在 oinone 平台中，提供了默认的左树右表的视图，用户可以通过界面设计器配置，默认的树视图不一定满足所有需求，尤其当需要自定义功能或复杂的交互时，我们可以通过自定义视图来实现更灵活的展现。 本文将带你一步步了解如何自定义左树右表视图中的树组件。 自定义树视图 1. 使用界面设计器配置视图 首先，我们需要通过界面设计器生成基础的左树右表视图。界面设计器允许用户根据不同需求进行拖拽配置，快速创建可视化界面。 配置完视图之后，我们可以重写左侧的树组件。Oinone 的默认树组件是 TableSearchTreeWidget，通过自定义的方式，我们可以实现更高级的功能。 2. 重写 TableSearchTreeWidget import { BaseElementWidget, SPI, TableSearchTreeWidget, ViewType } from '@kunlun/dependencies'; import CustomTableSearchTree from './CustomTableSearchTree.vue'; @SPI.ClassFactory( BaseElementWidget.Token({ viewType: [ViewType.Table, ViewType.Form], widget: 'tree', model: 'resource.k2.Model0000000100' // 改成自己的模型 }) ) export class CustomTableSearchTreeWidget extends TableSearchTreeWidget { public initialize(props) { super.initialize(props); this.setComponent(CustomTableSearchTree); return this; } } 3. 定义 Vue 树组件 接下来，我们来实现 CustomTableSearchTree.vue 组件。这个组件将处理树的数据加载、节点选中等逻辑。你可以根据项目的需要修改其中的交互逻辑或 UI 设计。 <template> <a-tree :load-data="onLoadData" :tree-data="treeData" @select="onSelected" /> </template> <script lang="ts"> import { OioTreeNode, TreeUtils } from '@kunlun/dependencies'; import { computed, defineComponent } from 'vue'; export default defineComponent({ props: { rootNode: { type: Object }, loadData: { type: Function, required: true }, onSelected: { type: Function, required: true } }, setup(props) { // // 计算树的数据源，使用 TreeUtils 处理 const treeData = computed(() => { return TreeUtils.fillLoadMoreAction([…(props.rootNode?.children || [])]); }); // 异步加载子节点 const onLoadData = async (node) => { return await props.loadData(node.dataRef); }; // 处理节点选中事件 const onSelected = ( selectedKeys: string[], e: { nativeEvent: PointerEvent; node: { dataRef: OioTreeNode }; selected: boolean } ) => { props.onSelected?.(e.node.dataRef, e.selected); }; return { treeData, onLoadData, onSelected }; } }); </script> 4. 自定义…
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;…
场景描述 用户在自定义接口提供给前端调用时 @Action(displayName = "注册", bindingType = ViewTypeEnum.CUSTOM) public BaseResponse register(UserZhgl data) { //…逻辑 return result; } import java.io.Serializable; public class BaseResponse implements Serializable { private String code; private String msg; public BaseResponse() { } public BaseResponse(String code, String msg) { this.code = code; this.msg = msg; } public String getCode() { return code; } public void setCode(String code) { this.code = code; } public String getMsg() { return msg; } public void setMsg(String msg) { this.msg = msg; } } gql执行时出现报错 { "errors":[ { "message":"Validation error of type SubSelectionNotAllowed: Sub selection not allowed on leaf type Object of field register @ 'zhglMutation/register'", "locations":[ { "line":3, "column":3 } ], "extensions":{ "classification":"ValidationError" } } ] } 解决方案 1.返回对象不为空时，对象必须是模型，否则无法解析返回参数2.前端调用GQL异常时，可以用Insomnia工具对GQL进行测试，根据错误提示对GQL进行修改和排查3.GQL正常情况下，执行以后可根据后端日志进行错误排查

总体介绍 Oinone的读写分离方案是基于Sharding-JDBC的整合方案，要先具备一些Sharding-JDBC的知识。 [Sharding-JDBC] 读写分离依赖于主从复制来同步数据，从库复制数据后，才能通过读写分离策略将读请求分发到从库，实现读写操作的分流，请根据业务需求自行实现主从配置。 配置读写策略 配置 top_demo 模块走读写分离的逻辑数据源 pamirsSharding。 配置数据源。 为 pamirsSharding 配置数据源以及 sharding 规则。 指定需要被sharding-jdbc接管的模块 指定top_demo模块给 Sharding-JDBC 接管，接管逻辑数据源名为 pamirsSharding pamirs: framework: data: ds-map: base: base top_demo: pamirsSharding 配置数据源 pamirs: datasource: pamirsMaster: driverClassName: com.mysql.cj.jdbc.Driver type: com.alibaba.druid.pool.DruidDataSource url: jdbc:mysql://127.0.0.1:3306/61_pamirs_mydemo_master?useSSL=false&allowPublicKeyRetrieval=true&useServerPrepStmts=true&cachePrepStmts=true&useUnicode=true&characterEncoding=utf8&serverTimezone=Asia/Shanghai&autoReconnect=true&allowMultiQueries=true username: root password: ma123456 initialSize: 5 maxActive: 200 minIdle: 5 maxWait: 60000 timeBetweenEvictionRunsMillis: 60000 testWhileIdle: true testOnBorrow: false testOnReturn: false poolPreparedStatements: true asyncInit: true pamirsSlaver: # 从库数据源配置 driverClassName: com.mysql.cj.jdbc.Driver type: com.alibaba.druid.pool.DruidDataSource url: jdbc:mysql://127.0.0.1:3306/61_pamirs_mydemo_slaver?useSSL=false&allowPublicKeyRetrieval=true&useServerPrepStmts=true&cachePrepStmts=true&useUnicode=true&characterEncoding=utf8&serverTimezone=Asia/Shanghai&autoReconnect=true&allowMultiQueries=true username: root password: ma123456 initialSize: 5 maxActive: 200 minIdle: 5 maxWait: 60000 timeBetweenEvictionRunsMillis: 60000 testWhileIdle: true testOnBorrow: false testOnReturn: false poolPreparedStatements: true asyncInit: true 配置读写数据源及规则 pamirs: sharding: define: data-sources: pamirsSharding: pamirsMaster # 为逻辑数据源pamirsSharding指向主数据源pamirsMaster。 models: "[trigger.PamirsSchedule]": tables: 0..13 rule: pamirsSharding: actual-ds: # 指定逻辑数据源pamirsSharding代理的数据源为pamirsMaster、pamirsSlaver – pamirsMaster – pamirsSlaver # 以下配置跟sharding-jdbc配置一致 replicaQueryRules: – data-sources: pamirsSharding: primaryDataSourceName: pamirsMaster # 写库数据源 replicaDataSourceNames: – pamirsSlaver # 读库数据源 loadBalancerName: round_robin load-balancers: round_robin: type: ROUND_ROBIN # 读写规则
