Spring Boot Security And JSON Web Token 说明

流程说明

何时生成和使用jwt，其实我们主要是token更有意义并携带一些信息

https://github.com/Ants-double/huanhuncao/tree/master/visio

实操准备

新建一个spring boot 项目，并添加hello请求

工程目录结构如下

HelloWorldController 代码如下

package com.antsdouble.demojwt.controller;

import org.springframework.web.bind.annotation.GetMapping;

import org.springframework.web.bind.annotation.RestController;

@RestController

public class HelloWorldController {

    @GetMapping(value = {"/hello"})

    public String hello() {

        return "Hello World JWT";

    }

}

请求结果

配置Spring Security 和JWT

生成jwt

https://github.com/Ants-double/huanhuncao/tree/master/visio
```
如果请求authenticate 则会生成jwt
```
检证 jwt

https://github.com/Ants-double/huanhuncao/tree/master/visio

   1. 请求业务接口带上jwt 先验证通过后再处理具体的请求

配置数据库相关

application.yml

 jwt:

       secret: javainuse

     spring:

       datasource:

         url: jdbc:mysql://localhost:3306/test?useUnicode=true&characterEncoding=utf-8&useSSL=false&serverTimezone=CTT

         username: root

         password: 456123

         platform: mysql

       jpa:

         hibernate:

           ddl-auto: create-drop

添加对应的DTO 和DAO

package com.antsdouble.demojwt.model;

public class UserDTO {

    private String username;

    }

    public void setUsername(String username) {

        this.username = username;

    }

    public String getPassword() {

        return password;

    }

    public void setPassword(String password) {

        this.password = password;

    }

}
