Question

我遇到一个异常错误，只有在我的网络应用程序的任何页面上请求URL时才会在某些PC上发生。错误是：

净:: ERR-INVALID-CHUNKED编码

错误并不总是发生，但我可以说3个请求中的2个必然会出错。该应用程序是Spring MVC jar，它部署在Web服务器上。

请帮忙吗？

我的Java / Spring / Hibernate Web应用程序中有类似的问题。在Chrome浏览器和Postman客户端中可以看到它，但在Firefox中却没有（它似乎更容忍违反http规范）。

Rest API控制器必须响应一个JSON，其中包含来自数据库的实体列表。看来实体之间存在循环依赖。序列化此实体时，它导致StackOverflowError，进而在响应传输期间意外关闭了连接。这是从服务器端看的样子：

10:42:08.665 [http-nio-8080-exec-3] ERROR com.myproject.rest.common.GlobalErrorHandler - Error while performing REST call org.springframework.http.converter.HttpMessageNotWritableException: Could not write JSON: Infinite recursion (StackOverflowError); nested exception is com.fasterxml.jackson.databind.JsonMappingException: Infinite recursion (StackOverflowError) (through reference chain:
