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

  1. jwt-parent：统一jar包版本控制
  2. jwt-pojo：实体类存放位置
  3. jwt-common：工具类、常量类等存放的位置
  4. jwt-auth：认证中心
  5. goods-search：商品搜索服务，对外暴露商品搜索相关接口
  6. user-service：用户服务，对外暴露用户操作相关接口，如新增用户等

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
