}

如果不需要记录已执行的java方法，则可以使用javax.servlet.Filter。

但是有了这个要求，您必须访问存储在DispatcherServlet的handlerMapping中的信息。也就是说，您可以重写DispatcherServlet来完成请求/响应对的日志记录。

下面是一个想法的例子，可以进一步加强和采用您的需要。

public class LoggableDispatcherServlet extends DispatcherServlet {

    private final Log logger = LogFactory.getLog(getClass());

    @Override
    protected void doDispatch(HttpServletRequest request, HttpServletResponse response) throws Exception {
        if (!(request instanceof ContentCachingRequestWrapper)) {
            request = new ContentCachingRequestWrapper(request);
        }
        if (!(response instanceof ContentCachingResponseWrapper)) {
            response = new ContentCachingResponseWrapper(response);
        }
        HandlerExecutionChain handler = getHandler(request);

        try {
            super.doDispatch(request, response);
        } finally {
            log(request, response, handler);
            updateResponse(response);
        }
    }

    private void log(HttpServletRequest requestToCache, HttpServletResponse responseToCache, HandlerExecutionChain handler) {
        LogMessage log = new LogMessage();
        log.setHttpStatus(responseToCache.getStatus());
        log.setHttpMethod(requestToCache.getMethod());
        log.setPath(requestToCache.getRequestURI());
        log.setClientIp(requestToCache.getRemoteAddr());
        log.setJavaMethod(handler.toString());
        log.setResponse(getResponsePayload(responseToCache));
        logger.info(log);
    }

    private String getResponsePayload(HttpServletResponse response) {
        ContentCachingResponseWrapper wrapper = WebUtils.getNativeResponse(response, ContentCachingResponseWrapper.class);
        if (wrapper != null) {

            byte[] buf = wrapper.getContentAsByteArray();
            if (buf.length > 0) {
                int length = Math.min(buf.length, 5120);
                try {
                    return new String(buf, 0, length, wrapper.getCharacterEncoding());
                }
                catch (UnsupportedEncodingException ex) {
                    // NOOP
                }
            }
        }
        return "[unknown]";
    }

    private void updateResponse(HttpServletResponse response) throws IOException {
        ContentCachingResponseWrapper responseWrapper =
            WebUtils.getNativeResponse(response, ContentCachingResponseWrapper.class);
        responseWrapper.copyBodyToResponse();
    }

}

HandlerExecutionChain—包含关于请求处理程序的信息。

然后你可以像下面这样注册这个dispatcher:

    @Bean
    public ServletRegistrationBean dispatcherRegistration() {
        return new ServletRegistrationBean(dispatcherServlet());
    }

    @Bean(name = DispatcherServletAutoConfiguration.DEFAULT_DISPATCHER_SERVLET_BEAN_NAME)
    public DispatcherServlet dispatcherServlet() {
        return new LoggableDispatcherServlet();
    }

下面是log的例子:

http http://localhost:8090/settings/test
i.g.m.s.s.LoggableDispatcherServlet      : LogMessage{httpStatus=500, path='/error', httpMethod='GET', clientIp='127.0.0.1', javaMethod='HandlerExecutionChain with handler [public org.springframework.http.ResponseEntity<java.util.Map<java.lang.String, java.lang.Object>> org.springframework.boot.autoconfigure.web.BasicErrorController.error(javax.servlet.http.HttpServletRequest)] and 3 interceptors', arguments=null, response='{"timestamp":1472475814077,"status":500,"error":"Internal Server Error","exception":"java.lang.RuntimeException","message":"org.springframework.web.util.NestedServletException: Request processing failed; nested exception is java.lang.RuntimeException","path":"/settings/test"}'}

http http://localhost:8090/settings/params
i.g.m.s.s.LoggableDispatcherServlet      : LogMessage{httpStatus=200, path='/settings/httpParams', httpMethod='GET', clientIp='127.0.0.1', javaMethod='HandlerExecutionChain with handler [public x.y.z.DTO x.y.z.Controller.params()] and 3 interceptors', arguments=null, response='{}'}

http http://localhost:8090/123
i.g.m.s.s.LoggableDispatcherServlet      : LogMessage{httpStatus=404, path='/error', httpMethod='GET', clientIp='127.0.0.1', javaMethod='HandlerExecutionChain with handler [public org.springframework.http.ResponseEntity<java.util.Map<java.lang.String, java.lang.Object>> org.springframework.boot.autoconfigure.web.BasicErrorController.error(javax.servlet.http.HttpServletRequest)] and 3 interceptors', arguments=null, response='{"timestamp":1472475840592,"status":404,"error":"Not Found","message":"Not Found","path":"/123"}'}

更新

如果出现错误，Spring会自动进行错误处理。因此，basicerrorcontroller# error被显示为请求处理程序。如果你想保留原始的请求处理程序，那么你可以在#processDispatchResult被调用之前在spring-webmvc- 4.5.release -sources.jar!/org/springframework/web/servlet/DispatcherServlet.java:971中覆盖这个行为来缓存原始的处理程序。

如果你已经配置了Spring引导配置服务器，那么只需要为类启用Debug记录器:

Http11InputBuffer.Http11InputBuffer.java

调试将记录每个请求的所有请求和响应

Note

 @Bean
public CommonsRequestLoggingFilter requestLoggingFilter() {
...
}

这种方法不适用于弹簧安全过滤器链。 你必须手动添加CommonsRequestLoggingFilter

protected void configure(HttpSecurity http) throws Exception {
         HttpSecurity filter = http
        .cors().and().addFilterBefore(new CommonsRequestLoggingFilter(), CorsFilter.class);
}

日志库是专门为记录HTTP请求和响应而设计的。它使用一个特殊的启动器库支持Spring Boot。

要在Spring Boot中启用日志，您所需要做的就是将库添加到项目的依赖项中。例如，假设您正在使用Maven:

<dependency>
    <groupId>org.zalando</groupId>
    <artifactId>logbook-spring-boot-starter</artifactId>
    <version>1.5.0</version>
</dependency>

默认情况下，日志输出如下所示:

{
  "origin" : "local",
  "correlation" : "52e19498-890c-4f75-a06c-06ddcf20836e",
  "status" : 200,
  "headers" : {
    "X-Application-Context" : [
      "application:8088"
    ],
    "Content-Type" : [
      "application/json;charset=UTF-8"
    ],
    "Transfer-Encoding" : [
      "chunked"
    ],
    "Date" : [
      "Sun, 24 Dec 2017 13:10:45 GMT"
    ]
  },
  "body" : {
    "thekey" : "some_example"
  },
  "duration" : 105,
  "protocol" : "HTTP/1.1",
  "type" : "response"
}

但是它不输出处理请求的类名。该库确实提供了一些用于编写自定义记录器的接口。

笔记

与此同时，库已经有了显著的发展，目前的版本是2.4.1，请参阅https://github.com/zalando/logbook/releases。例如，默认输出格式已经改变，可以配置，过滤等。

不要忘记将日志级别设置为TRACE，否则你将看不到任何东西:

logging:
  level:
    org.zalando.logbook: TRACE
