Java中如何获取HttpServletRequest、HttpServletResponse呢?

下文笔者讲述Spring开发中获取HttpServletRequest、HttpServletResponse的方法及示例分享,如下所示

获取HttpServletRequest、HttpServletResponse的几种方式

1.可封装为静态方法

ServletRequestAttributes servletRequestAttributes =  (ServletRequestAttributes)RequestContextHolder.getRequestAttributes();
HttpServletRequest request = servletRequestAttributes.getRequest();
HttpServletResponse response = servletRequestAttributes.getResponse();

2.controller中获取request和response的方法

@GetMapping(value = "")
public String doSomething(HttpServletRequest request,HttpServletResponse response) {
    //...
}

3.直接注入

@Autowired
private HttpServletRequest request;
@Autowired
private HttpServletResponse response;
