java - 在带有 spring 的 jsp 页面中包含样式表

Question

我无法从 jsp 页面链接到样式表。我不知道出了什么问题。这是我的目录结构:

|
|-- WEB-INF
|     |
|     |-- jsp
|          |-- index.jsp
|
|-- resources
      |
      |-- css
           |-- style.css

我试过这样做

<link rel="stylesheet" type="text/css" href="/resources/css/style.css" />

这是我的 web.xml

<welcome-file-list>
    <welcome-file>index.jsp</welcome-file>
</welcome-file-list>
<servlet>
    <servlet-name>spring</servlet-name>
    <servlet-class>
        org.springframework.web.servlet.DispatcherServlet
    </servlet-class>
    <load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
    <servlet-name>spring</servlet-name>
    <url-pattern>/</url-pattern>
</servlet-mapping>

请帮助我做错什么，我们将不胜感激。

提前致谢

当您使用 url“/”映射您的 spring-servlet(Spring) 时，所有请求都将重定向到 Spring-servlet。也包括 .css 和 .js 等。

虽然您找到了解决方案，但我为您提供了我使用过的另一种选择。

<servlet>
    <servlet-name>dispatcher</servlet-name>
    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
  </servlet>

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

  <servlet>
    <servlet-name>static</servlet-name>
    <servlet-class>StaticServlet</servlet-class>
  </servlet>

      <servlet-mapping>
        <servlet-name>static</servlet-name>
        <url-pattern>/images/*</url-pattern>
        <url-pattern>/css/*</url-pattern>
        <url-pattern>/img/*</url-pattern>
        <url-pattern>/js/*</url-pattern>
        <url-pattern>/swf/*</url-pattern>
      </servlet-mapping>

为资源提供服务的静态 Servlet

import java.io.FileInputStream;
import java.io.IOException;

import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

import org.apache.commons.io.IOUtils;

public class StaticServlet extends HttpServlet {

    private static final long serialVersionUID = 8458501870440200891L;

    @Override
    protected void doGet(HttpServletRequest req, HttpServletResponse resp)
            throws ServletException, IOException {
        String resourcePath = req.getServletPath() + req.getPathInfo();
        String realPath = getServletContext().getRealPath(resourcePath);
        FileInputStream fileInputStream = new FileInputStream(realPath);
        try {
            IOUtils.copy(fileInputStream, resp.getOutputStream());
        } finally {
            fileInputStream.close();
        }
    }

}
