Post请求RequestBody是空问题

3

为了在一个地方记录请求、响应、响应时间等，在拦截器的preHandle方法中读取了一遍HttpServletRequest，导致在controller读取到的RequestBody是空的。@RequestBody的required默认是true，导致抛出以下异常。 HttpServletRequest的流只能读取一次，当前还未找到好的解决办法。 `2018-10-25 21:59:14.712 [http-bio-8080-exec-8] ERROR c.f.s.r.c.e.GlobalExceptionHandler: - systemErrorHandler error, URI: /user/edit org.springframework.http.converter.HttpMessageNotReadableException: Required request body is missing: public com.flyer.springmvc.rest.common.BaseResponse com.flyer.springmvc.rest.web.UserController.editUser(com.flyer.springmvc.rest.web.req.SaveOrUpdateUser,org.springframework.validation.BindingResult) at org.springframework.web.servlet.mvc.method.annotation.RequestResponseBodyMethodProcessor.readWithMessageConverters(RequestResponseBodyMethodProcessor.java:154) ~[spring-webmvc-4.3.18.RELEASE.jar:4.3.18.RELEASE] at org.springframework.web.servlet.mvc.method.annotation.RequestResponseBodyMethodProcessor.resolveArgument(RequestResponseBodyMethodProcessor.java:128) ~[spring-webmvc-4.3.18.RELEASE.jar:4.3.18.RELEASE] at org.springframework.web.method.support.HandlerMethodArgumentResolverComposite.resolveArgument(HandlerMethodArgumentResolverComposite.java:121) ~[spring-web-4.3.18.RELEASE.jar:4.3.18.RELEASE]...
