maven中的依赖范围（生效时间点）

  • compile 编译, 测试 打包部署有效

  • ==provided 编译, 测试 有效, 不会打包进去的==

  • test 测试有效

  • runtime 编译无效, 测试 打包部署有效

 

servlet-api就是编译和测试有用，在运行时不用（tomcat容器已提供）

<dependency>
    <groupId>javax.servlet</groupId>
    <artifactId>javax.servlet-api</artifactId>
    <version>3.1.0</version>
    <scope>provided</scope>
</dependency>

导入junit坐标依赖

<dependency>
    <groupId>junit</groupId>
    <artifactId>junit</artifactId>
    <version>4.12</version>
    <scope>test</scope>
</dependency>

JDK编译版本的插件

 <!--jdk编译插件-->
      <plugin>
        <groupId>org.apache.maven.plugins</groupId>
        <artifactId>maven-compiler-plugin</artifactId>
        <version>3.2</version>
        <configuration>
          <source>1.8</source>
          <target>1.8</target>
          <encoding>utf-8</encoding>
        </configuration>
      </plugin>

Tomcat7服务端的插件

        <artifactId>tomcat7-maven-plugin</artifactId>
        <configuration>
