要根據id批量跟新name，age，modifiedDate，mapper.xml文件如下
<update id="batchUpdate">
update direct_bank_sys_param
<trim prefix="set" suffixOverrides=",">
<trim prefix="name=case" suffix="end,">
<foreach collection="list" item="i" index="index">
<if test="i.name!=null">
when id=#{i.id} then #{i.name}
</if>
</foreach>
</trim>
<trim prefix="age=case" suffix="end,">
<foreach collection="list" item="i" index="index">
<if test="i.age!=null">
when id=#{i.id} then #{i.age}
</if>
</foreach>
</trim>
<trim prefix=" modifier =case" suffix="end,">
<foreach collection="list" item="i" index="index">
<if test="i.modifier!=null">
when id=#{i.id} then #{i.modifier}
</if>
</foreach>
</trim>
</trim>
where
<foreach collection="list" separator="or" item="i" index="index">
id=#{i.id}
</foreach>
</update>
