SpringBoot获取HttpServletRequest的3种方式总结

作者：太空眼睛

这篇文章主要给大家介绍了关于SpringBoot获取HttpServletRequest的3种方式,在Spring boot项目中经常要用到Servlet的常用对象如HttpServletRequest request,HttpServletResponse response,HttpSession session,需要的朋友可以参考下

方法一: Controller中增加request参数

@RestController
public class DemoController { 
    @RequestMapping("/demo")
    public void demo(HttpServletRequest request) {        
        System.out.println(request.getParameter("hello"));
    }
}

方法二: 自动注入

@Slf4j
@RequestMapping(path = "/request")
@RestController
public class DemoRequestController {
    @Resource
    private HttpServletRequest request1;
    @RequestMapping(path = "/demo")
    public String demo(HttpServletRequest request2) {
        log.info("request1: {}", request1.getClass());
        log.info("request2: {}", request2.getClass());
        return "Hello, world!";
    }
}

方法三: 基类中自动注入

本质与方法二类似

public class BaseController {   
   @Autowired 
   protected HttpServletRequest request;
}

方法四: 手动调用

@Slf4j
@RequestMapping(path = "/request")
@RestController
public class DemoRequestController {
    @Resource
    private HttpServletRequest request1;
    @RequestMapping(path = "/demo")
    public String demo(HttpServletRequest request2) {
        HttpServletRequest request3 = ((ServletRequestAttributes) (RequestContextHolder.currentRequestAttributes())).getRequest();
        log.info("request1: {}", request1.getClass());
        log.info("request2: {}", request2.getClass());
        log.info("request3: {}", request3.getClass());
        return "Hello, world!";
    }
}

总结

获取HttpServletRequest共有三种方式

建议使用继承来减少代码冗余

适合在非Bean中获取
