ibatis in Spring（簡(jiǎn)單配置）

           （實(shí)現(xiàn)Spring與ibaties的簡(jiǎn)單）

這里我們重點(diǎn)探討Spring框架下的ibatis應(yīng)用，特別是在容器事務(wù)管理模式下的ibatis應(yīng)用開發(fā)。針對(duì)ibatis，Spring配置文件如下：

1、Ibatis-Context.xml:

(下面我將對(duì)本文檔進(jìn)行詳細(xì)說明)

<?xml version="1.0" encoding="UTF-8"?>

<!DOCTYPE beans PUBLIC "-//SPRING//DTD BEAN//EN"

"http://www.springframework.org/dtd/spring-beans.dtd">

<beans>    

 <bean id="dataSource"  這個(gè)節(jié)點(diǎn)不用介紹了

   class="org.apache.commons.dbcp.BasicDataSource"

   destroy-method="close">

   <property name="driverClassName">

     <value>net.sourceforge.jtds.jdbc.Driver</value>

   </property>

   <property name="url">

     <value>jdbc:jtds:sqlserver://127.0.0.1:1433/Sample</value>

   </property>

   <property name="username">

     <value>test</value>

   </property>

   <property name="password">

     <value>changeit</value>

   </property>

 </bean>

這里的sqlMapClient節(jié)點(diǎn)實(shí)際上配置了一個(gè)sqlMapClient的創(chuàng)

建工廠類。 configLocation

屬性配置了ibatis映射文件的名稱。

 <beanid="sqlMapClient"           class="org.springframework.orm.ibatis.SqlMapClientFactoryBean">

 <property name="configLocation">        <value>SqlMapConfig.xml</value>

   </property>

 </bean>

transactionManager節(jié)點(diǎn), 這里我們的transactionManager配置與之前JDBC示例中相同，都采用了DataSourceTransactionManager

<bean id="transactionManager" 

class="org.springframework.jdbc.datasource.DataSourceTransactio

nManager">

        <property name="dataSource"><ref

local="dataSource"/></property>

    </bean>

 userDAO節(jié)點(diǎn)

對(duì)應(yīng)的，UserDAO需要配置兩個(gè)屬性，sqlMapClient和DataSource，

sqlMapClient將從指定的DataSource中獲取數(shù)據(jù)庫(kù)連接。

 <bean id="userDAO" class="net.xiaxin.dao.UserDAO">

   <property name="dataSource">

     <ref local="dataSource" />

   </property>

   <property name="sqlMapClient">

     <ref local="sqlMapClient" />

   </property>

 </bean>

下面是事務(wù)管理

 <bean id="userDAOProxy"

 class="org.springframework.transaction.interceptor.TransactionPro

xyFactoryBean">

   <property name="transactionManager">

     <ref bean="transactionManager" />

   </property>

   <property name="target">

     <ref local="userDAO" />

   </property>

   <property name="transactionAttributes">

     <props>

       <prop key="insert*">PROPAGATION_REQUIRED</prop>

       <prop key="get*">PROPAGATION_REQUIRED,readOnly</prop>

     </props>

   </property>

 </bean>

</beans>

2、sqlMapConfig.xml:

<sqlMapConfig>

 <sqlMap resource="net/xiaxin/dao/entity/user.xml"/>

</sqlMapConfig>

3、net/xiaxin/dao/entity/user .xml

<sqlMap namespace="User">

 <typeAlias alias="user" type="net.xiaxin.dao.entity.User" />

 <insert id="insertUser" parameterClass="user">

    INSERT INTO users ( username, password) VALUES ( #username#,

#password# )

 </insert>

 </sqlMap>

4、UserDAO.java

public class UserDAO extends SqlMapClientDaoSupport implements

IUserDAO {

 public void insertUser(User user) {

    getSqlMapClientTemplate().update("insertUser", user);

 }

}

5、User .java

public class User {

 public Integer id;

 public String username; public String password;

public Integer getId() {

   return id;

}

public void setId(Integer id) {

   this.id = id;

}

public String getPassword() {

   return password;

}

public void setPassword(String password) {

   this.password = password;

}

public String getUsername() {

   return username;

}

public void setUsername(String username) {

   this.username = username;

}

｝

扼要

６、測(cè)試代碼

InputStream is = new FileInputStream("Ibatis-Context.xml");

XmlBeanFactory factory = new XmlBeanFactory(is);

IUserDAO userdao = (IUserDAO)factory.getBean("userDAOProxy");

User user = new User();

user.setUsername("Sofia");

user.setPassword("mypass");

userdao.insertUser(user);
