最新開源DBLayer，原來數據庫操作可以這么簡單

DBLayer，我最近開源的數據庫輕量級orm框架，目前支持sqlserver、mysql、oracle, 特別做了分頁的封裝。

這個框架從七八年前開始逐漸升級而來，也經歷了不少項目，希望可以將大家從sql字符串中解放出來。

訪問代碼案例

var id = TheService.InsertEntity<SysLog, long>(
        () => new SysLog()
        {
            LogId = -1,
            LogContentJson = "測試",
            LogCreater = "測試",
            LogCreateTime = DateTime.Now,
            LogType = "1"
        });

分頁操作

        /// <summary>
        /// 分頁查詢
        /// </summary>
        /// <param name="condition">查詢條件</param>
        /// <returns></returns>
        public IEnumerable<SysUser> Seach(SysUserCondition.Search condition)
        {
            var page = new Pager<SysUserCondition.Search>()
            {
                Condition = condition,
                Table = "sys_user",
                Key = "user_id",
                Order = string.Empty,
                Field = "*",
                WhereAction = (Condition, Where, Paramters) =>
                {
                    if (!string.IsNullOrEmpty(Condition.UserName))
                    {
                        Where.Append("AND user_name LIKE @user_name ");
                        Paramters.Add(base.CreateParameter("@user_name", string.Concat("%", Condition.UserName, "%")));
                    }
                    if (!string.IsNullOrEmpty(Condition.UserEmail))
                    {
                        Where.Append("AND user_email LIKE @user_email ");
                        Paramters.Add(base.CreateParameter("@user_email", string.Concat("%", Condition.UserEmail, "%")));
                    }
                    if (!string.IsNullOrEmpty(Condition.UserMobile))
                    {
                        Where.Append("AND user_mobile LIKE @user_mobile ");
                        Paramters.Add(base.CreateParameter("@user_mobile", string.Concat("%", Condition.UserMobile, "%")));
                    }
                }
            };

            var result = base.GetResultByPager<SysUser, SysUserCondition.Search>(page);
            return result;
        }

推薦和spring 配合使用，具體配置代碼請進入源碼查看。

同時在spring 配置多個數據庫連接，支持數據庫連接字符串密碼加密。只需要在 passwordKey加入密鑰

  <object id="sql_wxius_string_server" type="DBLayer.Core.ConnectionString, DBLayer.Core" singleton="true">
    <property name="Properties">
      <name-values>
        <add key="userid" value="sa" />
        <add key="password" value="***" />
        <add key="passwordKey" value="" />
        <add key="database" value="wxius" />
        <add key="datasource" value="." />
      </name-values>
    </property>
    <property name="ConnectionToken" value="Password=${password};Persist Security Info=True;User ID=${userid};Initial Catalog=${database};Data Source=${datasource};pooling=true;min pool size=5;max pool size=10" />
  </object>

數據庫唯一標識除了可以數據自動編碼，還支持在代碼端自動 生成 GUID 和 時間點。下面代碼是uuid,時間點並按照順序生成的自動編號

  <object id="uuidGenerator" type="DBLayer.Persistence.UUIDGenerator, DBLayer.Persistence" singleton="true" >
    <!--workerId:區域(機房):3 bits-->
    <constructor-arg name="workerId" value="1"/>
    <!--regionId:機器編號:10 bits-->
    <constructor-arg name="regionId" value="1"/>
    <!--twepoch:基准時間:Thu, 04 Nov 2010 01:42:54 GMT-->
    <!--(long)(DateTime.UtcNow - new DateTime(1970, 1, 1, 0, 0, 0, DateTimeKind.Utc)).TotalMilliseconds-->
    <constructor-arg name="twepoch" value="1288834974657"/>
  </object>
