解决com.alibaba.fastjson.JSONException: write javaBean error, fastjson version 1.2.83

com.alibaba.fastjson.JSONException: write javaBean error, 
fastjson version 1.2.83, 
class org.springframework.web.multipart.support.StandardMultipartHttpServletRequest, 
method : getAsyncContext复制

在日志中，Fastjson似乎试图将StandardMultipartHttpServletRequest序列化为JSON这可能是因为HttpServletRequest被错误地传递给了Fastjson，而不是MultipartFile

查看代码 

@RequestMapping(value = "/importInfoExcel")
 
    public String importInfoExcel(HttpServletRequest httpServletRequest,HttpServletResponse httpServletResponse,MultipartFile multipartFile) {
 
        String retmesg = "";
        try {
            logger.info("importInfoExcel-----");
 
            EasyExcel.read(multipartFile.getInputStream(), OrgUser.class,new DataList(wlwService)).sheet().doRead();
 
            retmesg = "{\"code\":1,\"desc\":\"导入完成\"}";
            return retmesg;
        } catch (Exception e) {
            return "{\"code\":-1,\"desc\":\"导入失败\"}";
        }复制

         看到问题可能出现在尝试将MultipartFile转换为JSON时具体来说，Fastjson库在尝试序列化HttpServletRequest对象时可能遇到了问题。要解决这个问题，需要确保只将MultipartFile对象传递给Fastjson。所以删除HttpServletRequest和HttpServletResponse参数就行了。
