pom.xml：

<dependencies>
    		<dependency>
    			<groupId>org.springframework.boot</groupId>
    			<artifactId>spring-boot-starter-web</artifactId>
    		</dependency>
    
    		<dependency>
    			<groupId>org.springframework.boot</groupId>
    			<artifactId>spring-boot-starter-aop</artifactId>
    		</dependency>
    
    
    		<dependency>
    			<groupId>org.springframework.boot</groupId>
    			<artifactId>spring-boot-starter-test</artifactId>
    			<scope>test</scope>
    		</dependency>
    	</dependencies>

创建User类：

package com.example.demo.dao;
    /* 
    * @author zzf 
    * @date 2018年11月19日 下午5:19:28 
    */
    public class User {
    
    	String name;
    	Integer age;
    	public String getName() {
    		return name;
    	}
    	public void setName(String name) {
    		this.name = name;
    	}
    	public Integer getAge() {
    		return age;
    	}
    	public void setAge(Integer age) {
    		this.age = age;
    	}
    	public User(String name, Integer age) {
    		super();
    		this.name = name;
    		this.age = age;
    	}
    	@Override
    	public String toString() {
    		return "User [name=" + name + ", age=" + age + "]";
    	}
    	
    }

创建接口：

package com.example.demo.concert;
    
    import com.example.demo.dao.User;
    
    /* 
    * @author zzf 
    * @date 2018年11月19日 上午11:09:02 
    */
    public interface Performance {
    
    	public void perform1();
    	
    	public void perform2() throws Exception;
    	
    	public void perform3(int age,String name);
    	
    	public void perform4(User user);
    }

实现类：

package com.example.demo.concert.impl;
    
    import org.springframework.stereotype.Component;
    
    import com.example.demo.concert.Performance;
    import com.example.demo.dao.User;
    
    /* 
    * @author zzf 
    * @date 2018年11月19日 下午1:33:49 
    */
    @Component
    public class PerformanceImpl implements Performance{
    
    	@Override
    	public void perform1() {
    		// TODO Auto-generated method stub
    		System.out.println("方法运行1");
    	}
    
    	@Override
    	public void perform2() throws Exception {
    		// TODO Auto-generated method stub
    		// TODO Auto-generated method stub
    		System.out.println("方法运行2");
    		throw new Exception("抛出异常");
    	}
    
    	@Override
    	public void perform3(int age,String name) {
    		// TODO Auto-generated method stub
    		System.out.println("方法运行-age:"+age+"-name:"+name);
    	}
    
    	@Override
    	public void perform4(User user) {
    		// TODO Auto-generated method stub
    		System.out.println(user);
    	}
    
    
    }

切面类：

package com.example.demo;
    
    import org.aspectj.lang.ProceedingJoinPoint;
    import org.aspectj.lang.annotation.After;
    import org.aspectj.lang.annotation.AfterReturning;

    */
    @Aspect
    @Component
    public class Audience {
    	
    	
    	//定义切点
    	@Pointcut("execution(** com.example.demo.concert.Performance.*(..))")//所有的方法任意参数
    	public void performance() {}
    	//传递单个值
    	@Pointcut("execution(** com.example.demo.concert.Performance.*(int,String)) && args(age,name)")
    	public void performance2(int age,String name) {}
    	//传递对象
    	@Pointcut("execution(** com.example.demo.concert.Performance.*(com.example.demo.dao.User)) && args(user)")
    	public void performance3(User user) {}
    	
    	@Before("performance()")
    	public void beforePerformance1() {
    		System.out.println("performance-方法开始前1");
    	}
    	
    	@Before("performance()")
    	public void beforePerformance2() {
    		System.out.println("performance-方法开始前2");
    	}
    	
    	@AfterReturning("performance()")
    	public void AfterPerformance() {
    		System.out.println("performance-方法正常退出后");
    	}
    	
    	@AfterThrowing("performance()")
    	public void AfterTrownPerformance() {
    		System.out.println("performance-方法异常退出");
    	}
    	
    	@Around("performance()")
    	public void AroudPerformance(ProceedingJoinPoint jp) throws Throwable {
    		System.out.println("performance-环绕通知方法前");
    		jp.proceed();
    		System.out.println("performance-环绕通知方法后");
    	}
    	/***************************************************************/
    	@Before("performance2(age,name)")

    	@Before("performance2(age,name)")
    	public void beforePerformance2_2(int age,String name) {

    	@AfterReturning("performance2(age,name)")
    	public void AfterPerformance2(int age,String name) {

    		jp.proceed();
    		System.out.println("performance3-环绕通知方法后-User:"+user);
    	}
    }
