WebConfig:
#Configuration
public class WebConfig extends WebMvcConfigurerAdapter {

public void addCorsMappings(CorsRegistry registry) {
registry.addMapping("/**")
.allowedMethods("HEAD", "GET", "PUT", "POST", "DELETE",

SwaggerConfig
#EnableSwagger2
#Configuration
public class SwaggerConfig {
#Bean

.apis(RequestHandlerSelectors.any())
.paths(PathSelectors.any())

Answer 1

Try this approach.
#Configuration
#ConfigurationProperties(prefix = "mycompany.cors")
public class CorsSettings {
final private Logger log = LoggerFactory.getLogger(CorsSettings.class);
private List<String> origins = new ArrayList<>();
public CorsSettings() {
log.debug("construct CorsSettings");
}
public List<String> getOrigins() {
return this.origins;
}
#Bean
public WebMvcConfigurer corsConfigurer() {
if (origins != null) {
log.debug("corsOrgins=" + origins);
} else {
log.error("corsOrgins=null");
}
return new WebMvcConfigurerAdapter() {
#Override
public void addCorsMappings(CorsRegistry registry) {
registry.addMapping("/**").allowedOrigins(origins.toArray(new String[origins.size()]));
}
};
}
}
Next in Config
#Configuration
public class SwaggerConfig {
ApiInfo apiInfo() {
return new ApiInfoBuilder().title("My Swagger API").description("This is a my swagger server")
.license("").licenseUrl("https://opensource.org/licenses/MIT").termsOfServiceUrl("").version("1.0.0")
.contact(new Contact("My name", "://www.mycompany.com", "myemail#mycompany.com"))
.build();
}
#Bean
public Docket customImplementation() {
return new Docket(DocumentationType.SWAGGER_2).select()
.apis(RequestHandlerSelectors.basePackage("com.mycompany.path")).build()
.apiInfo(apiInfo());
}
}
Then in application.yml
mycompany:
cors:
origins:
- ${origin1:http://localhost:8080}
- ${origin2:http://localhost:8080}
- ${origin3:http://localhost:8080}
- ${origin4:http://localhost:8080}
