5.Ibatis配置文件：

<!DOCTYPE sqlMapConfig         
    PUBLIC "-//ibatis.apache.org//DTD SQL Map Config 2.0//EN"         
    "http://ibatis.apache.org/dtd/sql-map-config-2.dtd">
<sqlMapConfig>
	<sqlMap resource="com/cjh/model/Userinfo.xml" />
</sqlMapConfig>

6.操作語句配置文件：

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE sqlMap      
    PUBLIC "-//ibatis.apache.org//DTD SQL Map 2.0//EN"      
    "http://ibatis.apache.org/dtd/sql-map-2.dtd">
    
 <sqlMap>
 	<typeAlias alias="Userinfo" type="com.cjh.model.Userinfo"/>
    <insert id="saveUser" parameterClass="Userinfo">
		<![CDATA[
				INSERT INTO
				user_info(
				username,
				password
				) VALUES (
				    #username#,
				    #password#
				)
		]]> 
	</insert>
	
</sqlMap>

7.BaseDao代碼：

import javax.annotation.PostConstruct;
import javax.annotation.Resource;

import org.springframework.orm.ibatis.support.SqlMapClientDaoSupport;

import com.ibatis.sqlmap.client.SqlMapClient;

public class BaseDao extends SqlMapClientDaoSupport{
	@Resource
	private SqlMapClient sqlMapClient;

	@PostConstruct
	public void initSqlMapClient() {
		super.setSqlMapClient(sqlMapClient);
	}
}
