Tomcat启动报错：“通配符的匹配很全面, 但无法找到元素 'tx:annotation-driven' 的声明“

从报错信息就可以明显察觉到是xml配置文件出现的问题

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xmlns:context="http://www.springframework.org/schema/context"
       xmlns:beans="http://www.springframework.org/schema/beans"

       xmlns:tx="http://www.springframework.org/schema/tx"

解决方案：这里是事物配置问题，确保上面配置的 xmlns和xsi 存在1对应2的关系即可。如

xmlns:tx="http://www.springframework.org/schema/tx"
对应

xsi:schemaLocation="http://www.springframework.org/schema/beans
下的

http://www.springframework.org/schema/tx
http://www.springframework.org/schema/tx/spring-tx-4.3.xsd
