public String getParamUrl() {
String url = "";

if (url.indexOf("?") == -1) {
url = url + "?";
}
String totalParams = "";
Enumeration params = this.request.getParameterNames();// 得到所有参数名
while (params.hasMoreElements()) {
String tempName = params.nextElement().toString();
String tempValue = https://www.04ip.com/post/this.request.getParameter(tempName);
if (tempValue != null!tempValue.equals("")
!tempName.equals("currentpage")) {
if (totalParams.equals("")) {
totalParams = totalParams + tempName + "=" + tempValue;
} else {
totalParams = totalParams + "" + tempName + "="
+ tempValue;
}
}
}
String totalUrl = url + totalParams;
return totalUrl;
}
}
求java分页代码，急用！package common.util;
import java.util.*;
public class PageController implements IPageModel {
