Question

我正在尝试在我的项目中将DynamicJasper报告与Struts2集成。 Strut2（使用XWork 2.2.1 jar）已经在使用JasperReports（版本4.7.1）。根据{{3}}我添加了DynamicJasper（版本5.0.0），对于Struts 2集成，将依赖关系DynamicJasper-Struts2（版本1.3）添加到最新版本。

执行期间抛出以下错误

org.apache.catalina.core.StandardWrapperValve invoke

在浏览时，我遇到了这个功能请求Struts 2.1.6兼容性（official dynamic jasper reports documention）已经关闭，我相信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那个版本。

为了更清晰，以下是我的代码和依赖关系：

Answer 1

ActionContext类具有方法签名

public Object get(String key)

所以这是异常的原因，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。您的maven依赖项也应该与Struts 2框架的具体版本相对应。请参阅我对Conflicts in xwork and xwork-core的回答。
