爲什麼URL pattern/admin/*也匹配/ admin

Question

我正在使用JBOSS AS 7，並且我注意到一個奇怪的行爲，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> 

當我用膠帶將以下網址/admin我重定向到這是正常的CAS服務器，在那之後我重定向到ScomIHMServlet，並這是一部分，我錯過了所有這些過程，/ admin與/ admin/*不匹配，所以這怎麼能實現呢？對不起，很長的web.xml文件，我試圖發佈它的最重要的部分，任何建議將apreciated。

Answer 1

您應該將/admin解釋爲一個文件夾。

如果它理論上是一個文件，那麼它確實不匹配。

如果它是一個文件夾，那麼您應該將實際URL解釋爲/admin/。當然這匹配/admin/*，因爲*表示「零個或多個字符」。
