import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpSession;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RestController;

@RestController
public class MyController {
    
    @Autowired
    private HttpServletRequest request;
    
    @Autowired
    private HttpSession session;
    
    @GetMapping("/example")
    public String example() {
        // 使用request和session对象进行操作
        String sessionId = session.getId();
        String userAgent = request.getHeader("User-Agent");
        
        // 返回响应
        return "Session ID: " + sessionId + ", User Agent: " + userAgent;
    }
}
