Struts2 提交表单未导航到新视图

Question

我将 Struts2（版本 2.5.14.1）与 Spring 和 Tiles 插件一起使用。

这是我的（相关）struts.xml配置：

<package name="enrollment" namespace="/enrollment" extends="struts-bean-validation">
  <result-types>
    <result-type name="tiles" class="org.apache.struts2.views.tiles.TilesResult" />
  </result-types>

  <action name="start" class="io.shido.struts.action.enrollment.StartAction">
    <result name="success" type="tiles">enrollment.start.tiles</result>
  </action>
  <action name="personal-info" class="io.shido.struts.action.enrollment.PersonalInfoAction">
    <result name="input" type="tiles">enrollment.personal-info.tiles</result>
    <result name="success" type="tiles">enrollment.billing-info.tiles</result>
  </action>
  <action name="billing-info" class="io.shido.struts.action.enrollment.BillingInfoAction">
    <result name="input" type="tiles">enrollment.billing-info.tiles</result>
    <result name="success" type="tiles">enrollment.finish.tiles</result>
  </action>
  <action name="finish" class="io.shido.struts.action.enrollment.FinishAction">
    <result name="success" type="tiles">enrollment.finish.tiles</result>
  </action>
</package>

...包含以下形式之一的 JSP 文件：

<%@ taglib prefix="s" uri="/struts-tags" %>

<link rel="stylesheet" href="<s:url value='/resources/styles/enrollment.styles.css' />">

<s:form cssClass="form-input-info" action="personal-info" method="post">
  <legend><s:text name="legend.text" /></legend>
  <hr>
  <s:textfield cssClass="form-control" key="textfield.first-name" name="personalInfo.firstName" />
  <s:textfield cssClass="form-control" key="textfield.last-name" name="personalInfo.lastName" />
  <s:textfield cssClass="form-control" key="textfield.email" name="personalInfo.email" />
  <s:textfield cssClass="form-control" key="textfield.phone-number" name="personalInfo.phoneNumber" />
  <s:textfield cssClass="form-control" key="textfield.age" name="personalInfo.age" />
  <s:submit class="btn btn-primary btn-lg btn-block" key="submit.continue" />
</s:form>

...最后（超级简单）Action class:

package io.shido.struts.action.enrollment;

// imports

public final class PersonalInfoAction extends ActionSupport {
  private static final long serialVersionUID = 3560814234131884357L;

  private final Logger logger = LogManager.getLogger(this.getClass());

  private PersonalInfoHandler handler;

  @Valid
  private PersonalInfo personalInfo;

  @Override
  public String execute() {
    // If personalInfo is not null is guaranteed to be valid due to Bean Validation contraints
    if (null != personalInfo) {
      logger.debug("Processing personal info...");
      handler.save(personalInfo);
      return Action.SUCCESS;
    }
    logger.info("Collecting personal info...");
    return Action.INPUT;
  }

  public PersonalInfoHandler getHandler() { return handler; }

  public void setHandler(final PersonalInfoHandler handler) { this.handler = handler; }

  public PersonalInfo getPersonalInfo() { return personalInfo; }

  public void setPersonalInfo(final PersonalInfo personalInfo) {
    this.personalInfo = personalInfo;
    this.personalInfo.normalize();
  }
}

问题是，每当我提交该表单时，我都希望 Bean 验证能够启动并检查所有带注释的字段（检查，这正在发生），当一切正常时，将流程发送到 /WEB-INF/content/enrollment/billing-info.jsp（在 enrollment.billing-info.tiles 的 Tiles 中定义）...但我所看到的（几乎）是带有错误标签的 "billing info" 表单。见下图：

URL 以及标签应该已经更改。要将樱桃放在最上面，如果我再次单击 Continue 按钮，表格就会正确显示。

有什么线索吗？

Answer 1

我没有直接的答案，但您可以尝试使用重定向操作而不是多次使用磁贴。

所以你可以在这里试试这个：

 <action name="personal-info" class="io.shido.struts.action.enrollment.PersonalInfoAction">
    <result name="input" type="tiles">enrollment.personal-info.tiles</result>
    <result name="success" type="redirectAction">
        <param name="actionName">billing-info</param>
    </result>
 </action>

如果您需要传输某种 id 来显示数据，您可以在 struts.xml 中使用额外的参数，如下所示：

<!-- rest as above -->
<result>
<param name="param1">${value1}</param>
</result>

param1 必须在两个操作中都具有有效的 getter/setter-methods 才能传输信息。
