1、通过Springboot程序可以发现，Springboot中控制器的形式和Springmvc中是一样的，因此在程序中使用jsp的内置对象也可以按照与Springmvc同样的方式进行。
代码语言：javascript复制 1 package org.springboot.tentent.controller;
2
3 import java.util.HashMap;
4 import java.util.Map;
5
6 import javax.servlet.http.HttpServletRequest;
7 import javax.servlet.http.HttpServletResponse;
8
9 import org.springframework.web.bind.annotation.RequestMapping;
10 import org.springframework.web.bind.annotation.RestController;
11
12 @RestController
13 public class SampleController {
14
15 @RequestMapping(value = "/hello")
16 public Map<String, String> hello(HttpServletRequest httpServletRequest, HttpServletResponse httpServletResponse) {
17 Map<String, String> map = new HashMap<String, String>();
18 map.put("客户端的ip地址： ", httpServletRequest.getRemoteAddr());
19 map.put("客户端的响应编码： ", httpServletResponse.getCharacterEncoding());
20 map.put("客户端的SessionID： ", httpServletRequest.getSession().getId());
21 map.put("项目的真实路径： ", httpServletRequest.getServletContext().getRealPath("/"));
22 return map;
23 }
24
25 }访问如下所示：
除了在控制器的方法上使用参数来接收内置对象外，也可以利用ServletRequestAttributes形式来获取内置对象。

31 .getRequest();
32 // 获取HttpServletResponse内置对象
33 HttpServletResponse httpServletResponse = ((ServletRequestAttributes) RequestContextHolder
34 .getRequestAttributes()).getResponse();

39 map.put("项目的真实路径： ", httpServletRequest.getServletContext().getRealPath("/"));
40 return map;
41 }
