1.第一种方式:编写配置类
import org.springframework.context.annotation.Bean; import org.springframework.context.annotation.Configuration; import org.springframework.web.cors.CorsConfiguration; import org.springframework.web.cors.UrlBasedCorsConfigurationSource; import org.springframework.web.filter.CorsFilter; @Configuration public class CorsConfig { private CorsConfiguration buildConfig() { CorsConfiguration corsConfiguration = new CorsConfiguration(); corsConfiguration.addAllowedOrigin("*"); //允许任何域名 corsConfiguration.addAllowedHeader("*"); //允许任何头 corsConfiguration.addAllowedMethod("*"); //允许任何方法 return corsConfiguration; } @Bean public CorsFilter corsFilter() { UrlBasedCorsConfigurationSource source = new UrlBasedCorsConfigurationSource(); source.registerCorsConfiguration("/**", buildConfig()); //注册 return new CorsFilter(source); } }
2.第二种方式:注解
@CrossOrigin(origins = "*", allowedHeaders = "*")
