跨域配置如下，Springboot 版本为 2.4.1


///跨域访问配置
@Configuration
public class CorsConfig {
 private CorsConfiguration buildConfig() {
  CorsConfiguration corsConfiguration = new CorsConfiguration();
  corsConfiguration.setAllowCredentials(true); //sessionid 多次访问一致
  corsConfiguration.addAllowedOrigin("*"); // 允许任何域名使用
  corsConfiguration.addAllowedHeader("*"); // 允许任何头
  corsConfiguration.addAllowedMethod("*"); // 允许任何方法（post、get等）
  return corsConfiguration;
 }
 @Bean
 public CorsFilter corsFilter() {
  UrlBasedCorsConfigurationSource source = new UrlBasedCorsConfigurationSource();
  source.registerCorsConfiguration("/**", buildConfig()); // 对接口配置跨域设置
  return new CorsFilter(source);
 }
}

问题：跨域配置无效，访问接口报如下错误


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.

分析：

由于我是升级了 Springboot 到 2.4.1 版本之后才出现的这个问题，再结合报错信息提示不能使用*号设置允许的Origin，所以有两个解决方法。

解决方法：

1、降低 Springboot 版本


 <modelVersion>4.0.0</modelVersion>
 <parent>
  <groupId>org.springframework.boot</groupId>
  <artifactId>spring-boot-starter-parent</artifactId>
  <version>2.3.5.RELEASE</version>
  <relativePath/> <!-- lookup parent from repository -->
 </parent>

2、如果不降低版本，则在跨域设置时使用setAllowedOriginPatterns方法


///跨域访问配置
@Configuration
public class CorsConfig {
 private CorsConfiguration buildConfig() {
  CorsConfiguration corsConfiguration = new CorsConfiguration();
  corsConfiguration.setAllowCredentials(true); //sessionid 多次访问一致
  // 允许访问的客户端域名
  List<String> allowedOriginPatterns = new ArrayList<>();
  allowedOriginPatterns.add("*");
  corsConfiguration.setAllowedOriginPatterns(allowedOriginPatterns);
//  corsConfiguration.addAllowedOrigin("*"); // 允许任何域名使用
  corsConfiguration.addAllowedHeader("*"); // 允许任何头
  corsConfiguration.addAllowedMethod("*"); // 允许任何方法（post、get等）
  return corsConfiguration;
 }
 @Bean
 public CorsFilter corsFilter() {
  UrlBasedCorsConfigurationSource source = new UrlBasedCorsConfigurationSource();
  source.registerCorsConfiguration("/**", buildConfig()); // 对接口配置跨域设置
  return new CorsFilter(source);
 }
}
