Spring“元素”tx：annotation-driven“的前缀”tx“未绑定。”

Question

我在我的“tx：annotation-driven”这一行上得到了上面的错误，但是我已经在beans文件的顶部声明了命名空间，为什么下面的XML导致这个错误？

Answer 1

就像你其他的xmlns：definations，你需要一个的xmlns：TX

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

Answer 2

，你可以看看here进一步的信息：

的TX标签处理配置所有对Spring的 交易的全面支持。这些标签包含在名为第9章交易管理的 一章中。

...

在完整性的利益，要使用标签在TX模式，你 需要在Spring XML 配置文件的顶部以下的序言;以下代码段 中的底气文本引用了正确的模式，以便您可以使用tx命名空间中的标记 。

<?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:tx="http://www.springframework.org/schema/tx" 
     xsi:schemaLocation="

http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-2.0.xsd"> 

    <!-- <bean> definitions goes here --> 

</beans> 

Answer 3

你必须引入注释tx到您的项目，您必须安装它们，不要使用xmlns，它不让它正确工作，我发现你有注解的发展，其良好的实践经验，使用此，

http://www.springframework.org/schema/tx

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