pom.xml

推荐答案

您(您的Servlet容器)似乎正在尝试加载一些已经加载的类. servlet-api 和 el-api 应该由Servlet容器提供.

It seems like you (your Servlet container) are trying to load some classes that have already been loaded. The servlet-api and el-api should be provided by the Servlet container.

更改您的pom.xml以解决该问题

Change your pom.xml to account for that

<dependency>
    <groupId>javax</groupId>
    <artifactId>javaee-web-api</artifactId>
    <version>7.0</version>
    <scope>provided</scope>
</dependency>
