ossoprovider.endpoint.TokenEndpoint：处理错误：InvalidGrantException，错误的凭据

我正在开发Spring Cloud授权服务器 ，启动服务器时没有收到任何错误，但是当我尝试访问http：// localhost：9000 / services / oauth / token时 ，我收到以下错误。

你能指导一下这个问题吗？ 虽然grant_type是正确的，但我想知道为什么说无效补助金？

PluralsightSpringcloudM4SecureauthserverApplication

@SpringBootApplication @EnableAuthorizationServer @EnableResourceServer @RestController public class PluralsightSpringcloudM4SecureauthserverApplication { public static void main(String[] args) { SpringApplication.run(PluralsightSpringcloudM4SecureauthserverApplication.class, args); } @RequestMapping("/user") public Principal user(Principal user) { return user; } } 

ServiceConfig

 @Configuration public class ServiceConfig extends GlobalAuthenticationConfigurerAdapter { @Override public void init(AuthenticationManagerBuilder auth) throws Exception { auth.inMemoryAuthentication() .withUser("agoldberg").password("pass1").roles("USER").and() .withUser("bgoldberg").password("pass2").roles("USER", "OPERATOR"); } }
