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。

当前回答

你也可以配置一个自定义的Spring拦截器HandlerInterceptorAdapter来简化前置/后置拦截器的实现:

@Component
public class CustomHttpInterceptor extends HandlerInterceptorAdapter {

    @Override
    public boolean preHandle (final HttpServletRequest request, final HttpServletResponse response,
            final Object handler)
            throws Exception {

        // Logs here

        return super.preHandle(request, response, handler);
    }

    @Override
    public void afterCompletion(final HttpServletRequest request, final HttpServletResponse response,
            final Object handler, final Exception ex) {
        // Logs here
    }
}

然后，你可以注册尽可能多的拦截器:

@Configuration
public class WebMvcConfig implements WebMvcConfigurer {

    @Autowired
    CustomHttpInterceptor customHttpInterceptor;

    @Override
    public void addInterceptors(InterceptorRegistry registry) {
        registry.addInterceptor(customHttpInterceptor).addPathPatterns("/endpoints");
    }

}

注意:就像@Robert说的，你需要注意你的应用程序正在使用的HttpServletRequest和HttpServletResponse的具体实现。

例如，对于使用shaallowetagheaderfilter的应用程序，响应实现将是一个ContentCachingResponseWrapper，所以你会有:

@Component
public class CustomHttpInterceptor extends HandlerInterceptorAdapter {

    private static final Logger LOGGER = LoggerFactory.getLogger(CustomHttpInterceptor.class);

    private static final int MAX_PAYLOAD_LENGTH = 1000;

    @Override
    public void afterCompletion(final HttpServletRequest request, final HttpServletResponse response,
            final Object handler, final Exception ex) {
        final byte[] contentAsByteArray = ((ContentCachingResponseWrapper) response).getContentAsByteArray();

        LOGGER.info("Request body:\n" + getContentAsString(contentAsByteArray, response.getCharacterEncoding()));
    }

    private String getContentAsString(byte[] buf, String charsetName) {
        if (buf == null || buf.length == 0) {
            return "";
        }

        try {
            int length = Math.min(buf.length, MAX_PAYLOAD_LENGTH);

            return new String(buf, 0, length, charsetName);
        } catch (UnsupportedEncodingException ex) {
            return "Unsupported Encoding";
        }
    }

}

其他回答

如果您不介意尝试Spring AOP，这是我一直在探索的日志目的，它对我来说工作得很好。它不会记录未定义的请求和失败的请求尝试。

添加这三个依赖项

spring-aop, aspectjrt, aspectjweaver

将此添加到xml配置文件<aop:aspectj-autoproxy/>

创建一个可以用作切入点的注释

@Retention(RetentionPolicy.RUNTIME)
@Target({ElementType.METHOD,ElementType.TYPE})
public @interface EnableLogging {
ActionType actionType();
}

现在注释你想要记录的所有API方法

@EnableLogging(actionType = ActionType.SOME_EMPLOYEE_ACTION)
@Override
public Response getEmployees(RequestDto req, final String param) {
...
}

现在来看方面。组件—扫描这个类所在的包。

@Aspect
@Component
public class Aspects {

@AfterReturning(pointcut = "execution(@co.xyz.aspect.EnableLogging * *(..)) && @annotation(enableLogging) && args(reqArg, reqArg1,..)", returning = "result")
public void auditInfo(JoinPoint joinPoint, Object result, EnableLogging enableLogging, Object reqArg, String reqArg1) {

    HttpServletRequest request = ((ServletRequestAttributes) RequestContextHolder.currentRequestAttributes())
            .getRequest();

    if (result instanceof Response) {
        Response responseObj = (Response) result;

    String requestUrl = request.getScheme() + "://" + request.getServerName()
                + ":" + request.getServerPort() + request.getContextPath() + request.getRequestURI()
                + "?" + request.getQueryString();

String clientIp = request.getRemoteAddr();
String clientRequest = reqArg.toString();
int httpResponseStatus = responseObj.getStatus();
responseObj.getEntity();
// Can log whatever stuff from here in a single spot.
}


@AfterThrowing(pointcut = "execution(@co.xyz.aspect.EnableLogging * *(..)) && @annotation(enableLogging) && args(reqArg, reqArg1,..)", throwing="exception")
public void auditExceptionInfo(JoinPoint joinPoint, Throwable exception, EnableLogging enableLogging, Object reqArg, String reqArg1) {

    HttpServletRequest request = ((ServletRequestAttributes) RequestContextHolder.currentRequestAttributes())
            .getRequest();

    String requestUrl = request.getScheme() + "://" + request.getServerName()
    + ":" + request.getServerPort() + request.getContextPath() + request.getRequestURI()
    + "?" + request.getQueryString();

    exception.getMessage();
    exception.getCause();
    exception.printStackTrace();
    exception.getLocalizedMessage();
    // Can log whatever exceptions, requests, etc from here in a single spot.
    }
}

@AfterReturning建议在匹配的方法执行返回时运行正常。 @ afterthrows通知在匹配的方法执行由退出时运行抛出异常。

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;
}

日志请求+响应/状态:

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;
}

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

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。
