Answer 2

If it is servlet的话，那简简单单一个filter, it can be done, and someone has already done it, just use it: cors-filter.

If your problem is that you don’t understand cross-domain, then you have to read: Building public APIs and CORS

Answer 3

public class CorsConfigurerAdapter extends WebMvcConfigurerAdapter{

  @Override
  public void addCorsMappings(CorsRegistry registry) {
    
    registry.addMapping("/api/*").allowedOrigins("*");
  }
}
