Spring Aop使用demo（Spring Boot）-蒲公英云

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;
import org.aspectj.lang.annotation.AfterThrowing;
