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

自从最初的问题发布以来,执行器HTTP跟踪是否有任何发展,即有一种方法来丰富它与响应体?

用来自MDC、Spring-Sleuth或Zipkin的自定义元数据(如traceId和spanId)来丰富它怎么样?

同样对我来说,执行器HTTP跟踪不工作Spring Boot 2.2.3,我在这里找到了修复:https://juplo.de/actuator-httptrace-does-not-work-with-spring-boot-2-2/

pom.xml

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

application.properties

management.endpoints.web.exposure.include=httptrace

解决办法:

解决这个问题的简单方法是添加一个@Bean类型 InMemoryHttpTraceRepository到你的@Configuration-class:

@Bean
public HttpTraceRepository htttpTraceRepository()
{
  return new InMemoryHttpTraceRepository();
}

解释:

The cause of this problem is not a bug, but a legitimate change in the default configuration. Unfortunately, this change is not noted in the according section of the documentation. Instead it is burried in the Upgrade Notes for Spring Boot 2.2 The default-implementation stores the captured data in memory. Hence, it consumes much memory, without the user knowing, or even worse: needing it. This is especially undesirable in cluster environments, where memory is a precious good. And remember: Spring Boot was invented to simplify cluster deployments! That is, why this feature is now turned of by default and has to be turned on by the user explicitly, if needed.

其他回答

如果你在你的引导应用程序中使用Tomcat,这里是org.apache.catalina.filters.RequestDumperFilter的类路径。(但它不会为你提供“单一位置的例外”)。

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";
        }
    }

}

如前所述,Logbook非常适合于此,但在使用Java模块时,由于在Logbook -api和Logbook -core之间有一个分离包,因此在设置它时遇到了一些麻烦。

对于我的Gradle + Spring Boot项目,我需要

build.gradle

dependencies {
    compileOnly group: 'org.zalando', name: 'logbook-api', version: '2.4.1'
    runtimeOnly group: 'org.zalando', name: 'logbook-spring-boot-starter', version: '2.4.1'
    //...
}

logback-spring.xml

<configuration>
    <!-- HTTP Requests and Responses -->
    <logger name="org.zalando.logbook" level="trace" />
</configuration>

为了只记录结果为400的请求:

import javax.servlet.FilterChain;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import javax.servlet.http.HttpSession;

您可以在Spring Boot中使用驱动器。 它记录请求和响应以及有关servlet和系统操作的更多信息。 如果需要记录更多细节,只需将其添加为项目和配置的依赖项。 看看这个例子: Spring Boot示例中的执行器
