WSO2 ESB - XML到MySQL数据库

Question

我需要一个解决问题的方法： 我刚试过了这个例子的WSO2 ESB和它的工作： http://wso2.org/library/articles/2011/01/wso2-esb-example-file-processing

但我喜欢用一个XML文件作为输入和把它写入MySQL-DB。 的XML文件看起来是这样的：

<?xml version="1.0" encoding="utf-8"?> 
<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/"> 
<soapenv:Body> 
    <Name>word</Name> 
    <Surname>processor</Surname> 
    <Phone>12333</Phone> 
</soapenv:Body> 
</soapenv:Envelope> 

如果我把这个变成我的“在” -folder文件将被移动到“出” -folder，但没有数据被写入到数据库中。没有错误消息。

我的代理服务：

<proxy xmlns="http://ws.apache.org/ns/synapse" name="FileProxy" transports="vfs" statistics="disable" trace="disable" startOnLoad="true"> 
    <target> 
     <inSequence> 
     <log level="full"/> 
     <clone> 
      <target sequence="fileWriteSequence"/> 
      <target sequence="databaseSequence"/> 
     </clone> 
     </inSequence> 
    </target> 
    <parameter name="transport.vfs.ActionAfterProcess">MOVE</parameter> 
    <parameter name="transport.PollInterval">15</parameter> 
    <parameter name="transport.vfs.MoveAfterProcess">C:/wso2esb/testordner/out</parameter> 
    <parameter name="transport.vfs.FileURI">C:/wso2esb/testordner/in</parameter> 
    <parameter name="transport.vfs.MoveAfterFailure">C:/wso2esb/testordner/error</parameter> 
    <parameter name="transport.vfs.FileNamePattern">.*.xml</parameter> 
    <parameter name="transport.vfs.ContentType">text/xml</parameter> 
    <parameter name="transport.vfs.ActionAfterFailure">MOVE</parameter> 
    <description></description> 
</proxy> 

我的顺序：

<?xml version="1.0" encoding="UTF-8"?> 
<sequence xmlns="http://ws.apache.org/ns/synapse" 
      name="databaseSequence" 
      trace="enable" 
      statistics="enable"> 
    <log level="full"> 
     <property name="sequence" value="before-smooks"/> 
    </log> 
    <smooks config-key="smooks"> 
     <input type="xml"/> 
     <output type="xml"/> 
    </smooks> 
    <log level="full"> 
     <property name="sequence" value="after-smooks"/> 
    </log> 
    <log level="full"> 
     <property xmlns:ns="http://org.apache.synapse/xsd" 
       name="name" 
       expression="//csv-record/name/text()"/> 
     <property xmlns:ns="http://org.apache.synapse/xsd" 
       name="surname" 
       expression="//csv-record/surname/text()"/> 
     <property name="phone" value="//csv-record/phone/text()"/> 
    </log> 
    <iterate xmlns:ns2="http://org.apache.synapse/xsd" 
      xmlns:ns="http://org.apache.synapse/xsd" 
      xmlns:sec="http://secservice.samples.esb.wso2.org" 
      expression="//csv-set/csv-record"> 
     <target> 
     <sequence> 
      <log level="full"> 
       <property name="State" value="Iteration"/> 
      </log> 
      <log level="full" category="DEBUG"/> 
      <dbreport> 
       <connection> 
        <pool> 
        <password>passwort</password> 
        <user>esb</user> 
        <url>jdbc:mysql://localhost:3306/</url> 
        <driver>com.mysql.jdbc.Driver</driver> 
        </pool> 
       </connection> 
       <statement> 
        <sql>insert into info.info (name, surname, phone) values (?, ?, ?)</sql> 
        <parameter expression="//csv-record/name/text()" type="VARCHAR"/> 
        <parameter expression="//csv-record/surname/text()" type="VARCHAR"/> 
        <parameter expression="//csv-record/phone/text()" type="VARCHAR"/> 
       </statement> 
      </dbreport> 
     </sequence> 
     </target> 
    </iterate> 
    <log level="full" category="DEBUG"/> 
</sequence> 

我认为这将是一个简单的问题，但我无法得到它... 像我说过，它使用普通的文本文件，但不使用XML。我试过不同的想法，不知道还有什么我可以尝试...... 有人知道我的错误是什么？

的fileWriteSequence看起来是这样的：

<?xml version="1.0" encoding="UTF-8"?> 
<sequence xmlns="http://ws.apache.org/ns/synapse" 
      name="fileWriteSequence" 
      trace="enable"

     <property name="sequence" value="fileWriteSequence"/> 
    </log>

      scope="transport"

    <send> 
     <endpoint name="FileEpr"> 
     <address uri="vfs:C:/wso2esb/testordner/out"/> 
     </endpoint> 
    </send> 
</sequence> 

的Smooks配置：

<smooks-resource-list xmlns="http://www.milyn.org/xsd/smooks-1.0.xsd"> 

    <!--Configure the CSVParser to parse the message into a stream of SAX events. --> 
    <resource-config selector="org.xml.sax.driver"> 
    <resource>org.milyn.csv.CSVParser</resource> 
    <param name="fields" type="string-list">name,surname,phone</param> 
    </resource-config> 

</smooks-resource-list> 

我也改了代码数据库序列如上。

谢谢。

Answer 1

您的代理服务看起来不错。但我没什么顾虑。

1. 你为什么要把sql查询作为CDATA。请参阅样本here。
2. 您还没有在连接url中提到数据库名称。可能它不是一个问题，因为你已经在sql查询中使用了database.table格式。
3. 修复之后，如果问题仍然存在，请使用1和2，然后尝试仅使用一个序列的代理。即暂时避免文件写入序列，并仅使用dbwrite序列进行尝试。

您还可以记录您要在DBReport介体之前插入的条目。即在smooks中介之后，放置一个日志中介并记录名字，姓氏和电话。这将确保您试图插入从消息中正确提取的值。
