业务层接口
package com.cxx.service;
import com.cxx.pojo.Users;
public interface UsersService {
void insertUsers(Users users);

业务层接口实现类
package com.cxx.service.impl;
import com.cxx.dao.UsersDao;

}
@Override
public void insertUsers(Users users) {

测试类
package com.cxx.test;
import com.cxx.pojo.Users;
import com.cxx.service.UsersService;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;
public class AddUsersTest {
public static void main(String[] args) {
ApplicationContext applicationContext = new ClassPathXmlApplicationContext("applicationContext.xml");
UsersService usersService = (UsersService) applicationContext.getBean("usersService");
Users users = new Users();
users.setUsername("老吴");
users.setUsersex("男");
usersService.insertUsers(users);
}
}
这里跟视频做的不一样,持久层和业务层分离做的,,,但是运行报错:

分析了半小时左右,去掉了spring配置文件中的配置别名 运行成功,为什么这里别名会引起报错??
<!--配置SqlSessionFactoryBean-->
<bean id="sqlSessionFactoryBean" class="org.mybatis.spring.SqlSessionFactoryBean">
<property name="dataSource" ref="dataSource1"/>
<!--配置别名-->
<!--<property name="transactionFactory" value="com.cxx.pojo"/>-->
<!--引入mapper的配置文件-->
<property name="mapperLocations" value="com/cxx/mapper/*.xml"/>
</bean>
去掉反而正常了呢?
老师我的这个环境变量，应该往哪里加呢。视频里老师不是说系统的Path里加吗。
请问老师，输入指令它就显示系统发生错误5 。拒绝访问。这应该怎么解决
请问老师，我画圈的地方没有多余的选项。我看视频里的老师有选项，把Development Components这个选项去掉了
