问题 I am developing an application using Struts 2 and Hibernate. On a JSP page I have one form in which all CRUD operations I am performing. I want my Form data to be persisted, which is temporarily entered in the form fields. One approach which I tried is to bind all the data into an Object and store that object in a session or cache but I know there is some limitation of storing data like this. My form is having the functionality to add n number of rows which means I have to store large amount

问题 According this solution Struts2 handle multiple actions... I know the Struts2 DMI can handle multiple acitons in single form easily. Recently, Struts2 turned off DMI mechanism for security issue. Now, we use WILDCARD MAPPINGS to map all actions in struts.xml example: <action name="*/*" class="action.{1}Action" method="{2}"> ... </action> In WILDARD MAPPINGS, it has a little problem to deal with mapping multiple actions/methods in single form. <s:form action="actionA/method2" theme="simple" >

问题 I'm having some trouble accessing a specific element of a list when the index is a variable. When the index is just a number, I have no issues at all displaying what I'm looking for. <s:property value="#session.userList[1].email" /> That works perfectly, and displays the email found in that element of UserList However, when I change the index to be a variable, I'm having difficulties finding the proper way to write the ognl statement.
