spring boot如何开启session会话存取数据？
网友回复
可以通过HttpServletRequest与HttpServletResponse来设置session，代码如下：
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.*;
import org.springframework.web.servlet.ModelAndView;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import java.net.http.HttpResponse;
@Controller
public class HelloController {
@RequestMapping("/hello")
@ResponseBody
public String index(HttpServletRequest req, HttpServletResponse rep) {
String id = req.getSession().getId();//jsessionid存储到浏览器的COOKIE名字
String islogined= (String) req.getSession().getAttribute("bfw");
if(islogined==null){
req.getSession().setAttribute("bfw","dd");
return "guest "+id;
}else{
return "logined "+id;
}
}
}
