一个运行了很久的项目（暂时无人使用）需要迁移，自己也搞不清什么时候开始页面跨域报错：

Access to XMLHttpRequest at 'http://127.0.0.1:8080/xxx' from origin 'http://127.0.0.1:8081' has been blocked by CORS policy: No 'Access-Control-Allow-Origin' header is present on the requested resource.

搜索报错信息，尝试了网上多种解决方案未果，因为项目长时间除了偶尔打安全补丁完全没有改动，所以一开始没有想到后端针对跨域有报错信息：

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.

针对后端报错再进行搜索，找到了问题所在，参见：
