The prefix "tx" for element "tx:annotation-driven " is not bound

The prefix "tx" for element "tx:advice" is not bound

這個錯誤的原因很簡單是：

我們在定義申明AOP的時候。。沒有加載schema。

<beans>中要加入“xmlns：aop”的命名申明，並在“xsi：schemaLocation”中指定aop配置的schema的地址

 

配置文件如下：

<?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:aop="http://www.springframework.org/schema/aop "
xmlns:tx="http://www.springframework.org/schema/tx "
xsi:schemaLocation="http://www.springframework.org/schema/beans 
                     http://www.springframework.org/schema/beans/spring-beans.xsd 
                     http://www.springframework.org/schema/tx 
                     http://www.springframework.org/schema/tx/spring-tx.xsd 
                     http://www.springframework.org/schema/aop 
                     http://www.springframework.org/schema/aop/spring-aop.xsd ">
