作为运营除了处理系统生产问题，还要处理大量的用户上报事件，这部分工作占用了大量的人力。所有考虑把一部分事件查询处理做成一个自助平台，让用户自行核查处理。于是就有了用户自助系统。考虑到如何计量这个工具平台具体的实现价值，需要做用户操作统计才能给出可信服的数据。
以上就是本文的背景。自助系统的架构就是传统的springmvc+spinrg+mybatis+oracle。想到日志记录首先想到的就是AOP拦截处理。网上相关的技术贴很多。简单的小项目遇到的问题一般度娘都能给解决了~\(≧▽≦)/~
自定义注解：
@Retention(RetentionPolicy.RUNTIME)@Target(ElementType.METHOD)public @interface LogAnnotation {String operateModelName() default "";String operateFuncName() default "";String operationType() default ""; String operateDescribe() default "";}
在controller层引用注解
@Controller@RequestMapping(value="/kit")public class QueryClientInfoController {@Resourceprivate IClientService clientService;private Logger logger = Logger.getLogger(this.getClass().getName());@RequestMapping(value="/queryClientRegInfo")@LogAnnotation(operateModelName="用户注册模块",operateFuncName="queryClientRegInfo",operationType="query",operateDescribe="查询客户注册信息")public void queryClientRegInfo(HttpServletRequest request,HttpServletResponse response){String client_idno = request.getParameter("idno");Client client = clientService.queryClientRegInfo(client_idno);//调用serviceSystem.out.println("queryClientRegInfo:"+client.getName());String jsonMap = JSON.toJSONString(client);response.setCharacterEncoding("UTF-8");try {response.getWriter().write(jsonMap);response.getWriter().flush();response.getWriter().close();} catch (IOException e) {e.printStackTrace();} }}
查询用户注册信息相关其他的service层等具体实现代码就不贴出来了。
拦截器的实现
@Service(value="userLogService")public class UserLogServiceImpl implements IUserLogService {@Resourceprivate UserLogDao userLogDao;@Overridepublic void insert(UserLog record) {return userLogDao.insert(record);}@Overridepublic void logBusiController(JoinPoint joinPoint) {Map<String, Object> map = new HashMap<String, Object>();String targetName = joinPoint.getTarget().getClass().getName();String methodName = joinPoint.getSignature().getName();Object[] arguments = joinPoint.getArgs();Class targetClass;try {targetClass = Class.forName(targetName);Method[] methods = targetClass.getMethods();for (Method method : methods) {if(method.getName().equals(methodName)) {Class[] clazzs = method.getParameterTypes();if(clazzs.length == arguments.length ) {if(method.getAnnotation(LogAnnotation.class)!= null){map.put("operateModelName", method.getAnnotation(LogAnnotation.class).operateModelName());map.put("operateFuncName", method.getAnnotation(LogAnnotation.class).operateFuncName());map.put("operationType", method.getAnnotation(LogAnnotation.class).operationType());map.put("operateDescribe", method.getAnnotation(LogAnnotation.class).operateDescribe());}elsebreak;}}}} catch (ClassNotFoundException e) {e.printStackTrace();}HttpServletRequest request =((ServletRequestAttributes) RequestContextHolder.getRequestAttributes()).getRequest(); HttpSession session =request.getSession(); User user = (User) session.getAttribute("currentUser"); System.out.println("currentUser:"+user.getName()+"\n targetName:"+targetName+"\n methodName:"+methodName+"\n operateModelName:"+map.get("operateModelName")+"\n operateFuncName:"+map.get("operateFuncName")+"\n operationType:"+map.get("operationType")+"\n operateDescribe:"+map.get("operateDescribe"));}}
接下来需要再配置文件中做拦截设置：
在spring-mvc.xml中增加
<bean id="LogService" class="mon.service.impl.UserLogServiceImpl"></bean><aop:config><aop:pointcut id="logBusiControllerPoint" expression="execution(* com.bbc_kit.business.controller..*.*(..))" /><aop:aspect id="logService" ref="LogService"><aop:after pointcut-ref="logBusiControllerPoint" method="logBusiController"/></aop:aspect></aop:config>
我的controller原来就是在mvc配置中做的扫描注入，service是在applicationContext.xml中做的扫描注入。所有要拦截service层的操作，可以把上面的配置微调下放置在applicationContext.xml中。
调用该.do后后台日志输出
currentUser:renhuang
targetName:com.bbc_kit.business.controller.QueryClientInfoController
methodName:queryClientRegInfo
operateModelName:用户注册模块
operateFuncName:queryClientRegInfo
operationType:query
operateDescribe:查询客户注册信息
