今天内容主要是解决一位粉丝提的问题：如何在jwt中添加用户的额外信息并在资源服务器中获取这些数据。
涉及的知识点有以下三个：
*
如何在返回的jwt中添加自定义数据
*
如何在jwt中添加用户的额外数据，比如用户id、手机号码
*
如何在资源服务器中取出这些自定义数据
下面我们分别来看如何实现。
如何在返回的jwt中添加自定义数据
这个问题比较简单，只要按照如下两步即可：
*
编写自定义token增强器
package com.javadaily.auth.security;
import org.springframework.security.oauth2.common.DefaultOAuth2AccessToken;
import org.springframework.security.oauth2.common.OAuth2AccessToken;
import org.springframework.security.oauth2.provider.OAuth2Authentication;
import org.springframework.security.oauth2.provider.token.store.JwtAccessTokenConverter;
import java.util.HashMap; import java.util.Map; /** * <p>
* <code>JwtTokenEnhancer</code> * </p> * Description: * 自定义Token增强
