在访问web工程的时候，经常会报一些跨域的错误：CORS header ‘Access-Control-Allow-Origin’ missing


spring boot中的cors设定方式

@ConfigurationpublicclassWebConfigextendsWebMvcConfigurerAdapter{@OverridepublicvoidaddCorsMappings(CorsRegistryregistry){registry.addMapping("/**").allowedOrigins("*").allowCredentials(true).allowedMethods("GET","POST","DELETE","PUT").maxAge(3600);}}
