批量插入

def test3(param_str)
    log_dir = File.expand_path(File.join(Rails.root.to_s, 'log/nmapresult01_def_v2.log'))
    file = File.open(log_dir)
    file.each_line { |line|
      obj_line = JSON.parse(line)
      if obj_line.count > 0
        puts "obj_line:#{obj_line}"
        # 批量插入
        time = Time.now
        ip = obj_line.first
        obj_line.delete_at(0) #删除数据第一个元素
        Port.bulk_insert(:ip, :port, :created_at, :updated_at) do |ip_port|
          ip_port.set_size = 1000
          obj_line.each do |pt|
            ip_port.add [ip, pt, time, time]
          end
        end
      end
    }
    file.close
