spring boot在普通方法中获取HttpServletRequest及其使用的方式

一、通过RequestContextHolder来获取HttpServletRequest，示例代码如下

public static AuthUser getUser(){ RequestAttributes requestAttributes= RequestContextHolder.getRequestAttributes(); ServletRequestAttributes servletRequestAttributes=(ServletRequestAttributes)requestAttributes; //获取http请求，这步是关键 HttpServletRequest httpServletRequest = servletRequestAttributes.getRequest(); //从请求属性中获取 Object user= httpServletRequest.getAttribute("SYSTEM_CURRENT_USER"); if(user!=null){ return (AuthUser) user; } //从请求头获取 String token=httpServletRequest.getHeader("TP-Auth"); if(StringUtils.isBlank(token)){ return new AuthUser(); } //如果不存在则从token中进行解析 Map<String, Object> tokenMap=JwtUtil.getTokenInform(token); AuthUser authUser=AuthUser.builder().userId(Long.valueOf(tokenMap.get("userId").toString())) .userName(tokenMap.get("userName").toString()) .userAccount(tokenMap.get("userAccount").toString()) .userType(Integer.valueOf(tokenMap.get("userType").toString())) .deptIds(tokenMap.get("userDeptIds").toString()) .roleIds(tokenMap.get("userRoleIds").toString()) .postIds(tokenMap.get("userPostIds").toString()) .tenantId(Long.valueOf(httpServletRequest.getHeader("tenantId"))) .build(); return authUser; }

二、关于自定义线程获取失败的问题，需要手动获取一下，示例程序如下：

//获取主线程的上下文 RequestAttributes context = RequestContextHolder.getRequestAttributes(); new Thread(()->{ if (context!=null){ //👌传递并且设置上下文 RequestContextHolder.setRequestAttributes(context); System.out.println("自定义线程"); AuthUser user1= AuthUserUtils.getUser(); System.out.println(user1); } }).start();
