sqltoy推荐大家项目按照业务划分先分模块(消息中心、系统管理、订单管理等)后分层(web层、service)，sql文件放于模块中便于模块整体迁移和产品化 -* 有利于开发过程，一般项目按模块分工，让开发者不需要不断的切换目录 -* 当然这个是sqltoy推荐做法，开发者则可以根据自身实际情况而定,并非强制! - -## 为什么缓存不用redis? -* 这里的缓存主要用于频繁的结果字段翻译，一旦你用了缓存翻译后你就会发现会在极为广泛的范围内使用，只有本地内存级缓存才能经得起频繁任意反复的调用，没有必要再来一个redis的IO消耗 -* 你可以通过扩展实现ehcache+redis模式，来提升缓存的刷新实时性,但代价比较大造成了项目的复杂性,sqltoy提供的增量更新模式基本可以控制秒级更新 - -## 为什么quickvo任务不是一个，而是按模块分多个任务 -* sqltoy强调项目模块化，便于开发提炼出相对产品化的功能模块，逐步减少每次项目重复性工作，让不通过业务代码集中于一个模块下便于模块成熟后的抽离 - -## 如何分VO和POJO -* 请参见sqltoy-strict项目 https://github.com/sagframe/sqltoy-strict - -## 如何分库分表 -* 在本项目里面已经演示了分表 -* 分库分表含事务型的范例: https://github.com/sagframe/sqltoy-showcase/tree/master/trunk/sqltoy-sharding - -## 为什么dao不采用mybatis plus的接口模式？ -* mybatis dao采用接口模式，是其向jpa方向靠拢的一种模式，而sqltoy本身就是jpa+查询模式，也就是说jpa向查询方向加强，正好相反！ -* 什么接口?能够用接口来完成就是意味着可以用一个通用方法来代替！因此接口式dao的存在必要性就值得商榷！ - -```java -@Service("organInfoService") -public class OrganInfoServiceImpl implements OrganInfoService { - //sqltoyLazyDao 就可以代替接口式的dao - @Autowired - SqlToyLazyDao sqlToyLazyDao; - - @Transactional - public void saveOrganInfo(OrganInfoVO organInfoVO) { - // 先保存机构 - sqlToyLazyDao.saveOrUpdate(organInfoVO); - // 设置树形表的节点路径等字段值,便于统一树形查询 - // id字段根据vo找表的主键会自动匹配上,其它的NODE_ROUTE\NODE_LEVEL\IS_LEAF 为标准命名无需额外设置 - //idField 如果是主键则无需设置 - sqlToyLazyDao.wrapTreeTableRoute(new TreeTableModel(organInfoVO).pidField("organPid")); - } -} - -``` -* 考虑一些场景下dao仍然要做一些数据的封装处理(简化service层，将service尽量体现业务逻辑，减少一些dao的数据组装干扰)，sqltoy仍然可以写dao，但dao时实体类！ - -如下：实体类又有何不妥呢！清晰又可以针对一些特殊情况自己完善一些小处理，mybatis那种接口通过aop方式谈不上什么酷和高技术，不要被带到沟里去了，清晰、可维护、好拓展才是正道! - -```java -@Repository("staffInfoDao") -public class StaffInfoDao extends SqlToyDaoSupport { - /** - * @TODO 提供一个分页并动态设置缓存翻译的演示 - * @param pageModel - * @param staffInfoVO - * @return - */ - public PaginationModel findStaff(PaginationModel pageModel, StaffInfoVO staffInfoVO) { - // sql可以直接在代码中编写,复杂sql建议在xml中定义 - // 单表entity查询场景下sql字段可以写成java类的属性名称 - // 单表查询一般适用于接口内部查询 - String sql = "#[staffName like :staffName]#[and createTime>=:beginDate]#[and createTime<=:endDate]"; - return findEntity(StaffInfoVO.class, pageModel, EntityQuery.create().where(sql).values(staffInfoVO) - // 字典缓存必须要设置cacheType - // 单表对象查询需设置keyColumn构成select keyColumn as column模式 - .translates(new Translate("dictKeyName").setColumn("sexTypeName").setCacheType("SEX_TYPE") - .setKeyColumn("sexType")) - .translates(new Translate("organIdName").setColumn("organName").setKeyColumn("organId"))); - } -``` - -## 多数据源怎么弄? -* 如果是同类单据根据特定规则分多个库，请参见分库策略进行 -* 通过多个lazyDao模式 - -```java - @Bean(name = "sqlToySkylineDao") - public SqlToyLazyDao sqlToySkylineDao(@Qualifier("dataSourceSkyline") DataSource dataSource){ - SqlToyLazyDaoImpl dao = new SqlToyLazyDaoImpl(); - dao.setDataSource(dataSource); - return dao; - } - - @Bean(name = "sqlToyLazyDao") - public SqlToyLazyDao sqlToyLazyDao(@Qualifier("dataSource") DataSource dataSource) { - SqlToyLazyDaoImpl dao = new SqlToyLazyDaoImpl(); - dao.setDataSource(dataSource); - return dao; + /** + * 查询其他数据源 + */ + @Test + public void changeDatabaseQuery() { + dynamicService.changeDatabaseQuery(); } -``` -* 通过lazyDao里面调用时指定dataSource,save、update、load等都有链式操作 - -```java -sqlToyLazyDao.save().dataSource(dataSource).saveMode(SaveMode.IGNORE).many(entities); -sqlToyLazyDao.query().sql("qstart_fastPage").dataSource(dataSource).entity(staffVO).findPage(pageModel); -``` - -## 我想通过包路径来实现不同数据库访问 -* 请扩展实现org.sagacity.sqltoy.plugins.datasource.ObtainDataSource 接口 -* 当前默认实现(你可以通过aop+ThreadLocal来修改实现) - -```java -public class DefaultObtainDataSource implements ObtainDataSource { - /** - * 定义日志 - */ - protected final Logger logger = LoggerFactory.getLogger(DefaultObtainDataSource.class); - - private DataSource dataSource; - - @Override - public DataSource getDataSource(ApplicationContext applicationContext, DataSource defaultDataSource) { - // 避免每次去查找(适用于固定数据源场景) - if (this.dataSource != null) { - return this.dataSource; - } - Map result = applicationContext.getBeansOfType(DataSource.class); - // 只有一个dataSource,直接使用 - if (result.size() == 1) { - this.dataSource = result.values().iterator().next(); - } - // 非单一数据源,通过sqltoyContext中定义的默认dataSource来获取 - if (this.dataSource == null) { - this.dataSource = defaultDataSource; - } - // 理论上应该先获取primary的数据源,目前不知道如何获取 - // 多数据源情况下没有指定默认dataSource则返回名称为dataSource的数据源 - if (this.dataSource == null && applicationContext.containsBean("dataSource")) { - this.dataSource = (DataSource) applicationContext.getBean("dataSource"); - } - if (this.dataSource == null) { - logger.error("在多数据源场景下,请为dao正确指定dataSource,或配置spring.sqltoy.defaultDataSource=默认数据源名称!"); - } - return this.dataSource; - } -} -``` -## sqltoy传参支持map吗？ -* sqltoy传参可以三种 - -```java /** - * @todo 通过对象传参数,简化paramName[],paramValue[] 模式传参 - * @param - * @param sqlOrNamedSql 可以是具体sql也可以是对应xml中的sqlId - * @param entity 通过对象传参数,并按对象类型返回结果 - * @return - */ -
