网上找了很多方法，大都是说jdk版本有问题，但是我的情况是只有这一个项目出现这种问题，其他项目都是正常，所以排除这个原因，后来找公司大佬帮忙看了一下，才知道jar包冲突

解决方法：

将pom.xml文件中的

<dependency>
    <groupId>javax</groupId>
    <artifactId>javaee-api</artifactId>
    <version>6.0</version>
</dependency>

修改为

<dependency>
    <groupId>javax</groupId>
    <artifactId>javaee-api</artifactId>
    <version>6.0</version>
    <scope>provided</scope>
</dependency>
