一般是域名反写 com.zzjsonartfactId 功能命名version 版本号packaging 打包方式 默认是jardependencyManagement 只能出现在父pom 统一版本号 声明 (子POM里用到再引)Dependency Type 默认jarscopecompile 默认 编译（maven编译整个项目） 例如spring-coretest 测试provided 编译 例如 servlet,tomcat已经有了 打包不会打进去，相当于compile但是在打包阶段做了exclude操作runtime 运行时 例如JDBC驱动实现system 本地一些jar 例如短信jar依赖传递compile:编译依赖范围，在编译，测试，运行时都需要。test: 测试依赖范围，测试时需要。编译和运行不需要。如Junitruntime: 运行时依赖范围，测试和运行时需要。编译不需要。如JDBC驱动包provided:已提供依赖范围，编译和测试时需要。运行时不需要。如servlet-apisystem:系统依赖范围。本地依赖，不在maven中央仓库。第一列表示直接依赖的scope，第一行表示间接依赖的scope
