SpringBoot整合Sa

目录依赖登录退出登录前后端分离

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

登录

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;

pubhttp://lic 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

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();

}

}
