配置文件主要是
SqlMapConfig.xml
o properties
o settings
o typeAliases
o typeHandlers
o objectFactory
o plugins
o environments
environment
• transactionManager
• dataSource
o mappers
properties用来定义外部properties配置文件信息。比如
<properties resource="org/apache/ibatis/example/config.properties"> <property name="username" value="dev_user"/> <property name="password" value="F2Fa3!33TYyg"/> properties>
settings 设置数据库相关属性
typeAliases设置别名，其实也可以在mappers里面的具体mapper里设置
typeHandlers设置别名处理器
environments 运行环境参数等等
mappers有两种方式配置
// Using classpath relative resources
<mappers>
<mapper resource="org/apache/ibatis/builder/AuthorMapper.xml"/>
<mapper resource="org/apache/ibatis/builder/BlogMapper.xml"/>
<mapper resource="org/apache/ibatis/builder/PostMapper.xml"/>
mappers>
// Using url fully qualified paths
<mappers>
<mapper url="file:///var/sqlmaps/AuthorMapper.xml"/>
<mapper url="file:///var/sqlmaps/BlogMapper.xml"/>
<mapper url="file:///var/sqlmaps/PostMapper.xml"/>
mappers>
上面的配置没太多的技巧可言，相对与具体的sql-map来说。下面就说说sql-map的配置
