Java cvc complex type.2.4.c：匹配的通配符是严格的，但是找不到元素'；缓存：注释驱动'；

我目前正在尝试为我的应用程序实现缓存，但我在pom.xml中遇到了一个错误“cvc complex type.2.4.c:匹配的通配符是严格的，但是找不到元素“cache:annotation-driven.”的声明。我有什么遗漏吗

pom.xml

您在属性schemaLocation中的顺序是错误的。而不是

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"

应该是

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"

schemaLocation中的值总是由成对的元素组成。第一个元素表示在xmlns属性中使用的模式标识符，每对中的第二个元素表示xsd文件的位置。在代码中，您基本上告诉解析器，标识符的xsd文件

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

位于

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

和标识符的xsd文件

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

位于

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