代碼裏有用到 IBatchDao 公用接口, IBaseDao接口 IBaseService接口, IBatchService 接口

附公用dao接口文件:

IBaseDao.java

/**

public interface IBaseDao<T, P extends Serializable> extends IDao {
	
	/**

     */
    public T create(T t, P p);

    /**

    public boolean update(T t, P p);
    
    /**

    public List<T> findAll(String sqlExpression, P p);
    
}

IBatchDao.java

package com.test;

import java.io.Serializable;
import java.util.*;

/**

}

說明:  IBaseDao 與 IBaseService接口內容相同, IBatchDao 與IBatchService 相同, 只是爲了分層.

BaseMdbDaoSupport 可以用spring原生 JdbcDaoSupport 代替, 可能有些方法沒有, 但是差不多.

SupDto 是上下文對象, 比如查詢數據的雲服務器名稱, 或者數據源名稱, 因爲在分庫系統, 雲庫系統數據存在不同的數據庫.

另外在 SupDto 也包含了分頁對象 PageDto 的參數.

JdbcDataUtils; SqlStringUnits; 這三個只是轉換工具, 自己可以修改代碼不使用它

SqlCacheUnits; 是爲了緩存最近1000條 sql語句, 方便顯示給後臺維護人員的.
