我不知道哪个方法抛出了这个错误，这个错误的原因是什么。实际上这个异常发生在我在tomcat中部署我的应用程序并尝试获取索引页面时(有时是第一次，有时是第二次，有时是第三次，无论何时到来。)，实际上根据我在ssl时的配置已启用，当我部署我的应用程序并尝试获取欢迎页面 session 过期页面时，从现在开始，一旦我尝试获取其他一些页面，它就会引发上述异常。我正在使用 spring 4、spring security、maven、hibernate 4。任何人都可以帮助我吗？任何帮助都将得到应用。

Answer 1

如果你有一个 SimpleMappingExceptionResolver 尝试检查你是否与你的 ControllerAdvice 注释类有冲突。异常只能在一个地方处理。

正如我所说，它可以由循环关系和 Jackason 作为序列化程序生成。在此您有一些选项，例如使用简化答案的 DTO 或用户 @JsonIgnore。
