1.advice 按照以下的顺序执行
输出结果:(正常和异常)
说明:Spring boot 2.3.4.RELEASE 版本使用的AOP是spring-aop-5.2.9.RELEASE,AOP的通知顺序不一样。
可以测试下Spring boot 2.1.1.RELEASE 版做对比,发现结果是不一样的。
2.代码实现
public class User {
private String userName;
private String password;
public String getUserName() {
return userName;
}
public void setUserName(String userName) {
this.userName = userName;
}
public String getPassword() {
return password;
}
public void setPassword(String password) {
this.password = password;
}
@Override
public String toString() {
return "User [userName=" + userName + ", password=" + password + "]";
}
}
public interface UserService {
public void printUser(User user);
}
@Service
public class UserServiceImpl implements UserService {
@Override
public void printUser(User user) {
System.out.println(user.toString());
}
}
//定义切面
@Aspect
public class MyAspect {
//定义切点
@Pointcut("execution(* com.springbootTest.aop.service.impl.UserServiceImpl.printUser(..))")
public void pointCut() {
}
@Before("pointCut()")
public void before() {
System.out.println("-----Before-----");
}
@After("pointCut()")
public void after() {
System.out.println("-----After-----");
}
@AfterReturning("pointCut()")
public void afterReturning() {
System.out.println("-----AfterReturning-----");
//System.out.println("事务提交");
}
@AfterThrowing("pointCut()")
public void afterThrowing() {
System.out.println("-----AfterThrowing-----");
//System.out.println("事务回滚");
}
@Around("pointCut()")
public void around(ProceedingJoinPoint pjp) throws Throwable{
System.out.println("around advise 1");
pjp.proceed();//回调目标对象的原有方法
System.out.println("around advise2");
}
}
@SpringBootApplication
public class AopApplication {
@Bean("myAspect")
public MyAspect getMyAspect() {
return new MyAspect();
}
public static void main(String[] args) {
SpringApplication.run(AopApplication.class, args);
}
}
