我在升级Spring版本（从3.2.6到4.2.1）时遇到一些问题。

尝试获取与登录页面相关的css和js文件时，出现500 Internal server
error。在服务器端，我看到异常：’java.lang.IllegalArgumentException：[0]没有匹配的常量”

调试之后，我看到在’ResourceHttpRequestHandler.handleRequest（）’方法中，在将任何状态设置为响应之前，先检查响应状态-
导致’java.lang.IllegalArgumentException：[0]没有匹配的常量”异常。

检查在以下位置完成：“
ServletWebRequest.isCompatibleWithConditionalRequests（ServletWebRequest.java:244）”

在’ResourceHttpRequestHandler.handleRequest（ResourceHttpRequestHandler.java:240）中调用

当状态更改阶段仅发生在’writeContent（response，resource）’ResourceHttpRequestHandler.java:271中。

我找到了一种解决方法-使用自定义“ ResourceHttpRequestHandler”在响应状态为0之前将响应状态设置为200，然后再处理请求。

知道如何以更清洁的方式修复它吗？还是一个错误？

堆栈跟踪：
