用于分页的Struts2中的DisplayTag
我想对我的struts2 web应用程序应用分页。当用户登录时，我会将他们重定向到主页，我希望在主页上使用用于分页的Struts2中的DisplayTag,struts2,displaytag,Struts2,Displaytag,我想对我的struts2 web应用程序应用分页。当用户登录时，我会将他们重定向到主页，我希望在主页上使用display标记显示分页中的所有用户 我已经做了研究，并最终将其集成到我的struts2中，但是当我在登录后运行代码时，它会显示消息找不到要显示的内容 当我在struts1.3中做了同样的事情，从中获取示例时，它是有效的。 我已将以下JAR文件复制到我的lib文件夹中： commons-logging.jar commons-lang.jar commons-collections.jar

我不确定，但我猜是
requestURIdisplaytagname=“sessionScope.UserForm.userList”<input id="username" name="username" value="%{data.firstName}" disabled="disabled"/>
它直接使用用户属性的getter。顺便说一下，我不确定你的残疾标签。您可能应该改为使用readonly。您已经为显示标记设置了记录总数，如
<display:table id="data" name="lstEntities"
sort="external" uid="row" htmlId="rowid" class="tborder"
style="width:100%" excludedParams="*"
pagesize="${pageCriteria.recordsPerPage}" partialList="true"
size="${pageCriteria.totalRecords}" export="false"
requestURI="XXX.action">
public class PaginationCriteria implements Cloneable, CommonConstants,
Serializable {
/**
* Holds the Unie value of Class.
*/
private static final long serialVersionUID = 8047568459658871831L;
/**
* Stores cache Mode.
*/
private boolean cached;
/**
* Stores current page number in the user screen.
*/
private int currentPage;
/**
* Holds the Name of the attribute in Entity to be unique.
*/
private String distinctRootEntityName;
/**
* Stores the information about no of entities to be fetched.
*/
private boolean fetchAll;
/**
* Stores the information about no. of records to be fetched.
*/
private int recordsPerPage;
/**
* Stores the secondary sort column of the entity.
*/
private String secondarySortBy;
/**
* Stores the Sort column of the entity.
*/
private String sortBy;
/**
* Stores the sort order of the entity.
*/
private boolean sortDescending;
/**

*/
private int totalRecords;
//Getters and setters of this properties
}
希望能有帮助。如果您需要任何其他信息，请告诉我。我对jsp开头的taglib指令感兴趣。我对struts1的引用和标记这个struts2感到非常困惑。我用taglib指令更新我的问题check it@QuaternionI不使用display标记，所以我只是猜测一下。我猜显示标签使用常规EL，而Struts2使用OGNL。所以显示表中的“name”属性并没有将“list”推到堆栈的顶部，所以s2标记不知道它们正在处理什么。。。尝试以下两件事：在s2属性中，而不是在“firstName”中写入“list.firstName”（如果出现了什么，那么我们知道我说的是真的），然后尝试将所有属性标记替换为“${fieldName}”（没有角度标记！只使用该表达式[其中fieldName当然是字段名]，然后查看是否发生了什么）
