验证失败后加载相同的 url

Question

验证工作正常。在添加操作时，加载新表单供用户填写。提交后，验证在 processAdd() 上完成。一切都很好。

问题：

用户在http://localhost:8000/Struts2_Spring_Crud/student/add 填写表格。提交后通过http://localhost:8000/Struts2_Spring_Crud/student/processAdd 处理和验证。如果验证失败，我的 url 是 /processAdd。当验证失败时，我想在 /add 。有没有办法做到这一点？

<s:form action="processAdd" method="POST">
    <s:submit method="execute" value="#title"/>
 </s:form>

  public String execute() throws Exception {
        System.out.println("execute() executed");
        //Process form data
        return SUCCESS;
    }

    public String input() throws Exception {
        System.out.println("input() executed");
        //Prepare form data
        return INPUT;
    }

     <default-action-ref name="list"/>
        <action name="list" class="com.myapp.actions.StudentAction" method="getAllStudents">
            <result name="success" type="tiles">/student.list.tiles</result>
        </action>

        <action name="add" class="com.myapp.actions.StudentAction" method="input">
            <result name="input" type="tiles">/student.edit.tiles</result>
            <result name="failure" type="tiles">/student.edit.tiles</result>
        </action>

        <action name="processAdd" class="com.myapp.actions.StudentAction">
            <result name="success" type="redirectAction">list</result>
            <result name="input" type="tiles">/student.edit.tiles</result>
            <result name="failure" type="redirectAction">add</result>
        </action>

Answer 1

试试这个：

<action name="processAdd" class="com.myapp.actions.StudentAction">
  <result name="success" type="redirectAction">list</result>
  <result name="input" type="redirectAction">add</result>
  <result name="failure" type="redirectAction">add</result>
</action>
