spring-boot - Springboot Oauth2：org.springframework.security.oauth2.provider.error.DefaultWebResponseExceptionTranslator$UnauthorizedException

Question

我正在尝试实现一个功能齐全的 Spring-boot oauth2。我设法使用成功凭据实现登录，我使用 access_token 和 refresh_token 得到正确的响应，使用/oauth/token

使用正确的用户名和密码

{
"access_token": "b8c45984-c573-4837-9ef6-6896f308a286",
"token_type": "bearer",
"refresh_token": "48145463-830e-4467-ab89-587bda6b32de",
"expires_in": 43199,
"scope": "read write"

}

如果我使用了错误的用户名，它会给我一个正确的错误，我很高兴；

错误的用户名：

{error: "unauthorized", error_description: "No value present"}

错误：“未经授权” error_description：“没有值存在”

但是当我使用正确的用户名和错误的密码时问题就来了；我收到以下错误
