JNDI（Java Naming and Directory Interface）资源是Java EE中用于命名和目录服务的一种机制
BLOG域名:programb.blog.youkuaiyun.com
04-24 588
- Java 版本：JNDI 是 Java EE 规范，Java 8+ 完全兼容；Java 9+ 需添加 `javax.annotation-api` 依赖（因模块化移除了部分 EE 接口）。 - 容器版本：不同容器的 JNDI 配置方式差异较大（如 Tomcat vs JBoss），需根据容器类型调整配置。 - Spring 版本：Spring Framework 5.x+ 对 JNDI 的支持更稳定，建议使用 Spring 5.0+ 版本（Spring Boot 2.0+）。

这是由于重命名了项目名称引起的，在web.xml中又生成了xmlns="http://java.sun.com/xml/ns/javaee"，导致重复了。 解决办法：删除其中的一段后保存就可以了。
