背景
不同的合作银行对应的外部接口是不一样的,我们需要把外部这些变化不定的接口格式,转换为我们银保通系统可以识别的内部接口.Smooks可以很好的解决这一问题.并且,当合作银行的接口随着业务的变化而发生变化时,smooks只需要通过变更转换模板,就可以实现对变化后接口的支持。
Smooks框架可以在smooks的官网www.smooks.org (需要FQ软)下载。本文smooks的版本是smooks-1.4。在其lib文件夹中是所需要的jar包。将所有jar包导入你的工程中就能使用smooks进行报文解析了。
现在说明下面两种种转换XmlToXml,CsvToXml.
1. Xml To Xml
说明xml转换为xml在smooks的配置中有两种方式一种是通过xsl模板控制一种是通过freemaker模板控制。其中后者比较灵活格式容易控制推荐使用后者。

/smooks-resource-list说明此配置文件的作用是通过内置xsl的配置将input-message.xml中的一些标签名替换掉例如
将TRANSTYPE替换成/SVCTYPE新增加一些丢失的标签例如SVCDETAILQueryPolicyByProposalNoService/SVCDETAIL并且将BODY 标签下的内容改为一个list类型的标签。结果请对照下面out.xml。
③通过如下程序可读取输入报文input-message.xml和配置文件smooks-config.xml并产生输出文件out.xml.

Smooks 还可以进行Json, EDI 等常用数据格式的文件转化。具体方法请参加从smooks官网下载下来的smooks-1.4文件夹中/docs/SmooksUserGuide_v1.4.html的说明。具体的程序可以参加\examples下的例子。 转载于:https://www.cnblogs.com/svennee/p/4078883.html
