我不知道哪个方法会抛出此错误，导致此错误的原因是什么。实际上，当我在tomcat中部署我的应用程序并尝试获取索引页面时出现此异常（有时是第一次，有时是第二次，有时是第三次，无论什么时候它都会出现。），实际上根据我的配置时ssl已启用，当我部署我的应用程序并尝试获取欢迎页面会话过期页面被调用，从现在一旦我尝试获取其他一些页面，它会抛出上述异常。我正在使用弹簧4，弹簧安全，maven，冬眠4.任何人都可以帮助我吗？任何帮助都会得到满足。

Answer 1

如果您有SimpleMappingExceptionResolver，请尝试检查您是否与ControllerAdvice注释类发生冲突。例外情况只能在一个地方处理。

正如我所说，它可能是由一个周期性的关系和Jackason作为序列化器产生的。在这里你有一些选项，比如使用简化答案的DTO或用户@JsonIgnore。

我得到异常 - org.apache.catalina.core.ApplicationDispatcher.invoke抛出异常java.lang.IllegalStateException
