spring和mybatis整合遇到org.springframework.beans.factory.BeanDefinitionStoreException

今天对spring和mybatis整合进行练习，通过MapperScannerConfigurer进行mapper扫描

但是在进行单元测试的时候，死活就是报错，具体报错如下：

org.springframework.beans.factory.BeanDefinitionStoreException: Failed to read candidate component class: file [G:\idea_file\Spring_MyBatis\out\production\Spring_MyBatis\com\company\ssm\mapper\UserMapper.class]; nested exception is java.lang.IllegalArgumentException

刚开始我也很纳闷，后来到网上看了一下，原来是jdk版本(1.80)和整合包(mybatis-spring-1.2.2.jar)的版本不兼容

解决方法1：替换整合jar包为更高版本的jar,如4.2.6的jar包【有兴趣的同学可以自己替换下】

解决方法2：把jdk的版本更换为1.7【因为我的电脑上同时安装了jdk1.7和jdk1.8，所以我就直接替换为jdk1.7，问题就解决了】
