1、引入相关jar包（版本对应关系3.3.1版本的mybatis和1.1.1的spring-mybatis匹配，3.4.1版本的mybatis和1.3.1的spring-mybatis匹配）

如果不对应会报org.mybatis.spring.transaction.SpringManagedTransaction.getTimeout()类似错误

maven的pom.xml配置如下

          1.3.1

          commons-dbcp

           src/main/java
                          
                              
           
            **/*.xml
                           
                          
          
           false
                      
                 
            
       
      

2、在classpath下创建applicationContext.xml文件，并配置如下

3、测试代码如下

import com.hjp.mapper.UserMapper;import com.hjp.po.User;import org.junit.Before;import org.junit.Test;import org.springframework.context.ApplicationContext;import org.springframework.context.support.ClassPathXmlApplicationContext;public class SpringDemoTest {    private ApplicationContext context;    @Before    public void setUp(){        context=new ClassPathXmlApplicationContext("applicationContext.xml");    }    @Test    public void func1() throws Exception {        UserMapper userMapper= (UserMapper) context.getBean("userMapper");        User user=userMapper.findUserById(1);        System.out.println(user);    }}
