我正在用spring boot开发REST API。我需要记录所有的请求与输入参数(与方法,例如。GET, POST等),请求路径,查询字符串,此请求对应的类方法,以及此操作的响应,包括成功和错误。例如:

成功的要求:

http://example.com/api/users/1

Log应该是这样的:

{
   HttpStatus: 200,
   path: "api/users/1",
   method: "GET",
   clientIp: "0.0.0.0",
   accessToken: "XHGu6as5dajshdgau6i6asdjhgjhg",
   method: "UsersController.getUser",
   arguments: {
     id: 1 
   },
   response: {
      user: {
        id: 1,
        username: "user123",
        email: "user123@example.com"   
      }
   },
   exceptions: []       
}

或请求错误:

http://example.com/api/users/9999

Log应该是这样的:

{
   HttpStatus: 404,
   errorCode: 101,                 
   path: "api/users/9999",
   method: "GET",
   clientIp: "0.0.0.0",
   accessToken: "XHGu6as5dajshdgau6i6asdjhgjhg",
   method: "UsersController.getUser",
   arguments: {
     id: 9999 
   },
   returns: {            
   },
   exceptions: [
     {
       exception: "UserNotFoundException",
       message: "User with id 9999 not found",
       exceptionId: "adhaskldjaso98d7324kjh989",
       stacktrace: ...................    
   ]       
}

我希望Request/Response是一个单独的实体,在成功和错误的情况下都具有与该实体相关的自定义信息。

春季实现这一目标的最佳做法是什么,可能是使用过滤器吗?如果是,能否提供具体的例子?

我使用过@ControllerAdvice和@ExceptionHandler,但正如我提到的,我需要在一个地方(和单个日志)处理所有成功和错误请求。


当前回答

这里是我的解决方案(Spring 2.0.x)

添加maven依赖:

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-actuator</artifactId>
</dependency>

编辑应用程序。属性,并添加以下行:

management.endpoints.web.exposure.include=* 

一旦你的spring boot应用程序启动,你可以通过调用这个url来跟踪最新的100个http请求: http://localhost:8070/actuator/httptrace

其他回答

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。

下面是我如何在春季数据休息 通过使用 org.springframework.web.util.ContentCachingRequestWrapper和 org.springframework.web.util.ContentCachingResponseWrapper

/**

    int length = Math.min(buf.length, this.maxPayloadLength);
    try {
      return new String(buf, 0, length, charsetName);
    } catch (UnsupportedEncodingException ex) {

    }

    wrappedResponse.copyBodyToResponse();  // IMPORTANT: copy content of response back into original response

  }


}

对上面提到的解决方案做了一些更改,如果记录器级别为info,请求和响应也将登录控制台和文件。我们可以在控制台或文件中打印。

如果您只看到请求有效负载的一部分,则需要调用setMaxPayloadLength函数,因为它默认只在请求正文中显示50个字符。另外,如果你不想记录你的认证头,设置setIncludeHeaders为false也是一个好主意!

@Bean
public CommonsRequestLoggingFilter requestLoggingFilter() {
    CommonsRequestLoggingFilter loggingFilter = new CommonsRequestLoggingFilter();
    loggingFilter.setIncludeClientInfo(false);
    loggingFilter.setIncludeQueryString(false);
    loggingFilter.setIncludePayload(true);
    loggingFilter.setIncludeHeaders(false);
    loggingFilter.setMaxPayloadLength(500);
    return loggingFilter;
}
