弹簧自动装配不能与代理

Question

这里是我的弹簧配置文件和类： -

我不能自动测试服务中的代理类。运行Test.java后，我得到NullPointerException，明显属性'arthmeticCalculator'没有设置。

我没有得到什么问题？请帮我解决这个问题。

<bean id="arthmeticCalculator" class="com.manoj.aop.test.CalculatorImpl"/> 
<bean class="org.springframework.aop.framework.autoproxy.BeanNameAutoProxyCreator"> 
    <property name="beanNames"> 
     <list> 
     <value>*Calculator</value> 
     </list> 
    </property> 
    <property name="interceptorNames"> 
     <list> 
     <value>methodNameAdvisor</value> 
     </list> 
    </property> 
</bean> 
<bean id="methodNameAdvisor" class="org.springframework.aop.support.NameMatchMethodPointcutAdvisor"> 
    <property name="mappedNames"> 
     <list> 
      <value>add</value> 
      <value>sub</value> 
     </list> 
    </property> 
    <property name="advice" ref="loggingAroundAdvice" /> 
</bean> 
<bean id="loggingAroundAdvice" class="com.manoj.aop.test.LoggingAroundAdvice"/> 
<bean id="testService" class="com.manoj.aop.test.TestService"> 

</bean> 

Calculator.java:-

public interface Calculator { 

    public double add(double a,double b); 
} 

CacculatorImpl： -

public class CalculatorImpl implements Calculator { 

    public double add(double a, double b) { 
     return a+b; 
    }  
} 

LoggingAroundAdvice： -

public class LoggingAroundAdvice implements MethodInterceptor{ 


    public Object invoke(MethodInvocation methodInvocation) throws Throwable { 
     System.out.println("Around Invoice called"); 
     Object result = methodInvocation.proceed(); 
     return result; 
    } 

} 

TestService的： -

public class TestService { 

    @Autowired 
    private Calculator arthmeticCalculator; 


    public void test(){ 
     System.out.println(arthmeticCalculator.add(5, 10.5)); 
    } 
} 

Test.java:-

public class Test {  
    /** 
    * @param args 
    */ 
    public static void main(String[] args) { 
     ApplicationContext context = new ClassPathXmlApplicationContext("com/manoj/aop/test/aop.xml"); 
     TestService service = (TestService) context.getBean("testService"); 
     service.test(); 
    } 
} 

Answer 1

是否无代理工作？可能需要<context:annotation-config/>。

Answer 2

您没有包含您的所有配置。自动装配由BeanPostProcessor完成http://static.springsource.org/spring/docs/3.0.x/javadoc-api/org/springframework/beans/factory/annotation/AutowiredAnnotationBeanPostProcessor.html

您可以通过<context:annotation-config/>启用此功能。
