网络框架 Retrofit(二)-白红宇

Xml格式配置你好,我是kpioneer 你好,我是Jeason 你好,我是Cook

注意：@Root：注解代表Xml根节点（需要在类上面使用）例如：

@Element：注解代表根节点中下面子节点       例如：
                 @Attribute：注解代表标签页中的属性       例如：userid = '1'                @Text：注解代表标签内容       例如：你好,我是kpioneer复制代码

解析器源码:

.addConverterFactory(xxxxFactory.create()) 采用抽象工厂模式抽象工厂模式是工厂方法模式的进一步延伸，由于它提供了功能更为强大的工厂类并且具备较好的可扩展性

简单区分：抽象工厂模式：一组相关性很高的方法工厂方法模式：一个方法
