public enum PlatformConstants {        KING("8"),               CAT("9"),                                         private String value;                  PlatformConstants(String value) {              this.value = value;          }                    public String getName() {              return value;          }      }

<%@page import="com.vip.mlisting.constants.PlatformConstants"%><%@include file="../main/header.jsp"%><%String path = request.getContextPath();%><!-- app 常量 --><c:set var="KING" value="<%=SalePlatformConstants.KING.getName()%>"/><c:set var="CAT" value="<%=SalePlatformConstants.CAT.getName()%>"/>
