SpringBoot 配置跨域时出现如下异常:
java.lang.IllegalArgumentException: When allowCredentials is true, allowedOrigins cannot contain the special value "*" since that cannot be set on the "Access-Control-Allow-Origin" response header. To allow credentials to a set of origins, list them explicitly or consider using "allowedOriginPatterns" instead.
SpringBoot升级2.4.0+之后,跨域配置中的.allowedOrigins
不再可用
将配置中的.allowedOrigins
替换成.allowedOriginPatterns
即可。
SpringBoot 2.0.0<=version<2.4.0
@Configuration public class CorsConfig implements WebMvcConfigurer { @Override public void addCorsMappings(CorsRegistry registry) { registry.addMapping("/**") .allowedOrigins("*") .allowedMethods("GET", "HEAD", "POST", "PUT", "DELETE", "OPTIONS") .allowCredentials(true) .maxAge(3600) .allowedHeaders("*"); } }
SpringBoot >= 2.4.0
@Configuration public class CorsConfig implements WebMvcConfigurer { @Override public void addCorsMappings(CorsRegistry registry) { registry.addMapping("/**") .allowedOriginPatterns("*") .allowedMethods("GET", "HEAD", "POST", "PUT", "DELETE", "OPTIONS") .allowCredentials(true) .maxAge(3600) .allowedHeaders("*"); } }
