Struts2 accessing enum from JSP

问题

I have the following class

package com.test;

public class SomeClass {
   public enum COLOR {RED,BLUE}
}

I want to access values of COLOR enum in my JSP. I've tried the following code but it doesn't work.

<s:property value="@com.test.SomeClass.COLOR@RED"/>
<s:property value="@com.test.SomeClass@COLOR.RED"/>

Any body came across this issue before? [I've already enabled static method access in struts.xml]

回答1:

For enum-s there is not need to enable static method access.

Enum-s can be accessed using @ sign like that:

<s:property value="@package.ENUM@enumvalue"/>

In your case since you are declaring enum inside class use $ sign to refer to your enum.

<s:property value="@com.test.SomeClass$COLOR@RED"/>
