Spring2事务管理的两种配置(XML&&标注)-转载-优快云博客

本文介绍了一个使用Spring框架实现的简单应用程序，该应用通过接口定义了插入用户IP段的功能，并展示了如何利用Spring的声明式事务管理和基于注解的事务控制来确保数据库操作的一致性和可靠性。

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;
    }

        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;

@Transactional

public 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");

}
