sping struts2 ibatis 整合

整合ssi虽然原理比较简单，但在实际操作的时候还是容易出错的，在这里也记录一下...
各个组件的版本号：struts2.1 spring2.5 ibatis2.3
struts2.1需要的包
首先是struts2.1必须的包：

然后是要与spring集成需要的包：struts2-spring-plugin-2.1.6.jar

spring2.5需要的包
这里用的是集成了spring所有模块的包：spring.jar

ibatis2.3需要的包
ibatis-2.3.*.*.jar

sql-map-config.xml的配置

<!--<br /> <br /> Code highlighting produced by Actipro CodeHighlighter (freeware)<br /> http://www.CodeHighlighter.com/<br /> <br /> --><?xmlversion="1.0"encoding="UTF-8"?>
<!DOCTYPEsqlMapConfig
PUBLIC"-//ibatis.apache.org//DTDSQLMapConfig2.0//EN"
"http://ibatis.apache.org/dtd/sql-map-config-2.dtd">
<sqlMapConfig>
<settingsuseStatementNamespaces="true"/>
<sqlMapresource="ssi/persistance/sqlmap/user_SqlMap.xml"/>
</sqlMapConfig>

具体sql-map文件的配置，这里就不写了，我也是刚刚学习ibatis，呵呵，由于最近马上就要开发了，就找了工具来加快速度，ibatis官方提供的ibator（原来叫abator）这个工具相当猛啊，还在学习中...

在配置过程当中，特别需要注意各个配置文件的存放位置，比如对于applicationContext.xml来说，默认应该存放在WEB-INF文件夹中，如果想放到类路径上去，需要在web.xml里面配置，一般配置在web.xml的开头部分：

<!--<br /> <br /> Code highlighting produced by Actipro CodeHighlighter (freeware)<br /> http://www.CodeHighlighter.com/<br /> <br /> --><context-param>
<param-name>contextConfigLocation</param-name>
<param-value>
classpath:applicationContext.xml
</param-value>
</context-param>
