Insql 是一个轻量级的.NET ORM类库。对象映射基于Dapper, Sql配置灵感来自于Mybatis。
功能特点:
支持 DoNet Core 2.0+ && DotNet Framework 4.6.1+
支持依赖注入系统
MyBatis sql xml 语法
多数据库支持
灵活扩展性
使用简单
添加Insql
public void ConfigureServices(IServiceCollection services) { services.AddInsql(); services.AddInsqlDbContext<UserDbContext>(options => { //options.UseSqlServer(this.Configuration.GetConnectionString("sqlserver")); options.UseSqlite(this.Configuration.GetConnectionString("sqlite")); }); }
创建 DbContext
public class UserDbContext : Insql.DbContext { public UserDbContext(Insql.DbContextOptions<UserDbContext> options) : base(options) { } public IEnumerable<UserInfo> GetUserList(string userName) { //sqlId = "GetUserList" //sqlParam is PlainObject or IDictionary<string,object> return this.Query<UserInfo>(nameof(GetUserList), new { userName, userGender = Gender.W }); } public void InsertUser(UserInfo info) { var userId = this.ExecuteScalar<int>(nameof(InsertUser),info); info.UserId = userId; } public void UpdateUserSelective(UserInfo info) { this.Execute(nameof(UpdateUserSelective), info); } } //user model public class UserInfo { public int UserId { get; set; } public string UserName { get; set; } public Gender? UserGender { get; set; } } public enum Gender { M, W }
创建 DbContext.insql.xml
创建UserDbContext.insql.xml 文件并且修改这个文件的属性为嵌入式文件类型 . insql type 与 UserDbContext 类型对应.
UserDbContext.insql.xml
嵌入式文件
insql type
UserDbContext
<insql type="Example.Domain.Contexts.UserDbContext,Example.Domain" > <sql id="selectUserColumns"> select user_id as UserId,user_name as UserName,user_gender as UserGender from user_info </sql> <select id="GetUserList"> <include refid="selectUserColumns" /> <where> <if test="userName != null"> <bind name="likeUserName" value="'%' + userName + '%'" /> user_name like @likeUserName </if> <if test="userGender != null and userGender != 'M' "> and user_gender = @userGender </if> </where> order by user_id </select> <insert id="InsertUser"> insert into user_info (user_name,user_gender) values (@UserName,@UserGender); select last_insert_rowid() from user_info; </insert> <update id="UpdateUserSelective"> update user_info <set> <if test="UserName != null"> user_name=@UserName, </if> <if test="UserGender != null"> user_gender=@UserGender </if> </set> where user_id = @UserId </update> </insql>
使用 DbContext
使用UserDbContext 在Domain Service中或者Web Controller中
public class ValuesController : ControllerBase { private readonly UserDbContext userDbContext; public ValuesController(UserDbContext userDbContext) { this.userDbContext = userDbContext; } [HttpGet] public ActionResult<IEnumerable<string>> Get() { //可以这样使用事务 this.userDbContext.DoWithTransaction(() => { var userInfo = new Domain.UserInfo { UserName = "loveW", UserGender = Domain.Gender.M }; this.userDbContext.InsertUser(userInfo); this.userDbContext.UpdateUserSelective(new Domain.UserInfo { UserId = userInfo.UserId, UserName = "loveWWW", }); }); var list = this.userDbContext.GetUserList("love"); //todo return } }
