15.mybtis_spring_dao(传智播客)

需求:根据用户id查询用户信息

一.配置

1.mybatis.xml

2.applicationContext-dao.xml

二.映射

三.接口以及接口实现类

public interface UserDao {
    User findUserById(int id) throws Exception;
}

public class UserDaoImpl extends SqlSessionDaoSupport implements UserDao{
    @Override
    public User findUserById(int id) throws Exception {
        SqlSession sqlSession = this.getSqlSession();
        User user = sqlSession.selectOne("findUserById",1);
        return user;
    }
}

四.po类编写

public class User {
    //属性名要和数据库表的字段对应
    private int id;
    private String username;// 用户姓名
    private String sex;// 性别
    private String birthday;// 生日
    private String address;// 地址
    //get和set方法......
}

五.测试

ApplicationContext applicationContext = new ClassPathXmlApplicationContext("config/spring/applicationContext-dao.xml");
UserDaoImpl userDaoImpl = (UserDaoImpl) applicationContext.getBean("userDaoImpl");
User user = userDaoImpl.findUserById(1);
System.out.println(user);

运行测试结果如下

JDK1.5 Cyclicbarrier实例 bijian1013 java thread java多线程 Cyclicbarrier
CyclicBarrier类一个同步辅助类，它允许一组线程互相等待，直到到达某个公共屏障点 (common barrier point)。在涉及一组固定大小的线程的程序中，这些线程必须不时地互相等待，此时 CyclicBarrier 很有用。因为该 barrier 在释放等待线程后可以重用，所以称它为循环的 barrier。 CyclicBarrier支持一个可选的 Runnable 命令，

ua实现split字符串分隔 ronin47 lua split
LUA并不象其它许多"大而全"的语言那样，包括很多功能，比如网络通讯、图形界面等。但是LUA可以很容易地被扩展：由宿主语言(通常是C或 C++)提供这些功能，LUA可以使用它们，就像是本来就内置的功能一样。LUA只包括一个精简的核心和最基本的库。这使得LUA体积小、启动速度快，从而适合嵌入在别的程序里。因此在lua中并没有其他语言那样多的系统函数。习惯了其他语言的字符串分割函
