Spring Security Oauth2.0获取token报错如下：

{
"error": "invalid_client",
"error_description": "Bad client credentials"
}

百度google了很多，基本上都解决不了我的问题。最后在一篇国外的文章的评论里找到了解决方法，特此记录。

将ClientDetailsServiceConfigurer的configure里的.secret("secret")改为.secret(passwordEncoder().encode("secret"))即可。

其中的passwordEncoder函数为

public BCryptPasswordEncoder passwordEncoder(){
    return new BCryptPasswordEncoder();
}
