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>
 <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"

 <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>

 </dependency>
 <dependency>

 </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

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

然后搭建 beans

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

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

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

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

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

@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

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

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
