Spring Boot -如何记录所有的请求和响应与异常在单一的地方?

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。

目前Spring Boot拥有用于获取请求和响应日志的执行器特性。

但是您也可以使用Aspect(AOP)获取日志。

Aspect为您提供了诸如:@Before， @AfterReturning， @ afterthrows等注释。

@Before记录请求，@AfterReturning记录响应，@ afterthrows记录错误消息，您可能不需要所有端点的日志，因此可以对包应用一些筛选器。

下面是一些例子:

请求:

@Before("within(your.package.where.endpoints.are..*)")
    public void endpointBefore(JoinPoint p) {
        if (log.isTraceEnabled()) {
            log.trace(p.getTarget().getClass().getSimpleName() + " " + p.getSignature().getName() + " START");
            Object[] signatureArgs = p.getArgs();


            ObjectMapper mapper = new ObjectMapper();
            mapper.enable(SerializationFeature.INDENT_OUTPUT);
            try {

                if (signatureArgs[0] != null) {
                    log.trace("\nRequest object: \n" + mapper.writeValueAsString(signatureArgs[0]));
                }
            } catch (JsonProcessingException e) {
            }
        }
    }

Here @Before("within(your.package.where.endpoint .are. *)")有包的路径。这个包中的所有端点都将生成日志。

响应:

@AfterReturning(value = ("within(your.package.where.endpoints.are..*)"),
            returning = "returnValue")
    public void endpointAfterReturning(JoinPoint p, Object returnValue) {
        if (log.isTraceEnabled()) {
            ObjectMapper mapper = new ObjectMapper();
            mapper.enable(SerializationFeature.INDENT_OUTPUT);
            try {
                log.trace("\nResponse object: \n" + mapper.writeValueAsString(returnValue));
            } catch (JsonProcessingException e) {
                System.out.println(e.getMessage());
            }
            log.trace(p.getTarget().getClass().getSimpleName() + " " + p.getSignature().getName() + " END");
        }
    }

这里@AfterReturning("within(your.package.where.endpoint .are. *)")有包的路径。这个包中的所有端点都将生成日志。对象returnValue也包含响应。

例外:

@AfterThrowing(pointcut = ("within(your.package.where.endpoints.are..*)"), throwing = "e")
public void endpointAfterThrowing(JoinPoint p, Exception e) throws DmoneyException {
    if (log.isTraceEnabled()) {
        System.out.println(e.getMessage());

        e.printStackTrace();


        log.error(p.getTarget().getClass().getSimpleName() + " " + p.getSignature().getName() + " " + e.getMessage());
    }
}

这里@ afterthrows (pointcut = ("within(your.package.where.endpoint .are..*)")， throws = "e")有包的路径。这个包中的所有端点都将生成日志。Exception包含错误响应。

以下是完整的代码:

import com.fasterxml.jackson.core.JsonProcessingException;
import com.fasterxml.jackson.databind.ObjectMapper;
import com.fasterxml.jackson.databind.SerializationFeature;
import org.apache.log4j.Logger;
import org.aspectj.lang.JoinPoint;
import org.aspectj.lang.annotation.AfterReturning;
import org.aspectj.lang.annotation.AfterThrowing;
import org.aspectj.lang.annotation.Aspect;
import org.aspectj.lang.annotation.Before;
import org.springframework.core.annotation.Order;
import org.springframework.stereotype.Component;

@Aspect
@Order(1)
@Component
@ConditionalOnExpression("${endpoint.aspect.enabled:true}")
public class EndpointAspect {
    static Logger log = Logger.getLogger(EndpointAspect.class);

    @Before("within(your.package.where.is.endpoint..*)")
    public void endpointBefore(JoinPoint p) {
        if (log.isTraceEnabled()) {
            log.trace(p.getTarget().getClass().getSimpleName() + " " + p.getSignature().getName() + " START");
            Object[] signatureArgs = p.getArgs();


            ObjectMapper mapper = new ObjectMapper();
            mapper.enable(SerializationFeature.INDENT_OUTPUT);
            try {

                if (signatureArgs[0] != null) {
                    log.trace("\nRequest object: \n" + mapper.writeValueAsString(signatureArgs[0]));
                }
            } catch (JsonProcessingException e) {
            }
        }
    }

    @AfterReturning(value = ("within(your.package.where.is.endpoint..*)"),
            returning = "returnValue")
    public void endpointAfterReturning(JoinPoint p, Object returnValue) {
        if (log.isTraceEnabled()) {
            ObjectMapper mapper = new ObjectMapper();
            mapper.enable(SerializationFeature.INDENT_OUTPUT);
            try {
                log.trace("\nResponse object: \n" + mapper.writeValueAsString(returnValue));
            } catch (JsonProcessingException e) {
                System.out.println(e.getMessage());
            }
            log.trace(p.getTarget().getClass().getSimpleName() + " " + p.getSignature().getName() + " END");
        }
    }


