    这是一个创建于 1729 天前的主题,其中的信息可能已经有所发展或是发生改变。
    改造个老项目,配置 xml 老报这个错:

    org.springframework.beans.factory.BeanDefinitionStoreException: Unexpected exception parsing XML document from class path resource [dubbo.xml]; nested exception is org.springframework.beans.FatalBeanException: Invalid NamespaceHandler class [org.apache.dubbo.config.spring.schema.DubboNamespaceHandler] for namespace [http://dubbo.apache.org/schema/dubbo]: problem with handler class file or dependent class; nested exception is java.lang.VerifyError: class org.apache.dubbo.config.spring.schema.DubboNamespaceHandler overrides final method parse.(Lorg/w3c/dom/Element;Lorg/springframework/beans/factory/xml/ParserContext;)Lorg/springframework/beans/factory/config/BeanDefinition;

    有不有老哥遇到这个问题啊?

    我的 dubbo.xml 配置:

    <beans xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xmlns:dubbo="http://dubbo.apache.org/schema/dubbo"
    xmlns="http://www.springframework.org/schema/beans"
    xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd
    http://dubbo.apache.org/schema/dubbo http://dubbo.apache.org/schema/dubbo/dubbo.xsd">

    <dubbo:application name="test"/>
    <dubbo:registry group="${dubbo_reference_group}" address="${dubbo_registry_address}"/>
    <dubbo:reference id="servicexxx" check="false" interface="com.t.defaukt.Servicexxx" version="1.0.0"/>
    </beans>

    @lxk11153 还是这个提示,NamespaceHandler 这个好像是解析自定义标签,看样子是标签解析不成功

    由 dubbo-*.*.*.jar 下 /META-INF/spring.schemas 可知 (/META-INF/spring.handlers)
    http\://dubbo.apache.org/schema/dubbo/dubbo.xsd=META-INF/dubbo.xsd
    http\://code.alibabatech.com/schema/dubbo/dubbo.xsd=META-INF/compat/dubbo.xsd
    配置 dubbo.apache.orgcode.alibabatech.com (for compat)是一样的

    @lxk11153 看了下报错在 package org.springframework.beans.factory.xml ,catch 了 LinkageError 可能是兼容的问题,我在研究下
    public NamespaceHandler resolve(String namespaceUri) {
    Map handlerMappings = this.getHandlerMappings();
    Object handlerOrClassName = handlerMappings.get(namespaceUri);
    if (handlerOrClassName == null) {
    return null;
    } else if (handlerOrClassName instanceof NamespaceHandler) {
    return (NamespaceHandler)handlerOrClassName;
    } else {
    String className = (String)handlerOrClassName;

    try {
    Class handlerClass = ClassUtils.forName(className, this.classLoader);
    if (!NamespaceHandler.class.isAssignableFrom(handlerClass)) {
    throw new FatalBeanException("Class [" + className + "] for namespace [" + namespaceUri + "] does not implement the [" + NamespaceHandler.class.getName() + "] interface");
    } else {
    NamespaceHandler namespaceHandler = (NamespaceHandler)BeanUtils.instantiateClass(handlerClass);
    namespaceHandler.init();
    handlerMappings.put(namespaceUri, namespaceHandler);
    return namespaceHandler;
    }
    } catch (ClassNotFoundException var7) {
    throw new FatalBeanException("NamespaceHandler class [" + className + "] for namespace [" + namespaceUri + "] not found", var7);
    } catch (LinkageError var8) {
    throw new FatalBeanException("Invalid NamespaceHandler class [" + className + "] for namespace [" + namespaceUri + "]: problem with handler class file or dependent class", var8);
    }
    }
    }

    Java 8 and Spring 2.5 好像是不兼容的,网上一搜就有

    比如覆盖 org.springframework.core.JdkVersion 可以解决
