Spring + Ibatis + MySql实例详解

1. 环境:
将以下jar包加入到工程,commons-logging-1.0.4.jar、ibatis-2.3.0.677.jar、mysql-connector-java-5.0.3-bin.jar、spring.jar。

2. 在MySql中创建数据库和相应的表:

 

[sql]  view plain copy
 
  1. ############################################################################################# 
  2. CREATE DATABASE MYDB; 
  3. use MYDB; 
  4.  
  5. Drop TABLE IF EXISTS `MYDB`.`student`; 
  6. Create TABLE `MYDB`.`student` ( 
  7. `namevarchar(40) NOT NULL
  8. `psw` varchar(10) NOT NULL
  9. `enabled` boolean 
  10. ); 
  11. insert into student values("lanp","lanpiao",true); 
  12. insert into student values("ph","ph",true); 
  13. insert into student values("wxh","wxh",true); 
[sql]  view plain copy
 
  1. #############################################################################################  
  2. CREATE DATABASE MYDB;  
  3. use MYDB;  
  4.   
  5. Drop TABLE IF EXISTS `MYDB`.`student`;  
  6. Create TABLE `MYDB`.`student` (  
  7. `namevarchar(40) NOT NULL,  
  8. `psw` varchar(10) NOT NULL,  
  9. `enabled` boolean  
  10. );  
  11. insert into student values("lanp","lanpiao",true);  
  12. insert into student values("ph","ph",true);  
  13. insert into student values("wxh","wxh",true);  

 

 

 

3. 创建实体Bean,Student.java

 

[java]  view plain copy
 
  1. package com.lanp.beans; 
  2.  
  3. import java.io.Serializable; 
  4.  
  5. /**

  8. * @since 2011-11-27 15:36
  9. * @version V1.0
  10. */ 
  11. public class Student implements Serializable { 
  12.  
  13.     private static final long serialVersionUID = -7163004163334815825L; 
  14.      
  15.     private String name; 
  16.     private String psw; 
  17.     private Boolean enabled; 
  18.      
  19.     public String getName() { 
  20.         return name; 
  21.     } 
  22.     public void setName(String name) { 
  23.         this.name = name; 
  24.     } 
  25.     public String getPsw() { 
  26.         return psw; 
  27.     } 
  28.     public void setPsw(String psw) { 
  29.         this.psw = psw; 
  30.     } 
  31.     public Boolean getEnabled() { 
  32.         return enabled; 
  33.     } 
  34.     public void setEnabled(Boolean enabled) { 
  35.         this.enabled = enabled; 
  36.     } 
[java]  view plain copy
 
  1. package com.lanp.beans;  
  2.   
  3. import java.io.Serializable;  
  4.   
  5. /** 
  6.  * Student Bean 
  7.  * @author LanP 
  8.  * @since 2011-11-27 15:36 
  9.  * @version V1.0 
  10.  */  
  11. public class Student implements Serializable {  
  12.   
  13.     private static final long serialVersionUID = -7163004163334815825L;  
  14.       
  15.     private String name;  
  16.     private String psw;  
  17.     private Boolean enabled;  
  18.       
  19.     public String getName() {  
  20.         return name;  
  21.     }  
  22.     public void setName(String name) {  
  23.         this.name = name;  
  24.     }  
  25.     public String getPsw() {  
  26.         return psw;  
  27.     }  
  28.     public void setPsw(String psw) {  
  29.         this.psw = psw;  
  30.     }  
  31.     public Boolean getEnabled() {  
  32.         return enabled;  
  33.     }  
  34.     public void setEnabled(Boolean enabled) {  
  35.         this.enabled = enabled;  
  36.     }  
  37. }  

4. 创建Student实体Bean与数据库映射的SQLMap文件,student.xml:

 

 

 

 

[html]  view plain copy
 
  1. <?xml version="1.0" encoding="UTF-8"?> 
  2. <!DOCTYPE sqlMap       
  3.     PUBLIC "-//ibatis.apache.org//DTD SQL Map 2.0//EN"       
  4.     "http://ibatis.apache.org/dtd/sql-map-2.dtd"> 
  5. <sqlMap> 
  6.     <!-- 为Person类设置一个别名 --> 
  7.     <typeAlias alias="student" type="com.lanp.beans.Student"/> 
  8.      
  9.     <!-- 配置表和实体Bean之间的映射关系 --> 
  10.     <resultMap id="studentMap" class="com.lanp.beans.Student"> 
  11.         <result property="name" column="name"/> 
  12.         <result property="psw" column="psw"/> 
  13.         <result property="enabled" column="enabled"/> 
  14.     </resultMap> 
  15.      
  16.     <insert id="insertStudent" parameterClass="student"> 
  17.         <![CDATA[
  18.             insert into student values(#name#,#psw#,#enabled#);
  19.         ]]> 
  20.     </insert> 
  21.      
  22.     <!-- 查看特定用户 --> 
  23.     <select id="queryStudentById" parameterClass="string" resultMap="studentMap"> 
  24.         <![CDATA[
  25.             SELECT * FROM STUDENT WHERE NAME=#name#
  26.         ]]> 
  27.     </select> 
  28.      
  29.     <!-- 查看所有的用户 --> 
  30.     <select id="queryAllStudents" resultMap="studentMap"> 
  31.         <![CDATA[
  32.             SELECT * FROM STUDENT
  33.         ]]> 
  34.     </select> 
  35. </sqlMap> 
[html]  view plain copy
 
