这个问题我找到解决方法了

但是还是不是很清楚具体的原因

就是在pom.xml文件中有依赖的<scope>要设置成provided

<dependency>
<groupId>javax.servlet</groupId> 
<artifactId>javax.servlet-api</artifactId> 
<version>3.1.0</version>
<scope>provided</scope>
</dependency> 
<dependency>
<groupId>javax</groupId>
<artifactId>javaee-api</artifactId>
<version>7.0</version>
<scope>provided</scope>
</dependency>
之后我还会查一下,,,,查到后会回答

还希望有吊大的告知一些原因........
