java - 请问 /* 和 / 的区别是什么？

Question

例如我在搭建Spring MVC时，在web.xml中进行如下基本的配置。请问<url-pattern>/*</url-pattern>和<url-pattern>/</url-pattern>的区别是什么？谢谢。

    <servlet>
        <servlet-name>dispatcher</servlet-name>
        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
        <init-param>
            <param-name>contextConfigLocation</param-name>
            <param-value>classpath:applicationContext.xml</param-value>
        </init-param>
        <load-on-startup>1</load-on-startup>
    </servlet>

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

I have also been confused about this problem. I saw a discussion on csdn http://bbs.csdn.net/topics/390610045
If configured as /, springMVC will treat all .jsp.. as txt. The result is that the jsp source code is loaded directly in the browser
