XFire序

1、上篇中关于Jsr181HandlerMapping分析。

 红箭头中指代的就是上篇中注入的三个参数。

2、其中ApplicationObjectSupport类实现了ApplicationContextAware接口方法：

 

public final void setApplicationContext(ApplicationContext context) throws BeansException {
		if (context == null && !isContextRequired()) {
			// Reset internal context state.
			this.applicationContext = null;
			this.messageSourceAccessor = null;
		}
		else if (this.applicationContext == null) {
			// Initialize with passed-in context.
			if (!requiredContextClass().isInstance(context)) {
				throw new ApplicationContextException(
						"Invalid application context: needs to be of type [" + requiredContextClass().getName() + "]");
			}
			this.applicationContext = context;
			this.messageSourceAccessor = new MessageSourceAccessor(context);
			initApplicationContext();
		}
		else {
			// Ignore reinitialization if same context passed in.
			if (this.applicationContext != context) {
				throw new ApplicationContextException(
						"Cannot reinitialize with different application context: current one is [" +
						this.applicationContext + "], passed-in one is [" + context + "]");
			}
		}
	}

 以上红字加粗的代码非常重要。

 

3、在Jsr181HandlerMapping类中定义了该方法：

 

  protected void initApplicationContext()
            throws BeansException{
        if (serviceFactory == null) {
        	serviceFactory = createServiceFactory();
        }

        ApplicationContext context = getApplicationContext();
 
        while (true){
            if (context == null) break;
            
            processBeans(context, serviceFactory);

            context = context.getParent();
        }
    }

 

 

其中红色字体createServiceFactory();创建了AnnotationServiceFactory类的实例

      红色字体processBeans(context, serviceFactory);如下代码：

private void processBeans(ApplicationContext beanFactory, 
                          AnnotationServiceFactory serviceFactory){
        String[] beanNames = beanFactory.getBeanDefinitionNames();

        ConfigurableApplicationContext ctxt = (ConfigurableApplicationContext) beanFactory;

        // Take any bean name or alias that has a web service annotation
        for (int i = 0; i < beanNames.length; i++) {
            BeanDefinition def = ctxt.getBeanFactory().getBeanDefinition(beanNames[i]);
    
            if (!def.isSingleton() || def.isAbstract()) continue;
            
            Class clazz;
            Object bean;
            try
            {
                clazz = getApplicationContext().getType(beanNames[i]);
                bean = beanFactory.getBean(beanNames[i]);
                try
                {
                    clazz = SpringUtils.getUserTarget(bean).getClass();
                }
                catch (Exception e)
                {
                    logger.error("Failed to get the User Target Class of bean " + beanNames[i], e);
                }
            }
            catch (BeanIsAbstractException e)
            {
                // The bean is abstract, we won't be doing anything with it.
                continue;
            }

            if (clazz != null && 
                    !Modifier.isAbstract(clazz.getModifiers()) && 
                    webAnnotations.hasWebServiceAnnotation(clazz))
            {
               Service endpoint = serviceFactory.create(clazz);
                customizeService(bean, endpoint);
            }
            else
            {
                if (logger.isDebugEnabled())
                {
                    logger.debug("Rejected bean '" + beanNames[i] + "' since it has no WebService annotation");
                }
            }
        }
    }

 4、红色字体Service endpoint = serviceFactory.create(clazz); 是李永ServiceFactory创建Service的方法

   

 

      紫色字体customizeService(bean, endpoint);是定制系统使用的WebService,其中的代码为：

protected void customizeService(Object bean, Service endpoint) {
		if (logger.isInfoEnabled())
		{
		    logger.info("Exposing  service " + endpoint.getName() + 
		                " to " + urlPrefix + endpoint.getSimpleName());
		}
		if( getInHandlers()!= null ){//  添加  InHandlers
			endpoint.getInHandlers().addAll(getInHandlers());	
		}
		
		if( getOutHandlers()!= null ){//  添加  OutHandlers
			endpoint.getOutHandlers().addAll(getOutHandlers());	
		}
		
		if( getFaultHandlers()!= null ){//  添加  FaultHandlers
			endpoint.getFaultHandlers().addAll(getFaultHandlers());	
		}
		//----- 将该 WebService 调用XFire的注册器注入进去
		xFire.getServiceRegistry().register(endpoint);
		endpoint.setInvoker(new BeanInvoker(bean));
		Object controller = createController(endpoint.getName());
		registerHandler(urlPrefix + endpoint.getSimpleName(), controller);
	}
