struts2-core-*.jar您的WEB-INF/lib目录中似乎有多个副本.我想你应该只有一个.做一些清理工作.另请参阅您.classpath是否没有重复的条目.

这是一个罐子问题.你需要下载所有最新的struts jar.

尝试以下jar库:

  • 共同链12.jar
  • 共文件上传-1.3.1.jar
  • 公地IO-2.2.jar
  • 共享记录-API-1.1.jar

所有常见的jar(freemarker.jar,javaassist.jar,ognl.jar,xwork-core.jar,struts2-core.jar)都应该有最新版本.

特别要确保xwork和struts2核心罐具有相同的版本.Java 8之后,这些jar不再是可选的.
