程序启动后日志：
23-Jul-2016 14:05:35.050 WARNING [http-apr-8080-exec-2] org.springframework.web.servlet.PageNotFound.noHandlerFound No mapping found for HTTP request with URI [/dps/WEB-INF/views/index.jsp] in DispatcherServlet with name 'dps'

web根目录变成了/dps/WEB-INF而不是/WEB-INF ?????????

Answer 1

在web.xml中把url-pattern改成/就行了

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

Answer 2

這是我以前寫的一個hello world小demo。 https://github.com/HelloListe...

另外，建議使用spring boot。

Answer 3

web-inf 是看不見的，需要內部跳轉，你或把這個jsp提出來，或是自己在jsp上寫一個redirect
