最新开源DBLayer，原来数据库操作可以这么简单

DBLayer，我最近开源的数据库轻量级orm框架，目前支持sqlserver、mysql、oracle, 特别做了分页的封装。

这个框架从七八年前开始逐渐升级而来，也经历了不少项目，希望可以将大家从sql字符串中解放出来。

访问代码案例

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

分页操作

        /// <summary>
        /// 分页查询
        /// </summary>
        /// <param name="condition">查询条件</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;
        }

推荐和spring 配合使用，具体配置代码请进入源码查看。

同时在spring 配置多个数据库连接，支持数据库连接字符串密码加密。只需要在 passwordKey加入密钥

  <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>

数据库唯一标识除了可以数据自动编码，还支持在代码端自动 生成 GUID 和 时间点。下面代码是uuid,时间点并按照顺序生成的自动编号

  <object id="uuidGenerator" type="DBLayer.Persistence.UUIDGenerator, DBLayer.Persistence" singleton="true" >
    <!--workerId:区域(机房): bits-->
    <constructor-arg name="workerId" value=""/>
    <!--regionId:机器编号: bits-->
    <constructor-arg name="regionId" value=""/>
    <!--twepoch:基准时间:Thu,  Nov  :: GMT-->
    <!--(long)(DateTime.UtcNow - new DateTime(, , , , , , DateTimeKind.Utc)).TotalMilliseconds-->
    <constructor-arg name="twepoch" value=""/>
  </object>
