Springboot使用内置对象HttpServletRequest、HttpServletResponse
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。
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。
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 import org.springframework.web.context.request.RequestContextHolder; 12 import org.springframework.web.context.request.ServletRequestAttributes; 13 14 @RestController 15 public class SampleController { 16 17 @RequestMapping(value = "/hello") 18 public Map<String, String> hello(HttpServletRequest httpServletRequest, HttpServletResponse httpServletResponse) { 19 Map<String, String> map = new HashMap<String, String>(); 20 map.put("客户端的ip地址： ", httpServletRequest.getRemoteAddr()); 21 map.put("客户端的响应编码： ", httpServletResponse.getCharacterEncoding()); 22 map.put("客户端的SessionID： ", httpServletRequest.getSession().getId()); 23 map.put("项目的真实路径： ", httpServletRequest.getServletContext().getRealPath("/")); 24 return map; 25 } 26 27 @RequestMapping(value = "/hello2") 28 public Map<String, String> hello() { 29 // 获取HttpServletRequest内置对象 30 HttpServletRequest httpServletRequest = ((ServletRequestAttributes) RequestContextHolder.getRequestAttributes()) 31 .getRequest(); 32 // 获取HttpServletResponse内置对象 33 HttpServletResponse httpServletResponse = ((ServletRequestAttributes) RequestContextHolder 34 .getRequestAttributes()).getResponse(); 35 Map<String, String> map = new HashMap<String, String>(); 36 map.put("客户端的ip地址： ", httpServletRequest.getRemoteAddr()); 37 map.put("客户端的响应编码： ", httpServletResponse.getCharacterEncoding()); 38 map.put("客户端的SessionID： ", httpServletRequest.getSession().getId()); 39 map.put("项目的真实路径： ", httpServletRequest.getServletContext().getRealPath("/")); 40 return map; 41 } 42 43 }
访问如下所示：
