用jdbc操作数据库的简单例子(三)
o;
import cn.csdn.web.dao.UsersDaoImpl;
import cn.csdn.web.domain.Users;
public class UsersTest {
UsersDao uDao = new UsersDaoImpl();
@Test
public void insert(){
Users entity = new Users();
entity.setName("测试1");
entity.setPass("123");
entity.setSex("女");
entity.setAge(21);
boolean flag = uDao.insert(entity);
if(flag){
System.out.println("插入成功");
}else{
System.out.println("插入失败");
}
}
@Test
public void findById(){
Users entity = uDao.findById(1);
System.out.println(entity.toString());
}
@Test
public void update(){
Users entity = uDao.findById(4);
entity.setName("测试2");
entity.setAge(20);
boolean flag = uDao.updateById(entity);
if(flag){
System.out.println("更新成功");
}else{
System.out.println("更新失败");
}
}
@Test
public void deleteById(){
boolean flag = uDao.deleteById(27);
if(flag){
System.out.println("删除成功");
}else{
System.out.println("删除失败");
}
}
}
