 xml顶部需要加上：xmlns:tx=http://www.springframework.org/schema/tx

xsi:schemaLocation="http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx.xsd" 支持事务。

AccountServiceImpl.java

package org.zlex.spring.service.impl;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
import org.springframework.transaction.annotation.Transactional;
import org.zlex.spring.dao.AccountDao;
import org.zlex.spring.domain.Account;
import org.zlex.spring.service.AccountService;

@Service
@Transactional
public class AccountServiceImpl implements AccountService {

	@Autowired
	private AccountDao accountDao;
	
	public boolean verify(String username, String password) {
		
		Account account = accountDao.read(username);
		if (password.equals(account.getPassword())) {
			return true;
		} else {
			return false;
		}
	}

}

 jdbc.properties

#mysql configuration
jdbc.mysql.className = com.mysql.jdbc.Driver
jdbc.mysql.url = jdbc:mysql://localhost:3306/sms
jdbc.mysql.user = test
jdbc.mysql.password = test
jdbc.mysql.dialect = org.hibernate.dialect.MySQL5Dialect

 

支持jar包~!

cglib-nodep-2.1_3.jar

commons-dbcp.jar

commons-pool.jar

mysql-connector-java-3.1.11.jar 并启动mysql服务~!

Spring2.5注解事务说明~!

1. 如果事务管理器的id是transactionManger，这里可以不对transaction-manager进行配置，即<tx:annotation-driven />就可以了。
2. 这个配置是告诉spring在类（接口）层面或者方法层面上检查应用程序上下文中的所有标准了@Transactional的bean，spring将自动把事务通知的内容通知给它。
3. 这个通知的事务参数将由@Transactional注释的参数来定义
4. 如果注释的是接口，则该接口的所有实现类都将被事务化。
