以上是映射配置文件

 下面是SqlMap.config 文件

<?xml version="1.0" encoding="utf-8"?>
<sqlMapConfig xmlns="http://ibatis.apache.org/dataMapper" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
  <properties resource="../../config/properties.config"/>
  <settings>
    <setting useStatementNamespaces="false"/>
  </settings>
  <providers  resource="providers.config"/>
  <database>
    <provider name="sqlServer2008"/>
    <dataSource name="test" connectionString="server=GSHC-LIWC8;uid=sa; pwd=111111;database=Test"/>
  </database>
  <sqlMaps>
    <sqlMap  resource="../../config/test/BlogContent.xml"/>
  </sqlMaps>
</sqlMapConfig>
