spring数据源的注入、JdbcTemplate管理、编程式的事务管理DataSourceTransactionManager
(2)、如果采用的是JNDI连接，可以这么设定：
<bean id="dataSource"
encoding="UTF-8"?>
<!DOCTYPE beans PUBLIC "-//SPRING/DTD BEAN/EN" "http://www.springframework.org/dtd/spring-beans.dtd">
<beans>
<bean id="dataSource" class="onlyfun.caterpillar.UserDAO">
<property name="dataSource">
<ref bean="dataSource"/>
</property>
<property name="transactionManager">
<ref bean="transactionManager"/>
</property>
</bean>
</beans>
DAO操作类：
package onlyfun.caterpillar;
import javax.sql.DataSource;
import org.springframework.jdbc.core.*;
import org.springframework.transaction.*;
import org.springframework.transaction.support.*;
import org.springframework.dao.*;
public class UserDAO {
private DataSource dataSource;
private PlatformTransactionManager transactionManager;
public void setDataSource(DataSource dataSource) {
this.dataSource = dataSource;
}
public void setTransactionManager(PlatformTransactionManager transactionManager) {
this.transactionManager = transactionManager;
}
public void insertUser(User user) {
DefaultTransactionDefinition def = new DefaultTransactionDefinition();
TransactionStatus status = transactionManager.getTransaction(def);
try {
JdbcTemplate jdbcTemplate = new JdbcTemplate(dataSource);
jdbcTemplate.update("INSERT INTO USER VALUES('Spring008', 'caterpillar', 'M', 29)");
jdbcTemplate.update("INSERT INTO USER VALUES('Spring009', 'momor', 'F', 26)");
jdbcTemplate.update("INSERT INTO USER VALUES('Spring010, 'beckyday', 'F', 35)");
} catch (DataAccessException ex) {
transactionManager.rollback(status); // 也可以執行status.setRollbackOnly();
throw ex;
}
transactionManager.commit(status);
}
}
