package javax.servlet.http does not exist

[zhonghuasheng]

jdk本身不带servlet.jar包,需要加载到环境变量中去,否则造成编译过不了.
Maven项目中直接添加dependency

    <dependency>
        <groupId>javax.servlet</groupId>
        <artifactId>javax.servlet-api</artifactId>
        <version>3.0.1</version>
        <scope>provided</scope>
    </dependency>

或者在classpath中追加*/tomcat8/lib/servlet-api.jar(tomcat8)
