如何获取搜索结果并使用struts 2应用程序中的数据表进行渲染
我有一个struts 2应用程序，我想在其中使用数据表来获取搜索结果并显示它们。屏幕如下图所示。
我希望它最终看起来像这样，我想使用数据表来获取ajax调用的结果。
我有一个动作类（Dashboard.java），其方法名为viewSearchResult（），如下所示。
import java.util.List;
import com.opensymphony.xwork2.ActionSupport;
import com.schenker.ocean.dao.SearchUpdateDAO;
import com.schenker.ocean.vo.Shipment;
public class Dashboard extends ActionSupport{
/**
*
*/
private static final long serialVersionUID = 1L;
//members
private String stt;
private String hawb;
private String chi;
private String invoice;
private String shipment;
private String Search;
private String tabIndex;
private String searchType;
private List<Shipment> aaData;
public String getTabIndex() {
return tabIndex;
}
public void setTabIndex(String tabIndex) {
this.tabIndex = tabIndex;
}
public String getSearch() {
return Search;
}
public void setSearch(String search) {
Search = search;
}
//getters and setters for members
public String getStt() {
return stt;
}
public void setStt(String stt) {
this.stt = stt;
}
public String getHawb() {
return hawb;
}
public void setHawb(String hawb) {
this.hawb = hawb;
}
public String getChi() {
return chi;
}
public void setChi(String chi) {
this.chi = chi;
}
public String getInvoice() {
return invoice;
}
public void setInvoice(String invoice) {
this.invoice = invoice;
}
public String getShipment() {
return shipment;
}
public void setShipment(String shipment) {
this.shipment = shipment;
}
//methods
public String getDashboard(){
return "success";
}
public String viewSearchResult(){
SearchUpdateDAO sudao= new SearchUpdateDAO();
aaData=sudao.getViewSearch(chi, stt, hawb, invoice, shipment, "");
return "success";
}
public String assignSearchResult(){
return "success";
}
public String shipDocsResult(){
return "success";
}
public String assignUpdateResult(){
return "success";
}
public String getSearchType() {
return searchType;
}
public void setSearchType(String searchType) {
this.searchType = searchType;
}
public List<Shipment> getAaData() {
return aaData;
}
public void setAaData(List<Shipment> aaData) {
this.aaData = aaData;
}
}
我的jsp页面（左侧也有搜索菜单）位于下方。

我的问题是如何获取数据表来调用viewSearchResult（）并传递searchform中的参数？我如何确保响应由数据表处理，而不是由struts转发到另一个页面？

答案 0 :(得分：0)
您可以使用struts-json插件以json格式从动作类中获取响应。稍后渲染使用任何一种javascript方法（jQuery，jTable，dojo等）
要从动作类作为json对象返回，您必须在struts动作定义中将返回类型设置为json，如下所示。
<action name="writeJSON" class="com.rajesh.json.ReadJSON" method="writeJSON">
<result type="json" />
要通过ajax向服务器发送和接收数据并通过json获取响应，请参阅以下链接。
