在 tomcat 上部署 webapp 时面临的问题：Mule esb

Question

我尝试将我的 webapp 部署为 tomcat 服务。我关注这个链接https://github.com/ddossot/mule-in-action/tree/mule-3/chapter07/web-application 以下是我的 web.xml 文件

<?xml version="1.0" encoding="UTF-8"?>
<web-app version="2.5" xmlns="http://java.sun.com/xml/ns/javaee"

        <!-- Responses from the servlet are of type HTML by default -->
        <init-param>
            <param-name>org.mule.servlet.default.content.type</param-name>
            <param-value>text/html</param-value>

    </servlet>

    <servlet-mapping>

        <url-pattern>/services/*</url-pattern>
    </servlet-mapping>


    <welcome-file-list>
        <welcome-file>testindex.jsp</welcome-file>
    </welcome-file-list>
</web-app>

以下是我的 javatest.xml 文件

<data-mapper:config name="CSV_To_List_Transaction_c" transformationGraphPath="csv_to_list_transaction_c.grf" doc:name="CSV_To_List_Transaction"/>
    <sfdc:config name="Salesforce" username="username" password="pwd" doc:name="Salesforce" securityToken="token"/>

        <sfdc:create-bulk config-ref="Salesforce" type="Transaction__c" doc:name="Salesforce">

</flow>

当时我部署此应用时出现以下错误

WARN  2015-03-05 19:25:56,228 [main] org.eclipse.jetty: Error creating bean with name 'javatestFlow1': Cannot create inner bean '(inner bean)#e93ee6' of type [com.mulesoft.mule.module.datamapper.processors.DataMapperMessageProcessor] while setting bean property 'messageProcessors' with key [0]; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name '(inner bean)#e93ee6': Invocation of init method failed; nested exception is java.lang.RuntimeException: com.mulesoft.datamapper.exception.DataMapperRuntimeException: The data mapping graph csv_to_list_transaction_c.grf does not exists (org.mule.api.lifecycle.InitialisationException)

我想将此应用程序作为服务部署在 Tomcat 服务器上， 我该如何解决这个错误？请帮忙

谢谢

Answer 1

异常的重要部分是：

com.mulesoft.datamapper.exception.DataMapperRuntimeException
The data mapping graph csv_to_list_transaction_c.grf does not exists

要解决此问题，请确保在 WAR 文件中正确打包 csv_to_list_transaction_c.grf。它应该在类路径的根目录下，即WEB-INF/classes 的正下方。
