#jsp页面seesion值取不到

在JSP应用中遇到一个问题，即在后台设置的Session值在前端页面无法获取。怀疑可能是配置文件的问题。尝试检查并调试相关过滤器，如SessionMonitorFilter和SessionCheckFilter，以确定问题所在。

jsp页面seesion值取不到
jsp上画面取不到session的值。会不会是配置文件问题~
后台设值了，前台就是取不到啊~
有没有人遇到过这个问题的，求指导

JSPsession获取不到值
最新发布
10-07
JSP (JavaServer Pages) 中，`session` 对象通常用于存储用户会话信息。如果你遇到无法从 `session` 获取到预期值的情况，可能是以下几个原因： 1. **未设置 session**：确保你在创建或设置值之前已经通过 `request.getSession()` 创建了 session 对象，并使用 `setAttribute()` 方法添加数据。 ```java Session session = request.getSession(); session.setAttribute("key", "value"); ``` 2. **跨域问题**：如果从非同源的页面尝试访问 session，浏览器出于安全原因可能会阻止。检查你的前端请求是否允许跨域。 3. **会话过期**：如果用户长时间未活动，浏览器或服务器可能会自动清除 session。你需要确保在适当的时间更新或刷新 session。 4. **代码执行时间问题**：检查你的代码是否在正确的生命周期阶段获取 session，比如放在 `doGet()` 或 `doPost()` 方法内，而不是在整个页面加载时。 5. **复用问题**：如果在请求处理期间多次初始化了 session，可能导致 session 对象被覆盖，检查代码中是否有意外的新 session 初始化。 6. **编码错误**：检查键名拼写是否一致，以及 session 中的数据类型和获取代码是否匹配。 若以上都排除了，还存在问题，你可以通过打印日志或使用 `session.getAttribute()` 的返回值来进一步调试： ```java Object value = session.getAttribute("key"); if (value == null) { System.out.println("Session attribute not found."); } ```
