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.

One high level model for the order (header etc) and then one per order-item. These models are used in the FreeMarker templating resources defined below. You need to make sure you set the selector such that the total memory footprint is as low as possible. In this example, the order model will contain everything accept the order-item data (the main bulk of data in the message).

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
