Question

当我添加注释@EnableAspectJAutoProxy时，我的项目将无法加载applicationcontext.But如果我删除@EnableAspectJAutoProxy，将不会发生异常。当然，如果我删除它，AOP不起作用。我使用spring3和junit4在我的app.Here是一些代码片段：

我的配置类：

import org.springframework.context.annotation.ComponentScan;
import org.springframework.context.annotation.Configuration;
import org.springframework.context.annotation.EnableAspectJAutoProxy;
@Configuration
@EnableAspectJAutoProxy
@ComponentScan(basePackages = { "com.*" })
public class CenterConfigration
{}

我的测试代码：

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(classes = CenterConfigration.class)
public class CenterTest
{
@Autowired
private BeanTest beanTest;

@Test
public void test()
{
    System.out.println(beanTest.name);
    System.out.println(beanTest.value);
    System.out.println("--------");
    beanTest.print();
}

我的方面代码：

import java.lang.reflect.Method;
import org.aspectj.lang.ProceedingJoinPoint;
import org.aspectj.lang.annotation.Around;
import org.aspectj.lang.annotation.Aspect;
import org.springframework.stereotype.Component;
@Component
@Aspect
public class PNNAspectHandler
{
@Around("@annotation(com.judex.annotation.ParamNotNull)")
public Object validatePNN(ProceedingJoinPoint proceedingJoinPoint) throws Throwable
{
    System.out.println("check begin...");
    Method method = null;
    Object[] method_args = null;
    Object target = null;
    String method_name = null;

    target = proceedingJoinPoint.getTarget();
    method_name = proceedingJoinPoint.getSignature().getName();
    method = getSpecMethodByClassName(target.getClass(), method_name);
    System.out.println(method.getName());
    method_args = proceedingJoinPoint.getArgs();
    boolean validateResult = validateArgs(method_args);
    if (validateResult)
    {
        return proceedingJoinPoint.proceed();
    } else
    {
        throw new RuntimeException("method:" + method_name + "err!");
    }

}

public boolean validateArgs(Object[] method_args)
{
    for (Object object : method_args)
    {
        if (object == null || "".equals(object.toString()))
        {
            return false;
        }
    }
    return true;
}

public Method getSpecMethodByClassName(Class<?> clazz, String method_name)
{
    Method[] methods = clazz.getDeclaredMethods();
    for (Method method : methods)
    {
        method.setAccessible(true);
        if (method.getName().equals(method_name))
        {
            return method;
        }
    }

    return null;
}
}

如果我添加@ EnableAspectJAutoProxy，会发生一些异常，这里有一些关于例外的信息。
