Question

启动我的mule应用程序时遇到以下异常：

SEVERE: Line 6 in XML document from mule-spring-config.xml is invalid; nested exception is org.xml.sax.SAXParseException; lineNumber: 6; columnNumber: 41; cvc-elt.1: Cannot find the declaration of element 'beans'. (org.mule.api.lifecycle.InitialisationException)

以下XML是我的mule xml配置文件的开头。显然指定了spring bean的模式。更糟糕的是，完全相同的标题适用于另一个类似的应用程序。有没有人知道这里可能出现什么问题呢？

    <spring:property name="tokenProvider"
        ref="tokenProvider" />
    <spring:property name="credentialStoreClient" ref="credentialStoreClient" />
</spring:bean>

<flow name="API">
    <inbound-endpoint ref="REST" />
    <jersey:resources>
        <component class="com.api.system.VersionSender" />
        <component>
            <spring-object bean="authenticationProvider" />
        </component>
    </jersey:resources>
</flow>
</mule>

在我将VersionSender和身份验证提供程序类的包名从admin更改为system之前，这可能会有所帮助！

修改

Web.xml api-config.xml是上面的mule配置文件。

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE web-app PUBLIC "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN" "http://java.sun.com/dtd/web-app_2_3.dtd">
<web-app>

    <context-param>
        <param-name>org.mule.config</param-name>
        <param-value>api-config.xml</param-value>
    </context-param>

    <!-- To use a Mule XML configuration file use this context listener -->
    <listener>
        <listener-class>org.mule.config.builders.MuleXmlBuilderContextListener</listener-class>
    </listener>

</web-app>

检查嵌入在Web应用程序的WEB-INF/lib目录中的依赖项：对于Mule 3.3.0，Spring JAR的版本必须都是3.1.1.RELEASE。还要确保您实际上嵌入了Spring Beans JAR。
