Spring+Ibatis集成开发实例

首先简历数据库demo(本文选mysql)

数据库脚本:

 

CREATE   TABLE  `ibatis` (
  `id` 
varchar ( 20 NOT   NULL ,
  `name` 
varchar ( 20 default   NULL ,
  
PRIMARY   KEY   (`id`)
) ENGINE
= InnoDB  DEFAULT  CHARSET = gb2312;

insert   into  ibatis  values (" 1 "," 1 ");
insert   into  ibatis  values (" 2 "," 2 ");

 

DAO接口:

 

package  ch10.SpringAndIbatis;

import  java.util.List;

public   interface  IDAO  {
  
public List getList();
  
public Ibatis getByName(String name);
  
public Ibatis getById(String id);
  
public void save(Ibatis ibatis);
  
public void delete(String id);
  
public void update(Ibatis ibatis);
}

 

Ibatis配置文件:

 

<? xml version="1.0" encoding="UTF-8" ?>  
<! DOCTYPE sqlMapConfig 
PUBLIC "-//iBATIS.com//DTD SQL Map Config 2.0//EN" 
"http://www.ibatis.com/dtd/sql-map-config-2.dtd"
>  
< sqlMapConfig >  

< sqlMap  resource ="ch10/SpringAndIbatis/Ibatis.xml"   />  

</ sqlMapConfig >

 

ibatis sql map文件ibatis.xml:

 

<? xml version="1.0" encoding="UTF-8"  ?>
<! DOCTYPE sqlMap PUBLIC "-//ibatis.apache.org//DTD SQL Map 2.0//EN" "http://ibatis.apache.org/dtd/sql-map-2.dtd"  >

< result  column ="id"  property ="id"  jdbcType ="VARCHAR"   />
    
< result  column ="name"  property ="name"  jdbcType ="VARCHAR"   />
  
</ resultMap >
  
  
<!--  获得全查询列表  -->
  
< select  id ="getAllUsers"  resultMap ="ibatisTest" >
    select * from Ibatis
  
</ select >
  
   
<!--  依据username获得用户对象  -->
   
< select  id ="getUsersByName"  resultMap ="ibatisTest" >
     select * from Ibatis where name=#value#
  
</ select >  
  
  
<!--  依据id获得用户对象  -->
    
< select  id ="getUsersById"  resultMap ="ibatisTest" >
     select * from Ibatis where id=#value#
  
</ select >  
  
   
<!--  新增用户对象  -->
   
< insert  id ="insertUsers"  parameterClass ="user" >
      insert into ibatis (id,name) values (#id#,#name#)
   
</ insert >
   
   
<!--  删除用户对象  -->
   
< delete  id ="deleteUsers" >
     delete from ibatis where id=#value#
   
</ delete >
   
   
<!--  更新用户对象  -->
   
< delete  id ="updateUsers"  parameterClass ="user" >
      update ibatis set name=#name# where id=#id#
   
</ delete >
</ sqlMap >

DAO实现类:

 

package  ch10.SpringAndIbatis;

import  java.util.List;

import  org.springframework.orm.ibatis.support.SqlMapClientDaoSupport;

public   class  TestDAO  extends  SqlMapClientDaoSupport  implements  IDAO  {

    
public void delete(String id) {
        getSqlMapClientTemplate().delete(
"deleteUsers", id);
    }


    
public Ibatis getById(String id) {
        
return (Ibatis)getSqlMapClientTemplate().queryForObject("getUsersById",id);
    }


    
public Ibatis getByName(String name) {
        
        
return (Ibatis)getSqlMapClientTemplate().queryForObject("getUsersByName",name);
    }


    
public List getList() {
        
return getSqlMapClientTemplate().queryForList("getAllUsers",null);
    }


    
public void save(Ibatis ibatis) {
        getSqlMapClientTemplate().insert(
"insertUsers",ibatis);
    }


    
public void update(Ibatis ibatis) {
        getSqlMapClientTemplate().update(
"updateUsers", ibatis);
    }


}

domain对象

 

package  ch10.SpringAndIbatis;

public   class  Ibatis  {
  

private String id;
   
private String name;
   
public String getId() {
        
return id;
   }

   
public void setId(String id) {
        
this.id = id;
   }

   
public String getName() {
        
return name;
   }

   
public void setName(String name) {
        
this.name = name;
   }

   
public Ibatis(){
       
   }

public Ibatis(String id, String name) {
    
super();
    
this.id = id;
    
this.name = name;
}

}
