我正在尝试将DynamicJasper报表与Struts2集成到我的项目中。 Strut2（带有XWork 2.2.1 jar）已经在使用JasperReports（版本4.7.1）。按照official dynamic jasper reports documention，我添加了DynamicJasper（版本5.0.0），对于Struts 2集成，添加了依赖项DynamicJasper-Struts2（版本1.3）为最新可用版本。
我在执行过程中抛出以下错误
org.apache.catalina.core.StandardWrapperValve invoke

在浏览时，我遇到了此功能请求Struts 2.1.6 Compatibility（http://sourceforge.net/p/dynamicjasper/feature-requests/4/）已关闭，我认为这是我项目中的问题，其中说
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
对于该版本。
为了更好的说明，这是我的代码和依赖关系，如下所示：

最佳答案
ActionContext类具有方法签名
public Object get(String key)
因此这是导致异常的原因，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选择正确的版本。您的Maven依赖项也应对应于Struts 2框架的具体版本。参见我对Conflicts in xwork and xwork-core的回答。
