我现有的jsp是
<c:forEach var="domainOrGroupParentDetails"
items="${allDomainOrGroupParentDetails}" varStatus="status">
<option
value="${domainOrGroupParentDetails.domainOrGroupParentPojo.name}">
${domainOrGroupParentDetails.domainOrGroupParentPojo.name}</option>
</c:forEach>
我现有的 Spring Java 是
data.put("allDomainOrGroupParentDetails",
getDomainOrGroupParentResponse.getDomainOrGroupParentPojoWrappers());
来自this ，我尝试执行以下操作
public class ModelObjectKeys {
public static class OnLoadAddDriverConstants {
}
public static final String allDomainOrGroupParentDetails = "allDomainOrGroupParentDetails";
}
在jsp中我做了
<c:forEach var="domainOrGroupParentDetails"
items="${<%=ModelObjectKeys.allDomainOrGroupParentDetails%>}" varStatus="status">
<option
value="${domainOrGroupParentDetails.domainOrGroupParentPojo.name}">
${domainOrGroupParentDetails.domainOrGroupParentPojo.name}</option>
</c:forEach>
我还像这样在html中导入了java文件
<%@ page import="com.mnox.corporate.model.design.ModelObjectKeys"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
还是不行。我明白了
org.apache.jasper.JasperException: /WEB-INF/views/onLoadAddDriverView.jsp (line: 270, column: 10) "${<%=ModelObjectKeys.allDomainOrGroupParentDetails%>}" contains invalid expression(s)
我错过了什么？

最佳答案
更改items="${<%=ModelObjectKeys.allDomainOrGroupParentDetails%>}"
至items="${ModelObjectKeys.allDomainOrGroupParentDetails}"
不能在 EL 表达式中嵌套脚本
