Spring|Spring Boot 整合 Sa-Token 实现登录认证 SpringBoot整合Sa-Token实现登录认

今天分享的是 Spring Boot 整合 Sa-Token 实现登录认证。
依赖首先，我们需要添加依赖：

关键依赖：

cn.dev33 sa-token-spring-boot-starter 1.28.0

其他依赖：

org.springframework.boot spring-boot-starter-web com.fengwenyi JavaLib 2.1.5 com.fengwenyi api-result 2.5.1 org.projectlombok lombok org.springframework.boot spring-boot-starter-validation

构造用户数据

public class UserData {private static final Map users = Map.of( "u1", new User("01", "u1", "123456", List.of("ROLE_USER")), "a2", new User("02", "a2", "123456", List.of("ROLE_ADMIN", "ROLE_USER")) ); public static class User { public String uid; public String username; public String password; public List roles; public User(String uid, String username, String password, List roles) { this.uid = uid; this.username = username; this.password = password; this.roles = roles; } }public static User queryByUsername(String username) { return users.get(username); }public static List queryRolesByUid(String uid) { for (Map.Entry entry : users.entrySet()) { if (uid.equals(entry.getValue().uid)) { return entry.getValue().roles; } } return null; }}

登录认证

@RestController @RequestMapping("/auth") public class AuthController {@PostMapping("/login") public ResponseTemplate login(@RequestBody @Validated LoginRequestVo requestVo) { String username = requestVo.getUsername(); String password = requestVo.getPassword(); UserData.User user = UserData.queryByUsername(username); if (Objects.isNull(user)) { return ResponseTemplate.fail("用户名不正确"); }if (!user.password.equals(password)) { return ResponseTemplate.fail("密码不正确"); }StpUtil.login(user.uid); LoginResponseVo responseVo = new LoginResponseVo() .setToken(StpUtil.getTokenValue()) ; return ResponseTemplate.success(responseVo); }}

关键代码

StpUtil.login(user.uid); LoginResponseVo responseVo = new LoginResponseVo() .setToken(StpUtil.getTokenValue()) ;

测试

【Spring|Spring Boot 整合 Sa-Token 实现登录认证】请求：

POST localhost:8080/auth/login{ "username": "u1", "password": "123456" }

响应：

{ "code": 0, "message": "Success", "success": true, "body": { "token": "f2f9a82f-bc6a-460a-877e-9d3e4c8867de" } }

退出登录

@RestController @RequestMapping("/auth") public class AuthController {@PostMapping("/logout") public ResponseTemplate logout() { StpUtil.logout(); return ResponseTemplate.success(); }}

前后端分离 header 添加
satoken = f2f9a82f-bc6a-460a-877e-9d3e4c8867de
到这里，登录就算完成了，希望今天的分享能够在工作中帮助到你。
