为什么URL pattern/admin/*也匹配/ admin

Question

我正在使用JBOSS AS 7，并且我注意到一个奇怪的行为，涉及到servlet映射。

我的web.xml：

<context-param> 
    <param-name>APPLICATION_NAME</param-name> 
    <param-value>scom</param-value> 
</context-param> 

<servlet> 
    <servlet-name>admin</servlet-name> 
    <servlet-class>com.afp.iris.sr.sco.scom.servlet.ScomIHMServlet</servlet-class> 
</servlet> 
<servlet-mapping> 
    <servlet-name>admin</servlet-name> 
    <url-pattern>/admin/*</url-pattern> 
</servlet-mapping> 
<servlet> 
    <servlet-name>Resteasy</servlet-name> 
    <servlet-class>org.jboss.resteasy.plugins.server.servlet.HttpServletDispatcher</servlet-class> 
    <init-param> 
     <param-name>resteasy.scan</param-name> 
     <param-value>true</param-value> 
    </init-param> 
</servlet> 
<servlet-mapping> 
    <servlet-name>Resteasy</servlet-name> 
    <url-pattern>/*</url-pattern> 
</servlet-mapping> 
<filter-mapping> 
    <filter-name>IrisFilter</filter-name> 
    <url-pattern>/*</url-pattern> 
</filter-mapping> 
<filter> 
    <filter-name>CAS Single Sign Out Filter</filter-name> 
    <filter-class>org.jasig.cas.client.session.SingleSignOutFilter</filter-class> 
    <init-param> 
     <param-name>artifactParameterName</param-name> 
     <param-value>SAMLart</param-value> 
    </init-param> 
</filter> 

<filter-mapping> 
    <filter-name>CAS Single Sign Out Filter</filter-name> 
    <url-pattern>/*</url-pattern> 
</filter-mapping> 

<listener> 
    <listener-class>org.jasig.cas.client.session.SingleSignOutHttpSessionListener</listener-class> 
</listener> 

<filter> 
    <filter-name>CAS Authentication Filter</filter-name> 
    <filter-class>org.jasig.cas.client.authentication.Saml11AuthenticationFilter</filter-class> 
    <init-param> 
     <param-name>casServerLoginUrl</param-name> 
     <param-value>${cas.server.url.login}</param-value> 
    </init-param> 
    <init-param> 
     <param-name>serverName</param-name> 
     <param-value>${COMPONENT_HOST_URL}</param-value> 
    </init-param> 
</filter> 

<filter-mapping> 
    <filter-name>CAS Authentication Filter</filter-name> 
    <url-pattern>/admin</url-pattern> 
</filter-mapping> 

<filter> 
    <filter-name>CAS Validation Filter</filter-name> 
    <filter-class>org.jasig.cas.client.validation.Saml11TicketValidationFilter</filter-class> 
    <init-param> 
     <param-name>casServerUrlPrefix</param-name> 
     <param-value>${cas.server.url.prefix}</param-value> 
    </init-param> 
    <init-param> 
     <param-name>serverName</param-name> 
     <param-value>${COMPONENT_HOST_URL}</param-value> 
    </init-param> 
    <init-param> 
     <param-name>redirectAfterValidation</param-name> 
     <param-value>true</param-value> 
    </init-param> 
    <init-param> 
     <param-name>useSession</param-name> 
     <param-value>true</param-value> 
    </init-param> 
    <init-param> 
     <param-name>acceptAnyProxy</param-name> 
     <param-value>true</param-value> 
    </init-param> 
    <init-param> 
     <param-name>tolerance</param-name> 
     <param-value>${cas.tolerance}</param-value> 
    </init-param> 
</filter> 
<filter-mapping> 
    <filter-name>CAS Validation Filter</filter-name> 
    <url-pattern>/admin</url-pattern> 
</filter-mapping> 

<filter> 
    <filter-name>CAS HttpServletRequest Wrapper Filter</filter-name> 
    <filter-class>org.jasig.cas.client.util.HttpServletRequestWrapperFilter</filter-class> 
</filter> 

<filter-mapping> 
    <filter-name>CAS HttpServletRequest Wrapper Filter</filter-name> 
    <url-pattern>/admin</url-pattern> 
</filter-mapping> 

<filter> 
    <filter-name>CAS Assertion Thread Local Filter</filter-name> 
    <filter-class>org.jasig.cas.client.util.AssertionThreadLocalFilter</filter-class> 
</filter> 

<filter-mapping> 
    <filter-name>CAS Assertion Thread Local Filter</filter-name> 
    <url-pattern>/*</url-pattern> 
</filter-mapping> 

当我用胶带将以下网址/admin我重定向到这是正常的CAS服务器，在那之后我重定向到ScomIHMServlet，并这是一部分，我错过了所有这些过程，/ admin与/ admin/*不匹配，所以这怎么能实现呢？对不起，很长的web.xml文件，我试图发布它的最重要的部分，任何建议将apreciated。

Answer 1

您应该将/admin解释为一个文件夹。

如果它理论上是一个文件，那么它确实不匹配。

如果它是一个文件夹，那么您应该将实际URL解释为/admin/。当然这匹配/admin/*，因为*表示“零个或多个字符”。
