# Spring Boot 2 多模块项目搭建 #

1.  新建一个Maven父项目spring-boot-parent,继承spring-boot-starter-parent,

<parent>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-parent</artifactId>
            <version>2.1.1.RELEASE</version>
            <relativePath/> 
        </parent>

修改打包方式:

引入需要的依赖:

<dependencies>
            <dependency>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-starter</artifactId>
            </dependency>
            <dependency>
                <groupId>org.projectlombok</groupId>
                <artifactId>lombok</artifactId>
                <optional>true</optional>
            </dependency>
        </dependencies>

1.  新建子模块spring-boot-pojo(可以直接用IDEA 新建一个springboot项目:File->New->Module->Spring Initializr,然后再修改),添加父项目

<parent>
            <groupId>com.multi</groupId>
            <artifactId>spring-boot-parent</artifactId>
            <version>1.0-SNAPSHOT</version>
        </parent>

删除SpringBoot Maven插件(非服务模块都要删除)

<build>
            <plugins>
                <plugin>
                    <groupId>org.springframework.boot</groupId>
                    <artifactId>spring-boot-maven-plugin</artifactId>
                </plugin>
            </plugins>
        </build>

同样方式创建spring-boot-dao模块(继承spring-boot-parent父模块,依赖spring-boot-pojo模块,删除springboot maven插件)

<dependencies>
            <dependency>
                <groupId>com.multi</groupId>
                <artifactId>spring-boot-pojo</artifactId>
                <version>0.0.1-SNAPSHOT</version>
            </dependency>
    
            <dependency>
                <groupId>org.mybatis.spring.boot</groupId>
                <artifactId>mybatis-spring-boot-starter</artifactId>
                <version>1.3.2</version>
            </dependency>
    
            <dependency>
                <groupId>mysql</groupId>
                <artifactId>mysql-connector-java</artifactId>
                
            </dependency>
        </dependencies>

1.  新建一个springboot模块spring-boot-service,修改父模块继承关系,

<parent>
            <groupId>com.multi</groupId>
            <artifactId>spring-boot-parent</artifactId>
            <version>1.0-SNAPSHOT</version>
        </parent>

添加子模块依赖：

<dependency>
                <groupId>com.multi</groupId>
                <artifactId>spring-boot-pojo</artifactId>
                <version>0.0.1-SNAPSHOT</version>
            </dependency>
            <dependency>
                <groupId>com.multi</groupId>
                <artifactId>spring-boot-dao</artifactId>
                <version>0.0.1-SNAPSHOT</version>
            </dependency>

设置mapper扫描位置

@SpringBootApplication
    @MapperScan(value = "com.multi.dao")//指定mapper扫描位置,否则启动无法注入mapper的bean
    public class SpringBootServiceApplication { 
    
        public static void main(String[] args) { 
            SpringApplication.run(SpringBootServiceApplication.class, args);
        }
    
    }

注:这里为了方便测试,.就直接在service模块里写controller进行简单测试了.
