如何在不使当前会话无效的情况下在JAVA中更改会话ID

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpSession;

public class SessionUtil {
    public static void changeSessionId(HttpServletRequest request) {
        HttpSession oldSession = request.getSession();
        oldSession.invalidate();
        
        HttpSession newSession = request.getSession(true);
        
        // 复制会话属性
        java.util.Enumeration<String> attributeNames = oldSession.getAttributeNames();
        while (attributeNames.hasMoreElements()) {
            String attributeName = attributeNames.nextElement();
            Object attributeValue = oldSession.getAttribute(attributeName);
            newSession.setAttribute(attributeName, attributeValue);
        }
        
        // 更新会话ID
        String newSessionId = newSession.getId();
        // 可以将新的会话ID存储到数据库或其他存储介质中
        
        // 打印新的会话ID
        System.out.println("New Session ID: " + newSessionId);
    }
}
