为什么Tomcat加载时Spring AOP XML schema没有正确加载'读取 beans.xml [英] Why isn't the Spring AOP XML schema properly loaded when Tomcat loads & reads beans.xml

问题描述

我正在尝试使用 Spring 的架构基于 Eclipse 中的 AOP 支持，尝试在 Tomcat 中加载配置时出现错误.

I'm trying to use Spring's Schema Based AOP Support in Eclipse and am getting errors when trying to load the configuration in Tomcat.

Eclipse 中没有错误并且自动完成功能对于 aop 命名空间正常工作，但是当我尝试将项目加载到 Eclipse 中时，我收到此错误:

There are no errors in Eclipse and auto-complete works correctly for the aop namespace, however when I try to load the project into eclipse I get this error:

09:17:59,515 WARN XmlBeanDefinitionReader:47 - 忽略 XML 验证警告org.xml.sax.SAXParseException: schema_reference.4: 无法读取架构文档http://www.springframework.org/schema/aop/spring-aop-2.5.xsd"，因为 1) 找不到文档；2) 无法读取文件；3) 文档的根元素不是 .

关注:

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，Tomcat解析beans.xml文件时似乎没有读取schema，导致无法识别元素.

Based on this, it seems the schema is not being read when Tomcat parses the beans.xml file, leading to the <aop:config> element not being recognised.

我的beans.xml文件如下:

My beans.xml file is as follows:

<?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 
            attribute -->

                    <bean class="org.apache.cxf.feature.LoggingFeature" />
            </jaxws:features>
    </jaxws:endpoint>


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

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


</beans>

我的 beans.xml 文件中的 元素是从 Spring 网站 尝试删除任何可能的错误来源

The <aop:config> element in my beans.xml file is copy-pasted from the Spring website to try and remove any possible source of error

任何人都可以解释为什么会发生此错误以及我可以做些什么来修复它?

推荐答案

检查您的 web 应用程序的 WEB-INF/lib 文件夹中是否有 Spring AOP jar (spring-aop.jar).

Check that you have the Spring AOP jar (spring-aop.jar) in the WEB-INF/lib folder of your webapp.

那个 jar 包含指定的 XSD.

That jar contais the specified XSD.
