cvc-complex-type.2.4.c：匹配的通配符是嚴格的，但是對於元素'cache：annotation-driven'沒有聲明。

Question

我目前正在嘗試爲我的應用程序實現緩存，並且我面臨一個錯誤「cvc-complex-type.2.4.c：匹配通配符是嚴格的，但是對於元素'cache：annotation-driven'沒有聲明。」在我的pom.xml中。我在這裏錯過了什麼嗎？

的pom.xml

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

     </set> 
    </property>

你在屬性中的schemaLocation順序是錯誤的。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" 

應該

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值總是由元素對的。第一個元素表示在xmlns屬性中使用的模式的標識符，每對中的第二個元素表示xsd文件的位置。在您的代碼中，您基本上告訴解析器，標識符http://www.springframework.org/schema/tx的xsd文件位於http://www.springframework.org/schema/cache，標識符http://www.springframework.org/schema/cache/spring-cache.xsd的xsd文件位於http://www.springframework.org/schema/tx/spring-tx.xsd。
