Spring + Struts +Mybatis 实现单表的增删改查
Bean
package com.ambow.bean;
public class DeptBean {
private int id;
private String dname;
public int getId() {
return id;
}
public void setId(int id) {
this.id = id;
}
public String getDname() {
return dname;
}
public void setDname(String dname) {
this.dname = dname;
}
public DeptBean() {
super();
}
public DeptBean(int id, String dname) {
super();
this.id = id;
this.dname = dname;
}
@Override
public String toString() {
return "DeptBean [id=" + id + ", dname=" + dname + "]";
}
}
Mapper层
package com.ambow.mapper;
import java.util.List;
import com.ambow.bean.DeptBean;
public interface DeptMapper {
/**
* dept表CRUD
* @param id
* @return
*/
//根据id查
public DeptBean getById(int id);
//查询所有
public List<DeptBean> getAll();
//添加
public void deptAdd(DeptBean deptBean);
//删除
public void deptDel(int id);
//修改
public void deptUpdate(DeptBean deptBean);
//模糊查询
public List<DeptBean> getMoHu(String dname);
}
Mapper映射文件
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN" "http://mybatis.org/dtd/mybatis-3-mapper.dtd">
<!-- 为这个mapper指定一个唯一的namespace，namespace的值习惯上设置成包名+sql映射文件名，这样就能够保证namespace的值是唯一的
例如namespace="me.gacl.mapping.userMapper"就是me.gacl.mapping(包名)+userMapper(userMapper.xml文件去除后缀) -->
<mapper namespace="com.ambow.mapper.DeptMapper">
<!--根据id查 -->
<select id="getById" parameterType="int" resultType="DeptBean">
select * from tb_dept where id=#{id}

<!-- 查所有 -->
<select id="getAll" resultType="DeptBean">
select * from tb_dept

<!-- 添加 -->
<insert id="deptAdd" parameterType="com.ambow.bean.DeptBean">
insert into tb_dept values(null,#{dname})
</insert>
<!-- 删除 -->
