注意:链式调用不可以太长,如果太长可以使用参数接一下,否则在编译时可能会导致栈溢出。

  • Nacos做为注册中心:如何调用其他系统的SpringCloud服务?

    Oinone项目引入Nacos作为注册中心,调用外部的SpringCloud服务 Nacos可以做为注册中心,提供给Dubbo和SpringCloud等微服务框架使用。 目前Oinone的底层使用的是Dubbo进行微服务的默认协议调用,但是我们项目如果存在需要调用其他系统提供的SpringCloud服务,Oinone其实并没有限制大家去这么写代码。 可以参考Nacos或SpringCloud的官方文档,只要不存在Jar包冲突等场景,很多的扩展其实大家都可以使用。 注意!!!Nacos、SpringCloud、SpringCloudAlibaba是有依赖版本严格要求的:点击查看 具体示例: 一、项目中增加依赖 主pom引入兼容的版本: <dependencyManagement> <dependency> <groupId>com.alibaba.cloud</groupId> <artifactId>spring-cloud-alibaba-dependencies</artifactId> <version>2.2.7.RELEASE</version> <!– 目前兼容的版本 –> <type>pom</type> <scope>import</scope> </dependency> </dependencyManagement> 使用模块的pom引入依赖: <dependency> <groupId>com.alibaba.cloud</groupId> <artifactId>spring-cloud-starter-alibaba-nacos-discovery</artifactId> </dependency> <dependency> <groupId>org.springframework.cloud</groupId> <artifactId>spring-cloud-starter-openfeign</artifactId> </dependency> 二、 配置 application.yml spring: cloud: nacos: discovery: server-addr: localhost:8848 username: nacos password: nacos 三、启动类添加注解 @EnableDiscoveryClient @EnableFeignClients public class NacosConsumerApplication { public static void main(String[] args) { SpringApplication.run(NacosConsumerApplication.class, args); } } 四、验证 创建 Feign Client 接口 import org.springframework.cloud.openfeign.FeignClient; import org.springframework.web.bind.annotation.GetMapping; @FeignClient(name = "nacos-demo") // 指定目标服务的名称 public interface ProviderClient { @GetMapping("/hello") String hello(); } 创建 Controller 调用 Feign Client @RestController public class ConsumerController { private final ProviderClient providerClient; public ConsumerController(ProviderClient providerClient) { this.providerClient = providerClient; } @GetMapping("/hello") public String hello() { return providerClient.hello(); } } 在浏览器中访问 http://localhost:8082/hello你应该会看到服务提供者返回的响应。

  • 集成设计器数据流程、流程设计器可以暴露接口触发

    集成设计器数据流程暴露接口触发 需求:在集成设计器配置的连接器、数据流程链接到外部接口,需要可以有一个管理页面,统一管理这些集成配置。比如对接多个医院的挂号系统,希望可以配置好数据流程之后,能够在已经实现的开放接口上,动态的调用集成平台配置的数据流程。 连接器暴露接口触发 设计连接器资源配置模型。使用业务ID+接口唯一标识+连接器实现连接器资源和业务唯一。 @Model.model(EipConnectorResourceSetting.MODEL_MODEL) @Model(displayName = "连接器资源配置", summary = "连接器资源配置") @Model.Advanced(unique = {"hospitalId, interfaceUnique"}) public class EipConnectorResourceSetting extends IdModel { public static final String MODEL_MODEL = "hr.simple.EipConnectorResourceSetting"; @UxTableSearch.FieldWidget(@UxWidget()) @Field(displayName = "医院", required = true) @Field.Relation(relationFields = {"hospitalId"}, referenceFields = {"id"}) private Hospital hospital; @Field.Integer @Field(displayName = "医院ID", invisible = true) private Long hospitalId; @UxTableSearch.FieldWidget(@UxWidget()) @Field.String @Field(displayName = "接口唯一标识", required = true) private String interfaceUnique; @UxTableSearch.FieldWidget(@UxWidget()) @Field.many2one @Field(displayName = "连接器", required = true) @Field.Relation(relationFields = {"connectorId"}, referenceFields = {"id"}) private EipConnector connector; @Field.Integer @Field(displayName = "连接器ID", invisible = true) private Long connectorId; @UxTableSearch.FieldWidget(@UxWidget()) @Field.many2one @Field(displayName = "连接器接口", required = true) @Field.Relation(relationFields = {"integrationInterfaceId"}, referenceFields = {"id"}, domain = "connectorId==${activeRecord.connector.id}") private EipConnectorResource connectorResource; @Field.Integer @Field(displayName = "连接器接口ID", invisible = true) private Long connectorResourceId; } 开放接口定义,文档参考:https://doc.oinone.top/oio4/9326.html外部平台调用开放接口,实现动态调用连接器资源 @Model.model(HospitalSection.MODEL_MODEL) @Model(displayName = "医院科室", summary = "医院科室") public class HospitalSection extends IdModel { public static final String MODEL_MODEL = "net.example.HospitalSection"; @Field(displayName = "科室Code", required = true) private String deptCode; @Field(displayName = "科室名称", required = true) private String deptName; @Field(displayName = "科室描述") private String deptDesc; } @Slf4j @Fun @Component public class TestOpenService { @Resource private TestCommonService testCommonService;…

  • 查询时自定义排序字段和排序规则

    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 ?
