java - Spring AOP : "no declaration can be found for element ' aop:config' "

Question

我已经看到这个问题的一些实例已经提出。但是，我有信心满足这些解决方案中列出的标准。即我很确定我的类路径上有所需的 jar + 我的模式位置地址按顺序排列。

一个解决方案提到该问题可能是由于在类路径上有另一个 XML 解析器。我的类路径中确实有 dom4j，但我已将其删除以进行测试，但问题仍然存在。

这是我的类路径:

这是我的 xml:

<?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"
    xsi:schemaLocation="

        http://www.springframework.org/schema/aop
        http://www.springframework.org/schema/aop/spring-aop-3.0.xsd
        http://www.springframework.org/schema/context/spring-context-3.0.xsd">

    <bean id="timer" class="ie.ucd.dec.al.rugby.aop.Timer" />

    <aop:config>
        <aop:aspect ref="timer">
            <aop:pointcut id="migrationManager_migrate"
                expression="execution(* ie.ucd.dec.al.rugby.data.migrate.MigrationManager.migrateAllXmlFilesInDirectory())" />

            <aop:around pointcut-ref="migrationManager_migrate"
                method="timeJob()" />
        </aop:aspect>

    </aop:config>

</beans>

最后，这是我的堆栈跟踪:

希望有人能提供帮助。

谢谢!

xsi:schemaLocation 项的顺序错误，每个命名空间 URI 后面应该跟它的 XSD 位置:

xsi:schemaLocation="
     http://www.springframework.org/schema/beans             
     http://www.springframework.org/schema/beans/spring-beans-3.0.xsd         
     http://www.springframework.org/schema/context
