• RequestContextHolder顾名思义，持有上下文的Request容器。可以用来获取当前请求信息

package com.repository.manage.config;

import lombok.extern.slf4j.Slf4j;
import org.springframework.web.context.request.RequestContextHolder;
import org.springframework.web.context.request.ServletRequestAttributes;

import javax.servlet.http.HttpServletRequest;

/**
* 获取当前请求信息

@Slf4j
public class Current {
    public static HttpServletRequest getRequest() {
        ServletRequestAttributes attributes = (ServletRequestAttributes) RequestContextHolder.getRequestAttributes();
        assert attributes != null;
        return attributes.getRequest();
    }
}
