com.hrbust.aspect.LogAspect

applicationContext.xml

com.hrbust.test.StuTest

见代码目录

步骤：

1. 在eclipse下创建项目stuManagement
2. 添加.jar包（参照chapter03）
3. 在src下创建com.hrbust.po.Student类,包含属性：String类型stuNo,stuName和score（Integer）
4. 在src下创建com.hrbust.dao.StudentDao接口及其实现类StudentDaoImpl，使用jdbcTemplate实现Student的增删改查操作
5. 在src下创建com.hrbust.aspect.LogAspect切面，定义环绕通知myAround()，实现日志环绕记录功能。
6. 在src下创建applicationContext.xml文件，文件配置参考chapter03
7. 在src下创建com.hrbust.test.StuTest类，调用selectStu()、insertStu()方法。

 com.hrbust.po.Student类

package com.hrbust.po;

public class Student {
       String stuNo;
       String stuName;
       Integer score;

    public String getStuNo() {
        return stuNo;
    }

    public void setStuNo(String stuNo) {
        this.stuNo = stuNo;
    }

    public String getStuName() {
        return stuName;
    }

    public void setStuName(String stuName) {
        this.stuName = stuName;
    }

    public Integer getScore() {
        return score;
    }

    public void setScore(Integer score) {
        this.score = score;
    }

    @Override
    public String toString() {
        return "Student{" +
                "stuNo='" + stuNo + ''' +
                ", stuName='" + stuName + ''' +
                ", score=" + score +
                '}';
    }
}

com.hrbust.dao.StudentDao接口

package com.hrbust.dao;

    public int insert(Student student);
    public List select();

    }
    public int insert(Student student) {
      String sql = "insert into students(stuNo,stuName,score) value(?,?,?)";
      Object[] obj = new Object[]{
        student.getStuNo(),
        student.getStuName(),
        student.getScore()
      };
      int num = this.jdbcTemplate.update(sql,obj);
      System.out.println("插入信息成功");
      return num;
    }

    public List select() {
        String sql = "select * from students";
        RowMapper rowMapper = new BeanPropertyRowMapper(Student.class);
        System.out.println("查询用户信息");
        return this.jdbcTemplate.query(sql,rowMapper);
    }
}

com.hrbust.aspect.LogAspect

package com.hrbust.aspect;
import org.aspectj.lang.JoinPoint;
import org.aspectj.lang.ProceedingJoinPoint;
import org.aspectj.lang.annotation.*;

@Aspect
public class LogAspect {
    @Pointcut("execution( * com.hrbust.dao.StudentDaoImpl.*(..))")
    public void pointcut(){

    }

    @Around("pointcut()")
    public Object myAround(ProceedingJoinPoint point)throws Throwable{
        System.out.println("这是环绕通知:执行目标方法之前，模拟开启事务");
        Object object = point.proceed();
        System.out.println("这是环绕之后的部分：执行方法之后，模拟关闭事务");
        return object;
    }

}

applicationContext.xml

com.hrbust.test.StuTest

        Student student = new Student();
        student.setStuNo("1234");
