发现项目中有设置过滤器，只要把过滤器放开就可以了

package com.xxxx.xxx.xxxxx.filter;

import com.cetc.epms.inner.base.pojo.vo.LoginContextStore;

        String authorization = request.getHeader("Authorization");
        if (request.getMethod().equals("OPTIONS")) {
            response.setStatus(HttpServletResponse.SC_OK);
        }
        String requestURI = request.getRequestURI();

        boolean isWhite = isWhiteList(requestURI);

                chain.doFilter(req, res);
            } else {
                responseError(response, "ticket无效或过期", 401);
                return;
            }
        }else {
            chain.doFilter(req, res);
        }
    }

        return true;
    }

        httpResponse.setHeader("Access-Control-Allow-Credentials", "true");

        writeResult(outputStream, msg, code);
    }

    private static void writeResult(ServletOutputStream outputStream,String msg,int code){
        JSONObject json = new JSONObject();
        try {
            json.put("msg",msg);
            json.put("code",code);
            outputStream.write(json.toString().getBytes());
            outputStream.flush();
        } catch (Exception e) {
            e.printStackTrace();
        }finally {
            //writer.close();
        }
    }

}
