1.4 数据库表设计
DROP TABLE IF EXISTS `sys_user`;
CREATE TABLE `sys_user` (
`id` bigint NOT NULL AUTO_INCREMENT COMMENT '主键',
`user_name` varchar(64) NOT NULL DEFAULT 'NULL' COMMENT '用户名',
`nick_name` varchar(64) NOT NULL DEFAULT 'NULL' COMMENT '昵称',
`password` varchar(64) NOT NULL DEFAULT 'NULL' COMMENT '密码',
`status` char(1) DEFAULT '0' COMMENT '账号状态(0正常 1停用)',
`email` varchar(64) DEFAULT NULL COMMENT '邮箱',
`phonenumber` varchar(32) DEFAULT NULL COMMENT '手机号',
`sex` char(1) DEFAULT NULL COMMENT '用户性别(0男,1女,2未知)',
`avatar` varchar(128) DEFAULT NULL COMMENT '头像',
`user_type` char(1) NOT NULL DEFAULT '1' COMMENT '用户类型(0管理员,1普通用户)',
`create_by` bigint DEFAULT NULL COMMENT '创建人的用户id',
`create_time` datetime DEFAULT NULL COMMENT '创建时间',
`update_by` bigint DEFAULT NULL COMMENT '更新人',
`update_time` datetime DEFAULT NULL COMMENT '更新时间',
`del_flag` int DEFAULT '0' COMMENT '删除标志(0代表未删除,1代表已删除)',
PRIMARY KEY (`id`)
) ENGINE=InnoDB AUTO_INCREMENT=2 DEFAULT CHARSET=utf8mb4 COLLATE=utf8mb4_0900_ai_ci COMMENT='用户表';
-- ----------------------------
-- Records of sys_user
-- ----------------------------
INSERT INTO `sys_user` VALUES ('1', 'liming', '黎明', '$2a$10$CLZ2BaVAaNnWJAi49MfdG.Tl9m4hKhMJOTNpPI34ftMnjQOLGl.M6', '0', '123@qq.com', '13012345678', '0', 'a', '1', '1', '2023-10-26 18:52:41', '1', '2023-10-26 18:52:49', '0');
二.数据库校验用户
自定义一个
UserDetailsService
的实现类,让SpringSecurity使用我们的实现类
。从数据库中查询用户名和密码。
@Service
public class UserDetailsServiceImpl implements UserDetailsService {
@Autowired
private UserMapper userMapper;
/**
* 按用户名加载用户
*
* @param username 用户名
* @return {@link UserDetails}
* @throws UsernameNotFoundException 用户名未发现异常
*/
@Override
public UserDetails loadUserByUsername(String username) throws UsernameNotFoundException {
// 1.根据用户名获取数据库中用户信息
LambdaQueryWrapper<User> lqw = new LambdaQueryWrapper<>();
lqw.eq(User::getUserName, username);
User user = userMapper.selectOne(lqw);
if (Objects.isNull(user)) {
throw new RuntimeException("用户名错误!");
}
// 2.@TODO 获取用户权限信息
// 3.返回UserDetails对象
return new LoginUser(user);
}
}
因为UserDetailsService
方法的返回值是UserDetails
类型,所以需要定义一个类,实现该接口,把用户信息封装在其中。
@Data
@NoArgsConstructor
@AllArgsConstructor
public class LoginUser implements UserDetails {
private User user;
/**
* 获取权限
*
* @return {@link Collection}<{@link ?} {@link extends} {@link GrantedAuthority}>
*/
@Override
public Collection<? extends GrantedAuthority> getAuthorities() {
return null;
}
/**
* 得到密码
*
* @return {@link String}
*/
@Override
public String getPassword() {
return user.getPassword();
}
/**
* 获得用户名
*
* @return {@link String}
*/
@Override
public String getUsername() {
return user.getUserName();
}
/**
* 账户未过期吗?
*
* @return boolean
*/
@Override
public boolean isAccountNonExpired() {
return true;
}
/**
* 账户未锁定吗?
*
* @return boolean
*/
@Override
public boolean isAccountNonLocked() {
return true;
}
/**
* 证书是否未过期?
