Here are the examples of the java api org.springframework.web.util.ContentCachingRequestWrapper taken from open source projects. HttpServletResponse wrapper that caches all content written to the output stream and writer , and allows this content to be retrieved via a byte array . Many gateway facilities have httptrace capabilities that help us centrally log request traffic. This method can be read multiple times. by AbstractRequestLoggingFilter.Note: As of Spring Framework 5.0, this wrapper is built on the Servlet 3.1 API. bodybodyContentCachingRequestWrapperbody .

See the following example: package com.example.testrest; import org.springframework.context.annotation.Bean; But since the output stream will also be consumed so you have to copy the response back to the output stream using wrapper.copyBodyToResponse(). The main issue with reading request is that as soon as the input stream is consumed its gone whoof and cannot be read again. If other filters apply a ContentCachingRequestWrapper and/or a ContentCachingResponseWrapper before, our filters are simply going to use those instead of re-applying another layer of content caching. qq_27502511 2022-11-02 15:51:07 . Pros in that its easy to integrate and almost development free; Cons in that it doesnt log many dimensions and you need to build a facility to cache and consume these log messages. length = Math.min(buf.length, getRequestMaxPayloadLength()); String(responseWrapper.getContentAsByteArray()); Creating JSON documents from java classes using gson. a API. 2 comments brucelwl commented on Apr 27 ContentCachingRequestWrapper#getContentAsByteArray is empty before javax.servlet.FilterChain#doFilter spring-projects-issues added the status: waiting-for-triage label on Apr 27 Sign up for free to join this conversation on GitHub .

String(((ContentCachingRequestWrapper) request). What is more, when I check size of request earlier - it is correct. Summary In this tutorial, we've looked at how we can read the request body multiple times using Spring MVC. log request body string before RestController's methods enter. z Spring Boot, AbstractRequestLoggingFilter CommonsRequestLoggingFilter . libi In order to polish the data about requests and responses, we will implement a filter that will extend the OncePerRequestFilter.java class Let's call this our movie LoggingFilter and start writing it. public byte [] getContentAsByteArray () Return the cached request content as a byte array. libx lib3 sources / libspring-java / 4.3.22-4 / spring-web / src / main / java / org / springframework / web / util / ContentCachingRequestWrapper.java, Browse by prefix: This filter will have precedence over the. org.springframework.beans.factory.annotation.Autowired, org.springframework.security.core.context.SecurityContext, org.springframework.security.core.context.SecurityContextHolder, org.springframework.web.filter.OncePerRequestFilter, org.springframework.web.util.ContentCachingRequestWrapper, org.springframework.web.util.ContentCachingResponseWrapper, com.fasterxml.jackson.core.JsonProcessingException, com.fasterxml.jackson.databind.ObjectMapper, com.fasterxml.jackson.databind.node.NullNode, "org/springframework/boot/logging/logback/base.xml", "ch.qos.logback.core.rolling.RollingFileAppender", "ch.qos.logback.core.rolling.TimeBasedRollingPolicy", "no-cache, no-store, max-age=0, must-revalidate", Qiita Advent Calendar 2022 :), You can efficiently read back useful information. j libv I once tried HandlerInterceptor but will . libj ContentCachingRequestWrapperinputStreamcachedContentinputStream, chain.doFilter(requestWrapper, response)requestWrapper.getContentAsByteArray . libu Note: The byte array returned from this method reflects the amount of content that has has been read at the time when it is called. I haven`t got any post limit in Tomcat. It will clear the cached content by invoking copyToResponse, which makes the filter who wraps the response with ContentCachingResponseWrapper loses the cached content in it. The following examples show how to use org.springframework.web.util.ContentCachingRequestWrapper . Solution 2. The Debsources developers. These classes can be utilized very effectively, for example, in the following little filter: - LoggingFilter.java This is based on the CommonsRequestLoggingFilter method of parsing requests. org.springframework.web.util.ContentCachingRequestWrapper org.springframework.web.util.ContentCachingResponseWrapper Springorg.springframework.web.util.ContentCachingRequestWrapper org.springframework.web.util.ContentCachingResponseWrapper Spring Start a free trial. Instead of writing your own classes for caching (which can be found at several places on web), Spring provides a couple of useful classes i.e. GETBody. o String raw = StreamUtils.copyToString(request.getInputStream(), charset); // if no content in raw inputStream, , try to read cached. . Not many dimensions are logged, but you can certainly try it if its enough. . There are several options to trace the incoming HTTP Requests of a Spring Boot 2.x application. Advantages are that httptrace logs can be managed centrally and development-free; Disadvantages are that they are technically demanding and require supporting distribution, storage, and query facilities. private void writeRequestParametersToCachedContent () getContentAsByteArray public byte [] getContentAsByteArray () Return the cached request content as a byte array. Instead of writing your own classes for caching (which can be found at several places on web), Spring provides a couple of useful classes . libo First, let's declare an instance of our logger. b Since the response was also wrapped before passing it to the filter chain, it will also be cached to the output stream as soon as it is written on its way back. *
