servlet url-pattern /与/*的区别

Question

它们之间的区别是什么：

<servlet-mapping>
        <servlet-name>dispatcher</servlet-name>
        <url-pattern>/</url-pattern>
</servlet-mapping>

和：

<servlet-mapping>
        <servlet-name>dispatcher</servlet-name>
        <url-pattern>/*</url-pattern>
</servlet-mapping>

Answer 1

/只与根ie匹配。http://yourserver/webapplication/。/*匹配命中应用程序http://yourserver/webapplication/和http://yourserver/webapplication/any/path/you/want的所有请求

Answer 2

<servlet-mapping>
    <servlet-name>dispatcher</servlet-name>
    <url-pattern>/</url-pattern>
</servlet-mapping>

将http://server.local/your-application/映射到dispatcher servlet

<servlet-mapping>
    <servlet-name>dispatcher</servlet-name>
    <url-pattern>/*</url-pattern>
</servlet-mapping>

将http://server.local/your-application/%ANYTHING%映射到dispatcher servlet
