Question

spring-ibatis怎样通过点击button向数据库添加数据csdn

Answer 1

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 print?
#############################################################################################
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

[java] view plain copy print?
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：

[html] view plain copy print?
<?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：

[java] view plain copy print?
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：

[java] view plain copy print?
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：

[html] view plain copy print?
<?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：

[html] view plain copy print?
<?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：

[java] view plain copy print?
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！");
}

}

}

OK,TKS!
