在jsp和java之间重用变量名（Spring） [英] Reusing variable names between jsp and java (Spring)
问题描述
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
<$ p $ （allDomainOrGroupParentDetails，
getDomainOrGroupParentResponse.getDomainOrGroupParentPojoWrappers（））;
From ，我试着做下面的事情：
public class ModelObjectKeys {
public static class OnLoadAddDriverConstants {
$ b}
public static final String allDomainOrGroupParentDetails =allDomainOrGroupParentDetails;
}
而在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>
我也像这样在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 // ENhttp://www.w3.org/TR/html4/loose.dtd\">
< html>
< head>
仍然不起作用。我得到
org.apache.jasper.JasperException：
/WEB-INF/views/onLoadAddDriverView.jsp（行：270 ，列：10）
$ {<％= ModelObjectKeys.allDomainOrGroupParentDetails％>}包含
无效表达式
我缺少什么？

更改 不能在EL表达式中嵌套脚本 My existing jsp is My existing Spring Java is From this, I tried to do the following And in the jsp I did I also imported the java file in the html like this Still it does not work. I get org.apache.jasper.JasperException:

"${<%=ModelObjectKeys.allDomainOrGroupParentDetails%>}" contains
invalid expression(s) What am I missing ? EDIT
Change You can't nest scripting inside EL expression 这篇关于在jsp和java之间重用变量名（Spring）的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持IT屋！ items =$ {<％= ModelObjectKeys.allDomainOrGroupParentDetails％>}
to items =$ {ModelObjectKeys.allDomainOrGroupParentDetails}
<c:forEach var="domainOrGroupParentDetails"
items="${allDomainOrGroupParentDetails}" varStatus="status">
<option
value="${domainOrGroupParentDetails.domainOrGroupParentPojo.name}">
${domainOrGroupParentDetails.domainOrGroupParentPojo.name}</option>
</c:forEach>
data.put("allDomainOrGroupParentDetails",
getDomainOrGroupParentResponse.getDomainOrGroupParentPojoWrappers());
public class ModelObjectKeys {
public static class OnLoadAddDriverConstants {
}
public static final String allDomainOrGroupParentDetails = "allDomainOrGroupParentDetails";
}
