老表瞧一瞧，懒人工具类sign with apple 配置好需要的参数APPLICATION_ID 、SECRET_KEY 、FILE_KID 、TEAM_ID ，调getUserInfo()方法就完工了，不废话，看工具类

老表，光这么搞是不行滴，实体类也粘下：
package com.zjtx.dto;
public class AppleReturnTokenDTO {
private String access_token;
private String token_type;
private Integer expires_in;
private String refresh_token;
private String id_token;
public String getAccess_token() {
return access_token;
}
public void setAccess_token(String access_token) {
this.access_token = access_token;
}
public String getToken_type() {
return token_type;
}
public void setToken_type(String token_type) {
this.token_type = token_type;
}
public Integer getExpires_in() {
return expires_in;
}
public void setExpires_in(Integer expires_in) {
this.expires_in = expires_in;
}
public String getRefresh_token() {
return refresh_token;
}
public void setRefresh_token(String refresh_token) {
this.refresh_token = refresh_token;
}
public String getId_token() {
return id_token;
}
public void setId_token(String id_token) {
this.id_token = id_token;
}
}
最后就是maven依赖喽

注意点：io.jsonwebtoken.SignatureException: JWT signature does not * match locally computed signature. JWT validity cannot be asserted and should
这个异常是因为获取的公钥是一个数组，里面有多个，只取第一个的话会报这个异常，得根据identityToken里的kid去匹配到底取哪一个，要不然就会报签名不一致的问题，当然，我的工具类里已经处理了这个问题
