Method 3: Set the correct css path

(1) If your .jsp file is outside the WEB-INF folder, you can use a relative path

(2) If your .jsp file is in the WEB-INF folder, you must use the absolute path and add this ${pageContext.request.contextPath}

Method 4: Set the filter to intercept the request path to the corresponding file. For example, I filter jsp files, so my xml part is configured as follows:

<filter-mapping>
    <filter-name>login</filter-name>
     <url-pattern>/.jsp</url-pattern>
</filter-mapping>
