Using a variable using a variable value in EL

I want to access a variable of type Map from my model using EL. e.g.

${name} = "mycar"
${mycar} = "ferrari"

I tried ${${name}} but it doesn't work. The expected value is "ferrari". What do you think is the co开发者_运维知识库rrect syntax for this?

I don't think you can do that. However, you can have a Map in your Java code that will be accessible using ${myMap[myValue]}. So for example, in your JSP page you will have:

<c:set var="name" value="mycar"/>
<c:set var="myCar" value="${carsMap[name]}"/>

it's like you called carsMap.get("mycar"); in Java...

You can then loop around your map.

<c:forEach var="entry" items="${map}">
   ${entry.key}: ${entry.value}, 
</c:forEach>
