xmen:service interfacexxx.xxx.xxx.service refxxx port8000/定义服务引用标签xmen:referer idxxxService interfacexxx.xxx.xxx.service/UML图设计如下 RegistyConfig、ServiceConfig、RefererConfig分别继承自抽象类AbstractConfig并分别定义了三个标签的相关属性。ServiceConfigBean、RefererConfigBean用于实现spring的相关接口达到对配置文件中bean进行处理的目的。 二、定义xsd文件xmen.xsd ?xml version1.0 encodingUTF-8?
