Spring实战第6版第8章 OAuth2 客户端跑不起来

使用的SpringBoot 2.6.11，按照教程写的代码，就是跑不起来，一直报下面的错误：

no suitable httpmessageconverter found for response type [java.util.map<java.lang.string, java.lang.object>]

?后来看了配套资源的代码，在授权服务器的?AuthorizationServerConfig 中添加一个 Bean 解决了：

@Bean
public ProviderSettings providerSettings() {
    return ProviderSettings.builder().issuer("http://authserver:9000").build();
}

如果跑起来了，但是登陆后显示错误页面，可以参考这里的代码替换自动化配置：Completely Override the Auto-configuration

具体代码如下：
