继承springboot父级项目  提供相关的Maven 默认依赖

    <parent>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>
        <version>2.1.0.RELEASE</version>
        <relativePath/>
    </parent>

使用之后，常用的Jar包依赖 可以省去 version （版本）配置会从父级项目中继承父级maven 依赖的版本 

 如果不想使用默认的版本依赖，可以指定版本并且会覆盖父级的依赖项 

  <spring.version>1.8</spring.version> 

 

     属性配置

    <properties>
        <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
        <project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding>
        <java.version>1.8</java.version>
    </properties>

 

<dependencies>  </dependencies>  标签中是项目maven依赖
