proto文件

message DbRecord {
  string table =1;
  repeated string dataColumn =2;
}

java代码中的使用方法：

DbRecord dbRecord = DbRecord.newBuilder().addDataColumn("1").addDataColumn("2")
                    .setTable("a").setDataColumn(0,"88")
                    .setDataColumn(1,"96")
            .build();

System.out.println(dbRecord.getDataColumnCount());
                    System.out.println(dbRecord.getDataColumn(1));
