【一】：配置项
<dubbo:monitor protocol="registry"/>
【二】：配置解析器
-->具体解析器为com.alibaba.dubbo.config.spring.schema.DubboNamespaceHandler配置的com.alibaba.dubbo.config.spring.schema.DubboBeanDefinitionParser、
【三】：配置目标
-->这个配置会向IOC容器中注册一个bean,该class为com.alibaba.dubbo.config.MonitorConfig
-->这个bean描述的是监控的相关配置信息
-->描述属性：id,protocol（传输协议），address（地址），username（用户名），password( 密码)，group(分组)，version（版本号），parameters(自定义参数)，isDefault(是否缺省）
【四】类
