如何将参数传递给Spring Webflow [英] How to pass parameters to spring webflow

问题描述

我正在处理Spring Webflow.我的应用程序中有两个Webflow，一个用于添加人员详细信息，另一个用于修改人员详细信息.两种流程都工作正常.现在，我想将参数传递给我的修改流程并访问它，以便我可以根据传递的参数预先选择一些值.在以下提到的情况下如何实现?

I am working on spring webflows. I have two webflows in my application, one to add a person details and one to modify the person details. Both flows are working fine. Now I would like to pass parameter(s) to my modify flow and access it, so that I can preselect some of the values based on the passed parameter. How can I achieve it for below mentioned scenarios?

1. 从添加流结束"状态开始.
2. 从流程外部，即从应用程序中除添加流程以外的任何地方.

推荐答案

我知道了.最后，它非常简单，我只需要在url中传递参数并使用flow.xml中的输入标签获取传递的参数.早些时候我没有使用输入标签.

I figured it out. In the end it was very simple and i just had to pass the parameters in url and get the parameters that I pass using input tag in the flow.xml. Earlier i wasn't using the input tag.

网址将类似于此

http://localhost:8080/modifyPerson?personName=xxx

然后在flow.xml中使用输入标签检索所传递的personName参数，并将其设置为模型.

Then in flow.xml personName parameter that is passed is retrieved using input tag and set to the model.

 <input name="personName"/>

 <view-state id="modifyBasics" view="modifyBasics" model = "person">
    <on-render>
        <set name="person.personName" value="personName"></set>
    </on-render>
    ....
 </view-state>
