CN Store Server Redis Model

Store Server Redis Model

orm.dart配置

Map orm = {
    'User': {
        'Model': {
            'pk': [0],
            'column': [
                'id',
                'name',
                'email',
                'country',
                'city',
            ],
            'toAddFilter': [],
            'toSetFilter': [0],
            'toFullFilter': [],
            'toAbbFilter': [],
            'toListFilter': [],
        },
        'ModelStore': {
            'storeOrder': [
                {
                    'type': 'redis',
                    'readWriteSeparate': false,
                    'sharding': true,
                    'shardMethod': 'CRC32',
                    'master': 'GameCache',
                    'slave': 'GameCacheSlave',
                    'expire': 86400,
                    'mode': 'Atom',
                    'abb': 'u',
                },
            ],
        },
    },
};

store.dart配置

Map store = {
    'redis': {
        'GameCache': [
            {'no': 0, 'host': 'localhost', 'port': 6379, 'pwd': null, 'db': '0'},
            {'no': 1, 'host': 'localhost', 'port': 6380, 'pwd': null, 'db': '0'},
        ],
        'GameCacheSlave': [
            {'no': 0, 'host': 'localhost', 'port': 6381, 'pwd': null, 'db': '0'},
            {'no': 1, 'host': 'localhost', 'port': 6382, 'pwd': null, 'db': '0'},
        ],
    },
};

使用如下代码进行部署

import 'i_config/deploy.dart';
import 'i_config/orm.dart';
import '../bin/i_maker/lib_i_maker.dart';

void main() {
  IModelMaker modelMaker = new IModelMaker(deploy, orm);
  modelMaker.make();

  IStoreMaker storeMaker = new IStoreMaker(deploy, orm);
  storeMaker.makeServer();

  IUtilMaker utilMaker = new IUtilMaker(deploy);
  utilMaker.make();

  ILibraryMaker libMaker = new ILibraryMaker(deploy);
  libMaker.makeServer();
}

上述代码会在store目录下生成user_rdb_store.dart

使用方法如下：

main.dart

import 'lib_test.dart';

main() {
  // 将User1存入Redis
  User user1 = new User([1, 'ila', 'ila[at]ilaempire.com', 'Japan', 'Tokyo']);

  // 1是user1的id，分Shard时的依据
  UserRedisStore store = new UserRedisStore(1);
  store.add(user1);

  // 上述代码会将user1转换成Redis的命令：
  // hmset u：1 i 1 n ila e ila[at]ilaempire.com c Japan c1 Tokyo
  // expire u：1 86400

  // 从Redis中获取User1
  UserRedisStore store = new UserRedisStore(1);

  // 转换成Redis命令：
  // exists u:1
  // hmget u:1 i n e c c1
  store.get(1)
  .then((User user) {
    print(user.toFull());
    // {"id":1,"name":"ila","email":"ila[at]ilaempire.com","country":"Japan","city":"Tokyo"}
  });
}
