無效的;嵌套例外是org.xml.sax.SAXParseException；期待命名空間“http://www.springframework.org/schema/data/jpa”，

我正在開發一個簡單的 Web 應用程式作為演示。我被這個錯誤困住了。Tomcat應用服務器在訪問應用背景關系url時報如下錯誤。我無法弄清楚這個錯誤的原因是什么。

mvn clean package 構建包很好

org.springframework.beans.factory.xml.XmlBeanDefinitionStoreException: Line 9 in XML document from ServletContext resource [/WEB-INF/dispatcherServlet-servlet.xml] is invalid; nested exception is org.xml.sax.SAXParseException; systemId: http://www.springframework.org/schema/tx/spring-tx-4.3.xsd; lineNumber: 9; columnNumber: 38; TargetNamespace.1: Expecting namespace 'http://www.springframework.org/schema/data/jpa', but the target namespace of the schema document is 'http://www.springframework.org/schema/tx'.

這是 dispatcherServlet-servlet.xml：

我正在運行 tomcat 版本 9.0.30 spring 版本 5.3.13 java 版本 11

可能是什么問題？

如果需要更多詳細資訊，請讓我。我將編輯并添加詳細資訊

uj5u.com熱心網友回復：

我猜問題是這一行：

http://www.springframework.org/schema/data/jpa http://www.springframework.org/schema/tx/spring-tx-4.3.xsd">

它應該是這樣的：

http://www.springframework.org/schema/data/jpa www.springframework.org/schema/data/jpa/spring-jpa-1.11.xsd">

我不是 Spring 專家，但我猜這是從命名空間到定義命名空間的檔案的映射
