文章标签 maven项目数据层服务层 IDEA Springboot Maven 多模块项目配置 文章分类 架构后端开发

说明

多模块聚合项目中各个项目的pom配置
错过项目创建过程的可以点击这里《maven+springboot构建多模块聚合项目过程（IDEA版）》

配置说明

1.对根项目的配置改造

根项目需要对各个子模块的包和插件进行管理，所以根项目中要将可能用到的包和插件全部列出。

maven项目数据层服务层 maven配置数据库_多模块项目配置

maven项目数据层服务层 maven配置数据库_Maven_02

maven项目数据层服务层 maven配置数据库_IDEA_03

2.对common模块配置的改造

common模块需要存储VO类，引入了lombok包，具体内容见下方配置文件。

3.对mapper模块配置的改造

mapper模块需要引入common模块，具体内容见下方配置文件。

4.对service模块配置的改造

service模块需要引入common和mapper模块，具体内容见下方配置文件。

5.对api模块配置的改造

api模块需要引入common和service模块，具体内容见下方配置文件。

配置文件

1.根项目配置pom文件

#数据源在启动的这个模块项目中配置就可以了
spring.datasource.driverClassName=com.mysql.jdbc.Driver
#改成自己的数据库地址
spring.datasource.url=jdbc:mysql://127.0.0.1:3306/数据库名?useSSL=false
#改成自己的用户名
spring.datasource.username=用户名
#改成自己的密码
spring.datasource.password=密码
#数据源类型为阿里巴巴的druid
spring.datasource.type=com.alibaba.druid.pool.DruidDataSource

#对VO类起别名
mybatis.type-aliases-package=com.fanyi.vo

#配置集成tomcat的端口，可自行修改
server.port=3333

各个模块的功能不同，使用的包和插件也不相同，可以分别进行依赖管理。
