【错误解决】BeanDefinitionStoreException: Failed to read candidate component class: file [mapper.class文件]; nested exception is java.lang.IllegalArgumentException

问题描述：

　　“spring-mybatis整合，使用mapper代理开发，通过MapperScannerConfigurer进行mapper扫描”的练习中，出现异常：

　　org.springframework.beans.factory.BeanDefinitionStoreException: Failed to read candidate component class: file [E:\项目\mybatis_spring\bin\cn\itheima\ssm\mapper\UserMapper.class]; nested exception is java.lang.IllegalArgumentException

问题分析:

　　我使用的spring是3.2版本的，而编译器是jdk1.8，根据spring官网的说法，要使用java8，只支持spring 4.X以上版本，而spring的使用最低java要求java5及以上，也就是说spring与编译器版本不匹配

问题解决：

　　将项目使用的编译器改为1.7版本：

　　选中项目右键->properties
