Salmon

Salmon , an easy framework which support distributed db system.

自研可控的分布式数据库框架

• 简化dao层开发，比mybatis更可控更灵活
• 支持常规事务、基于二阶段协议提交以及重试机制的跨库事务
• 支持多种策略分库分表
• 支持jdbc、oracle等主流数据库
• 无缝对接spring

查询

@Autowired
@Mapper(file = "mapper1", database = DataBase.JDBC)
public Salmon salmon;

//查询
Map map = (Map) salmon.select("query2").execute("101a7cb6-0aff-11ec-b26b-88e9fe840b9a");

//查询
Map map = (Map) salmon.select("query").execute(Collections.singletonMap("id", "101a7cb6-0aff-11ec-b26b-88e9fe840b9a"));

插入

// 插入
Map param3 = Maps.newConcurrentMap();
param3.put("id", UUID.randomUUID().toString());
param3.put("namespace", "test");
param3.put("path", "spring.port");
param3.put("value", "9093");
salmon.insert("insert").execute(param);

事务

//开启事务

salmon.startTrans();
Map param = Maps.newConcurrentMap();
param.put("id", UUID.randomUUID().toString());
param.put("namespace", "test");
param.put("path", "spring.port");
param.put("value", "9091");
salmon.insertTrans("insert").execute(param);

Map param2 = Maps.newConcurrentMap();
param2.put("id", UUID.randomUUID().toString());
param2.put("namespace", "test");
param2.put("path", "spring.port");
param2.put("value", "9092");
salmon.insertTrans("insert").execute(param2);

salmon.commitTrans();
