明天分享的是 Spring Boot 整合 Sa-Token 实现登录认证。

依赖

首先，咱们须要增加依赖：

  • 要害依赖：
<dependency>    <groupId>cn.dev33</groupId>    <artifactId>sa-token-spring-boot-starter</artifactId>    <version>1.28.0</version></dependency>
  • 其余依赖：
<dependencies>    <dependency>        <groupId>org.springframework.boot</groupId>        <artifactId>spring-boot-starter-web</artifactId>    </dependency>        <dependency>        <groupId>com.fengwenyi</groupId>        <artifactId>JavaLib</artifactId>        <version>2.1.5</version>    </dependency>    <dependency>        <groupId>com.fengwenyi</groupId>        <artifactId>api-result</artifactId>        <version>2.5.1</version>    </dependency>    <dependency>        <groupId>org.projectlombok</groupId>        <artifactId>lombok</artifactId>    </dependency>    <dependency>        <groupId>org.springframework.boot</groupId>        <artifactId>spring-boot-starter-validation</artifactId>    </dependency></dependencies>

登录

  • 结构用户数据
public class UserData {    private static final Map<String, User> 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<String> roles;        public User(String uid, String username, String password, List<String> 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<String> queryRolesByUid(String uid) {        for (Map.Entry<String, User> 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<LoginResponseVo> 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("明码不正确");        }        StpUtil.login(user.uid);        LoginResponseVo responseVo = new LoginResponseVo()                .setToken(StpUtil.getTokenValue())                ;        return ResponseTemplate.success(responseVo);    }}

要害代码

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

申请：

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<Void> logout() {        StpUtil.logout();        return ResponseTemplate.success();    }}

前后端拆散

header 增加

satoken = f2f9a82f-bc6a-460a-877e-9d3e4c8867de

到这里，登录就算实现了，心愿明天的分享可能在工作中帮忙到你。
