spring security corsfilter 跨域 springsecurity跨域配置

spring security 自定义登录以及配置跨域问题

• springboot低版本升级高版本跨域配置稍微有些不一样，见下面代码的corsConfigurationSource()方法。
• 此处登录即支持客户端传json格式参数，也支持springSecurity默认支持的formData格式的参数（username和password）

        corsConfiguration.addAllowedHeader("*");//header，允许哪些header，本案中使用的是token，此处可将*替换为token；
        corsConfiguration.addAllowedMethod("*");	//允许的请求方法，PSOT、GET等
