java - 异常启动过滤器struts2 :NoSuchMethodError

Question

我正在尝试在 jboss 服务器上部署 Struts2 应用程序，但收到 NoSuchMethodException。但是，我已经包含了 xwork2-core-2.3.14 jar，其中包含异常中提到的 UrlSet 方法。我无法认识到出了什么问题。任何人都可以建议可能出了什么问题吗？

Answer 1

struts.jar
struts2-convention-plugin-2.1.6.jar
struts2-core-2.3.14.3.jar
struts2-json-plugin-2.1.8.1.jar
struts2-tiles-plugin-2.1.6.jar
xwork2.jar
xwork-core-2.3.14.jar

这已经超越了邪恶。所有资源必须对齐(相同版本)，并且可能由于安全问题而更新到最新版本。同时删除 struts.jar 和 xwork2.jar (!!)。

那么你需要

struts.jar
struts2-convention-plugin-2.3.16.3.jar
struts2-core-2.3.16.3.jar
struts2-json-plugin-2.3.16.3.jar
struts2-tiles-plugin-2.3.16.3.jar
xwork2.jar
xwork-core-2.3.16.3.jar

还要更新 ognl.jar 和 freemarker.jar，因为它们已经过时了:

• 最新ognl.jar ;
• 最新freemarker.jar .
