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

}

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。

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

下面粘贴的代码与我的测试一起工作，可以从我的[github项目][1]下载，在应用一个基于生产项目的解决方案后共享。

@Configuration
public class LoggingFilter extends GenericFilterBean {

    /**
     * It's important that you actually register your filter this way rather then just annotating it
     * as @Component as you need to be able to set for which "DispatcherType"s to enable the filter
     * (see point *1*)
     * 
     * @return
     */
    @Bean
    public FilterRegistrationBean<LoggingFilter> initFilter() {
        FilterRegistrationBean<LoggingFilter> registrationBean = new FilterRegistrationBean<>();
        registrationBean.setFilter(new LoggingFilter());

        // *1* make sure you sett all dispatcher types if you want the filter to log upon
        registrationBean.setDispatcherTypes(EnumSet.allOf(DispatcherType.class));

        // *2* this should put your filter above any other filter
        registrationBean.setOrder(Ordered.HIGHEST_PRECEDENCE);

        return registrationBean;
    }

    @Override
    public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain)
            throws IOException, ServletException {

        ContentCachingRequestWrapper wreq = 
            new ContentCachingRequestWrapper(
                (HttpServletRequest) request);

        ContentCachingResponseWrapper wres = 
            new ContentCachingResponseWrapper(
                (HttpServletResponse) response);

        try {

            // let it be ...
            chain.doFilter(wreq, wres);

            // makes sure that the input is read (e.g. in 404 it may not be)
            while (wreq.getInputStream().read() >= 0);

            System.out.printf("=== REQUEST%n%s%n=== end request%n",
                    new String(wreq.getContentAsByteArray()));

            // Do whatever logging you wish here, in this case I'm writing request 
            // and response to system out which is probably not what you wish to do
            System.out.printf("=== RESPONSE%n%s%n=== end response%n",
                    new String(wres.getContentAsByteArray()));

            // this is specific of the "ContentCachingResponseWrapper" we are relying on, 
            // make sure you call it after you read the content from the response
            wres.copyBodyToResponse();

            // One more point, in case of redirect this will be called twice! beware to handle that
            // somewhat

        } catch (Throwable t) {
            // Do whatever logging you whish here, too
            // here you should also be logging the error!!!
            throw t;
        }

    }
}

Spring已经提供了一个过滤器来完成这项工作。将以下bean添加到配置中

@Bean
public CommonsRequestLoggingFilter requestLoggingFilter() {
    CommonsRequestLoggingFilter loggingFilter = new CommonsRequestLoggingFilter();
    loggingFilter.setIncludeClientInfo(true);
    loggingFilter.setIncludeQueryString(true);
    loggingFilter.setIncludePayload(true);
    loggingFilter.setMaxPayloadLength(64000);
    return loggingFilter;
}

不要忘记将org.springframework.web.filter.CommonsRequestLoggingFilter的日志级别更改为DEBUG。
