Spring异常——BeanNotOfRequiredTypeException

使用junit测试ssh搭建的框架的时候，遇到了一个异常：

异常消息：

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'com.htd.test.Test1':
Injection of resource dependencies failed;

nested exception is org.springframework.beans.factory.BeanNotOfRequiredTypeException:
Bean named 'registerService' must be of type [com.htd.service.impl.RegisterServiceImpl],
but was actually of type [com.sun.proxy.$Proxy42]

测试类代码：

 package com.htd.test;

 import javax.annotation.Resource;
 import org.junit.Test;
 import org.junit.runner.RunWith;
 import org.springframework.test.context.ContextConfiguration;
 import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;
 import com.htd.domain.Customer;
 import com.htd.service.impl.RegisterServiceImpl;

 @RunWith(SpringJUnit4ClassRunner.class)
 @ContextConfiguration("classpath:applicationContext.xml")
 public class Test1 {
     @Resource(name="registerService")
     private RegisterServiceImpl registerService;

     @Test
     public void test1() {
         Customer customer=new Customer();
         customer.setCus_name("eastry");
         customer.setCus_email("123456@qq.com");
         customer.setCus_pwd("123");
         customer.setCus_id(1);
         registerService.save(customer);
     }

 }

RegisterServiceImpl类:

 package com.htd.service.impl;

 import org.springframework.transaction.annotation.Transactional;

 import com.htd.dao.impl.CustomerDaoImpl;
 import com.htd.domain.Customer;
 import com.htd.service.IRegisterService;

 @Transactional
 public class RegisterServiceImpl implements IRegisterService {
     //xml方式注入
     private CustomerDaoImpl customerDao;
     public void setCustomerDao(CustomerDaoImpl customerDao) {
         this.customerDao = customerDao;
     }
     @Override
     public void save(Customer customer) {
         customerDao.save(customer);
     }
 }

RegisterServiceImpl的接口IRegisterService:

 import com.htd.domain.Customer;

 public interface IRegisterService {
     public void save(Customer customer);
 }

运行结果:

不好，红了。。。。。

这里没有使用Cglib代理，Java的动态代理是使用接口实现的，但是在Test类里面注入的时候是使用Service的实现类(即：RegisterServiceImpl)注入的，所以这里会出错。

如图：

修改成下列代码测试成功：

修改后的测试类代码：

 import javax.annotation.Resource;

 import org.junit.Test;
 import org.junit.runner.RunWith;
 import org.springframework.test.context.ContextConfiguration;
 import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;

 import com.htd.domain.Customer;
 import com.htd.service.IRegisterService;
 @RunWith(SpringJUnit4ClassRunner.class)
 @ContextConfiguration("classpath:applicationContext.xml")
 public class Test1 {
     @Resource(name="registerService")
     private IRegisterService registerService;

     @Test
     public void test1() {
         Customer customer=new Customer();
         customer.setCus_name("eastry");
         customer.setCus_email("123456@qq.com");
         customer.setCus_pwd("123");
         customer.setCus_id(1);
         registerService.save(customer);
     }
 }

运行结果：

嗯，变绿了，很好。。。。。。。。。。。

如果想用类注入，就要导入Cglib的jar包 使用类来实现代理？？？？请大佬指导，我还没试试，之后会去实验下。
