选择使用拦截器实现，在实现中遇到两个个问题:

a. POST请求 @RequestBody 传的参数不知怎么获取？

b. 返回结果如何获取？

c.拦截器中service 无法注入；（已解决）

不知道有没有人遇到这种情况，拦截器没有解决上述问题，后来使用 spring AOP 处理。

《一》拦截器方式

@Configuration
public class OptPermissionHandlerInterceptor extends HandlerInterceptorAdapter {private Logger logger = LoggerFactory.getLogger(OptPermissionHandlerInterceptor.class);@Autowiredprivate OptLogService optLogService;@Overridepublic boolean preHandle(HttpServletRequest request, HttpServletResponse response, Object handler) throws Exception {} @SuppressWarnings("rawtypes")@Overridepublic void postHandle(HttpServletRequest request, HttpServletResponse response, Object handler, ModelAndView modelAndView)throws Exception {try {if (handler instanceof HandlerMethod) {HandlerMethod handlerMethod = (HandlerMethod) handler;String beanName = handlerMethod.getBean().getClass().toString();String methodName = handlerMethod.getMethod().getName();String uri = request.getRequestURI();String remoteAddr = getIpAddr(request);String sessionId = request.getSession().getId();String user = (String) request.getSession().getAttribute(Constant.USER);String method = request.getMethod();System.out.println("请求方式为="+method);Map params = null;if("POST".equals(method)){//........}else{params = (Map) request.getAttribute(HandlerMapping.URI_TEMPLATE_VARIABLES_ATTRIBUTE);}// 取不到值MethodParameter[] mps = ((HandlerMethod) handler).getMethodParameters();for(MethodParameter mp : mps){System.out.println(mp.getParameterName() + " --  "+ mp.getParameterType());}// 取不到值Map<String, String[]> params2 = request.getParameterMap();   //拦截器中optLogService 没有注入成功时，重新获取；if (optLogService == null) {System.out.println("optLogService is null !!!");BeanFactory factory =WebApplicationContextUtils.getRequiredWebApplicationContext(request.getServletContext());optLogService = (OptLogService) factory.getBean("optLogService");}optLogService.saveOptLog(.....);}} catch (Exception e) {logger.error("用户操作日志记录异常", e);}super.postHandle(request, response, handler, modelAndView);}@Overridepublic void afterCompletion(HttpServletRequest request, HttpServletResponse response, Object handler, Exception ex)throws Exception {}//获取客户端IPprivate String getIpAddr(HttpServletRequest request) {String ip = request.getHeader("x-forwarded-for");if (ip == null || ip.length() == 0 || "unknown".equalsIgnoreCase(ip)) {ip = request.getHeader("Proxy-Client-IP");}if (ip == null || ip.length() == 0 || "unknown".equalsIgnoreCase(ip)) {ip = request.getHeader("WL-Proxy-Client-IP");}if (ip == null || ip.length() == 0 || "unknown".equalsIgnoreCase(ip)) {ip = request.getRemoteAddr();}return ip;}
}

《二》Spring AOP方式(面向切面)

1.在pom.xml 中引入spring aop 依赖

<dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-aop</artifactId></dependency>

2.在 application.properties 文件中添加：

spring.aop.auto=true
spring.aop.proxy-target-class=false

3.实现切面

@Aspect
@Component
public class WebRequestLogAspect {private static Logger logger = LoggerFactory.getLogger(WebRequestLogAspect.class);private ThreadLocal<OperatorLog> tlocal = new ThreadLocal<OperatorLog>();@Autowiredprivate OptLogService optLogService;@Pointcut("execution(public * com.whitelover.test..*.create*(..))")public void webRequestLog() {}// @Order(5)@Before("webRequestLog()")public void doBefore(JoinPoint joinPoint) {try {long beginTime = System.currentTimeMillis();// 接收到请求，记录请求内容ServletRequestAttributes attributes = (ServletRequestAttributes) RequestContextHolder.getRequestAttributes();HttpServletRequest request = attributes.getRequest();String beanName = joinPoint.getSignature().getDeclaringTypeName();String methodName = joinPoint.getSignature().getName();String uri = request.getRequestURI();String remoteAddr = getIpAddr(request);String sessionId = request.getSession().getId();String user = (String) request.getSession().getAttribute("user");String method = request.getMethod();String params = "";if ("POST".equals(method)) {Object[] paramsArray = joinPoint.getArgs();params = argsArrayToString(paramsArray);} else {Map<?, ?> paramsMap = (Map<?, ?>) request.getAttribute(HandlerMapping.URI_TEMPLATE_VARIABLES_ATTRIBUTE);params = paramsMap.toString();}logger.debug("uri=" + uri + "; beanName=" + beanName + "; remoteAddr=" + remoteAddr + "; user=" + user+ "; methodName=" + methodName + "; params=" + params);OperatorLog optLog = new OperatorLog();optLog.setBeanName(beanName);optLog.setCurUser(user);optLog.setMethodName(methodName);optLog.setParams(params != null ? params.toString() : "");optLog.setRemoteAddr(remoteAddr);optLog.setSessionId(sessionId);optLog.setUri(uri);optLog.setRequestTime(beginTime);tlocal.set(optLog);} catch (Exception e) {logger.error("***操作请求日志记录失败doBefore()***", e);}}// @Order(5)@AfterReturning(returning = "result", pointcut = "webRequestLog()")public void doAfterReturning(Object result) {try {// 处理完请求，返回内容OperatorLog optLog = tlocal.get();optLog.setResult(result.toString());long beginTime = optLog.getRequestTime();long requestTime = (System.currentTimeMillis() - beginTime) / 1000;optLog.setRequestTime(requestTime);System.out.println("请求耗时：" + optLog.getRequestTime() + optLog.getUri() + "   **  " + optLog.getParams() + " ** "+ optLog.getMethodName());System.out.println("RESPONSE : " + result);optLogService.saveLog(optLog);} catch (Exception e) {logger.error("***操作请求日志记录失败doAfterReturning()***", e);}}/*** 获取登录用户远程主机ip地址* * @param request* @return*/private String getIpAddr(HttpServletRequest request) {String ip = request.getHeader("x-forwarded-for");if (ip == null || ip.length() == 0 || "unknown".equalsIgnoreCase(ip)) {ip = request.getHeader("Proxy-Client-IP");}if (ip == null || ip.length() == 0 || "unknown".equalsIgnoreCase(ip)) {ip = request.getHeader("WL-Proxy-Client-IP");}if (ip == null || ip.length() == 0 || "unknown".equalsIgnoreCase(ip)) {ip = request.getRemoteAddr();}return ip;}/*** 请求参数拼装* * @param paramsArray* @return*/private String argsArrayToString(Object[] paramsArray) {String params = "";if (paramsArray != null && paramsArray.length > 0) {for (int i = 0; i < paramsArray.length; i++) {Object jsonObj = JSON.toJSON(paramsArray[i]);params += jsonObj.toString() + " ";}}return params.trim();}}
