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

/**

 * There is also {@link org.springframework.web.filter.CommonsRequestLoggingFilter}  but it cannot log request method
 * And it cannot easily be extended.

After adding Actuators to the spring boot bassed application you have /trace endpoint available with latest requests informations. This endpoint is working based on TraceRepository and default implementation is InMemoryTraceRepository that saves last 100 calls. You can change this by implementing this interface by yourself and make it available as a Spring bean. For example to log all requests to log (and still use default implementation as a basic storage for serving info on /trace endpoint) I'm using this kind of implementation:

import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.boot.actuate.trace.InMemoryTraceRepository;
import org.springframework.boot.actuate.trace.Trace;
import org.springframework.boot.actuate.trace.TraceRepository;
import org.springframework.stereotype.Component;

import java.util.List;
import java.util.Map;


@Component
public class LoggingTraceRepository implements TraceRepository {

  private static final Logger LOG = LoggerFactory.getLogger(LoggingTraceRepository.class);
  private final TraceRepository delegate = new InMemoryTraceRepository();

  @Override
  public List<Trace> findAll() {
    return delegate.findAll();
  }

  @Override
  public void add(Map<String, Object> traceInfo) {
    LOG.info(traceInfo.toString());
    this.delegate.add(traceInfo);
  }
}

这个traceInfo映射以这种形式包含了请求和响应的基本信息: {method=GET, path=/api/hello/John, headers={request={host=localhost:8080, user-agent=curl/7.51.0, accept=*/*}， response={X-Application-Context=application, Content-Type=text/plain;charset=UTF-8, Content-Length=10, Date=Wed, 29 Mar 2017 20:41:21 GMT, status=200}}}。这里没有响应内容。

编辑!测井POST数据

你可以通过覆盖WebRequestTraceFilter来访问POST数据，但不认为这是一个好主意(例如，所有上传的文件内容都会去日志) 下面是示例代码，但不要使用它:

package info.fingo.nuntius.acuate.trace;

import org.apache.commons.io.IOUtils;
import org.springframework.boot.actuate.trace.TraceProperties;
import org.springframework.boot.actuate.trace.TraceRepository;
import org.springframework.boot.actuate.trace.WebRequestTraceFilter;
import org.springframework.stereotype.Component;

import javax.servlet.ServletException;
import javax.servlet.http.HttpServletRequest;
import java.io.IOException;
import java.nio.charset.Charset;
import java.util.LinkedHashMap;
import java.util.Map;

@Component
public class CustomWebTraceFilter extends WebRequestTraceFilter {

  public CustomWebTraceFilter(TraceRepository repository, TraceProperties properties) {
    super(repository, properties);
}

  @Override
  protected Map<String, Object> getTrace(HttpServletRequest request) {
    Map<String, Object> trace = super.getTrace(request);
    String multipartHeader = request.getHeader("content-type");
    if (multipartHeader != null && multipartHeader.startsWith("multipart/form-data")) {
        Map<String, Object> parts = new LinkedHashMap<>();
        try {
            request.getParts().forEach(
                    part -> {
                        try {
                            parts.put(part.getName(), IOUtils.toString(part.getInputStream(), Charset.forName("UTF-8")));
                        } catch (IOException e) {
                            e.printStackTrace();
                        }
                    }
            );
        } catch (IOException | ServletException e) {
            e.printStackTrace();
        }
        if (!parts.isEmpty()) {
            trace.put("multipart-content-map", parts);
        }
    }
    return trace;
  }
}

为了只记录结果为400的请求:

import org.springframework.web.util.WebUtils;

/**

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。
