struts2出现的漏洞以及影响:

项目中的struts版本是struts2.0.11,要求升级到目前最新的版本struts2.3.15.2。
工程修改内容:
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
工程中需删除的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
升级过程中遇到的问题及其解决办法:
1. - Cannot reduce the visibility of the inherited method from ExceptionMappingInterceptor
【将ExceptionLogger类,由于继承了ExceptionMappingInterceptor并且重写了findResultFromExceptions(List exceptionMappings, Throwable t) 方法, 父类该方法的作用域是protected,所以子类必须将原来的private修改为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中将struts2 prepare filter放到cas filter前面,将struts executer filter放到cas filter后面
这样配置之后,启动服务器后重新访问bcec url,形如:http: // localhost:8080/bcec/zoneAction!initZone.action?function=zone 不会出现自动不转向到cas然后登陆的情况。
因为CasFilter.java过滤器中获取了ActionContext对象,但是此时如果先走这个filter的话Struts还没有初始化,所有ActionContext对象为null。
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,删除原来的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"/> 增加该项表示开启动态方法调用(形如:XXAction!xxx.action)。struts2.3.15.2版本中默认为false(不支持动态方法调用),而struts2.0.11中默认值是true(支持动态方法调用)】
这个耗费了多些时间,跟踪了下源码.
6.java.lang.ClassNotFoundException: com.opensymphony.xwork2.util.TextUtils
【新增struts2-json-plugin-2.3.15.2.jar,删除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" /> 将value修改为false或者将该条配置去掉。】

\--------------------------------------/
解决方式:
【在strurts.xml的拦截器中覆盖struts2的默认拦截器栈,并在params方法中过滤掉相应的请求参数(正则表达式编写),这样就可以屏蔽OGNL表达式的解析。

<!-- Rest接口使用,解决【hostId.1】这类请求参数出现OGNL解析异常问题 -->
<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文件中引用上述拦截器:
<package name="query" namespace="/query" extends="default">
<action name="instancesAction" class="instancesAction">
<interceptor-ref name="li"/>
<interceptor-ref name="fixDefaultStack"></interceptor-ref>
</action>
... ...
</package>
