1.我的项目采用 Spring boot 开发.写了一个关于Aop的测试代码,报了如下异常信息:
Caused by: org.springframework.beans.factory.BeanNotOfRequiredTypeException: Bean named 'performanceImpl' is expected to be of type 'com.itguang.demo.aop.PerformanceImpl' but was actually of type 'com.sun.proxy.$Proxy62'
具体代码如下:
一个接口 Performance
public interface Performance {
public void perform();
}
实现类 :PerformanceImpl
/**
* @author itguang
* @create 2017-11-07 8:26
**/
public class PerformanceImpl implements Performance{
@Override
public void perform() {
System.out.println("表演单口相声...");
}
}
切面类:Audience2
/**
* 观看演出的切面
*
* @author itguang
* @create 2017-11-06 16:49
**/
@Aspect
public class Audience2 {
@Pointcut("execution(* com.itguang.demo.aop.Performance.perform(..))")
public void performance(){
}
/**
* 手机静音
*/
@Before("performance()")
public void silenceCellPhone(){
System.out.println("Silence Cell Phone");
}
/**
* 就做
*/
@Before("performance()")
public void takeSeats(){
System.out.println("Taking seats");
}
/**
* 鼓掌
*/
@AfterReturning("performance()")
public void applause(){
System.out.println("pa pa pa");
}
/**
* 表演失败(异常),退款
*/
@AfterThrowing("performance()")
public void demandRefund(){
System.out.println("Demanding a refund");
}
}
配置类: AOPConfig
/**
* AOP config
*
* @author itguang
* @create 2017-11-06 16:53
**/
@Configuration
@EnableAspectJAutoProxy
public class AOPConfig {
@Bean
public Audience2 audience2(){
return new Audience2();
}
@Bean(name = "performanceImpl")
public Performance performanceImpl(){
return new PerformanceImpl();
}
}
上面就是所有代码, 测试类如下:
@RunWith(SpringRunner.class)
@SpringBootTest
public class SpringAopApplicationTests {
@Autowired
private PerformanceImpl performanceImpl;
@Test
public void contextLoads() {
performanceImpl.perform();
}
}
运行报错代码完成如下
org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'com.itguang.demo.SpringAopApplicationTests': Unsatisfied dependency expressed through field 'performanceImpl'; nested exception is org.springframework.beans.factory.BeanNotOfRequiredTypeException: Bean named 'performanceImpl' is expected to be of type 'com.itguang.demo.aop.PerformanceImpl' but was actually of type 'com.sun.proxy.$Proxy62'

如果我不采用接口的代理形式,就可以通过测试,但是基于借口的动态代理救火报错,不知道基于java配置的Spring应该怎样解决?

最后测试代码要使用接口注入。
@Autowired
private PerformanceImpl performanceImpl;
更改为
@Autowired
private Performance performanceImpl;
