篇首语:本文由小常识网(cha138.com)小编为大家整理,主要介绍了用户登录鉴权JWT代码实现相关的知识,希望对你有一定的参考价值。
实现流程
1、用户请求登录
2、Zuul将请求转发到授权中心,请求授权
3、授权中心校验完成,颁发JWT凭证
4、客户端请求其它功能,携带JWT
5、Zuul将jwt交给授权中心校验,通过后放行
6、用户请求到达微服务
7、微服务将jwt交给鉴权中心,鉴权同时解析用户信息
8、鉴权中心返回用户数据给微服务
9、微服务处理请求,返回响应
- jwt-parent:统一jar包版本控制
- jwt-pojo:实体类存放位置
- jwt-common:工具类、常量类等存放的位置
- jwt-auth:认证中心
- goods-search:商品搜索服务,对外暴露商品搜索相关接口
- user-service:用户服务,对外暴露用户操作相关接口,如新增用户等

这个标签一般用在父项目中,他不是导入jar包的标签,只是用来限定jar包版本的标签

启动Nacos注册中心
我这里启动是单节点模式
启动之后可以去页面访问Nacos,http://localhost:8845/nacos

创建实体类
Goods(我这里是商品和用户)
@Data
@AllArgsConstructor
@NoArgsConstructor
public class Goods
private Integer skuid;
private String goodsName;
private Double price;
User实体类
@Data
@AllArgsConstructor
@NoArgsConstructor
public class User
private Integer id;
private String username;
private String password;
搭建goods-search
功能分析
1、用户未登陆状态,可以搜索商品信息
2、goods-search为商品搜索服务,接收用户页面搜索请求
实现步骤:
1、pojo
2、controller
4、service
5、dao
