小案例基本思路是: 我们在 MyBatisTest.java 中进行单元测试,单元测试中调用dao层实现类UserDaoImpl中的方法。...在 UserDaoImpl.java 中运用我们手写的mybatis工具类进行获取sqlsession,执行映射文件中的sql,并把查询结果返回MyBatisTest.java中的调用方法以输出显示。...key 就是下方 MyBatisTest.java 文件中的map.put("password",value)的第一个参数。...MyBatisTest.java: public class MybatisTest { UserDao userDao = null; @Before public void init(){ userDao

2 自定义MyBatis 在入门实战案例基础上修改,删除掉pom.xml中MyBatis的坐标,下面按步骤搞起: 2.1 根据MyBatisTest测试类中缺少的创建接口和类 MyBatisTest测试类中涉及的类如下...,我们需要自定义,先创建,让MyBatisTest测试类不报错,然后再下一步中填充内容: Class Resources Class SqlSessionFactoryBuilder Interface... SqlSessionFactory Interface SqlSession 为了便于观察,将MyBatisTest中的代码贴一下,整体实现思路就是如下注释的: public class MyBatisTest
import org.apache.ibatis.session.SqlSessionFactoryBuilder; import com.mytest.beans.User; public class MyBatisTest...String resource = "mybatis_config.xml"; // com.mysql.jdbc.Driver InputStream is = MyBatisTest.class.getClassLoader

(4)创建测试类MyBatisTest 在io.binghe.mybatis.test包中创建测试程序的入口类MyBatisTest,如下所示。...java.io.InputStream; /** * @author binghe * @version 1.0.0 * @description 测试用例的入口类 */ @Slf4j public class MyBatisTest...UserMapper.class); User user = userMapper.selectUser(1); log.info(user.toString()); } } 在MyBatisTest...`t_user` (`id`, `username`, `age`) VALUES ('4', 'lisi', '19'); 三、运行测试用例 运行MyBatisTest类中的testXml()方法,输出结果如下所示
SqlMapConfig.xml; 5,配置文件UserDao.xml; 6,配置文件log4j.properties; 7,domain.User.java; 8,UserDao.java接口; 9,写测试程序MybatisTest.java...address; 8,UserDao.java接口: public interface UserDao { // 查询所有接口: List findAll(); } 9,写测试程序MybatisTest.java...: public class MybatisTest { public static void main(String[] args)throws Exception { //
的测试类(com.itweb.test.MyBatisTest),如下4、安装MyBatisX插件MybatisX是一款基于IDEA的快速开发插件,为效率而生。...resultMap="brandResultMap"> select * from tb_brand where id = #{id}; 3)编写测试用例并执行方法在MyBatisTest... selectByCondition(Brand brand); List selectByCondition(Map map);3)编写测试用例并执行方法在MyBatisTest...#{brandName} 3)编写测试用例并执行方法在MyBatisTest...values (#{brandName},#{companyName},#{ordered},#{description},#{status}); 3)编写测试用例并执行方法在MyBatisTest
