MappableContainerException 中包含的异常



嗨,我的网络服务代码中出现以下异常,任何人都可以对此提供帮助吗

Jun 28, 2012 8:49:46 PM com.sun.jersey.spi.container.ContainerResponse mapMappableContainerException  
SEVERE: The exception contained within MappableContainerException could not be mapped to a response, re-throwing to the HTTP container

看起来您在类路径上缺少某些内容。您需要修复的异常是来自 TenantConfigDB.getAllHotwords() 的 NoClassDefFoundException。MappableContainerException 只是一个包装器异常,如果底层代码抛出了一些不可映射到响应的内容(在本例中为 NoClassDefFoundException),Jersey 就会使用它。似乎无法加载DBManager类的某些依赖项,因为它不在类路径上。

我正在做一个调用 MQ 的 REST 服务,为我解决问题的是将.jar文件添加到 WEB-INF/lib 文件夹中

当您使用 new 启动对象并尝试打印或对其执行任何操作时,会发生这种情况。下面是引发堆栈溢出错误的示例:

JSONObject outerMostObj = new JSONObject();
outerMostObj.put("authFailure", outerMostObj);
System.out.println("Rretrun vaklueeee" + outerMostObj);

要解决 -> 您需要为对象分配适当的值并打印或执行任何您想要的操作。简单!:)

JSONObject outerMostObj = new JSONObject();
JSONObject outerMostObj = fetch.getJSONValue(); //added this one
outerMostObj.put("authFailure", outerMostObj);
System.out.println("Rretrun vaklueeee" + outerMostObj);
