Struts2从JSP访问枚举 [英] Struts2 accessing enum from JSP

问题描述

我有以下类

  package com.test; 
 
 public class SomeClass {
 public enum COLOR {RED，BLUE} 
} 
  

我想在我的JSP中访问 COLOR 枚举的值。我尝试了以下代码，但它不起作用。

 < s：property value =@ com.test .SomeClass.COLOR @ RED​​/> 
< s：property value =@ [e-mail]/> 
  

以前有哪些机构遇到这个问题？
[我已经在struts.xml中启用静态方法访问]

解决方案

对于枚举 -s不需要启用静态方法访问。

可以使用 @ 签名获取枚举：

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

在您的情况下，您声明枚举 c code code code code code code code code code $ c $ pre> < s：property value =@ com.test.SomeClass$COLOR@RED/>


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="@[e-mail]"/>

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

解决方案

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"/>
