2024-06-07 05:36:50
1.与allColumn定义
<resultMap id="sysuserDtoMap" type="com.bsj.wms.pojo.dto.SysuserDto"><result column="UserID" property="userid"/><result column="UserCode" property="usercode"/><result column="UserName" property="username"/><result column="UserPwd" property="userpwd"/><result column="UserType" property="usertype"/><result column="DEPID" property="depid"/><result column="UserAddress" property="useraddress"/><result column="UserMobile" property="usermobile"/><result column="UserPhone" property="userphone"/><result column="UserMail" property="usermail"/><result column="EMID" property="emid"/><result column="UserLock" property="userlock"/><result column="UserLockTime" property="userlocktime"/><result column="UserMemo" property="usermemo"/><result column="UserUpdate" property="userupdate"/><result column="TpUploading" property="tpuploading"/></resultMap><!--所有字段--><sql id="allColumn">UserID,UserCode,UserName,UserPwd,UserType,DEPID,UserAddress,UserMobile,UserPhone,UserMail,EMID,UserLock,UserLockTime,UserMemo,UserUpdate,TpUploading</sql>
2.正常CRUD操作 单条数据操作(以正常User表为例)
2.1.插入
<insert id="save" useGeneratedKeys="true" keyProperty="userid">insert into SysUser(UserCode,UserName,UserPwd,UserType,DEPID,UserAddress,UserMobile,UserPhone,UserMail,EMID,UserLock,UserLockTime,UserMemo,UserUpdate,TpUploading)values (<trim suffixOverrides=",">#{usercode},#{username},#{userpwd},#{usertype},#{depid},#{useraddress},#{usermobile},#{userphone},#{usermail},#{emid},#{userlock},#{userlocktime},#{usermemo},#{userupdate},#{tpuploading},</trim>)</insert>
2.2.通过ID物理删除
<delete id="deleteById">delete from SysUserwhere UserID = #{userid}
</delete>
2.3.根据多个条件物理删除
<delete id="delete">delete from SysUser where 1=1<if test="userid != null">and UserID = #{userid}</if><if test="usercode != null and ''!= usercode">and UserCode = #{usercode}</if><if test="username != null and ''!= username">and UserName = #{username}</if><if test="userpwd != null and ''!= userpwd">and UserPwd = #{userpwd}</if><if test="usertype != null and ''!= usertype">and UserType = #{usertype}</if><if test="depid != null">and DEPID = #{depid}</if><if test="useraddress != null and ''!= useraddress">and UserAddress = #{useraddress}</if><if test="usermobile != null and ''!= usermobile">and UserMobile = #{usermobile}</if><if test="userphone != null and ''!= userphone">and UserPhone = #{userphone}</if><if test="usermail != null and ''!= usermail">and UserMail = #{usermail}</if><if test="emid != null">and EMID = #{emid}</if><if test="userlock != null">and UserLock = #{userlock}</if><if test="usermemo != null and ''!= usermemo">and UserMemo = #{usermemo}</if><if test="tpuploading != null">and TpUploading = #{tpuploading}</if></delete>
2.4.通过ID逻辑删除
<update id="logicDeleteById">update SysUser<trim prefix="set" suffixOverrides=",">is_del = 2</trim>where UserID = #{userid}
</update>
2.5.根据多个条件逻辑删除
<update id="logicDelete">update SysUser<trim prefix="set" suffixOverrides=",">is_del = 2</trim>where 1=1<if test="usercode != null and ''!= usercode">and UserCode = #{usercode}</if><if test="username != null and ''!= username">and UserName = #{username}</if><if test="userpwd != null and ''!= userpwd">and UserPwd = #{userpwd}</if><if test="usertype != null and ''!= usertype">and UserType = #{usertype}</if><if test="depid != null">and DEPID = #{depid}</if><if test="useraddress != null and ''!= useraddress">and UserAddress = #{useraddress}</if><if test="usermobile != null and ''!= usermobile">and UserMobile = #{usermobile}</if><if test="userphone != null and ''!= userphone">and UserPhone = #{userphone}</if><if test="usermail != null and ''!= usermail">and UserMail = #{usermail}</if><if test="emid != null">and EMID = #{emid}</if><if test="userlock != null">and UserLock = #{userlock}</if><if test="usermemo != null and ''!= usermemo">and UserMemo = #{usermemo}</if><if test="tpuploading != null">and TpUploading = #{tpuploading}</if></update>
2.6.编辑
