本文主要是介绍[转]When allowCredentials is true, allowedOrigins cannot contain the special value “*“，对大家解决编程问题具有一定的参考价值，需要的程序猿们随着小编来一起学习吧！

前言

　　项目接口访问出现allowedOrigins cannot contain the special value "*"

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.

修改方式

修改allowedOrigins为allowedOriginPatterns

（1）修改前：

@Override
public void addCorsMappings(CorsRegistry registry) {
    registry.addMapping("/**")
            .allowedOrigins("*")
            .allowedMethods("GET", "HEAD", "POST", "PUT", "DELETE", "OPTIONS")
            .allowCredentials(true)
            .maxAge(3600)
            .allowedHeaders("*");
}

（2）修改后：

@Override
public void addCorsMappings(CorsRegistry registry) {
    registry.addMapping("/**")
            .allowedOriginPatterns("*")
            .allowedMethods("GET", "HEAD", "POST", "PUT", "DELETE", "OPTIONS")
            .allowCredentials(true)
            .maxAge(3600)
            .allowedHeaders("*");
}
