java - Liferay portlet 中的自定义 servlet/jsp

Question

我记得可以将类似这样的内容添加到 portlet 的 web.xml 中，并且可以在 http://host:8080/abcd/hw 访问 jsp 或 servlet。 ....

<servlet>
    <servlet-name>myjsp</servlet-name>
    <jsp-file>/index.jsp</jsp-file>
    <init-param>
        <param-name>hello</param-name>
        <param-value>test</param-value>
    </init-param>
</servlet>
<servlet>
    <servlet-name>myServlet</servlet-name>
    <servlet-class>com.example.Servlet</servlet-class>
</servlet>

<servlet-mapping>
    <servlet-name>myjsp</servlet-name>
    <url-pattern>/jsp/*</url-pattern>
</servlet-mapping>

<servlet-mapping>
    <servlet-name>myServlet</servlet-name>
    <url-pattern>/abcd/hw</url-pattern>
    <load-on-startup>1</load-on-startup>
</servlet-mapping>

但现在它有点解析为

INFO  [PortalImpl:4243] Current URL /abcd/hw generates exception: null

好像是被过滤掉了之类的，但是调试的时候什么都没发现。

我在这里闻到了问题

只有一条信息是你不知道的。

URL 将是 http://host:8080/cool-portlet/abcd/hw ....

如果您正在请求一个 servlet，'web-context' 目录名称必须跟在 ...

webapp/
    cool-portlet/
    ROOT/
