# 日志拦截器方法 #

**方法一 .创建拦截器类（使用拦截器全局拦截所有请求）**

public class LogInterceptor implements HandlerInterceptor {
      private final Logger logger = LoggerFactory.getLogger(LogInterceptor.class);
      @Override
      public boolean preHandle(HttpServletRequest httpServletRequest, HttpServletResponse httpServletResponse, Object o) throws Exception {
        //把整个log中的参数，交给logUtil来获取，并返回log对象
        Log log = null;
        try {
          log = LoggerUtil.getLog(httpServletRequest);
        }catch (GeneralException g){
          logger.warn("logger",g.getMessage());
        }catch (Exception e){
          logger.error("logger",e.getMessage());
        }
        httpServletRequest.setAttribute(LoggerUtil.LOG_OPERATE,log);
        return true;
      }
    
      @Override
      public void postHandle(HttpServletRequest httpServletRequest, HttpServletResponse httpServletResponse, Object o, ModelAndView modelAndView) throws Exception {
    
      }
    
      @Override
      public void afterCompletion(HttpServletRequest httpServletRequest, HttpServletResponse httpServletResponse, Object o, Exception e) throws Exception {
        //返回视图时，插入操作日志
        LogMapper logMapper = getMapper(LogMapper.class,httpServletRequest);
        Log log = (Log) httpServletRequest.getAttribute(LoggerUtil.LOG_OPERATE);
        if(log == null){
          logger.warn("日志信息为空",log);
        }else{
          logMapper.insert(log);
        }
      }
      private <T> T getMapper(Class<T> clazz,HttpServletRequest request)
      {
        BeanFactory factory = WebApplicationContextUtils.getRequiredWebApplicationContext(request.getServletContext());
        return factory.getBean(clazz);
      }
    
    }

拦截器的执行顺序，这里不解释了。这里注意mapper类是如何创建的。   
**2. 注册拦截器**

@Configuration
    public class WebMvcConfig extends WebMvcConfigurerAdapter {
        @Override
        public void addInterceptors(InterceptorRegistry registry) {
            registry.addInterceptor(new UserInterceptor()).addPathPatterns("/**").excludePathPatterns("/user/login");
            registry.addInterceptor(new LogInterceptor()).addPathPatterns("/**");
            super.addInterceptors(registry);
        }
    }

1.  LoggerUtil类（保存数据入库使用）

public class LoggerUtil {
        public static final String LOG_TARGET_TYPE="targetType";
        public static final String LOG_ACTION="action";
        public static final String LOG_REMARK="remark";
        public LoggerUtil(){}
    
        public static Log getLog(HttpServletRequest request){
            //1.依次获取每个属性信息 userId,operator,action,remark,ip,targetType
            Log log = new Log();
            log.setIp(LoggerUtil.getCliectIp(request));
            log.setOperator("operator");
            log.setUserId(1);
            log.setAction("create");
            log.setCustomerId("0000-1111");
            log.setTargetType("message");
            log.setRemark("消息发布");
            return log;
        }
        /**
         * 获取客户端ip地址
         * @param request
         * @return
         */
        public static String getCliectIp(HttpServletRequest request){
            String ip = request.getHeader("X-Real-IP");
            if (!StringUtils.isBlank(ip) && !"unknown".equalsIgnoreCase(ip)) {
                return ip;
            }
            ip = request.getHeader("X-Forwarded-For");
            if (!StringUtils.isBlank(ip) && !"unknown".equalsIgnoreCase(ip)) {
                // 多次反向代理后会有多个IP值，第一个为真实IP。
                int index = ip.indexOf(',');
                if (index != -1) {
                    return ip.substring(0, index);
                } else {
                    return ip;
                }
            } else {
                return request.getRemoteAddr();
            }
        }
    
    }

*   
 *  loggerUtil类主要返回一个Log对象的实体类。

# 方法二   AOP记录操作日志 #

1.  引入springboot的aop的jar

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

1.  LogAopAction类

@Aspect
    @Component
    public class LogAopAction {
        private final Logger logger = LoggerFactory.getLogger(LogAopAction.class);
        @Autowired
        private OperatorLogService operatorLogService;
        @Autowired
        private OperationUserService userService;
    
        @Pointcut("@annotation(com.yitao.cms.config.aopLog.LogAnnotation)")//配置切点
        private void pointCutMethod() {
        }
    
        //around可获取请求和返回参数!
         @AfterReturning(value = "pointCutMethod()",returning = "rtv")  //执行后操作
        public void after(JoinPoint joinPoint, Object rtv) {
            // 接收到请求，记录请求内容
            ServletRequestAttributes attributes = (ServletRequestAttributes) RequestContextHolder.getRequestAttributes();
            HttpServletRequest request = attributes.getRequest();
            OperationUserCmsModel userSession = UserSession.getUserSession(request);
            if (userSession != null) {
                //获取请求参数
                String beanName = joinPoint.getSignature().getDeclaringTypeName();
                String methodName = joinPoint.getSignature().getName();
                String url = request.getRequestURI();
                String remoteAddr = getIpAddr(request);
                String requestMethod = request.getMethod();
                try {
                    String targetName = joinPoint.getTarget().getClass().getName();
                    Class targetClass = Class.forName(targetName);
                    Method[] methods = targetClass.getMethods();
                    OperatorLogDto optLog = new OperatorLogDto();
                    //请求参数
                    if (request.getParameterMap()!=null && request.getParameterMap().isEmpty()!=true) {//dan
                        optLog.setRequestPara(JSON.toJSONString(request.getParameterMap()));
                    }else {
                        Object[] object = joinPoint.getArgs();
                        if (object.length>1){
                            optLog.setRequestPara(JSON.toJSONString(object[1]));
                        }
                    }
                    optLog.setResponsePara(JSON.toJSONString(rtv));//返回参数
                    for (Method method : methods) {
                        if (method.getName().equals(methodName)) {
                            LogAnnotation logAnnotation = method.getAnnotation(LogAnnotation.class);
                            if (logAnnotation != null) {
                                optLog.setDescription(logAnnotation.remark());
                                optLog.setTargetType(logAnnotation.targetType());
    
                            }
                        }
                    }
                    optLog.setOperatorUrl(url);
                    optLog.setMethodName(methodName);
                    optLog.setRemoteAddr(remoteAddr);
                    operatorLogService.operatorLogAdd(optLog, request);
                } catch (Exception e) {
                    logger.error("***操作请求日志记录失败doBefore()***", e);
                }
            }
        }

## 2.1 Pointcut优化部分 ##

//切入点设置到自定义的log注解上
        @Pointcut("@annotation(cn.vobile.hss.annotation.LogAnnotation)")
        private void pointCutMethod(){}

我们可以将切入方法设置到自定义的log注解上，这样aop就会只在有log注解的方法进行拦截了。

1.  特殊字段的注解

@Retention(RetentionPolicy.RUNTIME)//注解会在class中存在，运行时可通过反射获取
    @Target(ElementType.METHOD)//目标是方法
    @Documented//文档生成时，该注解将被包含在javadoc中，可去掉
    public @interface LogAnnotation {
        String targetType() default "";
        String remark() default "";
    }

1.  引用部分

@ApiOperation("商品列表-删除")
        @LogAnnotation(targetType = "ProductInfo-Delete", remark = "商品删除")//切点信息
        @RequestMapping(value = "/deleteProductById", method = RequestMethod.POST)
        public DataOutput deleteProductById(
                HttpServletRequest request,
                @ApiParam(value = "商品Id") @RequestParam(value = "productId") String productId) {
            return productCmsService.deleteProductById(request,productId);
        }
