MyBatis与Spring整合细节的优化  
整合过程参考：[http://blog.csdn.net/leisure\_life/article/details/72778179][http_blog.csdn.net_leisure_life_article_details_72778179]  
优化部分：spring中配置接口扫描

<bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
                
                <property name="basePackage" value="com.hl.ld.mapper"/>
                <property name="sqlSessionFactoryBeanName" value="sqlSessionFactory"/>
            </bean>

测试：优化部分，接口的id为接口名首字母小写

package com.hl.ld.test;
    
    import org.junit.Before;
    import org.junit.Test;
    import org.springframework.context.ApplicationContext;
    import org.springframework.context.support.ClassPathXmlApplicationContext;
    
    import com.hl.ld.mapper.UserMapper;
    import com.hl.ld.pojo.User;
    
    
    public class SpringMybatisTest {
        private ApplicationContext applicationContext;
    
        @Before
        public void before(){
            String configLocation = "classpath:spring/applicationContext.xml";
            //获取spring容器
            applicationContext = new ClassPathXmlApplicationContext(configLocation);
        }
        @Test
        public void testFindUserById() throws Exception{
            UserMapper userMaper = (UserMapper) applicationContext.getBean("userMapper");
            User user = userMaper.findUserById(3);
            System.out.println(user);
        }
    }
