下面是Spring Security踢出在线用户的代码实现,仅供参考:
1. 实现SessionRegistry接口
```
@Component
public class CustomSessionRegistry implements SessionRegistry {
private final Map<String, SessionInformation> sessionsById = new ConcurrentHashMap<>();
private final Map<Object, String> principalSessionIds = new ConcurrentHashMap<>();
@Override
public List<Object> getAllPrincipals() {
return new ArrayList<>(principalSessionIds.keySet());
}
@Override
public List<SessionInformation> getAllSessions(Object principal, boolean includeExpiredSessions) {
String sessionId = principalSessionIds.get(principal);
if (sessionId != null) {
SessionInformation sessionInformation = sessionsById.get(sessionId);
if (sessionInformation != null) {
return Arrays.asList(sessionInformation);
}
}
return Collections.emptyList();
}
@Override
public SessionInformation getSessionInformation(String sessionId) {
return sessionsById.get(sessionId);
}
@Override
public void refreshLastRequest(String sessionId) {
SessionInformation sessionInformation = sessionsById.get(sessionId);
if (sessionInformation != null) {
sessionInformation.refreshLastRequest();
}
}
@Override
public void registerNewSession(String sessionId, Object principal) {
Assert.notNull(sessionId, "Session ID cannot be null");
Assert.notNull(principal, "Principal cannot be null");
if (sessionsById.containsKey(sessionId)) {
removeSessionInformation(sessionId);
}
SessionInformation sessionInformation = new SessionInformation(principal, sessionId, new Date());
sessionsById.put(sessionId, sessionInformation);
principalSessionIds.put(principal, sessionId);
}
@Override
public void removeSessionInformation(String sessionId) {
SessionInformation sessionInformation = sessionsById.get(sessionId);
if (sessionInformation != null) {
principalSessionIds.remove(sessionInformation.getPrincipal());
sessionsById.remove(sessionId);
}
}
}
```
2. 配置HttpSessionEventPublisher
在Spring Security配置类中添加以下代码:
```
@Bean
public static HttpSessionEventPublisher httpSessionEventPublisher() {
return new HttpSessionEventPublisher();
}
```
3. 配置会话管理策略
在Spring Security配置类中添加以下代码:
```
@Override
protected void configure(HttpSecurity http) throws Exception {
http
// ...
.sessionManagement()
.maximumSessions(1) // 最大会话数
.expiredSessionStrategy(expiredSessionStrategy()) // 会话过期策略
.sessionRegistry(sessionRegistry()); // 注册SessionRegistry
}
@Bean
public SessionRegistry sessionRegistry() {
return new CustomSessionRegistry();
}
@Bean
public SessionInformationExpiredStrategy expiredSessionStrategy() {
return new CustomExpiredSessionStrategy();
}
```
4. 自定义LogoutSuccessHandler
```
@Component
public class CustomLogoutSuccessHandler extends SimpleUrlLogoutSuccessHandler {
private final SessionRegistry sessionRegistry;
public CustomLogoutSuccessHandler(SessionRegistry sessionRegistry) {
this.sessionRegistry = sessionRegistry;
}
@Override
public void onLogoutSuccess(HttpServletRequest request, HttpServletResponse response, Authentication authentication) throws IOException, ServletException {
super.onLogoutSuccess(request, response, authentication);
if (authentication != null && authentication.getPrincipal() != null) {
sessionRegistry.removeSessionInformation(request.getSession().getId());
}
}
}
```
5. 强制用户下线
在需要强制用户下线的地方调用以下代码:
```
@Autowired
private SessionRegistry sessionRegistry;
public void forceLogout(Object principal) {
List<SessionInformation> sessions = sessionRegistry.getAllSessions(principal, false);
for (SessionInformation session : sessions) {
session.expireNow(); // 将会话立即过期,即强制下线
}
}
```
