SpringBoot搭建基于Spring+SpringMvc+Mybatis的REST服务

Maven Plugin管理

通常，让你的Maven POM文件继承 spring-boot-starter-parent，并声明一个或多个 Starter POMs依赖即可。

spring-boot-starter-parent

1 <parent>
2      <groupId>org.springframework.boot</groupId>
3      <artifactId>spring-boot-starter-parent</artifactId>
4      <version>1.5.6.RELEASE</version>
5 </parent>