    @AfterThrowing(pointcut = ("within(your.package.where.is.endpoint..*)"), throwing = "e")
    public void endpointAfterThrowing(JoinPoint p, Exception e) throws Exception {
        if (log.isTraceEnabled()) {
            System.out.println(e.getMessage());

            e.printStackTrace();


            log.error(p.getTarget().getClass().getSimpleName() + " " + p.getSignature().getName() + " " + e.getMessage());
        }
    }
}

在这里，使用@ConditionalOnExpression("${endpoint.aspect.enabled:true}")可以启用/禁用日志。只需添加endpoint.aspect。Enabled:true进入应用程序。属性并控制日志

其他回答

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

@hahn的回答需要一些修改才能为我工作，但这是迄今为止我能得到的最可定制的东西。

它对我不起作用，可能是因为我也有一个HandlerInterceptorAdapter[?? ?但是我一直从那个版本的服务器得到不好的响应。这是我对它的修改。

public class LoggableDispatcherServlet extends DispatcherServlet {

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

    @Override
    protected void doDispatch(HttpServletRequest request, HttpServletResponse response) throws Exception {

        long startTime = System.currentTimeMillis();
        try {
            super.doDispatch(request, response);
        } finally {
            log(new ContentCachingRequestWrapper(request), new ContentCachingResponseWrapper(response),
                    System.currentTimeMillis() - startTime);
        }
    }

    private void log(HttpServletRequest requestToCache, HttpServletResponse responseToCache, long timeTaken) {
        int status = responseToCache.getStatus();
        JsonObject jsonObject = new JsonObject();
        jsonObject.addProperty("httpStatus", status);
        jsonObject.addProperty("path", requestToCache.getRequestURI());
        jsonObject.addProperty("httpMethod", requestToCache.getMethod());
        jsonObject.addProperty("timeTakenMs", timeTaken);
        jsonObject.addProperty("clientIP", requestToCache.getRemoteAddr());
        if (status > 299) {
            String requestBody = null;
            try {
                requestBody = requestToCache.getReader().lines().collect(Collectors.joining(System.lineSeparator()));
            } catch (IOException e) {
                e.printStackTrace();
            }
            jsonObject.addProperty("requestBody", requestBody);
            jsonObject.addProperty("requestParams", requestToCache.getQueryString());
            jsonObject.addProperty("tokenExpiringHeader",
                    responseToCache.getHeader(ResponseHeaderModifierInterceptor.HEADER_TOKEN_EXPIRING));
        }
        logger.info(jsonObject);
    }
}

日志请求+自定义格式的有效载荷:

对于自定义格式，只需覆盖Spring日志记录器Bean的超级实现

假设我们希望跳过GET请求，只跟踪INFO日志级别的写请求(PUT, PATCH, DELETE等):

@Bean
public CommonsRequestLoggingFilter requestLoggingFilter() {
CommonsRequestLoggingFilter logFilter = new CommonsRequestLoggingFilter() {

  @Override
  protected boolean shouldLog(HttpServletRequest request) {
    return logger.isInfoEnabled() && !Objects.equals(request.getMethod(), "GET");
  }


  @Override
  protected void beforeRequest(HttpServletRequest request, String message) {
    // Do nothing if you need logging payload.
    // As, Before the Request, the payload is not read from the input-stream, yet.
  }


  @Override
  protected void afterRequest(HttpServletRequest request, String message) {
    logger.info(message); // Or log to a file here, as OP asks.
  }


  @Override
  protected @NonNull String createMessage(HttpServletRequest request, @NonNull String prefix, @NonNull String suffix) {
    // Output: [PUT][/api/my-entity], user:[my-loging], payload was:[{ "id": 33, "value": 777.00}]
    StringBuilder msg = new StringBuilder()
        .append(prefix)
        .append("[").append(request.getMethod()).append("]")
        .append("[").append(request.getRequestURI()).append("]");

    String user = request.getRemoteUser();
    msg.append(", user:[").append(null == user ? "" : user).append("]");

    String payload = getMessagePayload(request);
    if (payload != null) {
      // It's not null on After event. As, on Before event, the Input stream was not read, yet.
      msg.append(", payload was:[").append(payload.replace("\n", "")).append("]");  // Remove /n to be compliant with elastic search readers.
    }

    msg.append(suffix);
    return msg.toString();
  }
};
logFilter.setBeforeMessagePrefix("Incoming REST call: -->>>[");
logFilter.setBeforeMessageSuffix("]...");
logFilter.setAfterMessagePrefix("REST call processed: -<<<[");
logFilter.setAfterMessageSuffix("]");
logFilter.setIncludePayload(true);
logFilter.setMaxPayloadLength(64000);
return logFilter;
}

我在应用程序中定义了日志级别。属性在日志文件中打印请求/响应、方法url

logging.level.org.springframework.web=DEBUG
logging.level.org.hibernate.SQL=INFO
logging.file=D:/log/myapp.log

我用的是Spring Boot。
