springboot三种获取request和response的方法

原文链接：https://blog.youkuaiyun.com/mastertojava/article/details/85088421

方式一:

ServletRequestAttributes servletRequestAttributes = (ServletRequestAttributes)RequestContextHolder.getRequestAttributes();

HttpServletRequest request = servletRequestAttributes.getRequest();

HttpServletResponse response = servletRequestAttributes.getResponse();

方式二:

也可以在方法中可以注入,例如

public String center(HttpServletRequest request,HttpServletResponse response) {...}

方式三:

@Autowired
  private HttpServletRequest request;

普通类中获取session

HttpServletRequest request = ((ServletRequestAttributes) RequestContextHolder.getRequestAttributes()).getRequest();
        HttpSession session = request.getSession();