*
* @return boolean
*/
@Override
public boolean isCredentialsNonExpired() {
return true;
}
/**
* 启用了
*
* @return boolean
*/
@Override
public boolean isEnabled() {
return true;
}
}
三.密码加密存储
实际项目中我们不会把密码明文存储在数据库中, 我们一般使用SpringSecurity为我们提供的
BCryptPasswordEncoder
,我们只需要使用把BCryptPasswordEncoder对象注入Spring容器中,SpringSecurity就会使用该PasswordEncoder来进行密码校验。 我们可以定义一个SpringSecurity的配置类。
@Configuration
public class SecurityConfig{
@Bean
public PasswordEncoder passwordEncoder(){
return new BCryptPasswordEncoder();
}
}
使用BCryptPasswordEncoder
的好处:
- BCryptPasswordEncoder可以实现自动帮我们密码加盐,这样虽然我们的密码是一样的,但是加盐后在数据库中存储的密文密码是不一样的
- BCryptPasswordEncoder加密网址:https://portal.he3app.com/home/extension/bcrypt-hash?posthog_from=Searchbar
四.自定义登陆接口
4.1 自定义一个controller登陆接口
@RestController
public class LoginController {
@Autowired
private LoginService loginService;
@PostMapping("/user/login")
public Result<Map<String, String>> login(@RequestBody User user) {
return loginService.login(user);
}
}
4.2 放行自定义登陆接口
@Configuration
public class SecurityConfig {
@Bean
public PasswordEncoder passwordEncoder() {
return new BCryptPasswordEncoder();
}
@Bean
public SecurityFilterChain filterChain(HttpSecurity http) throws Exception {
http
//关闭csrf
.csrf().disable()
//不通过Session获取SecurityContext
.sessionManagement().sessionCreationPolicy(SessionCreationPolicy.STATELESS)
.and()
.authorizeRequests()
// 对于登录接口 允许匿名访问
.antMatchers("/user/login").anonymous()
// 除上面外的所有请求全部需要鉴权认证
.anyRequest().authenticated();
return http.build();
}
// 注入AuthenticationConfiguration
@Autowired
private AuthenticationConfiguration authenticationConfiguration;
/**
* 通过authenticationConfiguration获取一个AuthenticationManager实例
* 这个Bean可以在其他地方被引用,以实现用户认证的功能
*
* @return {@link AuthenticationManager}
* @throws Exception 异常
*/
@Bean
public AuthenticationManager authenticationManager() throws Exception {
AuthenticationManager authenticationManager = authenticationConfiguration.getAuthenticationManager();
return authenticationManager;
}
}
4.3 使用AuthenticationManager auth方法进行验证
@Service
public class LoginServiceImpl implements LoginService {
@Autowired
private AuthenticationManager authenticationManager;
@Autowired
private RedisCache redisCache;
/**
* 登录
*
* @param user 用户
* @return {@link Result}
*/
@Override
public Result<Map<String, String>> login(User user) {
// 3.使用AuthenticationManager authenticate方法进行验证
UsernamePasswordAuthenticationToken usernamePasswordAuthenticationToken = new UsernamePasswordAuthenticationToken(user.getUserName(), user.getPassword());
Authentication authenticate = authenticationManager.authenticate(usernamePasswordAuthenticationToken);
//校验失败了
if (Objects.isNull(authenticate)) {
throw new AppException(AppExceptionCodeMsg.USERNAME_PASSWORD_ERR);
}
// 4.自己生成jwt给前端
LoginUser loginUser = (LoginUser) (authenticate.getPrincipal());
String userId = loginUser.getUser().getId().toString();
String jwt = JwtUtil.createJWT(userId);
Map<String, String> map = new HashMap<>();
map.put("token", jwt);
// 5.系统用户相关所有信息放入redis
redisCache.setCacheObject("login:" + userId, loginUser);
return Result.success("登陆成功", map);
}
}
五.认证过滤器
spring securirt自带16个过滤器链,我们前面自定义修改了
UsernamePasswordAuthenticationFilter
过滤器,但是后面的过滤器也需要使用Authentication
用户登录权限信息,所有我们就需要一个认证过滤器将用户的信息Authentication存入到SecurityContextHolder
供其他过滤器使用
实现步骤:
-
获取token
-
解析token
-
获取userid
-
封装Authentication
-
存入SecurityContextHolder
/**
* 描述:JWT身份验证令牌过滤器
* 创建人: 黎明
* 创建时间: 2023/10/27
* 版本: 1.0.0
* OncePerRequestFilter 只走一次,请求前
*/
@Component
public class JwtAuthenticationTokenFilter extends OncePerRequestFilter {
@Autowired
private RedisCache redisCache;
@Override
protected void doFilterInternal(HttpServletRequest request, HttpServletResponse response, FilterChain filterChain) throws ServletException, IOException {
// 1.获取token header的token
String token = request.getHeader("token");
if (!StringUtils.hasText(token)) {
//放行,让后面的过滤器执行报错
filterChain.doFilter(request, response);
return;
}
// 2.解析token
String userId;
try {
Claims claims = JwtUtil.parseJWT(token);
userId = claims.getSubject();
} catch (Exception e) {
throw new AppException(AppExceptionCodeMsg.TOKEN_ERR);
}
// 3.获取userId, redis获取用户信息
LoginUser loginUser = redisCache.getCacheObject("login:" + userId);
if (Objects.isNull(loginUser)) {
throw new AppException(AppExceptionCodeMsg.LOGIN_ERR);
}
// 4.封装Authentication
UsernamePasswordAuthenticationToken usernamePasswordAuthenticationToken
= new UsernamePasswordAuthenticationToken(loginUser, null, null);
// 5.存入SecurityContextHolder
SecurityContextHolder.getContext().setAuthentication(usernamePasswordAuthenticationToken);
//放行,让后面的过滤器执行
filterChain.doFilter(request, response);
}
}
过滤器配置(SecurityConfig文件中):
@Autowired
private JwtAuthenticationTokenFilter jwtAuthenticationTokenFilter;
//把token校验过滤器添加到过滤器链中(filterChain方法中)
http.addFilterBefore(jwtAuthenticationTokenFilter, UsernamePasswordAuthenticationFilter.class);
测试登录:
未登陆访问资源的话
携带token访问
六.退出登陆
写一个退出接口,删除reids里的key
即可
LoginController:
@PostMapping("/user/logout")
public Result logout(){
return loginService.logout();
}
LoginServiceImpl:
@Override
public Result logout() {
Authentication authentication = SecurityContextHolder.getContext().getAuthentication();
LoginUser loginUser = (LoginUser) authentication.getPrincipal();
Long userId = loginUser.getUser().getId();
redisCache.deleteObject("login:" + userId);
return Result.success("退出成功!");
}
测试:
登陆:
访问资源:
退出:
再访问资源:
