springboot+Mybatis批量增删改查（java批量添加、修改带非空判断）

1、批量添加--xml代码

<insert >
        INSERT INTO sw_rs_set_holdstandard (
            hold_createtime,
            hold_flag,
            company_id,
            hold_type,
            train_id,
            hold_level3,
            hold_level4
        )
        values
        <foreach collection="list" item="item" index="index"  separator=",">
            <trim prefix=" (" suffix=")" suffixOverrides="," >
                now(),1,#{item.companyIdbs,jdbcType=BIGINT}
                <if test="item.holdType!=null">
                    ,#{item.holdType,jdbcType=BIGINT}
                </if>
                <if test="item.holdType==null">
                    ,0
                </if>
                ,#{item.trainIdbs,jdbcType=BIGINT}
                <if test="item.holdLevel3!=null">
                    ,#{item.holdLevel3,jdbcType=BIGINT}
                </if>
                <if test="item.holdLevel3==null">
                    ,0
                </if>
                <if test="item.holdLevel4!=null">
                    ,#{item.holdLevel4,jdbcType=BIGINT}
                </if>
                <if test="item.holdLevel4==null">
                    ,0
                </if>
            </trim>
        </foreach>
    </insert>

2、批量添加--调用

/**
     * 批量添加
     */
    int insertBatchList(List<SwRsSetHoldstandardEntity> list);

3、批量修改--xml代码

<update >
        UPDATE sw_rs_set_holdstandard
        <trim prefix="set" suffixOverrides=",">
            <trim prefix="hold_updatetime =case" suffix="end,">
                <foreach collection="list" item="item">
                    when hold_id = #{item.holdId} then now()
                </foreach>
            </trim>
            <trim prefix="hold_level3 =case" suffix="end,">
                <foreach collection="list" item="item" index="index">
                    <if test="item.holdLevel3!=null">
                        when hold_id = #{item.holdId} then #{item.holdLevel3}
                    </if>
                </foreach>
            </trim>
            <trim prefix="hold_level4 =case" suffix="end,">
                <foreach collection="list" item="item">
                    <if test="item.holdLevel4!=null">
                        when hold_id = #{item.holdId} then #{item.holdLevel4}
                    </if>
                </foreach>
            </trim>
        </trim>
        where hold_id in
        <foreach collection="list" index="index" item="item" separator="," open="(" close=")">
            #{item.holdId}
        </foreach>
    </update>

4、批量修改--调用

/**
     * 批量修改
     */
    int updateBatchList(List<SwRsSetHoldstandardEntity> list);

5、批量删除--xml

<delete >
        delete from description
        where id
        in
        <foreach collection="list" item="id" open="(" separator="," close=")">
            #{id}
        </foreach>
    </delete>

6、查询xml

<select >
        SELECT
        tp.train_level trainLevel,tp.train_id trainIdbs,tp.train_postname trainPostname,-1 companyIdbs
        ,case hs.hold_type when 1 then '资源' when 2 then '客源' else '' end holdTypeName
        ,ifnull(cp.co_name,'集团') coName,hs.*
        ,<include ref>
        from sw_rs_trainingrepository tp
        LEFT JOIN sw_rs_set_holdstandard hs on hs.train_id=tp.train_id and hs.hold_flag=1
        <if test="companyId!=null">
            and hs.company_id=#{companyId}
        </if>
        <if test="holdType!=null">
            and hs.hold_type=#{holdType}
        </if>
        LEFT JOIN sw_bs_company cp on cp.company_id=hs.company_id
        where tp.train_isenable=1
        <if test="trainPostname!=null and trainPostname!=''">
            and tp.train_postname=#{trainPostname}
        </if>
        order by tp.train_rank asc
    </select>
