使用IOC（控制反轉）技術容器全權負責的組件的裝配，它會把符合依賴關系的對象通過JavaBean屬性或者構造函數傳遞給需要的對象。
一.建立數據庫database,表明tb_user
CREATE TABLE `tb_user` (
? `id` int(10) unsigned NOT NULL AUTO_INCREMENT,
? `name` varchar(45) NOT NULL,
? `age` int(10) unsigned NOT NULL,
? `sex` varchar(45) NOT NULL,
? PRIMARY KEY (`id`)
)
二、建立在src下建立包并建立applicationContext.xml
1.main包
1.1建立Manager.java
2.transaction
2.1TransactionExample.java
三在WEB-INF下的lib導入jar包
1.aopalliance.jar（這個包是AOP聯盟的API包，里面包含了針對面向切面的接口。）
2.commons-logging.jar（Commons Logging (JCL)提供的是一個日志(Log)接口(interface)，同時兼顧輕量級和不依賴于具體的日志實現工具。）
3.mysql-connector-java-5.1.20-bin.jar
4.org.springframework.asm-3.1.1.RELEASE.jar
5.org.springframework.beans-3.1.1.RELEASE.jar（Spring IoC的基礎的實現）
6.org.springframework.core-3.1.1.RELEASE.jar（Spring 的核心模塊）
7.org.springframework.jdbc-3.1.1.RELEASE.jar（Spring 的JDBC模塊）
8.org.springframework.transaction-3.1.1.RELEASE.jar
四、以下是程序
Manager.java
package com.mr.main;
import org.springframework.beans.factory.BeanFactory;
import org.springframework.beans.factory.xml.XmlBeanFactory;
import org.springframework.core.io.ClassPathResource;
import org.springframework.core.io.Resource;
import com.mr.transaction.TransactionExample;
public class Manager {
public static void main(String[] args) {
Resource resource =new ClassPathResource("applicationContext.xml");//裝載配置文件
? ? ? ? BeanFactory factory =new XmlBeanFactory(resource);
TransactionExample transactionExample = (TransactionExample) factory.getBean("transactionExample");//獲取UserDAO
? ? ? ? transactionExample.transactionOperation();//執行添加方法
? ? }
}
2.TransactionExample.java
package com.mr.transaction;
import org.springframework.jdbc.datasource.DataSourceUtils;
import org.springframework.transaction.PlatformTransactionManager;
import org.springframework.transaction.TransactionStatus;
import org.springframework.transaction.support.TransactionCallback;
import org.springframework.transaction.support.TransactionTemplate;
import javax.sql.DataSource;
import java.sql.Connection;
import java.sql.Statement;
public class TransactionExample {
DataSourcedataSource;//注入數據源
? ? PlatformTransactionManagertransactionManager;//注入事務管理器
? ? TransactionTemplatetransactionTemplate;//注入TransactionTemplate模板
? ? public DataSource getDataSource() {
return dataSource;
}
public void setDataSource(DataSource dataSource) {
this.dataSource = dataSource;
}
public PlatformTransactionManager getTransactionManager() {
return transactionManager;
}
public void setTransactionManager(PlatformTransactionManager transactionManager) {
this.transactionManager = transactionManager;
}
public TransactionTemplate getTransactionTemplate() {
return transactionTemplate;
}
public void setTransactionTemplate(TransactionTemplate transactionTemplate) {
this.transactionTemplate = transactionTemplate;
}
public void transactionOperation() {
transactionTemplate.execute(new TransactionCallback() {
public Object doInTransaction(TransactionStatus status) {
Connection conn = DataSourceUtils.getConnection(dataSource);//獲得數據庫連接
? ? ? ? ? ? ? ? try {
Statement stmt = conn.createStatement();
//執行兩次添加方法
? ? ? ? ? ? ? ? ? ? stmt.execute("insert into tb_user(name,age,sex) values('小強','26','男')");
stmt.execute("insert into tb_user(name,age,sex) values('小紅','22','女')");
System.out.println("操作執行成功！");
}catch (Exception e) {
transactionManager.rollback(status);//事務回滾
? ? ? ? ? ? ? ? ? ? System.out.println("操作執行失敗，事務回滾！");
System.out.println("原因："+e.getMessage());
}
return null;
}
});
}
}
3.applicationContext.xml
? xmlns="http://www.springframework.org/schema/beans"
? xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
? xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.5.xsd">
<!--配置數據源-->
<beans>
<bean id="database"
class="org.springframework.jdbc.datasource.DriverManagerDataSource">
<property name="driverClassName" value="com.mysql.jdbc.Driver"/>
<property name="url" value=" jdbc:mysql://localhost:3306/db_database17"/>
<property name="username" value="root"/>
<property name="password" value="密碼" />
</bean>
<!--定義TransactionTemplate模板 -->
<bean id="transactionTemplate" class="org.springframework.transaction.support.TransactionTemplate">
<property name="transactionManager" ref bean="transactionManager"/>
<property? name="propagationBehaviorName" value="PROPAGATION_REQUIRED"/>
</bean>
<!--定義事務管理器-->
<bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
<property name="dataSource" ref bean="dataSource"/>
</bean>
<!--為TransactionExample注入數據源 、事務管理器、TransactionTemplate模板-->
<bean id="transactionTemplate" class="org.springframework.transaction.support.TransactionTemplate">
<property name="dataSource" ref bean="dataSource"/>
<property name="transactionManager" ref bean="transactionManager" />
<property name="transactionTemplate" ref bean="transactionTemplate"/>
</bean>
</beans>
五、運行結果
