大家看一下 这些提示是什么意思？

问题描述

我把log4j.properties删除了也会出现这些。这些警告好烦的，之前都没有的。11:20:12,625 WARN com.opensymphony.xwork2.ognl.OgnlValueStack:46 - Could not find property [struts.valueStack]11:20:12,765 WARN com.opensymphony.xwork2.ognl.OgnlValueStack:46 - Could not find property [org.apache.catalina.jsp_file]11:20:12,968 WARN com.opensymphony.xwork2.ognl.OgnlValueStack:46 - Could not find property [templateDir]11:20:12,968 WARN com.opensymphony.xwork2.ognl.OgnlValueStack:46 - Could not find property [templateDir]11:20:12,968 WARN com.opensymphony.xwork2.ognl.OgnlValueStack:46 - Could not find property [theme]11:20:12,984 WARN com.opensymphony.xwork2.ognl.OgnlValueStack:46 - Could not find property [theme]11:20:12,984 WARN com.opensymphony.xwork2.ognl.OgnlValueStack:46 - Could not find property [templateDir]11:20:12,984 WARN com.opensymphony.xwork2.ognl.OgnlValueStack:46 - Could not find property [templateDir]11:20:12,984 WARN com.opensymphony.xwork2.ognl.OgnlValueStack:46 - Could not find property [theme]11:20:12,984 WARN com.opensymphony.xwork2.ognl.OgnlValueStack:46 - Could not find property [theme]11:20:13,468 WARN com.opensymphony.xwork2.ognl.OgnlValueStack:46 - Could not find property [.freemarker.Request]11:20:13,468 WARN com.opensymphony.xwork2.ognl.OgnlValueStack:46 - Could not find property [.freemarker.RequestParameters]11:20:13,562 WARN com.opensymphony.xwork2.ognl.OgnlValueStack:46 - Could not find property [templateDir]11:20:13,562 WARN com.opensymphony.xwork2.ognl.OgnlValueStack:46 - Could not find property [templateDir]11:20:13,593 WARN com.opensymphony.xwork2.ognl.OgnlValueStack:46 - Could not find property [theme]11:20:13,593 WARN com.opensymphony.xwork2.ognl.OgnlValueStack:46 - Could not find property [theme]11:20:13,593 WARN com.opensymphony.xwork2.ognl.OgnlValueStack:46 - Could not find property [templateDir]11:20:13,593 WARN com.opensymphony.xwork2.ognl.OgnlValueStack:46 - Could not find property [templateDir]11:20:13,593 WARN com.opensymphony.xwork2.ognl.OgnlValueStack:46 - Could not find property [theme]11:20:13,609 WARN com.opensymphony.xwork2.ognl.OgnlValueStack:46 - Could not find property [theme]11:20:13,781 WARN com.opensymphony.xwork2.ognl.OgnlValueStack:46 - Could not find property [struts.valueStack] 问题补充：我加了没有用。langshao 写道

解决方案

把 log4j.rootLogger=warn, stdout 改为 log4j.rootLogger=error, stdout先试一下 log4j.properties 是否起作用.
解决方案二：
对了你被忘了在action中也得调用ActionSupport.add方法
解决方案三：
引用果然还是没有用。把整个log4j.properties贴出来看看，注意这个文件是放在WEB-INF/classes目录下。
解决方案四：
在struts2中出现Could not find property [struts.valueStack] 的原因就是没有引入log4j.jar的问题引入log4j.jar在log4j.properties 加入log4j.logger.com.opensymphony.xwork2=ERROR或者在log4.xml加入<category name="com.opensymphony.xwork2.ognl.OgnlValueStack"> <priority value="error"/> </category> 提高log4j的级别。没有其他办法了。
解决方案五：
引用我重启了，怎么备份清空日志我就不知道了。怎么做呀？选停了，然后将当前日志文件改个名，然后启动。
解决方案六：
引用我加了没有用。不要忘了重启，并备份清空日志（以免看错了）。
解决方案七：
Missing PropertiesThis message states that the framework searched for a property in the value stack and failed to find it.2008-04-19 14:21:08,177 WARN [http-8443-Processor25] [OgnlValueStack] Could not find property [templateDir]2008-04-19 14:21:08,177 WARN [http-8443-Processor25] [OgnlValueStack] Could not find property [templateDir]2008-04-19 14:21:08,177 WARN [http-8443-Processor25] [OgnlValueStack] Could not find property [templateDir]2008-04-19 14:21:08,178 WARN [http-8443-Processor25] [OgnlValueStack] Could not find property [org.apache.catalina.jsp_file]To hide these messages, turn off the WARN level logging for OgnlValueStack.eg. Include a new limit category in your log4j.xml file (only log errors or worse):<category name="com.opensymphony.xwork2.ognl.OgnlValueStack"> <priority value="error"/> </category>原来是少了log4j配置文件，顿悟+无语。。。。。看一下lib包，果然没有log4j-xxx.jar,到apache下个log4j- 1.2.9.jar包放到lib下。现在不需要写log4.xml也不会出现警告信息。如果加上去也可以，把日志信息的级别调整为ERRORJ即可。
解决方案八：
删了log4j.properties是不行的，在log4j.properties中加入一行就看不见了：log4j.logger.com.opensymphony.xwork2.ognl=ERROR
