Spring Web Flow 1.0 EA 发布

Spring Web Flow 1.0 EA 发布了Spring WebFlow是一个及其优秀的Web开发框架,用于在Web应用内部创建和配置可重用的Web流程.Spring WebFlow 使得Web架构师们可以将精力集中在Web应用开发的抽象层次上:Web流程的逻辑结构和Web事件条件的定义。官方提到的特性包括:Support for binding directly to backing business services from a flow definition (eliminating the need for trivial Action adapter glue code)Support for four (4) distinct flow response types out-of-the box (view forward, conversation redirect, flow redirect, external redirect)Multiple strategies for launching flows and accessing/refreshing/bookmarking ongoing conversations (parameter-based, path-based [REST-style])Simplified support for deploying flow definitions for executionSpring Portlet MVC integration, for executing flows in a JSR 168 Portlet environmentJSF integration, for executing flows in a JSF environmentImproved support for persisting flow executions across requests and tracking (and securing access to) ongoing conversations within a repository.Automatic externalized flow definition change detection and 'hot reloading'Support for global transitions shared by all states of a flowSupport for importing one or more Spring bean definition files into a flow definition, providing a context for configuring custom flow artifacts such as actions, attribute mappers, exception handlers, view selectors, and transition criteriaSupport for 'inline-flows,' flow definitions fully local and contained within an outer flow definitionSupport for exception handling at both the flow and state levelMiscellaneous improvements in many areas including but not limited to Java-based flow building, flow execution testing, flow execution listening, conversation locking, flow execution serialization, attribute and parameter map access support, flow attribute mapping, and piecemeal page-level form validation
