分析原因：
struts2-core-2.1.2.jar中的struts-tags.tld中内容，
<tag>
<name>if</name>
<tag-class>org.apache.struts2.views.jsp.IfTag</tag-class>
<body-content>JSP</body-content>
<description><![CDATA[If tag]]></description>
<attribute>
<name>test</name>
<required>true</required>
<rtexprvalue>false</rtexprvalue>
<description><![CDATA[Expression to determine if body of tag is to be displayed]]></description>
</attribute>
<dynamic-attributes>false</dynamic-attributes>
</tag>
其中属性test的rtextpvalue为false，应当改为true支持EL表达式。

--------------------------
Thank you for you answer.the following is whole page content:
<%@ page contentType="text/html; charset=GBK" language="java"%>
<%@taglib prefix="s" uri="/struts-tags"%>
<html>
<head>
<title>s:if</title>
</head>
<body>
<s:set name="age" value="26" />
<s:if test="${age > 60}">
senior citizen
</s:if>
<s:elseif test="${age > 35}">
wrinkly
</s:elseif>
<s:elseif test="#attr.age > 25" id="wawa">
youth
</s:elseif>
<s:else>
laddie
</s:else>
</body>
</html>
"<%@taglib prefix="s" uri="/struts-tags"%>" show that i use struts2 tags.And exception throw at line of "<s:if test="${age > 60}">".Then I checked the struts-tags.tld in struts2-core-2.1.2.jar, and i found that <rtexprvalue>false</rtexprvalue> ,it's value is false(that is to say the test propertity in if tag doesn't support expression, I am not sure?).Later I modify the value of false to true ,then i jar struts2-core-2.1.2.jar again, i deployed the web application on tomcat6, there is no exceptions throws.
then i download struts-2.0.6,i found that <rtexprvalue>true</rtexprvalue> in struts2-tags.tld which in the struts2-core-2.0.5.jar.so i think this is a bug in the version 2.1.2.

[jira] Commented: (WW-2731) 运行s:if抛出异常，不支持EL表达式
Posted by "Dave Newton (JIRA)" <ji...@apache.org>.

Dave Newton commented on WW-2731:
---------------------------------
I'm telling you it's not a bug: JSTL expressions aren't accepted in attributes because of the potential security risk. This happened in 2.0.10.

Musachy Barroso resolved WW-2731.
---------------------------------
Resolution: Not A Problem
I don't understand Chinese , but based on the exception I see that you are using JSTL in your tags, please post your questions on the user mailing list. (better chance of getting an answer if it is in English)

Thank you for your answer.the following is whole page content:
<%@ page contentType="text/html; charset=GBK" language="java"%>
<%@taglib prefix="s" uri="/struts-tags"%>
<html>
<head>
<title>s:if</title>
</head>
<body>
<s:set name="age" value="26" />
<s:if test="${age > 60}">
senior citizen
</s:if>
<s:elseif test="${age > 35}">
wrinkly
</s:elseif>
<s:elseif test="#attr.age > 25" id="wawa">
youth
</s:elseif>
<s:else>
laddie
</s:else>
</body>
</html>
"<%@taglib prefix="s" uri="/struts-tags"%>" show that i use struts2 tags.And exception throw at line of "<s:if test="${age > 60}">".Then I checked the struts-tags.tld in struts2-core-2.1.2.jar, and i found that <rtexprvalue>false</rtexprvalue> ,it's value is false(that is to say the test property in if tag doesn't support expression, I am not sure?).Later I modify the value of false to true ,then i jar struts2-core-2.1.2.jar again, i deployed the web application on tomcat6, there is no exceptions throws.
then i download struts-2.0.6,i found that <rtexprvalue>true</rtexprvalue> in struts2-tags.tld which in the struts2-core-2.0.5.jar.I am not sure wether a bug or not.

then i download struts-2.0.6,i found that <rtexprvalue>true</rtexprvalue> in struts2-tags.tld which in the struts2-core-2.0.5.jar.so i think this is a bug in the version 2.1.2.
