他一般会默认 选第一级别，就是 honor  但是我们要继承的是 honor-manager第二个是路径 别写错

第四步 开始对各大 Pom 进行整合  dao  中一般需要引入 common  ，common 一般不需要引 其他模块，然后呢 manager 中要同时引入dao  和 common第一个是  honor  父级的 pom

第二个是honor-common

 <artifactId>mybatis-plus-annotation</artifactId>
 <version>3.1.0</version>
 <scope>compile</scope>
 </dependency>
 </dependencies>
</project>

 第三个是honor-dao的 pom

<?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"

 <dependency>

 <artifactId>mybatis-plus-generator</artifactId>
 </dependency>
 <dependency>
 <groupId>mysql</groupId>
 <artifactId>mysql-connector-java</artifactId>
 </dependency>
 </dependencies>
</project>

第四个是honor-manager的 

<?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"
 xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
 <parent>
 <artifactId>phone</artifactId>
 <groupId>com.honor</groupId>
 <version>1.0-SNAPSHOT</version>
 </parent>
 <modelVersion>4.0.0</modelVersion>
 
 
 <groupId>com.honor.manager</groupId>
 <artifactId>honor-manager</artifactId>
 <packaging>pom</packaging>
 <modules>
 <module>honor-manager-txn1</module>
 <module>honor-manager-user1</module>
 <module>honor-manager-boot</module>
 </modules>
 <dependencies>
 <dependency>
 <groupId>com.honor</groupId>
 <artifactId>honor-common</artifactId>
 </dependency>
 <dependency>
 <groupId>com.honor</groupId>
 <artifactId>honor-dao</artifactId>
 </dependency>
 <dependency>
 <groupId>com.baomidou</groupId>
 <artifactId>mybatis-plus-boot-starter</artifactId>
 </dependency>
 <dependency>
 <groupId>org.springframework.boot</groupId>
 <artifactId>spring-boot-starter-web</artifactId>
 </dependency>
 </dependencies>
 <dependencyManagement>
 <dependencies>
 <dependency>
 <groupId>com.honor.manager</groupId>
 <artifactId>honor-manager-boot</artifactId>
 <version>1.0-SNAPSHOT</version>
 </dependency>
 <dependency>
 <groupId>com.honor.manager</groupId>
 <artifactId>>honor-manager-txn1</artifactId>
 <version>1.0-SNAPSHOT</version>
 </dependency>
 <dependency>
 <groupId>com.honor.manager</groupId>
 <artifactId>>honor-manager-user1</artifactId>
 <version>1.0-SNAPSHOT</version>
 </dependency>
 </dependencies>
 </dependencyManagement>
</project>

然后 是 honor-manager-user

<?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"
 xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
 <parent>
 <artifactId>honor-manager</artifactId>
 <groupId>com.honor.manager</groupId>
 <version>1.0-SNAPSHOT</version>
 </parent>
 <modelVersion>4.0.0</modelVersion>
 <artifactId>honor-manager-user1</artifactId>
 <dependencies>
 <dependency>
 <groupId>org.springframework.boot</groupId>
 <artifactId>spring-boot-starter-web</artifactId>
 </dependency>
 </dependencies>
</project>

然后 是honor-manager-boot记得boot 要引入 txn1 和 user的依赖，记得要把parents 要改一下，是为honor-manager.

  第二阶段  开始测试 首先搭建数据库，做个简单的User 表测试就行了 

然后搭建 beans 

User 的内容

package com.honor.common.beans;
import com.baomidou.mybatisplus.annotation.IdType;
import com.baomidou.mybatisplus.annotation.TableId;
import lombok.Data;
import lombok.EqualsAndHashCode;
import lombok.experimental.Accessors;
@Data
@EqualsAndHashCode(callSuper = false)
@Accessors(chain = true)
public class User {
 @TableId(type = IdType.AUTO)
 private Integer id;
 private String username;
 private String password;
}

第二部 dao层

UserMapper接口

package com.honor.mapper;
import com.baomidou.mybatisplus.core.mapper.BaseMapper;
import com.honor.common.beans.User;
import org.apache.ibatis.annotations.Mapper;
import java.util.List;
@Mapper
public interface UserMapper extends BaseMapper<User> {
}

UserMapper.xml

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN" "http://mybatis.org/dtd/mybatis-3-mapper.dtd">
<mapper namespace="com.honor.mapper.UserMapper">
 <resultMap id="User" type="com.eft.common.beans.User"/>
</mapper>

第三部分 springboot 的application 中加入扫描包的注解

@ServletComponentScan
 
@MapperScan("com.honor.mapper")

  然后编写application.yml 文件 

server:
 port: 8880
 servlet:
 context-path: /honor-manager
 
spring:
 application:
 name: users
 datasource:
 type: com.alibaba.druid.pool.DruidDataSource
 driver-class-name: com.mysql.jdbc.Driver
 url: jdbc:mysql://localhost:3306/eft?characterEncoding=UTF-8&serverTimezone=UTC&useSSL=true
 username: root
 password: 111111
mybatis-plus:
 mapper-locations:
 - classpath*:com/honor/mapper/*.xml
 check-config-location: true
debug: true

紧接着编写 userController 进行测试一定要前缀一样！这里注意要前缀一样，要不 扫描不到    

UserController代码

package com.honor.manager.controller;
import com.honor.common.beans.User;
import com.honor.mapper.UserMapper;
import org.springframework.http.MediaType;
import org.springframework.web.bind.annotation.*;
import javax.annotation.Resource;
import java.util.Map;
@RestController
public class UserController {
 @Resource
 UserMapper userMapper;
 @RequestMapping(
 value = "/api/user",
 method = RequestMethod.GET,
 produces = MediaType.APPLICATION_JSON_UTF8_VALUE
 )
 @ResponseBody
 public User read(@RequestParam Map<String, Object> params) {
 return userMapper.selectById("1");
 }
 @GetMapping("/api/test")
 public String hello() {
 return "hello";
 }
}

访问 http://localhost:8880/honor-manager/api/user

 自

此 多级模块的项目就搭建成功了！
