spring boot 实现 AOP

切面配置
@Component
@Aspect
public class HelloAspect {
    @Pointcut("execution(* com.educationtek.daoxue.controller.*.*(..))")
    public void pointCut() {

    }

    @Before("pointCut()")
    public void begin(){
        System.out.println("开启事务");
    }

    @After("pointCut()")
    public void close(){
        System.out.println("关闭事务");
    }
}

业务逻辑

@RestController
@RequestMapping(value = "/api/hello")
public class HelloController {
    @GetMapping("/aop")
    public String printString(){
        System.out.println("hello,Aop!");
        return "hello,Aop";
    }

}

程序输出
