mybatis开发流程，增删改查

一、开发流程

1)引jar包

//mybatis_core
mybatis3.4core\asm-5.2.jar
mybatis3.4core\cglib-3.2.5.jar
mybatis3.4core\commons-logging-1.2.jar
mybatis3.4core\log4j-1.2.17.jar
mybatis3.4core\mybatis-3.4.4.jar

//db connector
DB-connector\mysql-connector-java-5.1.40-bin.jar

2)变写实体类Student

package com.huitong.entity;

public class Student {
    
    private Integer id;
    private String sname;
    private double salary;
    
    public Integer getId() {
        return id;
    }
    public void setId(Integer id) {
        this.id = id;
    }
    public String getSname() {
        return sname;
    }
    public void setSname(String sname) {
        this.sname = sname;
    }
    
    
    public double getSalary() {
        return salary;
    }
    public void setSalary(double salary) {
        this.salary = salary;
    }
    @Override
    public String toString() {
        return sname + ":" + salary;
    }

}
