1. 将背景图片放置在webapp目录下的某个文件夹中,如webapp/images/background.jpg。
2. 在web.xml文件中添加以下代码:
```
<servlet>
<servlet-name>background</servlet-name>
<servlet-class>com.example.BackgroundServlet</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>background</servlet-name>
<url-pattern>/background</url-pattern>
</servlet-mapping>
```
3. 创建BackgroundServlet类,代码如下:
```
package com.example;
import java.io.IOException;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
public class BackgroundServlet extends HttpServlet {
protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
response.setContentType("text/html");
response.getWriter().println("<html><head><style>body { background-image: url(images/background.jpg); }</style></head><body></body></html>");
}
}
```
4. 在jsp页面中通过以下代码引用背景图片:
```
<body style="background-image: url(background)">
```
其中,background为Servlet的url-pattern。
