• Schedule相关

  1、Schedule初始化 TODO 2、Schedule执行器的入口 通常本地创建了Schedule，没有被正常执行，可以通过这个入口去排查问题 pro.shushi.pamirs.middleware.schedule.core.tasks.AbstractScheduleTaskDealSingle#selectTasks 3、Schedule执行环境隔离 项目中开发如果本地进行任务调试，通过通过指定ownSign进行环境隔离，如果不配置可能会导致这个任务被别的机器执行，本机的代码无法调试，如果开发的时候出现任务未执行可能是这个原因导致的 event: enabled: true schedule: enabled: true ownSign: dev_wx rocket-mq: namesrv-addr: 127.0.0.1:9876

  如何自定义SQL(Mapper)语句

  场景描述 在实际业务场景中，存在复杂SQL的情况，具体表现为： 单表单SQL满足不了的情况下 有复杂的Join关系或者子查询 复杂SQL的逻辑通过程序逻辑难以实现或实现代价较大 在此情况下，通过原生的mybatis/mybatis-plus, 自定义Mapper的方式实现业务功能 1、编写所需的Mapper SQL Mapper写法无限制，与使用原生的mybaits/mybaits-plus用法一样； Mapper(DAO)和SQL可以写在一个文件中，也分开写在两个文件中。 package pro.shushi.pamirs.demo.core.map; import org.apache.ibatis.annotations.Mapper; import org.apache.ibatis.annotations.Param; import org.apache.ibatis.annotations.Select; import java.util.List; import java.util.Map; @Mapper public interface DemoItemMapper { @Select("<script>select sum(item_price) as itemPrice,sum(inventory_quantity) as inventoryQuantity,categoryId from ${demoItemTable} as core_demo_item ${where} group by category_id</script>") List<Map<String, Object>> groupByCategoryId(@Param("demoItemTable") String pamirsUserTable, @Param("where") String where); } 2.调用mapper 调用Mapper代码示例 package pro.shushi.pamirs.demo.core.map; import com.google.api.client.util.Lists; import org.springframework.stereotype.Component; import pro.shushi.pamirs.demo.api.model.DemoItem; import pro.shushi.pamirs.framework.connectors.data.api.datasource.DsHintApi; import pro.shushi.pamirs.meta.api.core.orm.convert.DataConverter; import pro.shushi.pamirs.meta.api.session.PamirsSession; import pro.shushi.pamirs.meta.common.spring.BeanDefinitionUtils; import java.util.List; import java.util.Map; @Component public class DemoItemDAO { public List<DemoItem> customSqlDemoItem(){ try (DsHintApi dsHint = DsHintApi.model(DemoItem.MODEL_MODEL)) { String demoItemTable = PamirsSession.getContext().getModelCache().get(DemoItem.MODEL_MODEL).getTable(); DemoItemMapper demoItemMapper = BeanDefinitionUtils.getBean(DemoItemMapper.class); String where = " where status = 'ACTIVE'"; List<Map<String, Object>> dataList = demoItemMapper.groupByCategoryId(demoItemTable,where); DataConverter persistenceDataConverter = BeanDefinitionUtils.getBean(DataConverter.class); return persistenceDataConverter.out(DemoItem.MODEL_MODEL, dataList); } return Lists.newArrayList(); } } 调用Mapper一些说明 启动类需要配置扫描包MapperScan @MapperScan(value = "pro.shushi", annotationClass = Mapper.class) @SpringBootApplication(exclude = {DataSourceAutoConfiguration.class, FreeMarkerAutoConfiguration.class}) public class DemoApplication { 调用Mapper接口的时候，需要指定数据源；即上述示例代码中的 DsHintApi dsHint = DsHintApi.model(DemoItem.MODEL_MODEL)， 实际代码中使用 try-with-resources语法。 从Mapper返回的结果中获取数据 如果SQL Mapper中已定义了resultMap，调用Mapper(DAO)返回的就是Java对象 如果Mapper返回的是Map<String, Object>，则通过 DataConverter.out进行转化，参考上面的示例 其他参考：Oinone连接外部数据源方案：https://doc.oinone.top/backend/4562.html

  【PostgreSQL】后端部署使用PostgreSQL数据库

  PostgreSQL数据库配置 驱动配置 Maven配置（14.3版本可用） <postgresql.version>42.6.0</postgresql.version> <dependency> <groupId>org.postgresql</groupId> <artifactId>postgresql</artifactId> <version>${postgresql.version}</version> </dependency> 离线驱动下载 postgresql-42.2.18.jarpostgresql-42.6.0.jarpostgresql-42.7.3.jar JDBC连接配置 pamirs: datasource: base: type: com.alibaba.druid.pool.DruidDataSource driverClassName: org.postgresql.Driver url: jdbc:postgresql://127.0.0.1:5432/pamirs?currentSchema=base username: xxxxxx password: xxxxxx 连接url配置 暂无官方资料 url格式 jdbc:postgresql://${host}:${port}/${database}?currentSchema=${schema} 在jdbc连接配置时，${database}和${schema}必须完整配置，不可缺省。 其他连接参数如需配置，可自行查阅相关资料进行调优。 方言配置 pamirs方言配置 pamirs: dialect: ds: base: type: PostgreSQL version: 14 major-version: 14.3 pamirs: type: PostgreSQL version: 14 major-version: 14.3 数据库版本 type version majorVersion 14.x PostgreSQL 14 14.3 PS：由于方言开发环境为14.3版本，其他类似版本（14.x）原则上不会出现太大差异，如出现其他版本无法正常支持的，可在文档下方留言。 schedule方言配置 pamirs: event: enabled: true schedule: enabled: true dialect: type: PostgreSQL version: 14 major-version: 14.3 type version majorVersion PostgreSQL 14 14.3 PS：由于schedule的方言在多个版本中并无明显差异，目前仅提供一种方言配置。 其他配置 逻辑删除的值配置 pamirs: mapper: global: table-info: logic-delete-value: (EXTRACT(epoch FROM CURRENT_TIMESTAMP) * 1000000 + EXTRACT(MICROSECONDS FROM CURRENT_TIMESTAMP))::bigint PostgreSQL数据库用户初始化及授权 — init root user (user name can be modified by oneself) CREATE USER root WITH PASSWORD 'password'; — if using automatic database and schema creation, this is very important. ALTER USER root CREATEDB; SELECT * FROM pg_roles; — if using postgres database, this authorization is required. GRANT CREATE ON DATABASE postgres TO root;
