🤞为什么这个东西我要分多篇写，我想说的是这个真不简单🤞
无论是shiro还是SpringSecurity，想要熟悉的使用，我们都要来回的摸索，各种认证和授权类，完全看的一塌糊涂，我不能说讲的很明白，只能说按教程一步步来能带你实现SpringSecurity集成JWT实现后端认证授权。
正菜来了🛴🛴🛴
🎈肯定先创建项目
直接springboot创建
springboot选用2.7.6版本
创建后打开
🎈再来创建各种文件夹和文件
之所以创建文件夹，下边要用到
🎈再来引入各种依赖
pom.xml
如果自己项目路径和我的不一样：只需要引入下边的properties 和dependencies
有mysql依赖，redis依赖，security依赖，swagger依赖，相对来说比较全了

🎈安装mysql和redis
-
安装Mysql(使用默认的3306端口)
在mysql中创建test数据库
设置账号：root 密码：password -
安装Redis 不用设置密码（生产环境需要设置密码，使用默认的6379端口）
🎈填写配置文件
application.yml
# 应用服务 WEB 访问端口
server:
port: 8080
spring:
datasource:
url: jdbc:mysql://localhost:3306/test?useUnicode=true&characterEncoding=utf8&serverTimezone=UTC # 数据库连接URL
username: root # 数据库用户名
password: password # 数据库密码
driver-class-name: com.mysql.cj.jdbc.Driver # MySQL驱动程序类名
type: com.alibaba.druid.pool.DruidDataSource # 指定使用Druid连接池
druid:
initial-size: 5 # 初始化时建立物理连接的个数
max-active: 20 # 最大连接池数量
min-idle: 5 # 最小连接池数量
max-wait: 60000 # 获取连接时最大等待时间，单位毫秒
validation-query: SELECT 1 FROM DUAL # 测试连接是否可用的SQL语句
test-while-idle: true # 保持连接池活跃地状态
time-between-eviction-runs-millis: 60000 # 检查空闲连接的时间间隔，单位毫秒
min-evictable-idle-time-millis: 300000 # 连接在连接池中最小空闲时间，单位毫秒
filters: stat,wall,log4j2 # 配置Druid监控和防御SQL注入的过滤器
data:
redis:
host: 127.0.0.1
port: 6379
database: 0
mvc:
pathmatch:
matching-strategy: ant_path_matcher
mybatis-plus:
mapper-locations: classpath:/mapper/*.xml # Mapper.xml文件所在路径
typeAliasesPackage: com.example.demo.domain # 实体类包名
configuration:
log-impl: org.apache.ibatis.logging.stdout.StdOutImpl # 日志输出方式
map-underscore-to-camel-case: true # 开启驼峰命名规则映射
🎈最后让项目跑起来
到这里项目就运行起来了
上图里运行程序之后有一个密码
Using generated security password: 248b72f4-198a-48ef-929e-1f3f2cd51c79
这个是springsecurity自带的密码，当我们访问接口的时候要用到的，默认用户名是user
🍚写个接口测试一下
在controller文件夹创建一个controller
package com.example.demo.controller;
import io.swagger.annotations.Api;
import io.swagger.annotations.ApiOperation;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.security.access.prepost.PreAuthorize;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;
@Api(tags = "测试类")
@RestController
@RequestMapping("/test")
public class TestController {
@ApiOperation(value = "测试方法")
@GetMapping("/test")
public String test(){
return "test";
}
}
重新运行程序
访问 http://localhost:8080/test/test
但是直接默认跳到了登录页
http://localhost:8080/login
输入用户名 user 和后台生成的密码
到此就创建好后端项目基本框架了。
🍚总结
大功告成，撒花致谢🎆🎇🌟，关注我不迷路，带你起飞带你富。
