我正在尝试使用 Spring's Schema Based AOP Support在 Eclipse 中，尝试在 Tomcat 中加载配置时出现错误。

Eclipse 中没有错误，并且自动完成对于 aop 命名空间可以正常工作，但是当我尝试将项目加载到 eclipse 中时，出现此错误:

09:17:59,515 WARN XmlBeanDefinitionReader:47 - Ignored XML validation warning org.xml.sax.SAXParseException: schema_reference.4: Failed to read schema document 'http://www.springframework.org/schema/aop/spring-aop-2.5.xsd', because 1) could not find the document; 2) the document could not be read; 3) the root element of the document is not .

其次是:

SEVERE: StandardWrapper.Throwable org.springframework.beans.factory.xml.XmlBeanDefinitionStoreException: Line 39 in XML document from /WEB-INF/beans.xml is invalid; nested exception is org.xml.sax.SAXParseException: cvc-complex-type.2.4.c: The matching wildcard is strict, but no declaration can be found for element 'aop:config'.

Caused by: org.xml.sax.SAXParseException: cvc-complex-type.2.4.c: The matching wildcard is strict, but no declaration can be found for element 'aop:config'.

基于此，当 Tomcat 解析 beans.xml 文件时，似乎未读取架构，导致 <aop:config>元素未被识别。

我的beans.xml文件如下:

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

            id="iwebservices"
            implementor="ourdomain.iwebservices.IWebServiceImpl"
            endpointName="tns:IWebServiceImplPort"
            serviceName="tns:IWebService"
            address="/I"
            wsdlLocation="wsdl/I.wsdl">
            <!-- To have CXF auto-generate WSDL on the fly, comment out the above wsdl

            </jaxws:features>
    </jaxws:endpoint>


    <aop:config>
    <aop:aspect id="myAspect" ref="aBean">

    </aop:aspect>
    </aop:config>


</beans>

<aop:config>我的元素 beans.xml文件是从 Spring website 复制粘贴的尝试消除任何可能的错误来源

任何人都可以解释为什么会出现此错误以及我可以采取什么措施来解决它吗？

最佳答案

检查您的 webapp 的 WEB-INF/lib 文件夹中是否有 Spring AOP jar (spring-aop.jar)。

该 jar 包含指定的 XSD。

关于java - 为什么在 Tomcat 加载和读取 beans.xml 时没有正确加载 Spring AOP XML 模式，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/4437769/
