Spring「元素」tx：annotation-driven「的前綴」tx「未綁定。」

Question

我在我的「tx：annotation-driven」這一行上得到了上面的錯誤，但是我已經在beans文件的頂部聲明瞭命名空間，爲什麼下面的XML導致這個錯誤？

Answer 1

就像你其他的xmlns：definations，你需要一個的xmlns：TX

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

Answer 2

，你可以看看here進一步的信息：

的TX標籤處理配置所有對Spring的 交易的全面支持。這些標籤包含在名爲第9章交易管理的 一章中。

...

在完整性的利益，要使用標籤在TX模式，你 需要在Spring XML 配置文件的頂部以下的序言;以下代碼段 中的底氣文本引用了正確的模式，以便您可以使用tx命名空間中的標記 。

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

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

</beans> 

Answer 3

你必須引入註釋tx到您的項目，您必須安裝它們，不要使用xmlns，它不讓它正確工作，我發現你有註解的發展，其良好的實踐經驗，使用此，

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

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