今天在做ssh项目的时候，遇到了个问题，解决了半天，很是头疼，终于解决了，分享出来给大家都看看解决方法。

 错误如下：

java.lang.ClassCastException: com.sun.proxy.$Proxy6 cannot be cast to org.service.impl.EmpServiceImpl

相关代码如下：

private IEmpService empService;
	
	@Before
	public void init(){
		ApplicationContext applicationContext = new ClassPathXmlApplicationContext("applicationContext.xml");
		empService = (EmpServiceImpl)applicationContext.getBean("empService");
	}

改为：

private IEmpService empService;
	
	@Before
	public void init(){
		ApplicationContext applicationContext = new ClassPathXmlApplicationContext("applicationContext.xml");
		empService = (IEmpService)applicationContext.getBean("empService");
	}

简单的来说是将   EmpServiceImpl 改为IEmpService就OK，一定得仔细！
