SpringBoot AOP 出现 BeanNotOfRequiredTypeException异常怎么办?

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.$Proxy62' at org.springframework.beans.factory.annotation.AutowiredAnnotationBeanPostProcessor$AutowiredFieldElement.inject(AutowiredAnnotationBeanPostProcessor.java:588) at org.springframework.beans.factory.annotation.InjectionMetadata.inject(InjectionMetadata.java:88) at org.springframework.beans.factory.annotation.AutowiredAnnotationBeanPostProcessor.postProcessPropertyValues(AutowiredAnnotationBeanPostProcessor.java:366) at org.springframework.beans.factory.support.AbstractAutowireCapableBeanFactory.populateBean(AbstractAutowireCapableBeanFactory.java:1264) at org.springframework.beans.factory.support.AbstractAutowireCapableBeanFactory.autowireBeanProperties(AbstractAutowireCapableBeanFactory.java:386) at org.springframework.test.context.support.DependencyInjectionTestExecutionListener.injectDependencies(DependencyInjectionTestExecutionListener.java:118) at org.springframework.test.context.support.DependencyInjectionTestExecutionListener.prepareTestInstance(DependencyInjectionTestExecutionListener.java:83) at org.springframework.boot.test.autoconfigure.SpringBootDependencyInjectionTestExecutionListener.prepareTestInstance(SpringBootDependencyInjectionTestExecutionListener.java:44) at org.springframework.test.context.TestContextManager.prepareTestInstance(TestContextManager.java:230) at org.springframework.test.context.junit4.SpringJUnit4ClassRunner.createTest(SpringJUnit4ClassRunner.java:228) at org.springframework.test.context.junit4.SpringJUnit4ClassRunner$1.runReflectiveCall(SpringJUnit4ClassRunner.java:287) at org.junit.internal.runners.model.ReflectiveCallable.run(ReflectiveCallable.java:12) at org.springframework.test.context.junit4.SpringJUnit4ClassRunner.methodBlock(SpringJUnit4ClassRunner.java:289) at org.springframework.test.context.junit4.SpringJUnit4ClassRunner.runChild(SpringJUnit4ClassRunner.java:247) at org.springframework.test.context.junit4.SpringJUnit4ClassRunner.runChild(SpringJUnit4ClassRunner.java:94) at org.junit.runners.ParentRunner$3.run(ParentRunner.java:290) at org.junit.runners.ParentRunner$1.schedule(ParentRunner.java:71) at org.junit.runners.ParentRunner.runChildren(ParentRunner.java:288) at org.junit.runners.ParentRunner.access$000(ParentRunner.java:58) at org.junit.runners.ParentRunner$2.evaluate(ParentRunner.java:268) at org.springframework.test.context.junit4.statements.RunBeforeTestClassCallbacks.evaluate(RunBeforeTestClassCallbacks.java:61) at org.springframework.test.context.junit4.statements.RunAfterTestClassCallbacks.evaluate(RunAfterTestClassCallbacks.java:70) at org.junit.runners.ParentRunner.run(ParentRunner.java:363) at org.springframework.test.context.junit4.SpringJUnit4ClassRunner.run(SpringJUnit4ClassRunner.java:191) at org.junit.runner.JUnitCore.run(JUnitCore.java:137) at com.intellij.junit4.JUnit4IdeaTestRunner.startRunnerWithArgs(JUnit4IdeaTestRunner.java:68) at com.intellij.rt.execution.junit.IdeaTestRunner$Repeater.startRunnerWithArgs(IdeaTestRunner.java:47) at com.intellij.rt.execution.junit.JUnitStarter.prepareStreamsAndStart(JUnitStarter.java:242) at com.intellij.rt.execution.junit.JUnitStarter.main(JUnitStarter.java:70) 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.$Proxy62' at org.springframework.beans.factory.support.DefaultListableBeanFactory.checkBeanNotOfRequiredType(DefaultListableBeanFactory.java:1510) at org.springframework.beans.factory.support.DefaultListableBeanFactory.raiseNoMatchingBeanFound(DefaultListableBeanFactory.java:1489) at org.springframework.beans.factory.support.DefaultListableBeanFactory.doResolveDependency(DefaultListableBeanFactory.java:1104) at org.springframework.beans.factory.support.DefaultListableBeanFactory.resolveDependency(DefaultListableBeanFactory.java:1066) at org.springframework.beans.factory.annotation.AutowiredAnnotationBeanPostProcessor$AutowiredFieldElement.inject(AutowiredAnnotationBeanPostProcessor.java:585) ... 28 more

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;
