如何在JSF中禁用jftfdi jffi查询参数 [英] How to disable jftfdi jffi query params in JSF

问题描述

我尝试了JavaServer Faces 2.2(Mojarra 2.2.4)的最新版本 并注意到以这种不需要的方式更改了我的查询字符串:

I tried the last version of JavaServer Faces 2.2 (Mojarra 2.2.4) and noticed changing my query string in this unwanted way:

page.jsf?jftfdi=&jffi=

代替

page.jsf

我发现这是新的JSF 2.2功能.但是这些查询参数(jftfdi，jffi)破坏了我对SEO友好的网址.如何禁用它?

I've found that it is the new JSF 2.2 feature. But these query params(jftfdi, jffi) spoil me SEO-friendly urls. How can I disable it?

推荐答案

这是Mojarra中的错误.如果无法进行任何流导航配置(通过新的@FlowScoped注释和<j:flow-xxx>标签).

This is a bug in Mojarra. They should not have been appended when there's no means of any flow navigation configuration (by the new @FlowScoped annotation and <j:flow-xxx> tags).

基本上，负责<h:link>和<h:button>的HTML输出生成的OutcomeTargetRenderer类错误地检查了 javadoc 基本实现永远不会返回null，而是一个空字符串.因此，渲染器始终认为它在流导航的中间，并且始终附加关联的jftfdi和jffi请求参数.解决方法是让它也检查是否返回非空字符串.

Basically, the OutcomeTargetRenderer class who's responsible for HTML output generation of the <h:link> and <h:button> is incorrectly checking if NavigationCase#getToFlowDocumentId() returns non-null before appending the flow navigation parameters. However, based on the javadoc the base implementation never returns null, but an empty string. Therefore, the renderer always thinks that it's in middle of a flow navigation and always appends the associated jftfdi and jffi request parameters. The fix is to let it check as well if it returns a non-empty string.

我将其报告为 issue 3054 ，他们确认这是一个错误，并且目前正在研究中.该修补程序可能会在Mojarra 2.2.5中提供.

I reported it as issue 3054 and they confirmed that this is a bug and are currently working on it. The fix will likely be available in Mojarra 2.2.5.

更新:截至目前，不到一天，它已针对2.2.5进行了固定.

Update: as of now, less than a day later, it's fixed for 2.2.5.

顺便说一句， jftfdi 代表"javax.faces到流文档ID"，它在

By the way, the jftfdi stands for "javax.faces To Flow Document ID" which is specified as follows in the javadoc:

由组件家族javax.faces.OutcomeTarget的渲染器渲染的组件必须使用此常量作为参数名称的参数名称，该参数表示该组件将导致输入的流的定义文档ID.

Components that are rendered by Renderers of component-family javax.faces.OutcomeTarget must use this constant as the parameter name for a parameter representing the defining document id of the flow that this component will cause to be entered.

和 jffi 代表在javax.faces流ID" ="noreferrer"> javadoc :

and the jffi stands for "javax.faces Flow ID" which is specified as follows in the javadoc:

由组件家族javax.faces.OutcomeTarget的渲染器渲染的组件必须使用此常量作为参数名称，该参数代表表示将导致输入该组件的流的流ID的参数.

Components that are rendered by Renderers of component-family javax.faces.OutcomeTarget must use this constant as the parameter name for a parameter representing the flow id of the flow that this component will cause to be entered.
