mybatis代码生成
自动生成 mybatis代码，特别是sqlmap文件，可以有效的减少dao等代码的重复劳动。eclipse中添加插件： mybatis Generator - http://mybatis.googlecode.com/svn/sub-projects/generator/trunk/eclipse/UpdateSite/
添加生成代码的配置文件

<!-- 生成DAO的类文件以及配置文件 -->
<daoGenerator targetPackage="test.dao" targetProject="Test-web"

<!-- 避免生成一大堆Example方法,代码看去清晰一些 -->
<table tableName="user" domainObjectName="User"
enableCountByExample="false" enableUpdateByExample="false"
enableDeleteByExample="false" enableSelectByExample="false"
selectByExampleQueryId="false">
<!-- 去除一列，这样 PASSWORD这列就不会生成
<ignoreColumn column="PASSWORD"/>
-->
<!-- columnOverride 将数据库字段对应成javabean里面的字段-->
<columnOverride column="USERID" property="userid" />
<columnOverride column="USERNAME" property="username" />
<columnOverride column="PASSWORD" property="password" />
</table>

在文件上点击鼠标右键，可以看到插件生成的选项，选择即可生成代码
