package test.dao;


import org.junit.Test;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;

import cn.tedu.cloud_note.dao.UserDao;
import cn.tedu.cloud_note.entity.User;

public class UserDaoTest {
  @Test
  public void  testUserDao() {
    ApplicationContext ctx=
        new ClassPathXmlApplicationContext("conf/spring-mybatis.xml");
    UserDao dao=ctx.getBean("userDao",UserDao.class);
    User user=dao.findByName("demo");
    System.out.println("user:"+user);
  }
  
  @Test
  public void testSave(){
    String[] conf={"/conf/spring-mybatis.xml",
          "/conf/spring-mvc.xml"};
    //实例化ctx对象
    ApplicationContext ctx=
        new ClassPathXmlApplicationContext(conf);
    //获取UserDao对象
    UserDao dao=ctx.getBean("userDao",UserDao.class);
    User user=new User();
    user.setCn_user_id("1465778979");
    user.setCn_user_name("烤鸭");
    user.setCn_user_password("123456");
    user.setCn_user_desc("烤鱼");
    
    //通过dao执行sava方法
    dao.save(user);
    System.out.println(user);
  }
  
}










新人小白求问:为什么在ctx的代码中不能传入conf属性,传入的话就会报错

但是用这个就不报错。。。。

 @Test
  public void testSave(){
    /*String[] conf={"conf/spring-mybatis.xml",
          "conf/spring-mvc.xml"};*/
    //实例化ctx对象
    ApplicationContext ctx=
        new ClassPathXmlApplicationContext("conf/spring-mybatis.xml");
