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

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();
}

}

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;
  }
}

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。
