    urlbasedcorsconfigurationsource source = new urlbasedcorsconfigurationsource();
    corsconfiguration config = new corsconfiguration();
    config.setallowcredentials(true);
    // 设置你要允许的网站域名,如果全允许则设为 *
    config.addallowedorigin("http://localhost:4200");
    // 如果要限制 header 或 method 请自行更改
    config.addallowedheader("*");
    config.addallowedmethod("*");
    source.registercorsconfiguration("/**", config);
    filterregistrationbean bean = new filterregistrationbean(new corsfilter(source));
    // 这个顺序很重要哦,为避免麻烦请设置在最前
    bean.setorder(0);
    return bean;
  }
}
