Springboot 跨域配置无效及接口访问报错的解决方法

Springboot 跨域配置无效及接口访问报错的解决方法

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

4.0.0

org.springframework.boot

spring-boot-starter-parent

2.3.5.RELEASE

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 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);

}

}
