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:

看到https://www.baeldung.com/spring-http-logging custom-request-logging

(如果答案得到需求/达到50+赞，我可以在这里添加准确的代码示例)

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。

如果你想详细阅读，请通读这个。 http://docs.spring.io/spring/docs/current/spring-framework-reference/html/aop.html

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";
        }
    }

}

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();
}

}

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

  private boolean includeResponsePayload = true;
  private int maxPayloadLength = 1000;

  private String getContentAsString(byte[] buf, int maxLength, String charsetName) {
    if (buf == null || buf.length == 0) return "";
    int length = Math.min(buf.length, this.maxPayloadLength);
    try {
      return new String(buf, 0, length, charsetName);
    } catch (UnsupportedEncodingException ex) {
      return "Unsupported Encoding";
    }

  @Override

    StringBuffer reqInfo = new StringBuffer()
     .append("[")
     .append(startTime % 10000)  // request ID

    String queryString = request.getQueryString();
    if (queryString != null) {

    }

    wrappedResponse.copyBodyToResponse();  // IMPORTANT: copy content of response back into original response

  }


}

我在应用程序中定义了日志级别。属性在日志文件中打印请求/响应、方法url

logging.level.org.springframework.web=DEBUG
logging.level.org.hibernate.SQL=INFO
logging.file=D:/log/myapp.log

我用的是Spring Boot。