  1. <?xml version="1.0" encoding="UTF-8"?>  
  2. <!DOCTYPE sqlMap        
  3.     PUBLIC "-//ibatis.apache.org//DTD SQL Map 2.0//EN"        
  4.     "http://ibatis.apache.org/dtd/sql-map-2.dtd">  
  5. <sqlMap>  
  6.     <!-- 为Person类设置一个别名 -->  
  7.     <typeAlias alias="student" type="com.lanp.beans.Student"/>  
  8.       
  9.     <!-- 配置表和实体Bean之间的映射关系 -->  
  10.     <resultMap id="studentMap" class="com.lanp.beans.Student">  
  11.         <result property="name" column="name"/>  
  12.         <result property="psw" column="psw"/>  
  13.         <result property="enabled" column="enabled"/>  
  14.     </resultMap>  
  15.       
  16.     <insert id="insertStudent" parameterClass="student">  
  17.         <![CDATA[ 
  18.             insert into student values(#name#,#psw#,#enabled#); 
  19.         ]]>  
  20.     </insert>  
  21.       
  22.     <!-- 查看特定用户 -->  
  23.     <select id="queryStudentById" parameterClass="string" resultMap="studentMap">  
  24.         <![CDATA[ 
  25.             SELECT * FROM STUDENT WHERE NAME=#name# 
  26.         ]]>  
  27.     </select>  
  28.       
  29.     <!-- 查看所有的用户 -->  
  30.     <select id="queryAllStudents" resultMap="studentMap">  
  31.         <![CDATA[ 
  32.             SELECT * FROM STUDENT 
  33.         ]]>  
  34.     </select>  
  35. </sqlMap>  

5. 创建访问数据库的DAO接口,StudentDao.java:

 

 

 

 

[java]  view plain copy
 
  1. package com.lanp.dao; 
  2.  
  3. import com.lanp.beans.Student; 
  4.  
  5. public interface StudentDao { 
  6.     Student getStudent(String name); 
[java]  view plain copy
 
  1. package com.lanp.dao;  
  2.   
  3. import com.lanp.beans.Student;  
  4.   
  5. public interface StudentDao {  
  6.     Student getStudent(String name);  
  7. }  

 

 

 

6. 创建访问数据库的DAO接口实现类,StudentDaoImpl.java:

 

[java]  view plain copy
 
  1. package com.lanp.dao; 
  2.  
  3. import org.springframework.orm.ibatis.support.SqlMapClientDaoSupport; 
  4.  
  5. import com.lanp.beans.Student; 
  6.  
  7. public class StudentDaoImpl extends SqlMapClientDaoSupport implements StudentDao { 
  8.  
  9.     @Override 
  10.     public Student getStudent(String name) { 
  11.         try
  12.             return (Student)getSqlMapClientTemplate().queryForObject("queryStudentById", name); 
  13.         } catch(Exception e) { 
  14.             e.printStackTrace(); 
  15.         } 
  16.         return null
  17.     } 
  18.  
[java]  view plain copy
 
  1. package com.lanp.dao;  
  2.   
  3. import org.springframework.orm.ibatis.support.SqlMapClientDaoSupport;  
  4.   
  5. import com.lanp.beans.Student;  
  6.   
  7. public class StudentDaoImpl extends SqlMapClientDaoSupport implements StudentDao {  
  8.   
  9.     @Override  
  10.     public Student getStudent(String name) {  
  11.         try{  
  12.             return (Student)getSqlMapClientTemplate().queryForObject("queryStudentById", name);  
  13.         } catch(Exception e) {  
  14.             e.printStackTrace();  
  15.         }  
  16.         return null;  
  17.     }  
  18.   
  19. }  

 

 

 

7. Ibatis总配置文件,sqlMapConfig.xml:

 

[html]  view plain copy
 
  1. <?xml version="1.0" encoding="UTF-8"?> 
  2. <!DOCTYPE sqlMapConfig       
  3.     PUBLIC "-//ibatis.apache.org//DTD SQL Map Config 2.0//EN"       
  4.     "http://ibatis.apache.org/dtd/sql-map-config-2.dtd"> 
  5. <sqlMapConfig> 
  6.     <!-- 配置Ibatis要使用的SqlMap文件信息 --> 
  7.     <sqlMap resource="com/lanp/beans/student.xml"/> 
  8. </sqlMapConfig> 
[html]  view plain copy
