May be problem with servelet api dependcy: use this in your maven pom for exemple: servelet api 依赖性可能有问题：例如，在您的 maven pom 中使用它：

   <!-- servlet api 3 -->
    <dependency>
        <groupId>javax.servlet</groupId>
        <artifactId>javax.servlet-api</artifactId>
        <version>3.0.1</version>
    </dependency>

Its seems a java version issue.它似乎是一个 java 版本问题。 compile the code with supporting jar(java version) only仅使用支持的 jar（java 版本）编译代码
