}
改成while在看看

你的加入驱动包了吗？

然后再把jsp页的代码贴上来看看。

看你的报错信息好象是在解析xml文件时出错,你仔细检查一下看看

这样，我刚少打了init

DataSource ds=(DataSource)initCtx.lookup("java:comp/env/jdbc/blog");

1.必须配在server.xml里。把配在别的地方的都删掉。

2。用这两行

Context initCtx = new InitialContext();
DataSource ds=(DataSource)ctx.lookup("java:comp/env/jdbc/blog");

替换这下面的三行
Context ctx = (Context) initCtx.lookup("java:comp/env");
//获取连接池对象
Object obj = (Object) ctx.lookup("jdbc/blog");
//类型转换
javax.sql.DataSource ds = (javax.sql.DataSource)obj;

记得要结贴给分。

1.在Index.jsp里，根本就没用到连接池，现在还是直连。

2.以下这段代码应该放在， server.xml里。

把上面的jsp的这句话
DataSource ds = (DataSource)initCtx.lookup("java:comp/env/jdbc/JavaSqlPool");
改为：
DataSource ds = (DataSource)initCtx.lookup("java:comp/env/jdbc/blog");

这个/env后面接的是jndi的名字。

你再试下

谢谢帮我看下哈！

在高并发场景下，传统PHP数据库连接方式容易导致连接数暴增，引发系统崩溃。PDO连接池通过复用连接，显著减少连接创建开销，避免超过MySQL的默认连接数限制，并提升连接稳定性。连接池的核心在于资源代理模式，通过初始化、获取、归还和健康检查等生命周期管理，确保连接的高效复用。文章详细介绍了如何用200行原生PHP代码实现连接池，并提供了核心参数调优指南。实战压测表明，使用连接池后，平均响应时间降低81%，QPS提升414%，CPU占用率减少51%。连接池技术不仅解决了高并发下的数据库连接问题，还大幅提升了系统

本文是一份MySQL数据库入门指南，用通俗语言解释核心概念，帮助初学者快速掌握数据库知识。数据库的必要性：对比文件存储的痛点（安全性差、查询困难、并发问题等），解释数据库的优势（安全控制、高效查询、事务保证等）。 MySQL架构：形象说明mysql（客户端）和mysqld（服务器端）的关系，类比银行系统（APP连接服务器）。数据库选择：比较主流数据库特点（MySQL适合互联网、Oracle适合企业、PostgreSQL全能、SQLite轻量）。

前面说了依赖怎么加，现在轮到最关键的一步：YAML配置。这一步要是没配好，后面再牛的功能也白搭。

本文深入探讨了FastAPI应用在高并发场景下的数据库连接池优化策略。通过详细解读SQLAlchemy连接池的核心参数配置，如pool_size、max_overflow、pool_recycle等，并结合实战代码示例，指导开发者如何避免连接池耗尽、管理数据库会话以及实施读写分离，从而有效提升应用性能和稳定性。
