用户操作拦截并作日志记录--自定义注解+AOP拦截技术讲解

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service
        System.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="com.bbc_kit.common.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
