本文详细介绍了Spring框架中一个关于Content-Type为null时报错的bug，该问题已在Spring 3.2.12版本中得到修复。文章提供了两种解决方案：一是给Content-Type赋值或设置为空字符串；二是升级Spring到最新版本。

https://jira.spring.io/browse/SPR-12173

spring bug

Content-Type为null时会报错，为空不会报错

spring自3.2.12已修复该bug

解决办法：

1/Content-Type 赋值或者给空字符串

2/升级spring

本次Ai大模型，我们选择清华大学出品的智谱AI大模型，为什么呢？因为chatgpt已经有开源第三方库，可以直接调，但是要科学上网（借助代理也是可是实现的）。只要是公司业务有这方面的需求。。。WebSocket：一种双向通信协议，同时支持服务端和客户端之间的实时交互。WebSocket 是基于 TCP 的长连接，和HTTP 协议相比，它能实现轻量级的、低延迟的数据传输，非常适合实时通信场景，主要用于交互性强的双向通信。SSE（Server-Sent Events）是一种基于 HTTP 协议的推送技术。

Invalid mime type “application/json； utf-8=“: ‘value‘ must not be empty解决方法

在HttpMessageConverterExtractor的getContentType方法中，可以看到。在getFirst方法中，是直接调用了headers.getFirst方法，headers的定义。那这样就可以找到解决的方法了，直接在请求的header中调用setContentType方法即可。这是一个很老的调用了，2018年的代码，忽然报这个错，很奇怪。网上找了一下，没找到有遇到这个问题的，就只能根据日志解决了。看源码可以看到是这个方法调用的时候出错。这样在调用的时候就可以直接取到了。
