【问题描述】：

@RequestBody 用户用户我有一个读取请求正文的拦截器，我看到 Http Servlet 请求在读取一次后从 POST 正文中丢失了参数。这里 Http Servlet request lose params from POST body after read it once 只能读一次如何使所有请求（正文）可缓存，以便使用spring boot可以多次读取？

标签： spring caching interceptor

【解决方案1】：

您不能多次读取请求，因为您加载了正文以便使用它。另一种可能的解决方案是将这个请求分成两个单独的请求。第一个是拦截器，它会做一些事情，在这些事情之后它将请求发送到第二个私有 API。
p.s.为什么你需要先阅读请求？
