1 Array
<select id="queryPojoById" parameterType="String[]" resultMap="pojo"> select * from t_table where id in <foreach collection="array" index="index" item="id" open="(" separator="," close=")"> #{id} </foreach> </select>
2 list
<select id="queryPojoById" parameterType="list" resultMap="pojo">
select * from t_table where id in
<foreach collection="list" index="index" item="id" open="(" separator="," close=")">
#{id}
</foreach>
</select>
3 Map
<select id="queryPojoById" parameterType="map" resultMap="pojo">
select * from t_table where id in
<foreach collection="ids" index="index" item="id" open="(" separator="," close=")">
#{id}
</foreach>
</select>
这里的ids指的的是你放入map里面的key
