最近新写springboot，配置跨域配置文件后出现的问题。

org.springframework.web.util.NestedServletException: Request processing failed; nested exception is 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.

了解到在较新的springboot版本中，跨域配置需要将 .allowedOrigins 替换成 .allowedOriginPatterns

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

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