在Spring和mybatis进行整合进行单元测试时，遇到如下报错：

org.springframework.beans.factory.BeanDefinitionStoreException: Failed to read candidate component class: file [E:\MyEclipse 2017 CI\workspace\spring_mybatis1\bin\cn\wang\ssm\mapper\UserMapper.class]; nested exception is java.lang.IllegalArgumentException

报错原因：工程的JDK版本和spring的Jar包不兼容，JDK1.8，spring的jar包是3.2，应该是4.2.6；
解决方法：下载4.2.6版本的spring的jar包，将4.2.6的jar包加入到工程的lib中，然后将关于spring3.2.0的jar包全部删除掉（remove）。
spring官网下载spring jar包的方法：www.spring.io
