cvc-complex-type.2.4.c：匹配的通配符是严格的，但是对于元素'cache：annotation-driven'没有声明。

Question

我目前正在尝试为我的应用程序实现缓存，并且我面临一个错误“cvc-complex-type.2.4.c：匹配通配符是严格的，但是对于元素'cache：annotation-driven'没有声明。”在我的pom.xml中。我在这里错过了什么吗？

的pom.xml

<?xml version="1.0" encoding="UTF-8"?>

<!-- Enables the caching through annotations -->

<!-- Generic cache manager based on the JDK ConcurrentMap -->

       p:name="task" /> 
     </set> 
    </property> 
</bean>

你在属性中的schemaLocation顺序是错误的。取而代之的

xsi:schemaLocation="http://www.springframework.org/schema/beans 
       http://www.springframework.org/schema/beans/spring-beans.xsd 
       http://www.springframework.org/schema/context 
       http://www.springframework.org/schema/context/spring-context.xsd 
       http://www.springframework.org/schema/tx 
       http://www.springframework.org/schema/cache 
       http://www.springframework.org/schema/cache/spring-cache.xsd 
       http://www.springframework.org/schema/tx/spring-tx.xsd" 

应该

xsi:schemaLocation="http://www.springframework.org/schema/beans 
       http://www.springframework.org/schema/beans/spring-beans.xsd 
       http://www.springframework.org/schema/context 
       http://www.springframework.org/schema/context/spring-context.xsd 
       http://www.springframework.org/schema/cache 
       http://www.springframework.org/schema/cache/spring-cache.xsd 
       http://www.springframework.org/schema/tx 
       http://www.springframework.org/schema/tx/spring-tx.xsd" 

中的schemaLocation值总是由元素对的。第一个元素表示在xmlns属性中使用的模式的标识符，每对中的第二个元素表示xsd文件的位置。在您的代码中，您基本上告诉解析器，标识符http://www.springframework.org/schema/tx的xsd文件位于http://www.springframework.org/schema/cache，标识符http://www.springframework.org/schema/cache/spring-cache.xsd的xsd文件位于http://www.springframework.org/schema/tx/spring-tx.xsd。
