前言

对接了自定义密码模式，但是返回的数据结构不符合要求

我们需要改成下面格式

开始

我假设你已经对接好了自定义密码功能，不会的话看下面文章

Spring Authorization Server 1.1 扩展实现 OAuth2 密码模式与 Spring Cloud 的整合实战（上）-阿里云开发者社区https://blog.51cto.com/u_15268610/6858078Spring Authorization Server 1.1 扩展实现 OAuth2 密码模式与 Spring Cloud 的整合实战（上）-阿里云开发者社区

重写✅ AuthenticationSuccessHandler 和❌ AuthenticationFailureHandler 的逻辑，就能够自定义认证成功和认证失败时的响应数据格式

config/AuthorizationServerConfig

.accessTokenResponseHandler(new MyAuthenticationSuccessHandler()) // 自定义成功响应
.errorResponseHandler(new MyAuthenticationFailureHandler()) // 自定义失败响应

 handler/MyAuthenticationSuccessHandler
