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。

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。

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);
}

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

我创建了一个名为LoggingConfig.java的文件，内容如下:

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.web.filter.CommonsRequestLoggingFilter;

@Configuration
public class LoggingConfig {

    @Bean
    public CommonsRequestLoggingFilter requestLoggingFilter() {
        final CommonsRequestLoggingFilter loggingFilter = new CommonsRequestLoggingFilter();
        loggingFilter.setIncludeClientInfo(true);
        loggingFilter.setIncludeQueryString(true);
        loggingFilter.setIncludePayload(true);
        loggingFilter.setMaxPayloadLength(32768);
        return loggingFilter;
    }
}

在应用程序中。我添加的属性:

logging.level.org.springframework.web.filter.CommonsRequestLoggingFilter=DEBUG

为了记录所有带有输入参数和主体的请求，我们可以使用过滤器和拦截器。但是在使用过滤器或拦截器时，我们不能多次打印请求体。更好的方法是使用spring-AOP。通过使用这个，我们可以将日志机制从应用程序中分离出来。AOP可用于记录应用程序中每个方法的输入和输出。

我的解决方案是:

 import org.aspectj.lang.ProceedingJoinPoint;
 import org.aspectj.lang.annotation.Around;
 import org.aspectj.lang.annotation.Aspect;
 import org.aspectj.lang.annotation.Pointcut;
 import org.aspectj.lang.reflect.CodeSignature;
 import org.slf4j.Logger;
 import org.slf4j.LoggerFactory;
 import org.springframework.stereotype.Component;
 import com.fasterxml.jackson.databind.ObjectMapper;
 @Aspect
 @Component
public class LoggingAdvice {
private static final Logger logger = 
LoggerFactory.getLogger(LoggingAdvice.class);

//here we can provide any methodName, packageName, className 
@Pointcut(value = "execution(* com.package.name.*.*.*(..) )")
public void myPointcut() {

}

@Around("myPointcut()")
public Object applicationLogger(ProceedingJoinPoint pjt) throws Throwable {
    ObjectMapper mapper = new ObjectMapper();
    String methodName = pjt.getSignature().getName();
    String className = pjt.getTarget().getClass().toString();
    String inputParams = this.getInputArgs(pjt ,mapper);
    logger.info("method invoked from " + className + " : " + methodName + "--Request Payload::::"+inputParams);
    Object object = pjt.proceed();
    try {
        logger.info("Response Object---" + mapper.writeValueAsString(object));
    } catch (Exception e) {
    }
    return object;
}

private String getInputArgs(ProceedingJoinPoint pjt,ObjectMapper mapper) {
    Object[] array = pjt.getArgs();
    CodeSignature signature = (CodeSignature) pjt.getSignature();

    StringBuilder sb = new StringBuilder();
    sb.append("{");
    int i = 0;
    String[] parameterNames = signature.getParameterNames();
    int maxArgs = parameterNames.length;
    for (String name : signature.getParameterNames()) {
        sb.append("[").append(name).append(":");
        try {
            sb.append(mapper.writeValueAsString(array[i])).append("]");
            if(i != maxArgs -1 ) {
                sb.append(",");
            }
        } catch (Exception e) {
            sb.append("],");
        }
        i++;
    }
    return sb.append("}").toString();
}

}
