组装多个update语句，这种方式需要设置jdbc连接 allowMultiQueries=true

    <update id="batchUpdatePushStatusByPrimaryKey" parameterType="java.util.List">
        <foreach collection="list" item="item" separator=";">
            update t_subscribe_info_third_part_detail
            set
            push_status          = #{item.pushStatus,jdbcType=SMALLINT},
            push_count          = #{item.pushCount,jdbcType=INTEGER},
            push_time           = #{item.pushTime,jdbcType=TIMESTAMP}
            where id = #{item.id,jdbcType=BIGINT}
        </foreach>
    </update>

如果没有设置，即使使用了;分隔多个sql语句，执行器也会认为是一条sql语句，会在执行时报错
