（9）WSO2 ESB功能——数据转换

标签：wso2

这篇文章介绍如何通过WSO2 ESB实现数据转换的功能：如改变消息值，“0”转换为“律师投诉”，“1”转换为“公证员投诉”；改变消息标签，添加消息属性等。

场景一：投诉管理
描述：改变消息值，“0”转换为“L”，“1”转换为“N”
1 创建法律援助服务

参见代码FayuanService，打包为FayuanService_1.0.0.aar服务发布。

2、创建代理服务

<?xml version="1.0" encoding="UTF-8"?>
<proxy xmlns="http://ws.apache.org/ns/synapse"
       name="FayuanProxy"
       transports="https,http"
       statistics="enable"
       trace="enable"
       startOnLoad="true">
   <target>
      <inSequence>
         <send>
            <endpoint key="FayuanEndpoint"/>
         </send>
      </inSequence>
      <outSequence>
         <log level="full">
            <property name="before" value="beforeTransform"/>
         </log>
         <xslt key="fyResponse.xslt"/>
         <log level="full">
            <property name="after" value="afterTransform"/>
         </log>
         <send/>
      </outSequence>
   </target>
   <publishWSDL uri="file:repository/samples/resources/proxy/FayuanService.wsdl"/>
   <description/>
</proxy>
                                

<?xml version="1.0" encoding="ISO-8859-1"?>
<xsl:stylesheet version="2.0"
                xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
                xmlns:fn="http://www.w3.org/2005/02/xpath-functions"
                xmlns:ns="http://fayuanservice.wso2.org"
				xmlns:ax23="http://fayuanservice.wso2.org/xsd"
                exclude-result-prefixes="fn ns ax23">
    <xsl:output method="xml" omit-xml-declaration="yes" indent="yes"/>

    <xsl:template match="/">
        <xsl:apply-templates select="//ns:return"/>
    </xsl:template>

    <xsl:template match="ns:return">

        <ns:createFYComplainRecordResponse  xmlns:ns="http://fayuanservice.wso2.org">
		<ns:return  xmlns:ax231="http://fayuanservice.wso2.org/xsd">
               <ax231:complainant><xsl:value-of select="ax23:complainant"/></ax231:complainant>
			   <ax231:respondent><xsl:value-of select="ax23:respondent"/></ax231:respondent>
			   <ax231:info><xsl:value-of select="ax23:info"/></ax231:info>
			   <ax231:recordTime><xsl:value-of select="ax23:recordTime"/></ax231:recordTime>								 
			   <ax231:recordType><xsl:value-of select="translate(ax23:recordType,'01','LN')"/></ax231:recordType>
		</ns:return>
        </ns:createFYComplainRecordResponse>

    </xsl:template>
</xsl:stylesheet>

输入0，转换为L

输入1，转换为N

场景二：律师信息转换
描述：改变律师信息服务的响应消息标签，添加删除消息属性等。

1 创建查看律师信息服务

参见代码lawyerAxis2Service，打包为lawyerAxis2Service_1.0.0.aar服务发布。

2、创建代理服务

<?xml version="1.0" encoding="UTF-8"?>
<proxy xmlns="http://ws.apache.org/ns/synapse"
       name="DataTransformProxy"
       transports="https,http"
       statistics="enable"
       trace="enable"
       startOnLoad="true">
   <target>
      <inSequence>
         <send>
            <endpoint key="LawyerInfoEndpoint"/>
         </send>
      </inSequence>
      <outSequence>
         <log level="full">
            <property name="before" value="beforeTransform"/>
         </log>
         <xslt key="dataTransform.xslt"/>
         <log level="full">
            <property name="after" value="afterTransform"/>
         </log>
         <send/>
      </outSequence>
   </target>
   <publishWSDL uri="http://192.168.100.169:9763/services/LayerInfoService?wsdl"/>
   <description/>
</proxy>
                                

<?xml version="1.0" encoding="ISO-8859-1"?>
<xsl:stylesheet version="2.0"
                xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
                xmlns:fn="http://www.w3.org/2005/02/xpath-functions"
                xmlns:ns="http://lawyer.wso2.org"
				xmlns:ax219="http://lawyer.wso2.org/xsd"
                exclude-result-prefixes="fn ns ax219">
    <xsl:output method="xml" omit-xml-declaration="yes" indent="yes"/>

    <xsl:template match="/">
        <xsl:apply-templates select="//ns:return"/>
    </xsl:template>

    <xsl:template match="ns:return">

        <m:getLawyerInfoResponse xmlns:m="http://lawyer.wso2.org/xsd">
               <m:lAWYERLEVEL><xsl:value-of select="ax219:lawyerLevel"/></m:lAWYERLEVEL>
			   <m:lAWYERNAME><xsl:value-of select="ax219:lawyerName"/></m:lAWYERNAME>
			   <m:LAWYEROFFICE><xsl:value-of select="ax219:lawyerOffice"/></m:LAWYEROFFICE>
			   <m:LAWYERORIGIN><xsl:value-of select="ax219:lawyerOrigin"/></m:LAWYERORIGIN>
			   <m:LAWYERSEX><xsl:value-of select="ax219:lawyerSex"/></m:LAWYERSEX>
        </m:getLawyerInfoResponse>

    </xsl:template>
</xsl:stylesheet>

直接调用律师信息服务结果为：

转换后律师信息服务结果为：
