Aop实现日志的service层的拦截

Posted 2023-02-21 Ashan-Da宝旗

注意：该拦截只适用于service的实现类

1.自定义注解

package com.chinook5.util;

import java.lang.annotation.Retention;
import java.lang.annotation.Target;
import java.lang.annotation.RetentionPolicy;
import java.lang.annotation.ElementType;

/**
 * Created by Bertram on 2017/2/23.
 */
@Retention(RetentionPolicy.RUNTIME)
@Target( ElementType.METHOD )
public @interface DBLog 
    String description() default "";

2.拦截方法体

package com.chinook5.util;

import java.lang.reflect.Method;

import org.aspectj.lang.JoinPoint;
import org.aspectj.lang.annotation.After;
import org.aspectj.lang.annotation.Aspect;
import org.aspectj.lang.annotation.Pointcut;
import org.aspectj.lang.reflect.MethodSignature;
import org.springframework.stereotype.Component;

/**
 * Created by Bertram on 2017/2/23.
 */
@Aspect
@Component
public class LogAop 
	
//	@Resource(name="logService")
//	private LogService logService;
	
	@Pointcut("@annotation(com.chinook5.util.DBLog)")
	public void log()
	
	    
	@After("log()")
	public void afterExec(JoinPoint joinPoint) throws Exception
		MethodSignature ms=(MethodSignature) joinPoint.getSignature();
		Method method=ms.getMethod();

/*		Subject currentUser = SecurityUtils.getSubject();
		Session session = currentUser.getSession();
		User user = (User)session.getAttribute(Const.SESSION_USER);
*/
		String m=method.getName();
		String name=method.getAnnotation(DBLog.class).description();
		System.out.println(m+name);
	
	     

3.在spring里面配置

<aop:aspectj-autoproxy proxy-target-class="true" />

4.在service层添加注解

    @Resource
    private DaoSupport dao;
    @DBLog(description = "添加")
    public boolean insertUserInfo(String name) throws Exception 
       Integer count =(Integer) dao.save("UserInfoMapper.insertUserInfo",name);
        if(count > 0)
            return true;
        
        return false;
