spring jdbc封装通用DAO方法

1、接口定义

package com.gkhb.mis.core.dao;

import java.util.List;
import java.util.Map;

import org.springframework.jdbc.core.SqlParameter;

/**
 * @corporation gkhb
 * @author 

 * @date 2008-4-9 下午03:03:54
 * @path com.gkhb.mis.core.dao
 * @description
 */
public interface IOperationGenericDao {
 
 public static final String DAO = "operationGenericDao";
 
 public Page findByPage(String sql, Page page, Object... values);

 public List<?> findRow(String sql, Object... values);

 public Map<?, ?> getRow(String sql, Object... values);

 public int saveRow(String sql, Object... values);

 public Map<?, ?> executeStroeProcedure(String procedureName,
   SqlParameter[] procedureParameters, Object... parameterValues);

}
2、接口实现

import org.springframework.jdbc.core.SqlParameter;
import org.springframework.jdbc.core.support.JdbcDaoSupport;
import org.springframework.jdbc.object.StoredProcedure;
