Session
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpSession;
import org.springframework.web.bind.annotation.CrossOrigin;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.web.bind.annotation.RestController;
@RestController
@RequestMapping("/test")
@CrossOrigin
public class HelloSessionController {
@RequestMapping("/add")
public String addSession(HttpServletRequest httpServletRequest,
@RequestParam("username")String username) {
HttpSession session = httpServletRequest.getSession();
session.setAttribute("username",username);
session.setMaxInactiveInterval(10000);
return "添加成功";
}
@RequestMapping("/show")
public Object showSession(HttpServletRequest httpServletRequest) {
HttpSession session = httpServletRequest.getSession();
Object object = session.getAttribute("username");
return object;
}
}
Cookie
import javax.servlet.http.Cookie;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.web.bind.annotation.RestController;
@RestController
@RequestMapping("/cookie")
public class HelloCookieController {
@RequestMapping("/add")
public String addCookie(HttpServletRequest request,HttpServletResponse response,
@RequestParam("username")String username) {
Cookie cookie = new Cookie("username", username);
cookie.setPath(request.getContextPath());
cookie.setMaxAge(80000);
response.addCookie(cookie);
return "添加成功";
}
@RequestMapping("/show")
public String showCookie(HttpServletRequest request) {
Cookie[] cookies = request.getCookies();
for (Cookie cookie : cookies) {
if(cookie.getName().equals("username")) {
System.out.println(cookie.getName());
System.out.println(cookie.getValue());
return cookie.getValue().toString();
}
}
return "null";
}
}
