春季启动：error =“ invalid_grant”，error_description =“错误的凭据”

Question

我写了一个非常简单的Spring Boot应用程序。

为了获得身份验证令牌，我使用了以下curl命令。但是相反，我在服务器日志（Eclipse控制台）中看到以下错误：error="invalid_grant", error_description="Bad credentials"

curl -v -u greetings:123456 -X POST http://localhost:8080/oauth/token -H "Accept: application/json" -d "username=username&password=password&grant_type=password&scope=write&client_secret=12345&client_id=greetings"

我想知道：

我做错了什么不让我得到auth code？

添加@Configuration到WebSecurityConfiguration类。这样您的bean将在春季上下文中注入。

ps您在此处尝试执行的操作OAuth2 password grant不会返回auth代码，而是直接向您返回一个accessToken。
