    struts2出現(xiàn)的漏洞以及影響：
    http://www.iteye.com/news/28053#comments

    http://baike.baidu.com/link?url=6-45Efjxfsz2J74shu4sfd9G4ASrYig3ovFgBZASXbYGhGXeB368Glur39lakBEmntTDl_EIHro78o0tcyoCcK

    項(xiàng)目中的struts版本是struts2.0.11，要求升級(jí)到目前最新的版本struts2.3.15.2。
    工程修改內(nèi)容：
        新增的jar包：
            struts2-core-2.3.15.2.jar
            struts2-spring-plugin-2.3.15.2.jar
            struts2-json-plugin-2.3.15.2.jar
            xwork-core-2.3.15.2.jar
            ognl-3.0.6.jar
            javassist-3.11.0.GA
            commons-lang3-3.1.jar
        配置文件修改：
            web.xml
            struts.xml
        Java文件修改：
        ExceptionLogger.java

    工程中需刪除的jar包：
    struts-core-2.0.11.jar
    struts-spring-plugin-2.0.11.jar
    xwork-2.0.4.jar
    jsonplugin-0[1].32.jar

    升級(jí)過(guò)程中遇到的問(wèn)題及其解決辦法:
    1. - Cannot reduce the visibility of the inherited method from ExceptionMappingInterceptor
     【將ExceptionLogger類(lèi)，由于繼承了ExceptionMappingInterceptor并且重寫(xiě)了findResultFromExceptions(List exceptionMappings, Throwable t) 方法, 父類(lèi)該方法的作用域是protected，所以子類(lèi)必須將原來(lái)的private修改為protected或者public】
    2.java.lang.NullPointerException
        edu.yale.its.tp.cas.client.filter.CASFilter.doFilter(CASFilter.java:409)
        com.ccms.base.filter.EncodingFilter.doFilter(EncodingFilter.java:53)
     【
        web.xml中將struts2 prepare filter放到cas filter前面，將struts executer filter放到cas filter后面
        這樣配置之后，啟動(dòng)服務(wù)器后重新訪(fǎng)問(wèn)bcec url，形如：http://localhost:8080/bcec/zoneAction!initZone.action?function=zone 不會(huì)出現(xiàn)自動(dòng)不轉(zhuǎn)向到cas然后登陸的情況。
        因?yàn)镃asFilter.java過(guò)濾器中獲取了ActionContext對(duì)象，但是此時(shí)如果先走這個(gè)filter的話(huà)Struts還沒(méi)有初始化，所有ActionContext對(duì)象為null。
        
    <filter>
            <filter-name>struts-prepare</filter-name>

            <url-pattern>/*</url-pattern>
        </filter-mapping>
       】
    3. Caused by java.lang.ClassNotFoundException javassist.ClassPool
      【新增javassist-3.11.0.GA.jar】
    4. java.lang.NoSuchMethodError: ognl.SimpleNode.isEvalChain(Lognl/OgnlContext;)
      【OGNL包不兼容，刪除原來(lái)的ognl-2.6.11.jar，新增ognl-3.0.6.jar】
    5. HTTP Status 404 - There is no Action mapped for namespace [/] and action name [loginAction!login] associated with context path [/bcec].
      【<constant name="struts.enable.DynamicMethodInvocation" value="true"/> 增加該項(xiàng)表示開(kāi)啟動(dòng)態(tài)方法調(diào)用（形如：XXAction!xxx.action）。struts2.3.15.2版本中默認(rèn)為false（不支持動(dòng)態(tài)方法調(diào)用），而struts2.0.11中默認(rèn)值是true（支持動(dòng)態(tài)方法調(diào)用）】     
       這個(gè)耗費(fèi)了多些時(shí)間，跟蹤了下源碼.
    6.java.lang.ClassNotFoundException: com.opensymphony.xwork2.util.TextUtils
      【新增struts2-json-plugin-2.3.15.2.jar，刪除jsonplugin-0.3x.jar包】
    7.Caused by: No object in the CompoundRoot has a publicly accessible property named 'datetime' (no setter could be found). - [unknown location]
      【<constant name="struts.devMode" value="false" /> 將value修改為false或者將該條配置去掉。】  
    8. [2013-10-15 18:11:48] [WARN ] Error setting expression 'struts.token.name' with value '[Ljava.lang.String;@14057e5' - at com.opensymphony.xwork2.util.logging.commons.CommonsLogger.warn(CommonsLogger.java:64) 
    ognl.OgnlException: source is null for getProperty(null, "token")
    【struts.xml中修改params參數(shù)攔截器配置如下：
    <interceptor-ref name="params">
    					<param name="excludeParams">
    						dojo\..*,.*\\u0023.*,struts.token,struts.token.name
    					</param>
    </interceptor-ref>
    】
    9. [2013-10-16 10:38:19] [WARN ] Could not find token name in params. - at com.opensymphony.xwork2.util.logging.commons.CommonsLogger.warn(CommonsLogger.java:56) 
    【struts.xml中修改token攔截器中增加對(duì)防止重復(fù)提交方法的攔截配置：
    <interceptor-ref name="token">
    					<param name="includeParams">
                                                      allocate,create
    					</param>
    </interceptor-ref>
    】
    10. 當(dāng)rest接口發(fā)送請(qǐng)求參數(shù)格式形如：hostId.1、hostId.2....
    后臺(tái)會(huì)遇到ognl解析錯(cuò)誤，警告級(jí)錯(cuò)誤如下，很眼暈啊 ~~.

