[FIXED] Spring CorsFilter CorsConfiguration Allow Multiple origins

Issue

im working in spring projet where i want to allow multiple origins call my backen API. so far my config works only for one origin. and this is my code :

  @Bean
  public CorsFilter corsFilter() {

    UrlBasedCorsConfigurationSource source = new UrlBasedCorsConfigurationSource();
    CorsConfiguration config = new CorsConfiguration();

    config.addAllowedOriginPattern("myoriginone");
    config.addAllowedHeader("*");
    config.addAllowedMethod("*");
    source.registerCorsConfiguration("/**", config);
    return new CorsFilter(source);
  }

do you have any idea how i can allow multiple origins. something like "host1","host2".. since the addAllowedOriginPattern() method accept only one string param.

Regards.

Solution

If you see the docs, the allowedOrigins is an array.

@Nullable
private List<String> allowedOrigins;

and the following method is setting the allowed Origins. Clearly, you can invoke the method multiple times to add the different origins.

    /**
     * Add an origin to allow.
     */
    public void addAllowedOrigin(String origin) {
        if (this.allowedOrigins == null) {
            this.allowedOrigins = new ArrayList<>(4);
        }
        else if (this.allowedOrigins == DEFAULT_PERMIT_ALL) {
            setAllowedOrigins(DEFAULT_PERMIT_ALL);
        }
        this.allowedOrigins.add(origin);
    }

OR

Use the following

public void setAllowedOrigins(@Nullable List<String> allowedOrigins) {
        this.allowedOrigins = (allowedOrigins != null ? new ArrayList<>(allowedOrigins) : null);
    }
