这是我用Spring整合Mybatis并配置事务时，获取bean时得到的一个错误
Bean named 'xxx' is expected to be of type 'xxx' but was actually of type 'com.sun.proxy.$Proxy19'
这个就是我的Service层
这个是我获取bean的代码，如果第二个参数是CourseService.class的话就没有什么问题，但是因为我在CourseServiceImpl中加了几个方法所以需要用到它的实现类，所以必须获取CourseServiceImpl
CourseServiceImpl courseService = applicationContext.getBean("courseService",CourseServiceImpl.class);
解决方法：
applicationContext.xml里面修改代理模式为proxy-target-class="true"
<tx:annotation-driven transaction-manager="dataSourceTransactionManager" proxy-target-class="true" />
