自定义注解通过aop实现操作日志管理

通过自定义注解，然后在控制层方法上加上此注解，通过aop切面拦截到该方法，获取注解值，实现操作日志管理。

1 自定义注解:

import java.lang.annotation.ElementType;
    import java.lang.annotation.Retention;
    import java.lang.annotation.RetentionPolicy;
    import java.lang.annotation.Target;
    
    @Retention(RetentionPolicy.RUNTIME)
    @Target(ElementType.METHOD)
    public @interface LoggerAnnonation {
        String op();
    }

2  编写切面（在普通类获取request可用使用RequestContextHolder .getCurrentRequestAttributes()）

import com.yc.entity.Logger;
    import com.yc.entity.User;
    import com.yc.service.LoggerService;
    import org.aspectj.lang.JoinPoint;
    import org.aspectj.lang.annotation.After;
    import org.aspectj.lang.annotation.AfterReturning;
    import org.aspectj.lang.annotation.Aspect;
    import org.aspectj.lang.annotation.Pointcut;
    import org.aspectj.lang.reflect.MethodSignature;
    import org.springframework.stereotype.Component;
    import org.springframework.web.context.request.RequestAttributes;
    import org.springframework.web.context.request.RequestContextHolder;
    import org.springframework.web.context.request.ServletRequestAttributes;
    
    import javax.annotation.Resource;
    import javax.servlet.http.HttpServletRequest;
    import java.lang.reflect.Method;
    import java.text.SimpleDateFormat;
    import java.util.Date;
    
    /**

     * @date 2019/3/30
     */
    @Aspect
    @Component
    public class LoggerAspectj {
    
        @Pointcut("execution(* com.yc.controllers..*(..))")
        public void pointcut(){}
        @Resource(name="loggerServiceImpl")
        LoggerService loggerService;
    
        @After(value = "pointcut()")
        public void after(JoinPoint pjp) throws Throwable{
           String methodName= pjp.getSignature().getName();
    
            RequestAttributes requestAttributes = RequestContextHolder.currentRequestAttributes();
    
            //String str = (String) requestAttributes.getAttribute("name", RequestAttributes.SCOPE_SESSION);
    
            HttpServletRequest request = ((ServletRequestAttributes)requestAttributes).getRequest();
            User user=(User)request.getSession().getAttribute("user");
    
            String  ip=request.getRemoteAddr();  //获取ip
            String op="";
           if(ip.equals("0:0:0:0:0:0:0:1")){
               ip="127.0.0.1";
           }
          // System.out.println(ip);
            if(user!=null){
                MethodSignature ms=null;
                ms=(MethodSignature)pjp.getSignature();
                Class[] argType=ms.getMethod().getParameterTypes();
                Method method=pjp.getTarget().getClass().getMethod(methodName,argType);
                if (method.isAnnotationPresent(LoggerAnnonation.class)) {
                    LoggerAnnonation loggerAnnonation=method.getAnnotation(LoggerAnnonation.class);
                     op=loggerAnnonation.op();
                  //  System.out.println(op+"操作日志");
    
                    SimpleDateFormat  sdf=new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
                    String time=sdf.format(new Date());
                    Logger logger=new Logger();
                    logger.setIp(ip);
                    logger.setOp(op);
                    logger.setTime(time);
                    loggerService.add(logger);
                }
            }
    
        }
    }
