Springboot1.x与Springboot2.x版本下aop执行顺序

Springboot1.x与Springboot2.x版本下aop执行顺序

Springboot1.x 集成的Spring版本为4.x，Springboot2.x 集成的Spring版本为5.x。

创建SpringBoot项目

编写AOP切面

此案例是用注解实现的切面

AopAnnotation

package com.chinda.interview.annotation;

import java.lang.annotation.*;

@Target(ElementType.METHOD)
@Retention(RetentionPolicy.RUNTIME)
@Documented
public @interface AopAnnotation {
}

AopAspect

package com.chinda.interview.aspect;

import org.aspectj.lang.ProceedingJoinPoint;
import org.aspectj.lang.annotation.*;
import org.springframework.stereotype.Component;

/**
 * @author Wang Chinda
 * @date 2021/4/11
 */
@Aspect
@Component
public class AopAspect {

    @Pointcut("@annotation(com.chinda.interview.annotation.AopAnnotation)")
    private void pointcut() {

    }

    @Before("pointcut()")
    public void beforeNotify() {
        System.out.println("*************************** @Before 我是前置通知AopAspect");
    }

    @After("pointcut()")
    public void afterNotify() {
        System.out.println("*************************** @After 我是后置通知AopAspect");
    }

    @AfterReturning("pointcut()")
    public void returnNotify() {
        System.out.println("*************************** @AfterReturning 我是返回通知AopAspect");
    }

    @AfterThrowing("pointcut()")
    public void throwingNotify() {
        System.out.println("*************************** @AfterThrowing 我是异常通知AopAspect");
    }

    @Around("pointcut()")
    public Object around(ProceedingJoinPoint joinPoint) {
        Object proceed = null;
        try {
            System.out.println("=========================@Around 我是环绕通知目标方法执行前");
            proceed = joinPoint.proceed();
            System.out.println("=========================@Around 我是环绕通知目标方法执行后");
        } catch (Throwable throwable) {
            System.out.println("=========================@Around 我是环绕通知的执行异常");
            throwable.printStackTrace();
        } finally {
            System.out.println("=========================@Around 我是环绕通知的finally");
        }
        return proceed;
    }
}

AopService

package com.chinda.interview.service;

/**
 * @author Wang Chinda
 * @date 2021/4/11
 */
public interface AopService {
    int div(int x, int y);
}

AopServiceImpl

package com.chinda.interview.service.impl;

import com.chinda.interview.annotation.AopAnnotation;
import com.chinda.interview.service.AopService;
import org.springframework.stereotype.Service;

/**
 * @author Wang Chinda
 * @date 2021/4/11
 */
@Service
public class AopServiceImpl implements AopService {

    @Override
    @AopAnnotation
    public int div(int x, int y) {
        return x / y;
    }
}

编写测试用例

1.x 版本

package com.chinda.interview;

import com.chinda.interview.service.AopService;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.SpringBootVersion;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.core.SpringVersion;
import org.springframework.test.context.junit4.SpringRunner;

@SpringBootTest
@RunWith(SpringRunner.class)
public class InterviewApplicationTests {
    @Autowired
    private AopService aopService;


    @Test
    public void boot1() {
        System.out.println("Spring版本: " + SpringVersion.getVersion() + "\t SpringBoot版本: " + SpringBootVersion.getVersion());
        System.out.println();
        aopService.div(10, 2);
    }

    @Test
    public void boot1Throwing() {
        System.out.println("Spring版本: " + SpringVersion.getVersion() + "\t SpringBoot版本: " + SpringBootVersion.getVersion());
        System.out.println();
        aopService.div(10, 0);
    }

    @Test
    public void boot2() {
        System.out.println("Spring版本: " + SpringVersion.getVersion() + "\t SpringBoot版本: " + SpringBootVersion.getVersion());
        System.out.println();
        aopService.div(10, 2);
    }

    @Test
    public void boot2Throwing() {
        System.out.println("Spring版本: " + SpringVersion.getVersion() + "\t SpringBoot版本: " + SpringBootVersion.getVersion());
        System.out.println();
        aopService.div(10, 0);
    }

}

2.x版本

package com.chinda.interview;

import com.chinda.interview.service.AopService;
import org.junit.jupiter.api.Test;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.SpringBootVersion;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.core.SpringVersion;

@SpringBootTest
class InterviewApplicationTests {
    @Autowired
    private AopService aopService;


    @Test
    void boot1() {
        System.out.println("Spring版本: " + SpringVersion.getVersion() + "\t SpringBoot版本: " + SpringBootVersion.getVersion());
        System.out.println();
        aopService.div(10, 2);
    }

    @Test
    void boot1Throwing() {
        System.out.println("Spring版本: " + SpringVersion.getVersion() + "\t SpringBoot版本: " + SpringBootVersion.getVersion());
        System.out.println();
        aopService.div(10, 2);
    }

    @Test
    void boot2() {
        System.out.println("Spring版本: " + SpringVersion.getVersion() + "\t SpringBoot版本: " + SpringBootVersion.getVersion());
        System.out.println();
        aopService.div(10, 2);
    }

    @Test
    void boot2Throwing() {
        System.out.println("Spring版本: " + SpringVersion.getVersion() + "\t SpringBoot版本: " + SpringBootVersion.getVersion());
        System.out.println();
        aopService.div(10, 2);
    }

}
