Answer 1

看起来你在类路径上遗漏了一些东西。您需要修复的例外是来自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能映射到响应的东西（在这种情况下它是NoClassDefFoundException）。似乎DBManager类的某些依赖项无法加载，因为它不在类路径上。

Answer 2

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。下面是抛出堆栈溢出错误的示例：

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

解决 - ＆gt;您需要为对象指定适当的值并打印或执行您想要的任何操作。简单！：）

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