springboot+idea+maven 多模块项目搭建的详细过程（连接数据库进行测试）
作者：fc方的程序日记
这篇文章主要介绍了springboot+idea+maven 多模块项目搭建的详细过程（连接数据库进行测试）,本文通过图文并茂的形式给大家介绍的非常详细，对大家的学习或工作具有一定的参考借鉴价值，需要的朋友可以参考下
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
<?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> <artifactId>honor-common</artifactId> <dependencies> <dependency> <groupId>org.projectlombok</groupId> <artifactId>lombok</artifactId> </dependency> <dependency> <groupId>com.baomidou</groupId> <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" 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> <artifactId>honor-dao</artifactId> <dependencies> <dependency> <groupId>com.honor</groupId> <artifactId>honor-common</artifactId> </dependency> <dependency> <groupId>com.baomidou</groupId> <artifactId>mybatis-plus-boot-starter</artifactId> </dependency> <dependency> <groupId>com.baomidou</groupId> <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.
<?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 https://maven.apache.org/xsd/maven-4.0.0.xsd"> <modelVersion>4.0.0</modelVersion> <parent> <artifactId>honor-manager</artifactId> <groupId>com.honor.manager</groupId> <version>1.0-SNAPSHOT</version> </parent> <groupId>com.honor.manager</groupId> <artifactId>honor-manager-boot</artifactId> <version>0.0.1-SNAPSHOT</version> <name>honor-manager-boot</name> <description>Demo project for Spring Boot</description> <properties> <java.version>1.8</java.version> </properties> <dependencies> <dependency> <groupId>com.honor.manager</groupId> <artifactId>honor-manager-user1</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>mysql</groupId> <artifactId>mysql-connector-java</artifactId> <scope>runtime</scope> </dependency> <dependency> <groupId>org.junit.jupiter</groupId> <artifactId>junit-jupiter-api</artifactId> </dependency> <dependency> <groupId>com.alibaba</groupId> <artifactId>druid-spring-boot-starter</artifactId> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-web</artifactId> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-test</artifactId> <scope>test</scope> <exclusions> <exclusion> <groupId>org.junit.vintage</groupId> <artifactId>junit-vintage-engine</artifactId> </exclusion> </exclusions> </dependency> <dependency> <groupId>org.junit.jupiter</groupId> <artifactId>junit-jupiter</artifactId> <version>RELEASE</version> <scope>test</scope> </dependency> </dependencies> <build> <plugins> <plugin> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-maven-plugin</artifactId> </plugin> </plugins> </build> </project>
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！
