我的大约30个重写链接工作正常,但我有一些在第一次被调用时无法工作,但他们第二次工作!
这是web.xml片段:
<filter>
<filter-name>struts2</filter-name>
<filter-class>org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter</filter-class>
<init-param>
<param-name>actionPackages</param-name>
<param-value>uk.co.prodia.prosoc.struts2.action</param-value>
</init-param>
</filter>
<filter>
<filter-name>UrlRewriteFilter</filter-name>
<filter-class>org.tuckey.web.filters.urlrewrite.UrlRewriteFilter</filter-class>
</filter>
<filter-mapping>
<filter-name>UrlRewriteFilter</filter-name>
<url-pattern>/*</url-pattern>
<dispatcher>REQUEST</dispatcher>
<dispatcher>FORWARD</dispatcher>
</filter-mapping>
<filter-mapping>
<filter-name>struts2</filter-name>
<url-pattern>/*</url-pattern>
<dispatcher>REQUEST</dispatcher>
<dispatcher>FORWARD</dispatcher>
</filter-mapping>
这是urlrewrite.xml,它第一次调用时会给出404:
<rule>
<from>^/forgotten-password$</from>
<to>/unsecured/forgotten-password!input.action</to>
</rule>
和struts2配置该操作:
<package name="unsecured" extends="struts-default" namespace="/unsecured">
<action name="forgotten-password" class="actionForgottenPassword">
<result name="input">/WEB-INF/view/unsecured/forgotten-password.jsp</result>
<result name="passwordNotFound">/WEB-INF/view/unsecured/forgotten-password.jsp</result>
</action>
</package>
但是,如果我让urlrewrite.xml通过包含unsecured
操作的forgotten-password
包,那么它可以正常工作:
<rule>
<from>^/unsecured/forgotten-password$</from><!--works through /unsecured -->
<to>/unsecured/forgotten-password!input.action</to>
</rule>
似乎从urlrewrite中缺少Struts2包名会在第一次使用URI时导致404。
这对任何人都有意义,还是我只能留在疯狂的城镇?
答案 0 :(得分:1)
问题似乎是由上下文第一页加载中的URL中的jsessionid引起的。我对regexp有点无用,但这似乎有效:
<rule>
<from>^/forgotten-password(;jsessionid=.*)?$</from>
<to>/unsecured/forgotten-password!input.action</to>
</rule>
我将(;jsessionid=.*)?
添加到每个规则的末尾,似乎有效。
