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:
- #############################################################################################
- CREATE DATABASE MYDB;
- use MYDB;
- Drop TABLE IF EXISTS `MYDB`.`student`;
- Create TABLE `MYDB`.`student` (
- `name` varchar(40) NOT NULL,
- `psw` varchar(10) NOT NULL,
- `enabled` boolean
- );
- insert into student values("lanp","lanpiao",true);
- insert into student values("ph","ph",true);
- insert into student values("wxh","wxh",true);
- #############################################################################################
- CREATE DATABASE MYDB;
- use MYDB;
- Drop TABLE IF EXISTS `MYDB`.`student`;
- Create TABLE `MYDB`.`student` (
- `name` varchar(40) NOT NULL,
- `psw` varchar(10) NOT NULL,
- `enabled` boolean
- );
- insert into student values("lanp","lanpiao",true);
- insert into student values("ph","ph",true);
- insert into student values("wxh","wxh",true);
3. 创建实体Bean,Student.java
- package com.lanp.beans;
- import java.io.Serializable;
- /**
- * Student Bean
- * @author LanP
- * @since 2011-11-27 15:36
- * @version V1.0
- */
- public class Student implements Serializable {
- private static final long serialVersionUID = -7163004163334815825L;
- private String name;
- private String psw;
- private Boolean enabled;
- public String getName() {
- return name;
- }
- public void setName(String name) {
- this.name = name;
- }
- public String getPsw() {
- return psw;
- }
- public void setPsw(String psw) {
- this.psw = psw;
- }
- public Boolean getEnabled() {
- return enabled;
- }
- public void setEnabled(Boolean enabled) {
- this.enabled = enabled;
- }
- }
- package com.lanp.beans;
- import java.io.Serializable;
- /**
- * Student Bean
- * @author LanP
- * @since 2011-11-27 15:36
- * @version V1.0
- */
- public class Student implements Serializable {
- private static final long serialVersionUID = -7163004163334815825L;
- private String name;
- private String psw;
- private Boolean enabled;
- public String getName() {
- return name;
- }
- public void setName(String name) {
- this.name = name;
- }
- public String getPsw() {
- return psw;
- }
- public void setPsw(String psw) {
- this.psw = psw;
- }
- public Boolean getEnabled() {
- return enabled;
- }
- public void setEnabled(Boolean enabled) {
- this.enabled = enabled;
- }
- }
4. 创建Student实体Bean与数据库映射的SQLMap文件,student.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">
- <sqlMap>
- <!-- 为Person类设置一个别名 -->
- <typeAlias alias="student" type="com.lanp.beans.Student"/>
- <!-- 配置表和实体Bean之间的映射关系 -->
- <resultMap id="studentMap" class="com.lanp.beans.Student">
- <result property="name" column="name"/>
- <result property="psw" column="psw"/>
- <result property="enabled" column="enabled"/>
- </resultMap>
- <insert id="insertStudent" parameterClass="student">
- <![CDATA[
- insert into student values(#name#,#psw#,#enabled#);
- ]]>
- </insert>
- <!-- 查看特定用户 -->
- <select id="queryStudentById" parameterClass="string" resultMap="studentMap">
- <![CDATA[
- SELECT * FROM STUDENT WHERE NAME=#name#
- ]]>
- </select>
- <!-- 查看所有的用户 -->
- <select id="queryAllStudents" resultMap="studentMap">
- <![CDATA[
- SELECT * FROM STUDENT
- ]]>
- </select>
- </sqlMap>
- <?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">
- <sqlMap>
- <!-- 为Person类设置一个别名 -->
- <typeAlias alias="student" type="com.lanp.beans.Student"/>
- <!-- 配置表和实体Bean之间的映射关系 -->
- <resultMap id="studentMap" class="com.lanp.beans.Student">
- <result property="name" column="name"/>
- <result property="psw" column="psw"/>
- <result property="enabled" column="enabled"/>
- </resultMap>
- <insert id="insertStudent" parameterClass="student">
- <![CDATA[
- insert into student values(#name#,#psw#,#enabled#);
- ]]>
- </insert>
- <!-- 查看特定用户 -->
- <select id="queryStudentById" parameterClass="string" resultMap="studentMap">
- <![CDATA[
- SELECT * FROM STUDENT WHERE NAME=#name#
- ]]>
- </select>
- <!-- 查看所有的用户 -->
- <select id="queryAllStudents" resultMap="studentMap">
- <![CDATA[
- SELECT * FROM STUDENT
- ]]>
- </select>
- </sqlMap>
5. 创建访问数据库的DAO接口,StudentDao.java:
- package com.lanp.dao;
- import com.lanp.beans.Student;
- public interface StudentDao {
- Student getStudent(String name);
- }
- package com.lanp.dao;
- import com.lanp.beans.Student;
- public interface StudentDao {
