motan解读：添加spring 支持
代码位置：
motan-core的目录下
motan中使用spring管理配置对象。motan利用Spring的spi机制创建了自定义标签和相应的标签处理代码。具体使用方法见这篇。本文以motan为例，探讨如何扩展spring的schema.
1.首先，如果要自定义标签，不得不加上响应的xsd文件，这个文件可以对xml的格式进行约束。可以看到以下的自定义标签应该遵循的格式。对于新增的xsd文件，还要建立一个spring.schemas文件，加上这个xsd文件。

2.有个标签的格式，还需要标签的处理器，标签的处理器只要简单的继承NamespaceHandlerSupport这个类，具体的类如下，其中在init方法中，定义了标签和对应的解析器。motan中的对XML的解析起都是MotanBeanDefinitionParser，最终一对标签，最终转化为相应的BeanDefination.并放在一个并发的hashMap中，key为id,value是相应的beanDefination.
public class MotanNamespaceHandler extends NamespaceHandlerSupport {
public final static Set<String> protocolDefineNames = new ConcurrentHashSet<String>();
public final static Set<String> registryDefineNames = new ConcurrentHashSet<String>();
public final static Set<String> basicServiceConfigDefineNames = new ConcurrentHashSet<String>();
public final static Set<String> basicRefererConfigDefineNames = new ConcurrentHashSet<String>();
@Override
public void init() {
registerBeanDefinitionParser("referer", new MotanBeanDefinitionParser(RefererConfigBean.class, false));
registerBeanDefinitionParser("service", new MotanBeanDefinitionParser(ServiceConfigBean.class, true));
registerBeanDefinitionParser("protocol", new MotanBeanDefinitionParser(ProtocolConfig.class, true));
registerBeanDefinitionParser("registry", new MotanBeanDefinitionParser(RegistryConfig.class, true));
registerBeanDefinitionParser("basicService", new MotanBeanDefinitionParser(BasicServiceInterfaceConfig.class, true));
registerBeanDefinitionParser("basicReferer", new MotanBeanDefinitionParser(BasicRefererInterfaceConfig.class, true));
registerBeanDefinitionParser("spi", new MotanBeanDefinitionParser(SpiConfigBean.class, true));
}
}
