Spring3.0和Mybatis的集成,含事务配置
相对于hibernate来说，比较喜欢mybatis一些。虽然mybatis没有hibernate那么成熟,但可以手动控制sql语句怎么长。废话不多说，上代码。欢迎拍砖。Xml代码

鉴于网络参数和鉴权信息是经常变的，所以单独拿出来放在属性文件中了。spring-jdbc.properties内容如下:
Java代码
jdbc.driver=oracle.jdbc.driver.OracleDriver
jdbc.url=jdbc:oracle:thin:@localhost:1521:orcl
jdbc.username=admin
jdbc.password=pwd
jdbc.driver=oracle.jdbc.driver.OracleDriver
jdbc.url=jdbc:oracle:thin:@localhost:1521:orcl
jdbc.username=admin
jdbc.password=pwd
Mybatis中的拦截器和一些bean的配置信息就放在SqlMapConfig.xml这个文件中了
Xml代码
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE configuration
PUBLIC "-//ibatis.apache.org//DTD Config 3.0//EN"
"http://ibatis.apache.org/dtd/ibatis-3-config.dtd">
<configuration>
<!-- 要在environment之前 -->
<typeAliases>
<typeAlias type="com.jacarri.document.vo.WriteFileVo" alias="WriteFileVo" />
</typeAliases>
<plugins>
<plugin interceptor="com.jacarri.common.filter.PaginationInterceptor" />
<plugin interceptor="com.jacarri.common.filter.ColumnsControlInterceptor" />
</plugins>
</configuration>
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE configuration

<typeAliases>
<typeAlias type="com.jacarri.document.vo.WriteFileVo" alias="WriteFileVo" />
</typeAliases>
<plugins>
<plugin interceptor="com.jacarri.common.filter.PaginationInterceptor" />
<plugin interceptor="com.jacarri.common.filter.ColumnsControlInterceptor" />
</plugins>
</configuration>备注：两个interceptor，第一个是用来分页的，第二个是用来控制select语句中列名的，就不上代码了。想要的可以给我发消息。至于WriteFileVo就是一个普通的bean，如果你要用到缓存，记得bean要实现java.io.Serializable。
同时附上jar包清单(该清单是在搭建struts2+Spring3+Mybatis框架时用到的清单)
