Struts2 开发者模式不可用，求解

wglpd 2013-12-19 10:24:19

使用的是struts-2.3.16版本，tomcat-6.0版本，jdk-7.0,myeclipse-10

<constant name="struts.devMode" value="true" />设置好，发布，可运行。

修改<action name="aaa">中aaa后，更改地址刷新报错，换回原来的地址依旧可行。

错误提示：
You are seeing this page because development mode is enabled. Development mode, or devMode, enables extra debugging behaviors and reports to assist developers. To disable this mode, set:

struts.devMode=false
in your WEB-INF/classes/struts.properties file.

将 <constant name="struts.configuration.xml.reload" value="true"/>替换掉<constant name="struts.devMode" value="true" />,然后重新运行服务器，tomcat自动加载，访问时不会报错。（备注：我的tomcat路径不存在空格）