    解決方式：
    【在strurts.xml的攔截器中覆蓋struts2的默認(rèn)攔截器棧，并在params方法中過(guò)濾掉相應(yīng)的請(qǐng)求參數(shù)（正則表達(dá)式編寫(xiě)），這樣就可以屏蔽OGNL表達(dá)式的解析。
    <interceptor-stack name="fixDefaultStack">
    	                <interceptor-ref name="exception"/>
    	                <interceptor-ref name="alias"/>
    	                <interceptor-ref name="servletConfig"/>
    	                <interceptor-ref name="i18n"/>
    	                <interceptor-ref name="prepare"/>
    	                <interceptor-ref name="chain"/>
    	                <interceptor-ref name="scopedModelDriven"/>
    	                <interceptor-ref name="modelDriven"/>
    	                <interceptor-ref name="fileUpload"/>
    	                <interceptor-ref name="checkbox"/>
    	                <interceptor-ref name="multiselect"/>
    	                <interceptor-ref name="staticParams"/>
    	                <interceptor-ref name="actionMappingParams"/>
    	                <interceptor-ref name="params">
    	                    <!-- Rest接口使用，解決【hostId.1】這類(lèi)請(qǐng)求參數(shù)出現(xiàn)OGNL解析異常問(wèn)題 -->
    	                    <param name="excludeParams">
    	                    	dojo\..*,^struts\..*,^session\..*,^request\..*,^application\..*,^servlet(Request|Response)\..*,parameters\...*,
    	                    	^zoneId\..*, ^clusterId\..*, ^hostId\..*, ^instanceId\..*,
    	                    </param>
    	                </interceptor-ref>
    	                <interceptor-ref name="conversionError"/>
    	                <interceptor-ref name="validation">
    	                    <param name="excludeMethods">input,back,cancel,browse</param>
    	                </interceptor-ref>
    	                <interceptor-ref name="workflow">
    	                    <param name="excludeMethods">input,back,cancel,browse</param>
    	                </interceptor-ref>
    	                <interceptor-ref name="debugging"/>
    	        </interceptor-stack>
    再在struts-query.xml配置的Action文件中引用上述攔截器：
    <package name="query" namespace="/query" extends="default">
    		<action name="instancesAction" class="instancesAction">
    			<interceptor-ref name="li"/>
    	        <interceptor-ref name="fixDefaultStack"></interceptor-ref>
    		</action>
    ... ...
    </package>

    樓主這個(gè)問(wèn)題見(jiàn)過(guò)沒(méi)：
    通過(guò)頁(yè)面按鈕action手動(dòng)啟動(dòng)調(diào)度job是可以取到資源文件的內(nèi)容的，可以正常跑該任務(wù)。但spring代理調(diào)度該job時(shí)無(wú)法取得properties的資源文件，struts2.3出現(xiàn)此問(wèn)題，struts2.0的版本沒(méi)問(wèn)題。
