自己写的一个springmvc例子，tomcat启动报错，页面不能跳转，报500错误

这是控制台输出的错误

严重: StandardWrapper.Throwable
org.springframework.beans.factory.BeanDefinitionStoreException: Failed to read candidate component class: file [D:\Develop\workplace.metadata.plugins\org.eclipse.wst.server.core\tmp1\wtpwebapps\springmvc_1\WEB-INF\classes\com\zbw\springmvc\Handler\HelloWord.class]; nested exception is org.springframework.core.NestedIOException: ASM ClassReader failed to parse class file - probably due to a new Java class file version that isn't supported yet: file [D:\Develop\workplace.metadata.plugins\org.eclipse.wst.server.core\tmp1\wtpwebapps\springmvc_1\WEB-INF\classes\com\zbw\springmvc\Handler\HelloWord.class]; nested exception is java.lang.IllegalArgumentException
