命令按钮链接到Spring Web Flow Project中的错误路径名

标签： spring richfaces spring-webflow commandbutton

我试图将两个数字加在一起并显示输出，但我有渲染问题。

我从ajax日志中得到了这个。 （为了便于阅读而空格不清）

info [12:44:10.893]: Element error 
<error>
  <error-name>
    class com.sun.faces.context.FacesFileNotFoundException
  </error-name>
  <error-message>
    <![CDATA[/WEB-INF/WEB-INF/intro.xhtml Not Found in ExternalContext as a Resource]]>
  </error-message>
</error>

我看不到它在路径名中获取两个WEB-INF文件夹的位置。

这个问题的第二部分是我不确定应该在哪里调用calculator.sum。这可能会影响结果或需要在单独的问题中。 ＃{calculator.sum}是单击按钮时调用的输出。

这是我正在编辑的表单。      

 <rich:panel id="UserManagePanel" header="Welcome to test">

 <a href="main">Enter The WebFlow</a>
  <br/>
  <br/>
  <br/>
    <h:inputText id="additive1" value="#{calculator.a}"/>
  <br/>
    <h:inputText id="additive2" value="#{calculator.b}"/>
  <br/>
    <a4j:commandButton type="button" id="btn_add" action="#{calculator.sum}" value="Add" reRender="out" execute="@form"/>
  <br/>

  <a4j:outputPanel id="out">
    <h:outputText value="#{calculator.sum}" rendered="true"/>
  </a4j:outputPanel>
  <br/>

  <a4j:log/>

   </rich:panel>
  </h:form>

Java类Calculator.java 

package demo;

import javax.faces.bean.*;

import org.springframework.stereotype.Component;

@ManagedBean
@Component
@ViewScoped
public class Calculator implements java.io.Serializable{

      private static final long serialVersionUID = -3832235132261771583L;

      private int _a;
      private int _b;

      public int getA() { return _a; }
      public void setA(int a) { _a = a; }

      public int getB() { return _b; }
      public void setB(int b) { _b = b; }

      public int getSum()
      {
        return _a + _b;
      }

}

我正在使用的库： 使用Richfaces 4.3.4 Spring Security 3.1.3 JSTL 1.2.1 Spring 3.2.0.RELEASE

2 个答案:

答案 0 :(得分：0)

由于calculator.sum仅返回数字（并且在后台不执行任何操作），因此单击按钮时无需调用它。

我不知道导致错误的原因，但WEB-INF是配置文件和类似的东西。如果您有任何（x）html页面，请将它们移出。

答案 1 :(得分：0)

要实现这一目标，必须要做一些事情。

1）来自flowlistener下的webmvc-config.xml的WEB-INF /。
2）并且必须习惯至少调试它 3）表格必须在标签中。
4）网址必须使用网络流 

http://localhost:8080/CLPWeb/spring/grantSearchFlow?test

  rather than

http://localhost:8080/CLPWeb/spring/WEB-INF/templates/views/test.xhtml

使用url作为代码来验证它。
