SpringBoot ＋Shiro的WebUtils.issueRedirect() 问题

SpringBoot ＋Shiro　＋ vue 基于PathMatchingFilter的权限认证

1.这是当前用户没有访问权限，然后跳转对应URL:

public class URLPathMatchingFilter extends PathMatchingFilter {
    @Override
    protected boolean onPreHandle(ServletRequest request, ServletResponse response, Object mappedValue) throws Exception {
      log.info("当前用户没有访问接口" + requestAPI + "的权限");
      WebUtils.issueRedirect(request, response, "/authentication/unauthorized");
      // vue的devServer 配置　host: 'localhost',port: 8888,
      //  WebUtils.issueRedirect(request, response, "http://localhost:8888/api/authentication/unauthorized");
      return false;
｝

2.这是跳转异常处理

@Controller
@RequestMapping("/authentication")
public class Authentication {
    @ResponseBody
    @GetMapping(value = "/unauthorized")
    public Result unauthorized(){
        throw new UnauthorizedException();
    }
}

3.然后统一处理

@ExceptionHandler({UnauthorizedException.class})
@ResponseBody
 public Result unauthorizedExceptionHandler(UnauthorizedException e) {
     log.error("资源不允许访问!", e);
     return Result.error(ExceptionEnum.UNAUTHORIZED);
 }

４运行结果及报错内容
WebUtils.issueRedirect(request, response, "/authentication/unauthorized");
当是这样跳转的话，会报跨域问题的错误
Access to XMLHttpRequest at 'http://localhost:8081/authentication/unauthorized' (redirected from 'http://localhost:8888/api/admin/userManagement/basic/getUserById') from origin 'http://localhost:8888' has been blocked by CORS policy: Request header field access-control-allow-methods is not allowed by Access-Control-Allow-Headers in preflight response.
但是我跨域都已经配置好了，访问其他页面都正常，就是WebUtils.issueRedirect跳转会报跨域的问题。
5.我的解答思路和尝试过的方法
WebUtils.issueRedirect(request, response, "http://localhost:8888/api/authentication/unauthorized");
这是我尝试的解决办法，可以正常跳转到异常处理。但总感觉不怎么好，这是vue配置localhost:8888/api
6.我想要达到的结果
我想要WebUtils.issueRedirect(request, response, "/authentication/unauthorized");报跨域问题怎么解决，看有小伙伴遇到这种情况或者谁能解决？谢谢！
