Ibatis学习3--操作数据库(插入删除更新修改)

<?xml version="1.0" encoding="utf-8" ?><sqlMap namespace="Ibatis" xmlns="http://ibatis.apache.org/mapping" xmlns:xls="http://www.w3.org/2001/XMLSchema-instance">  <resultMaps>    <resultMap id="blogcontent" Class="StudyDemo.Model.Blog">      <result property="Id" column="Id" />      <result property="No" column="TestNo"/>      <result property="Title" column="TestTitle"/>      <result property="Content" column="TestContent"/>    </resultMap>  </resultMaps>  <statements>    <sql id="order">      order by Id desc    </sql>    <select id="selectAllBlog" resultMap="blogcontent">      select * from blogcontent      <inclued refid="order"/>    </select>    <select id="selectAllBlogOrderbyNodesc" resultMap="blogcontent" parameterClass="StudyDemo.Model.Blog" extends="selectAllBlog">      where TestNo =#No#      <include refid="order"/>    </select>    <insert id="InsertBlogContent" resultMap="blogcontent">      Insert Into BlogContent (TestNo,TestTitle,TestContent) values(#No#,#Title#,#Content#)      <selectKey  type="post" resultClass="int" property="Id">        select CAST(@@IDENTITY as int) as Id      </selectKey >    </insert>    <update id="UpdateBlogContent" resultMap="blogcontent">      update blogcontent set testNo=#No#,TestTitle=#Title#,TestContent=#Content# where Id=#Id#    </update>    <delete id="deleteBlogContent" resultMap="blogcontent">      delete from blogcontent where id=#Id#    </delete>  </statements></sqlMap>

以上是映射配置文件

 下面是SqlMap.config 文件

<?xml version="1.0" encoding="utf-8"?><sqlMapConfig xmlns="http://ibatis.apache.org/dataMapper" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">  <properties resource="../../config/properties.config"/>  <settings>    <setting useStatementNamespaces="false"/>  </settings>  <providers  resource="providers.config"/>  <database>    <provider name="sqlServer2008"/>    <dataSource name="test" connectionString="server=GSHC-LIWC8;uid=sa; pwd=111111;database=Test"/>  </database>  <sqlMaps>    <sqlMap  resource="../../config/test/BlogContent.xml"/>  </sqlMaps></sqlMapConfig>

 

代码Dao文件

using System;using System.Collections.Generic;using IBatisNet.DataMapper;using IBatisNet.DataMapper.Configuration;using StudyDemo.Model;namespace StudyDemo.Dao{    public class BlogContentDao    {        protected ISqlMapper _Mapper;        public BlogContentDao(string sqlMappType = "")        {            if (sqlMappType.Equals("Test",StringComparison.OrdinalIgnoreCase))            {                var builder = new DomSqlMapBuilder();                _Mapper = builder.Configure(@"../../Config/test/SqlMap.config");            }            else            {                _Mapper = Mapper.Instance();            }        }        public IList<BlogContent> GetList()        {            ISqlMapper mapper = Mapper.Instance();            IList<BlogContent> listBlogContent = mapper.QueryForList<BlogContent>("SelectAllBlogContenty", null);            return listBlogContent;        }        public IList<BlogContent> GetBlogContents()        {            DomSqlMapBuilder builder = new DomSqlMapBuilder();            ISqlMapper mapper = builder.Configure(@"../../Config/SqlMap.config");            IList<BlogContent> listBlgContent = mapper.QueryForList<BlogContent>("SelectAllBlogContent", null);            return listBlgContent;        }        public IList<Blog> GetBlogContentlist()        {            DomSqlMapBuilder builder = new DomSqlMapBuilder();            ISqlMapper mapper = builder.Configure(@"../../Config/test/SqlMap.config");            IList<Blog> listBlgContent = mapper.QueryForList<Blog>("selectAllBlogOrderbyNodesc", null);            return listBlgContent;        }        public IList<Blog> GetBlogContentsTest()        {            DomSqlMapBuilder builder = new DomSqlMapBuilder();            ISqlMapper mapper = builder.Configure(@"../../Config/test/SqlMap.config");            IList<Blog> listBlgContent = mapper.QueryForList<Blog>("selectAllBlog", null);            return listBlgContent;        }        public IList<Blog> GetBlogContentsOrderbyNoDesc()        {            DomSqlMapBuilder builder = new DomSqlMapBuilder();            ISqlMapper mapper = builder.Configure(@"../../Config/test/SqlMap.config");            Blog t = new Blog() { No = "01" };            IList<Blog> listBlgContent = mapper.QueryForList<Blog>("selectAllBlogOrderbyNodesc", t);            return listBlgContent;        }        public IList<Blog> GetBlogContentsOrderbyNoDesc1()        {            DomSqlMapBuilder builder = new DomSqlMapBuilder();            ISqlMapper mapper = builder.Configure(@"../../Config/test/SqlMap.config");            Blog t = new Blog() { No = "01" };            IList<Blog> listBlgContent = mapper.QueryForList<Blog>("selectAllBlogOrderbyNodesc1", t);            return listBlgContent;        }        public int InsertBlogContent(Blog b)        {            var builder = new DomSqlMapBuilder();            var mapper = builder.Configure(@"../../Config/test/SqlMap.config");            object test = mapper.Insert("InsertBlogContent", b);            return (int)test;        }        public void UpdateBlogContent(Blog b)        {            var builder = new DomSqlMapBuilder();            var mapper = builder.Configure(@"../../Config/test/SqlMap.config");            var t = mapper.Update("UpdateBlogContent", b);        }        public void DeleteBlogContent(Blog b)        {            _Mapper.Delete("deleteBlogContent", b);        }    }}

 

调用测试代码

using System;using StudyDemo.Dao;using StudyDemo.Model;namespace StudyDemo{    class Program    {        private static void Main(string[] args)        {            #region test select            //{            //    var dao = new BlogContentDao();            //    var listBlogContent = dao.GetBlogContentsTest();            //    foreach (var blogContent in listBlogContent)            //    {            //        Console.WriteLine(blogContent.Title + "---" + blogContent.Content);            //    }            //}            //{            //    var dao = new BlogContentDao();            //    var listBlogContent = dao.GetBlogContents();            //    foreach (var blogContent in listBlogContent)            //    {            //        Console.WriteLine(blogContent.TestTitle + "---" + blogContent.TestContent);            //    }            //}            //{            //    var dao = new BlogContentDao();            //    var listBlogContent = dao.GetBlogContentsOrderbyNoDesc();            //    foreach (var blogContent in listBlogContent)            //    {            //        Console.WriteLine(blogContent.Title + "---" + blogContent.Content);            //    }            //    Console.ReadKey();            //}            #endregion            #region test insert            //{            //    var dao = new BlogContentDao();            //    var insertblog = new Blog()            //    {            //        No = "04",            //        Title = "testInsert",            //        Content = "testContent"            //    };            //    var r = dao.InsertBlogContent(insertblog);            //    Console.WriteLine(r);            //    Console.ReadKey();            //}            #endregion            #region test update            //{            //    var dao = new BlogContentDao();            //    var insertblog = new Blog()            //    {            //        Id = 5,            //        No = "05",            //        Title = "testInsert5",            //        Content = "testContent5"            //    };            //    dao.UpdateBlogContent(insertblog);            //    Console.ReadKey();            //}            #endregion            #region test delete            {                var dao = new BlogContentDao("test");                var deleteBlog = new Blog() {Id=4};                dao.DeleteBlogContent(deleteBlog);            }            #endregion        }    }}
