春季 AOP 匹配的通配符很严格，但找不到元素'aop:config'的声明

Question

从类路径资源[ApplicationContextAOP.xml]的XML文档中的第13行无效;cvc-complex-type. 2.4.4 c:匹配的通配符是严格的，但是不能为元素'aop:config'找到声明。

    <!-- After bad performance(exception thrown) -->    
    <aop:after-throwing pointcut="execution(*com.idol.performers.Performer.perform(..))"
    method="demandRefund" />
</aop:aspect>
</aop:config>
<bean id="poeticDuke" class="com.idol.performers.PoeticJuggler">
<constructor-arg value = "15" />
<constructor-arg ref = "sonnet29" />
</bean>
</beans>

我看到了类似的错误，我很确定我的类路径是org.springframework.aop-3.1.0. m1 .jar

你能告诉我我错过了什么吗?

Answer 1

您需要添加到schemaLocation:

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

Answer 2

在之前提供的答案中添加另一种可能性:schemaLocation的错误版本:http://www.springframework.org/schema/aop /http://www.springframework.org/schema/aop/spring-aop-3.0.xsd正确的版本:http://www.springframework.org/schema/aophttp://www.springframework.org/schema/aop/spring-aop-3.0.xsd原因:"schema/aop"后面多了一个"/"

Answer 3

对于元素tx:advice，我们收到了类似的错误消息，并通过将org.springframework.*-3.0.0.M3.jar s替换为org.springframework.*-3.1.2.RELEASE.jar s来解决此问题，其中*表示jar模块。因此，尝试获得一个稳定的版本来修复类似的问题。

Answer 4

我在使用以下模式定义文件时遇到了这种情况。原因是额外的>在spring-aop-3.0.xsd之后。删除后解决。
