Spring2事务管理的两种配置(XML&标注

package com.epeer.dao;public interface UserDao {public void insertUserIp(String startip, String endip);} 

package com.epeer.dao;import java.text.MessageFormat;import org.springframework.jdbc.core.support.JdbcDaoSupport;public class UserDaoImpl extends JdbcDaoSupport implements UserDao {private static final String INSERT = "insert into ipsegment(is_id, endip, startip) values(ipsegment_seq.nextval,''{0}'',''{1}'')";public void insertUserIp(String startip, String endip) {getJdbcTemplate().execute(MessageFormat.format(INSERT, new Object[] { startip, endip }));}} 

package com.epeer.service;public interface UserService {public void insertUserIp(String startip, String endip);} 

package com.epeer.service;import org.springframework.transaction.annotation.Transactional;import com.epeer.dao.UserDao;public class UserServiceImpl implements UserService {private UserDao userDao;public UserDao getUserDao() {return userDao;}public void setUserDao(UserDao userDao) {this.userDao = userDao;}public void insertUserIp(String startip, String endip) {userDao.insertUserIp("192.168.0.3", "0.0.0.0");}}

采用标注的话UserServiceImpl如下：

package com.epeer.service;import org.springframework.transaction.annotation.Transactional;import com.epeer.dao.UserDao;@Transactionalpublic class UserServiceImpl implements UserService {private UserDao userDao;public UserDao getUserDao() {return userDao;}public void setUserDao(UserDao userDao) {this.userDao = userDao;}@Transactional(noRollbackForClassName = "java.lang.Throwable")public void insertUserIp(String startip, String endip) {userDao.insertUserIp("192.168.0.3", "0.0.0.0");}}