<update id="update">update SysUser<trim prefix="set" suffixOverrides=","><if test="usercode != null and ''!= usercode">UserCode = #{usercode},</if><if test="username != null and ''!= username">UserName = #{username},</if><if test="userpwd != null and ''!= userpwd">UserPwd = #{userpwd},</if><if test="usertype != null and ''!= usertype">UserType = #{usertype},</if><if test="depid != null">DEPID = #{depid},</if><if test="useraddress != null and ''!= useraddress">UserAddress = #{useraddress},</if><if test="usermobile != null and ''!= usermobile">UserMobile = #{usermobile},</if><if test="userphone != null and ''!= userphone">UserPhone = #{userphone},</if><if test="usermail != null and ''!= usermail">UserMail = #{usermail},</if><if test="emid != null">EMID = #{emid},</if><if test="userlock != null">UserLock = #{userlock},</if><if test="userlocktime != null">UserLockTime = #{userlocktime},</if><if test="usermemo != null and ''!= usermemo">UserMemo = #{usermemo},</if><if test="userupdate != null">UserUpdate = #{userupdate},</if><if test="tpuploading != null">TpUploading = #{tpuploading},</if></trim>where UserID = #{userid}</update>
2.7.单个查询
<select id="findOne" resultMap="sysuserDtoMap">select top 1<include refid="allColumn"/>from SysUserwhere 1=1<if test="sysuser.userid != null">and UserID = #{sysuser.userid}</if><if test="sysuser.usercode != null and ''!= sysuser.usercode">and UserCode = #{sysuser.usercode}</if><if test="sysuser.username != null and ''!= sysuser.username">and UserName = #{sysuser.username}</if><if test="sysuser.userpwd != null and ''!= sysuser.userpwd">and UserPwd = #{sysuser.userpwd}</if><if test="sysuser.usertype != null and ''!= sysuser.usertype">and UserType = #{sysuser.usertype}</if><if test="sysuser.depid != null">and DEPID = #{sysuser.depid}</if><if test="sysuser.useraddress != null and ''!= sysuser.useraddress">and UserAddress = #{sysuser.useraddress}</if><if test="sysuser.usermobile != null and ''!= sysuser.usermobile">and UserMobile = #{sysuser.usermobile}</if><if test="sysuser.userphone != null and ''!= sysuser.userphone">and UserPhone = #{sysuser.userphone}</if><if test="sysuser.usermail != null and ''!= sysuser.usermail">and UserMail = #{sysuser.usermail}</if><if test="sysuser.emid != null">and EMID = #{sysuser.emid}</if><if test="sysuser.userlock != null">and UserLock = #{sysuser.userlock}</if><if test="sysuser.usermemo != null and ''!= sysuser.usermemo">and UserMemo = #{sysuser.usermemo}</if><if test="sysuser.tpuploading != null">and TpUploading = #{sysuser.tpuploading}</if></select>
2.8.查询全部
<select id="findAll" resultMap="sysuserDtoMap">select<include refid="allColumn"/>from SysUserwhere 1=1<if test="sysuser.userid != null">and UserID = #{sysuser.userid}</if><if test="sysuser.usercode != null and ''!= sysuser.usercode">and UserCode = #{sysuser.usercode}</if><if test="sysuser.username != null and ''!= sysuser.username">and UserName = #{sysuser.username}</if><if test="sysuser.userpwd != null and ''!= sysuser.userpwd">and UserPwd = #{sysuser.userpwd}</if><if test="sysuser.usertype != null and ''!= sysuser.usertype">and UserType = #{sysuser.usertype}</if><if test="sysuser.depid != null">and DEPID = #{sysuser.depid}</if><if test="sysuser.useraddress != null and ''!= sysuser.useraddress">and UserAddress = #{sysuser.useraddress}</if><if test="sysuser.usermobile != null and ''!= sysuser.usermobile">and UserMobile = #{sysuser.usermobile}</if><if test="sysuser.userphone != null and ''!= sysuser.userphone">and UserPhone = #{sysuser.userphone}</if><if test="sysuser.usermail != null and ''!= sysuser.usermail">and UserMail = #{sysuser.usermail}</if><if test="sysuser.emid != null">and EMID = #{sysuser.emid}</if><if test="sysuser.userlock != null">and UserLock = #{sysuser.userlock}</if><if test="sysuser.usermemo != null and ''!= sysuser.usermemo">and UserMemo = #{sysuser.usermemo}</if><if test="sysuser.tpuploading != null">and TpUploading = #{sysuser.tpuploading}</if></select>
3.批量操作
3.1.批量物理删除
<delete id="deleteListByIds">delete from SysUserwhere UserID in<foreach collection="list" item="item" index="index" open="(" separator="," close=")">#{item}</foreach></delete>
批量逻辑删除
<update id="logicDeleteListByIds">update SysUser<trim prefix="set" suffixOverrides=",">is_del = 2</trim>where UserID in<foreach collection="list" item="item" index="index" open="(" separator="," close=")">#{item}</foreach></update>
批量保存数据
<insert id="saveList" useGeneratedKeys="true" keyProperty="userid">insert into SysUser(UserCode,UserName,UserPwd,UserType,DEPID,UserAddress,UserMobile,UserPhone,UserMail,EMID,UserLock,UserLockTime,UserMemo,UserUpdate,TpUploading)values<foreach collection="list" item="item" index="index" separator=",">(<trim suffixOverrides=",">#{item.usercode},#{item.username},#{item.userpwd},#{item.usertype},#{item.depid},#{item.useraddress},#{item.usermobile},#{item.userphone},#{item.usermail},#{item.emid},#{item.userlock},#{item.userlocktime},#{item.usermemo},#{item.userupdate},#{item.tpuploading},</trim>)</foreach></insert>
