Question

我只是使用Primefaces测试JSF 2并且正在设置一个基本的测试表单。目标是提交表单，然后将用户发送到列出所有条目的页面。

但如果我点击“添加”按钮发生的一切就是我的webapp尝试导航到页面：“//pages/index.xhtml”，并且没有找到任何内容......

任何想法？我已经按照教程了，但无法看到我错在哪里.. 我已将命令按钮映射到ManagedBean方法“addUser”。 addUser方法返回“success”，我已设置“success”转到success.xhtml ..

我现在花了3个小时调试这个，我即将发疯，所以任何帮助都会非常适合......

的index.xhtml：

<html xmlns="http://www.w3.org/1999/xhtml" xmlns:h="http://java.sun.com/jsf/html" xmlns:f="http://java.sun.com/jsf/core" xmlns:p="http://primefaces.org/ui">
    <h:head><title>Welcome to OTV_JSF_Spring_Hibernate_Project</title></h:head>
    <h:body>
        <h:form>
          <table>
              <tr>...</tr>
              <tr>
                 <td><p:commandButton id="addUser" value="Add" action="#{userMB.addUser}" ajax="false"/></td>
                 <td><p:commandButton id="reset" value="Reset" action="#{userMB.reset}" ajax="false"/></td>
              </tr>
          </table>
      </h:form>
    </h:body>
</html>

userMB：

@ManagedBean(name = "userMB")
@RequestScoped
public class UserManagedBean implements Serializable {
    private static final String SUCCESS = "success";
    private static final String ERROR = "error";
    /* .... */

    public String addUser() {
        return SUCCESS;
    }

我认为你必须这样写：

<?xml version="1.0" encoding="UTF-8"?>
<faces-config
        xmlns="http://java.sun.com/xml/ns/javaee"
        xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
        xsi:schemaLocation="http://java.sun.com/xml/ns/javaee
            http://java.sun.com/xml/ns/javaee/web-facesconfig_2_0.xsd"
        version="2.0">

    <!-- JSF and Spring are integrated -->
    <application>
        <el-resolver>
            org.springframework.web.jsf.el.SpringBeanFacesELResolver
        </el-resolver>
    </application>

    <!-- configuration of navigation rules -->
    <navigation-rule>
        <from-view-id>pages/index.xhtml</from-view-id>
        <navigation-case>
            <from-outcome>success</from-outcome>
            <to-view-id>pages/success.xhtml</to-view-id>
        </navigation-case>
        <navigation-case>
            <from-outcome>error</from-outcome>
            <to-view-id>pages/error.xhtml</to-view-id>
        </navigation-case>
    </navigation-rule>

</faces-config>
