mybatis+spring报错求指点（已解决）

错误简述

• 我在mybatis环境下能够运行，但当我整合了spring后，出现了错误
• 当我使用单个接口映射时又能成功运行
• 所以，问题出在批量加载mapper上

解决方法一（不推荐）

既然问题出在批量加载上，那么，我们可以使用单个加载的方式

<!-- mapper配置 
MapperFactoryBean：根据mapper接口生成代理对象
-->
<bean id="userMapper" class="org.mybatis.spring.mapper.MapperFactoryBean">
		<!-- mapperInterface指定mapper接口 -->
		<property name="mapperInterface" value="com.mapper.UserMapper"/>
		<property name="sqlSessionFactory" ref="sqlSessionFactory"/>
</bean>

解决方法二（从根本上解决）

经过查找多方面资料，发现这是很多人困扰的问题，在我看源码的时候，不知道是与jdk版本还是什么东西的版本不匹配的原因或是jar包的原因，有些字段的set方法没法调用了。

也就是说，批量加载的时候，我们的配置，根本就没有写进去

具体实现

• 既然知道了这个原因，我们需要下载较新版本的相关jar包。但是这种方法很难可行，因为jar包实在难找（大家懂的）
• 通过这件事我也简单的学习了一下maven，用maven添加依赖jar包还是相较容易的，在经过了简单地学习之后，可以使用批量加载了，具体用maven怎么弄，后续的帖子里面会详细说明
