我有一個簡單的代理服務,它從csv文件讀取並使用smooks介體將其轉換爲XML消息。如果csv文件包含用單引號(')括起來的字段,那麼它效果很好。如何使用WSO2 ESB 4.8.1中的Smooks從csv文件中讀取使用雙引號括起來的字段

FileStructure:

'accountid','accountname','accountlocation' 
'121','dummyaccount','finland' 
'121','dummyaccount','finland' 
'121','dummyaccount','finland' 

但不幸的是在我的情況的字段被包圍在「雙引號」和Smooks的不解析文件,它是無法讀取該文件。

FileStructureDoubleQuotes:

"accountid","accountname","accountlocation" 
"121","dummyaccount","finland" 
"121","dummyaccount","finland" 
"121","dummyaccount","finland" 

代理服務:

<?xml version="1.0" encoding="UTF-8"?> 
<proxy xmlns="http://ws.apache.org/ns/synapse" 
     name="ConvertcsvfiletoXML" 
     transports="vfs"

    <parameter name="transport.vfs.ContentType">text/plain</parameter> 
    <parameter name="transport.vfs.ActionAfterFailure">MOVE</parameter> 
</proxy> 

的Smooks配置文件:

<smooks-resource-list xmlns="http://www.milyn.org/xsd/smooks-1.1.xsd" 
xmlns:csv="http://www.milyn.org/xsd/smooks/csv-1.1.xsd" 
xmlns:jms="http://www.milyn.org/xsd/smooks/jms-routing-1.2.xsd" 
xmlns:ftl="http://www.milyn.org/xsd/smooks/freemarker-1.1.xsd"> 

<params> 
<param name="stream.filter.type">SAX</param> 
<param name="stream.filter.readerPoolSize">300</param> 
</params> 

<csv:reader fields="id,name,location" separator="," quote="'" skipLines="1" /> 

<resource-config selector="csv-record"> 
<resource>org.milyn.delivery.DomModelCreator</resource> 
</resource-config> 

<ftl:freemarker applyOnElement="csv-record"> 
<ftl:template>/repository/resources/smooks/csv_record_as_xml.ftl</ftl:template> 
<ftl:use> 
<ftl:bindTo id="csv_record_as_xml"/> 
</ftl:use> 
</ftl:freemarker> 

<jms:router routeOnElement="csv-record" beanId="csv_record_as_xml" destination="TestQueue"> 
<jms:message> 
<!-- Need to use special FreeMarker variable ".vars" --> 
<jms:correlationIdPattern>${.vars["csv-record"].id}</jms:correlationIdPattern> 
</jms:message> 
<jms:jndi properties="/repository/resources/smooks/activemq.sr.jndi.properties" /> 
<jms:highWaterMark mark="10000000"/> 
</jms:router> 
</smooks-resource-list> 

對於下面的配置單引號的工作原理:

<csv:reader fields="id,name,location" separator="," quote="'" skipLines="1" /> 

但對於下面的配置不起作用雙引號:

<csv:reader fields="id,name,location" separator="," quote=" " " skipLines="1" /> 

那麼我們應該怎樣做在雙引號的情況下? 注意:將雙引號更改爲另一個特殊符號在我的情況下不是公開的。

「雙引號」爲默認值,因此,你只需要刪除屬性「報價」在節點「CSV:讀者」

另一個解決方法是使用一種特殊的漢字即可指定此值:

<csv:reader fields="id,name,location" separator="," quote="&#34;" skipLines="1"/>
