匹配的通配符是嚴格的，但是對於元素'tx：annotation-driven''context：component-scan'沒有發現聲明

Question

任何人都可以識別下面的命名空間聲明有什麼問題嗎？我已經提到了所有的命名空間，並提供了對模式文件的引用。不知道還有什麼缺失。

<?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" 
    xmlns:context="http://www.springframework.org/schema/context" 
    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  
      http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd"> 

    <context:component-scan base-package="com.mypackage" /> 
    <context:annotation-config /> 
    <tx:annotation-driven /> 

</beans> 

錯誤消息： - CVC-復type.2.4.c：

在此行中發現

多個註解的匹配通配符是嚴格的，但沒有聲明可以找到元素' TX：註解驅動的」。 - schema_reference.4：無法讀取模式文檔'http://www.springframework.org/schema/tx/spring-tx.xsd'，因爲1） 找不到文檔; 2）文件無法閱讀; 3） 該文件的根元素不是<xsd:schema>。

我更喜歡在STS Eclipse和這是一個如何重現該問題...

我有一個Spring上下文相關性的Maven項目：

的pom.xml

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
    xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd"> 
    <modelVersion>4.0.0</modelVersion> 
    <groupId>betlista</groupId> 
    <artifactId>tests.so.q34779551</artifactId> 
    <version>0.0.1-SNAPSHOT</version> 
    <name>SO-q34779551</name> 

    <dependencies> 
     <dependency> 
      <groupId>org.springframework</groupId> 
      <artifactId>spring-core</artifactId> 
      <version>4.2.4.RELEASE</version> 
     </dependency> 
    </dependencies> 

</project> 

當我現在創建spring.xml在src/main/resources相同作爲你我有同樣的問題：

schema_reference.4: Failed to read schema document 'http://www.springframework.org/schema/beans/spring-beans.xsd', because 1) could not find the document; 2) the document could not be read; 3) the root element of the document is not <xsd:schema>. 
schema_reference.4: Failed to read schema document 'http://www.springframework.org/schema/context/spring-context.xsd', because 1) could not find the document; 2) the document could not be read; 3) the root element of the document is not <xsd:schema>. 
schema_reference.4: Failed to read schema document 'http://www.springframework.org/schema/context/spring-context.xsd', because 1) could not find the document; 2) the document could not be read; 3) the root element of the document is not <xsd:schema>. 
schema_reference.4: Failed to read schema document 'http://www.springframework.org/schema/tx/spring-tx.xsd', because 1) could not find the document; 2) the document could not be read; 3) the root element of the document is not <xsd:schema>. 

問題是，spring-tx和spring-context不在依賴關係中 - 添加時，錯誤是固定的。
