Question

我还是Mulesoft EE的新人。我需要从FTP服务器（Filezilla）获取CSV文件并将其插入MySQL数据库（Wamp）。

我想运行这个测试代码（我用HTTP替换了FTP以便测试）但是postman插件显示没有结果！

    <?xml version="1.0" encoding="UTF-8"?>

<mule xmlns:...>
    <db:mysql-config name="MySQL_Configuration" host="localhost"
        port="3306"   database="information"
        doc:name="MySQL Configuration" />
    <data-mapper:config name="CSV_To_XML" transformationGraphPath="csv_to_xml.grf" doc:name="CSV_To_XML"/>
    <jdbc-ee:mysql-data-source name="MySQL_Data_Source" user="User" password="Pass" url="jdbc:mysql://localhost:3306/information" transactionIsolation="UNSPECIFIED" doc:name="MySQL Data Source"/>

            <db:insert config-ref="MySQL_Configuration" doc:name="Database">

让我们看看以下内容是否对您有所帮助。只需将您的文件连接器替换为您的FTP连接器即可。

我使用Anypoint Studio 3.5 of MuleSoft中的DataMapper功能来实际地将CSV中的映射到我在流中使用的XML。在那里，您可以将csv的示例文件设置为输入示例，将xml设置为输出示例。

假设您提供的信息很少，我使用了以下文件......

用户csv作为DataMapper的输入格式示例：

date|serialnumber|gender|fullname|birthdate|email|mobilenumber|address
03-07-2014|129329|m|your name|12-03-1970|my@mail.com|219239|my address
04-07-2014|129329|w|her name|12-03-1975|her@mail.com|219229|her address

User XML I as DataMapper的输出格式示例注意：流变量和xpath表达式取决于它!!

<infos>
    <info>
        <date></date>
        <serialnumber></serialnumber>
        <gender></gender>
        <fullname></fullname>
        <birthdate></birthdate>
        <email></email>
        <mobilenumber></mobilenumber>
        <address></address>
    </info>
    <info>
        <date></date>
        <serialnumber></serialnumber>
        <gender></gender>
        <fullname></fullname>
        <birthdate></birthdate>
        <email></email>
        <mobilenumber></mobilenumber>
        <address></address>
    </info>
</infos>

祝你好运！

PS：不要忘记将mysql lib添加到类路径或maven。
