在浏览时，我发现这个特性请求Struts 2.1.6兼容性（）已经关闭，我认为这是我的项目中的问题，它说

Xwork在版本2.1.2中更改了方法签名，我们重新编译了源代码 对于那个版本

为了更清晰，以下是我的代码和依赖项：

ActionContext
类具有方法签名

public Object get(String key)
因此，这就是异常的原因，您应该修改
ar.com.fdvs.dj.struts2.DJStruts2Result
以及可能使用
Object
类型参数的其他类，或者选择正确的版本。此外，您的maven依赖项应该对应于Struts 2框架的具体版本。查看我的答案。

请告诉我可以修改什么“ar.com.fdvs.dj.struts2.DJStruts2Result”。这是一个现有的struts 2项目，jasper报告已经就位并正在运行。此时，我不确定是否可以更改现有的xwork或Strutjar版本。是的，我可以修改jasper的版本。请建议..在
ar.com.fdvs.dj.struts2.DJStruts2Result
的源代码中查找该方法的引用，并替换错误的引用。非常感谢您提出修改
ar.com.fdvs.dj.struts2.DJStruts2Result
，它现在正在工作：）。我只是将
ar.com.fdvs.dj.struts2.DJStruts2Result
替换为
结果类型中全新的自定义类
com.orgn.appl.util.DJStruts2Result
，它扩展了我们的自定义类
com.orgn.appl.util.JasperReportsResult
，并解决了问题！！！
