摘　　要：目前的Portlets协作方法忽略了Portlets多步骤交互的特性,并局限于简单的数据类型。给出了一种新的Portlets协作方法。利用Wrapper技术将Portlet抽象为WrapperPlayer组件。描述了WrapperPlayer组件与具体的Portlet页面的映射关系;使用数据流动路径(DFPath)在HTML片段中定位Socket与Blot;提出了使用数据类型匹配的方式进行Portlet之间的数据协作,并给出了精确匹配与等价类匹配两种不同的匹配方式以实现类型转换,从而使Portlets协作支持多步骤交互与复杂的数据类型。Multi-step interaction and complex data types are not supported by current Portlets cooperation approaches. A novel multistep interaction-oriented approach for Portlets cooperation is proposed. A component called WrapperPlayer is abstracted from specific Portlet and the mapping between WrapperPlayer and specific Portlet pages is described. Furthermore, data flow path （DFPath） syntax is defined to identify sockets and blots in WrapperPlayer. Finally, a Portlet cooperation approach using data type matching is presented, in which the organization and management model for data types are given. In addition, two data type matching methods, i.e. precise matching and equivalence matching, are introduced to implement type conversion.
