我正在用彈簧靴做休息api。我需要使用輸入?yún)?shù)（使用方法，例如GET，POST等），請(qǐng)求路徑，查詢字符串，此請(qǐng)求的相應(yīng)類方法，以及此操作的響應(yīng)（成功和錯(cuò)誤）來(lái)記錄所有請(qǐng)求。舉個(gè)例子：成功要求：http://example.com/api/users/1日志應(yīng)該看起來(lái)像這樣：{ 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: [] }或者請(qǐng)求錯(cuò)誤：http://example.com/api/users/9999日志應(yīng)該是這樣的： { 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: ................... ] }我希望請(qǐng)求/響應(yīng)成為單個(gè)實(shí)體，在成功和錯(cuò)誤情況下都包含與此實(shí)體相關(guān)的自定義信息。在春天實(shí)現(xiàn)這一目標(biāo)的最佳做法是什么，可能是過(guò)濾器？如果是的話，你能提供具體的例子嗎？（我已經(jīng)使用了@ControllerAdvice和@ExceptionHandler，但正如我所提到的，我需要在單個(gè)位置（和單個(gè)日志）處理所有成功和錯(cuò)誤請(qǐng)求）。

javax.servlet.Filter如果沒(méi)有要求記錄已執(zhí)行的java方法，則可以使用。
但是有了這個(gè)要求，你必須訪問(wèn)存儲(chǔ)在其中handlerMapping的信息DispatcherServlet。也就是說(shuō)，您可以覆蓋DispatcherServlet以完成請(qǐng)求/響應(yīng)對(duì)的記錄。
以下是一個(gè)可以進(jìn)一步增強(qiáng)和滿足您需求的想法示例。
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 - 包含有關(guān)請(qǐng)求處理程序的信息。
然后，您可以將此調(diào)度程序注冊(cè)如下：
@Bean
public ServletRegistrationBean dispatcherRegistration() {
return new ServletRegistrationBean(dispatcherServlet());
}
@Bean(name = DispatcherServletAutoConfiguration.DEFAULT_DISPATCHER_SERVLET_BEAN_NAME)
public DispatcherServlet dispatcherServlet() {
return new LoggableDispatcherServlet();
}
這是日志的樣本：
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"}'}
UPDATE
如果出現(xiàn)錯(cuò)誤，Spring會(huì)自動(dòng)進(jìn)行錯(cuò)誤處理。因此，BasicErrorController#error顯示為請(qǐng)求處理程序。如果要保留原始請(qǐng)求處理程序，則可以在調(diào)用spring-webmvc-4.2.5.RELEASE-sources.jar!/org/springframework/web/servlet/DispatcherServlet.java:971之前覆蓋此行為#processDispatchResult，以緩存原始處理程序。

不要寫任何攔截器，濾波器，組件，方面等，這是一個(gè)非常常見(jiàn)的問(wèn)題，已經(jīng)解決了很多次。Spring Boot有一個(gè)名為Actuator的模塊，它提供開(kāi)箱即用的HTTP請(qǐng)求記錄。有一個(gè)端點(diǎn)映射到/trace（SB1.x）或/actuator/httptrace（SB2.0 +），它將顯示最近100個(gè)HTTP請(qǐng)求。您可以自定義它以記錄每個(gè)請(qǐng)求，或?qū)懭霐?shù)據(jù)庫(kù)。要獲得所需的端點(diǎn)，您需要執(zhí)行器springboot依賴項(xiàng)，并且還要“查找”您正在尋找的端點(diǎn)，并可能設(shè)置或禁用它的安全性。
此外，此應(yīng)用程序?qū)⒃诤翁庍\(yùn)行？你會(huì)使用PaaS嗎？例如，主機(jī)提供商Heroku提供請(qǐng)求記錄作為其服務(wù)的一部分，您無(wú)需進(jìn)行任何編碼。

Spring已經(jīng)提供了一個(gè)完成這項(xiàng)工作的過(guò)濾器。將以下bean添加到您的配置中
@Bean
public CommonsRequestLoggingFilter requestLoggingFilter() {
CommonsRequestLoggingFilter loggingFilter = new CommonsRequestLoggingFilter();
loggingFilter.setIncludeClientInfo(true);
loggingFilter.setIncludeQueryString(true);
loggingFilter.setIncludePayload(true);
return loggingFilter;
}
不要忘記將日志級(jí)別更改org.springframework.web.filter.CommonsRequestLoggingFilter為DEBUG。
