org.springframework.http.converter.HttpMessageNotReadableException：缺少必需的请求正文：public org.springframework.http.ResponseEntity
org.springframework.http.converter.HttpMessageNotReadableException: Required request body is missing: public org.springframework.http.ResponseEntity
@RequestBody 用户用户
我有一个读取请求主体的拦截器，我看到 Http Servlet 请求在读取一次后从 POST 主体丢失参数。这里
它只能被读取一次
如何使所有请求（正文）都可缓存，以便可以使用 spring 引导多次读取它？

您不能多次读取请求，因为您加载了正文以便您可以使用它。另一种可能的解决方案是将此请求分解为两个单独的请求。第一个是拦截器，它会做一些事情，在这些事情之后，它会向第二个私有的 API 发送请求。
p.s。为什么需要先阅读请求？
