Answer 1

使用此更改您的 servlet 映射并尝试；

<servlet-mapping>

    <servlet-name>appServlet</servlet-name>

    <url-pattern>/*</url-pattern>

</servlet-mapping>

在你的web.xml，你url-pattern的只是/ 。更改/*为向任何网址发送请求。

Answer 2

试试下面：

<servlet-mapping>

    <servlet-name>appServlet</servlet-name>

    <url-pattern>/app/*</url-pattern>

</servlet-mapping>
