java SecurityContextHolder提供了错误的用户详细信息

Question

在我的应用程序中，我们从SecurityContextHolder身份验证对象捕获每个事务的用户详细信息

但它似乎给出了错误的答案。下面是供您参考的代码片段

SecurityContext。xml

代码：

public static String getId() {
    Authentication auth = curityContextHolder.getContext().getAuthentication();

    if (auth != null) {
        Object principal = auth.getPrincipal();

        if (principal instanceof UserWithId) {
            return ((UserWithId) principal).getUserid();
        }
    }

    return null;
}

任何帮助都将不胜感激。提前谢谢

更新：

发生的情况是：

1. UserA登录并执行一些事务101:for transaction101:userIdfromSecurityContextHolder是UserA

2. 同时UserB登录到其他会话并执行一些事务103:for transaction103:userIdfromSecurityContextHolder是UserB

3. UserA再次执行一些事务106:for transaction106:userIdfromSecurityContextHolder是UserB而不是UserA