- Student getStudent(String name);
- }
6. 创建访问数据库的DAO接口实现类,StudentDaoImpl.java:
- package com.lanp.dao;
- import org.springframework.orm.ibatis.support.SqlMapClientDaoSupport;
- import com.lanp.beans.Student;
- public class StudentDaoImpl extends SqlMapClientDaoSupport implements StudentDao {
- @Override
- public Student getStudent(String name) {
- try{
- return (Student)getSqlMapClientTemplate().queryForObject("queryStudentById", name);
- } catch(Exception e) {
- e.printStackTrace();
- }
- return null;
- }
- }
- package com.lanp.dao;
- import org.springframework.orm.ibatis.support.SqlMapClientDaoSupport;
- import com.lanp.beans.Student;
- public class StudentDaoImpl extends SqlMapClientDaoSupport implements StudentDao {
- @Override
- public Student getStudent(String name) {
- try{
- return (Student)getSqlMapClientTemplate().queryForObject("queryStudentById", name);
- } catch(Exception e) {
- e.printStackTrace();
- }
- return null;
- }
- }
7. Ibatis总配置文件,sqlMapConfig.xml:
- <?xml version="1.0" encoding="UTF-8"?>
- <!DOCTYPE sqlMapConfig
- PUBLIC "-//ibatis.apache.org//DTD SQL Map Config 2.0//EN"
- "http://ibatis.apache.org/dtd/sql-map-config-2.dtd">
- <sqlMapConfig>
- <!-- 配置Ibatis要使用的SqlMap文件信息 -->
- <sqlMap resource="com/lanp/beans/student.xml"/>
- </sqlMapConfig>
- <?xml version="1.0" encoding="UTF-8"?>
- <!DOCTYPE sqlMapConfig
- PUBLIC "-//ibatis.apache.org//DTD SQL Map Config 2.0//EN"
- "http://ibatis.apache.org/dtd/sql-map-config-2.dtd">
- <sqlMapConfig>
- <!-- 配置Ibatis要使用的SqlMap文件信息 -->
- <sqlMap resource="com/lanp/beans/student.xml"/>
- </sqlMapConfig>
8. spring配置文件,SQLMapClient.xml:
- <?xml version="1.0" encoding="UTF-8"?>
- <!DOCTYPE beans PUBLIC "-//SPRING//DTD BEAN//EN" "http://www.springframework.org/dtd/spring-beans.dtd">
- <beans>
- <!-- 相关数据源和事务管理的定义 -->
- <bean id="dataSource"class="org.springframework.jdbc.datasource.DriverManagerDataSource">
- <property name="driverClassName" value="com.mysql.jdbc.Driver"/>
- <property name="url" value="jdbc:mysql://127.0.0.1:3306/MYDB"/>
- <property name="username" value="root"/>
- <property name="password" value="157891"/>
- </bean>
- <bean id="sqlMapClient"class="org.springframework.orm.ibatis.SqlMapClientFactoryBean">
- <property name="configLocation">
- <value>sqlMapConfig.xml</value>
- </property>
- <property name="dataSource">
- <ref bean="dataSource"/>
- </property>
- </bean>
- <bean id="studentDao" class="com.lanp.dao.StudentDaoImpl">
- <property name="sqlMapClient">
- <ref bean="sqlMapClient"/>
- </property>
- </bean>
- </beans>
- <?xml version="1.0" encoding="UTF-8"?>
- <!DOCTYPE beans PUBLIC "-//SPRING//DTD BEAN//EN" "http://www.springframework.org/dtd/spring-beans.dtd">
- <beans>
- <!-- 相关数据源和事务管理的定义 -->
- <bean id="dataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource">
- <property name="driverClassName" value="com.mysql.jdbc.Driver"/>
- <property name="url" value="jdbc:mysql://127.0.0.1:3306/MYDB"/>
- <property name="username" value="root"/>
- <property name="password" value="157891"/>
- </bean>
- <bean id="sqlMapClient" class="org.springframework.orm.ibatis.SqlMapClientFactoryBean">
- <property name="configLocation">
- <value>sqlMapConfig.xml</value>
- </property>
- <property name="dataSource">
- <ref bean="dataSource"/>
- </property>
- </bean>
- <bean id="studentDao" class="com.lanp.dao.StudentDaoImpl">
- <property name="sqlMapClient">
- <ref bean="sqlMapClient"/>
- </property>
- </bean>
- </beans>
9. 测试类,TestStudent:
- package com.lanp.beans;
- import org.springframework.context.ApplicationContext;
- import org.springframework.context.support.ClassPathXmlApplicationContext;
- import com.lanp.dao.StudentDao;
- /**
- * 测试Ibatis
- * @author LanP
- * @since 2011-11-27 15:36
- * @version V1.0
- */
- public class TestStudent {
- public static void main(String[] args) {
- //1.初始化beans.xml文件
- ApplicationContext ctx = new ClassPathXmlApplicationContext("SQLMapClient.xml");
- //2.获取MYDB数据库Student表中的内容
- StudentDao studentDao = (StudentDao)ctx.getBean("studentDao");
- if(null != studentDao) {
- Student student = studentDao.getStudent("ph");
- if(null != student) {
- System.out.println("== 学生名字:" + student.getName() + ",学生密码:" + student.getPsw());
- } else {
- System.out.println("== 没有该学生信息!");
- }
- } else {
- System.out.println("== StudentDao注入失败!");
- }
- }
- }
