基于注解和AOP方式实现简单的学生信息管理

//Student.java
package com.xzk.po;

public interface Student {
	public void insertUser();
	public void selectUser();
}
//CollegeStudent.java
package com.xzk.po;

import org.springframework.stereotype.Repository;

@Repository("student")
public class CollegeStudent implements Student {
		private String stuNo;
		private String stuName;
		private Integer score;
		public void insertUser() {
			System.out.println("添加用户成功！！！");
		}
		public void selectUser() {
			System.out.println("查找用户成功！！！！");
		}
}
//LosAspect.java
package com.xzk.aspect;

import org.aspectj.lang.ProceedingJoinPoint;
import org.aspectj.lang.annotation.Around;
import org.aspectj.lang.annotation.Aspect;
import org.aspectj.lang.annotation.Pointcut;
import org.springframework.stereotype.Component;

@Aspect
@Component
public class LosAspect {
	@Pointcut("execution(* com.xzk.po.*.*(..))")
	private void myPointCut(){}
	
	@Around("myPointCut()")
	public Object myAround(ProceedingJoinPoint proceedingJoinPoint) 
            throws Throwable {
		// 开始
		System.out.println("环绕开始：执行目标方法之前，模拟开启事务...");
		// 执行当前目标方法
		Object obj = proceedingJoinPoint.proceed();
		// 结束
		System.out.println("环绕结束：执行目标方法之后，模拟关闭事务...");
		return obj;
	}
}
