SpringBoot中如何获取HttpServletRequest呢?

HttpServletRequest获取方法

方式1:
   Controller方法写上HttpServletRequest类型的参数即可接收对应的HttpServletRequest
   如:
		@GetMapping("/test")
		public void test(HttpServletRequest request) {}

方式2:
    从RequestContextHolder上下文获取
    如:
	// 从请求上下文里获取Request对象
	ServletRequestAttributes requestAttributes = ServletRequestAttributes.class.
        cast(RequestContextHolder.getRequestAttributes());
    HttpServletRequest contextRequest = requestAttributes.getRequest(); 

方式3:
   依赖注入@Autowired
	@Autowired
	HttpServletRequest req; 

@GetMapping("/test")
public void test(HttpServletRequest request) {

}
