master-slave-sharding's Introduction

#使用JPA+Shardingsphere进行读写分离+分库分表的DEMO

项目支持任意多个套主从(带分表),写主库,查从库

1.设置主从配置

        MasterSlaveRuleConfiguration masterSlaveRuleConfiguration = new MasterSlaveRuleConfiguration("ds", "database0", Arrays.asList("database1"));
        shardingRuleConfig.setMasterSlaveRuleConfigs(Arrays.asList(masterSlaveRuleConfiguration));

2.设置库和表的路由规则

    private TableRuleConfiguration getTableRuleConfiguration() {
        TableRuleConfiguration tableRuleConfiguration = new TableRuleConfiguration(logicTable, actualDataNodes);
        //数据库的选择是用MasterSlaveRuleConfiguration的名称加编号
        tableRuleConfiguration.setDatabaseShardingStrategyConfig(new InlineShardingStrategyConfiguration("goods_type", "ds"));
        tableRuleConfiguration.setTableShardingStrategyConfig(new StandardShardingStrategyConfiguration(shardingColumn, preciseAlgorithm));
        return tableRuleConfiguration;
    }

其它的请下载代码自行查阅

演示:

插入数据,所有数据都写入了主库

http://localhost:8080/save

查询,查询时从库差出来的(可以设置一条只有从库存在的记录来验证)

http://localhost:8080/getone
