RocketMQ消费者在macOS中出现类似RemotingTimeoutException: invokeSync call timeout错误处理办法:
- 命令行中执行脚本
scutil --set HostName $(scutil --get LocalHostName)
- 重启应用

1.实现SPI接口 import pro.shushi.pamirs.meta.common.spi.SPI; import pro.shushi.pamirs.meta.common.spi.factory.SpringServiceLoaderFactory; import pro.shushi.pamirs.workflow.app.api.entity.WorkflowContext; import pro.shushi.pamirs.workflow.app.api.model.WorkflowInstance; @SPI(factory = SpringServiceLoaderFactory.class) public interface WorkflowEndNoticeApi { void execute(WorkflowContext context, WorkflowInstance instance); } 自定义通知逻辑 /** * 自定义扩展流程结束时扩展点 */ @Order(999) @Component @SPI.Service public class MyWorkflowEndNoticeApi implements WorkflowEndNoticeApi { @Override public void execute(WorkflowContext context, WorkflowInstance instance) { Long dataBizId = instance.getDataBizId(); //todo自定义逻辑 } }
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
指定字段排序 平台默认排序字段,参考IdModel,按创建时间和ID倒序(ordering = "createDate DESC, id DESC") 方法1:模型指定排序 模型定义增加排序字段。@Model.Advanced(ordering = "xxxxx DESC, yyyy DESC") @Model.model(PetShop.MODEL_MODEL) @Model(displayName = "宠物店铺",summary="宠物店铺",labelFields ={"shopName"}) @Model.Code(sequence = "DATE_ORDERLY_SEQ",prefix = "P",size=6,step=1,initial = 10000,format = "yyyyMMdd") @Model.Advanced(ordering = "createDate DESC") public class PetShop extends AbstractDemoIdModel { public static final String MODEL_MODEL="demo.PetShop"; // ………… } 方法2:Page查询中可以自定排序规则 API参考 pro.shushi.pamirs.meta.api.dto.condition.Pagination#orderBy public <G, R> Pagination<T> orderBy(SortDirectionEnum direction, Getter<G, R> getter) { if (null == getSort()) { setSort(new Sort()); } getSort().addOrder(direction, getter); return this; } 具体示例 @Function.Advanced(type= FunctionTypeEnum.QUERY) @Function.fun(FunctionConstants.queryPage) @Function(openLevel = {FunctionOpenEnum.API}) public Pagination<PetShop> queryPage(Pagination<PetShop> page, IWrapper<PetShop> queryWrapper){ page.orderBy(SortDirectionEnum.DESC, PetShop::getCreateDate); page = new PetShop().queryPage(page, queryWrapper); return page; } 方法3:查询的wapper中指定 API参考:pro.shushi.pamirs.framework.connectors.data.sql.AbstractWrapper#orderBy @Override public Children orderBy(boolean condition, boolean isAsc, R… columns) { if (ArrayUtils.isEmpty(columns)) { return typedThis; } SqlKeyword mode = isAsc ? ASC : DESC; for (R column : columns) { doIt(condition, ORDER_BY, columnToString(column), mode); } return typedThis; } 具体示例 public List<PetShop> queryList(String name) { List<PetShop> petShops = Models.origin().queryListByWrapper( Pops.<PetShop>lambdaQuery().from(PetShop.MODEL_MODEL) .orderBy(true, true, PetShop::getCreateDate) .orderBy(true, true, PetShop::getId) .like(PetShop::getShopName, name)); return petShops; } 设置查询不排序 方法1:关闭平台默认排序字段,设置模型的ordering,改成:ordering = "1=1" 模型定义增加排序字段。@Model.Advanced(ordering = "1=1") @Model.model(PetShop.MODEL_MODEL) @Model(displayName = "宠物店铺",summary="宠物店铺",labelFields ={"shopName"}) @Model.Code(sequence = "DATE_ORDERLY_SEQ",prefix = "P",size=6,step=1,initial = 10000,format = "yyyyMMdd") @Model.Advanced(ordering =…
