环境运行时Jar版本控制
为了避免基于低代码定义产生的元数据错乱。因此产生了运行时Jar版本检查功能。
如果当前运行时依赖的Ja版本低于已安装版本，启动时会有如下类似信息提示：
依赖Jar版本-PgoBack=true 强制覆盖安装当前运行时版本
java -jar 方式
java -jar xxx.jar -PgoBack=true [其他参数]mvn spring-boot run 方式
mvn clean compile spring-boot:run -Dspring-boot.run.arguments="-PgoBack=true [其他参数]"Oinone社区 作者：yakir原创文章，如若转载，请注明出处：https://doc.oinone.top/backend/20619.html

场景描述 在碰到大数据量并且需要全文检索的场景，我们在分布式架构中基本会架设ElasticSearch来作为一个常规解决方案。在oinone体系中增强模型就是应对这类场景，其背后也是整合了ElasticSearch; 使用前你应该 了解ElasticSearch，包括不限于：Index(索引)、分词、Node(节点)、Document(文档)、Shards(分片) & Replicas(副本)。参考官方网站：https://www.elastic.co/cn/ 有一个可用的ElasticSearch环境(本地项目能引用到) 前置约束 增强模型增量依赖数据变更实时消息，因此确保项目的event是开启的，mq配置正确。 项目引入搜索步骤 1、boot工程加入相关依赖包 boot工程需要指定ES客户端包版本，不指定版本会隐性依赖顶层spring-boot依赖管理指定的低版本 boot工程加入pamris-channel的工程依赖 <dependency> <groupId>org.elasticsearch.client</groupId> <artifactId>elasticsearch-rest-client</artifactId> <version>8.4.1</version> </dependency> <dependency> <groupId>jakarta.json</groupId> <artifactId>jakarta.json-api</artifactId> <version>2.1.1</version> </dependency> <dependency> <groupId>pro.shushi.pamirs.core</groupId> <artifactId>pamirs-sql-record-core</artifactId> </dependency> <dependency> <groupId>pro.shushi.pamirs.core</groupId> <artifactId>pamirs-channel-core</artifactId> </dependency> 2、api工程加入相关依赖包 在XXX-api中增加入pamirs-channel-api的依赖 <dependency> <groupId>pro.shushi.pamirs.core</groupId> <artifactId>pamirs-channel-api</artifactId> </dependency> 3、yml文件配置 在pamirs-demo-boot的application-dev.yml文件中增加配置pamirs.boot.modules增加channel，即在启动模块中增加channel模块。同时注意es的配置，是否跟es的服务一致 pamirs: record: sql: #改成自己本地路径(或服务器路径) store: /Users/oinone/record boot: modules: – channel ## 确保也安装了sql_record – sql_record channel: packages: # 增强模型扫描包配置 – com.xxx.xxx elastic: url: 127.0.0.1:9200 4、项目的模块增加模块依赖 XXXModule增加对ChannelModule的依赖 @Module(dependencies = {ChannelModule.MODULE_MODULE}) 5、增加增强模型(举例) package pro.shushi.pamirs.demo.api.enhance; import pro.shushi.pamirs.channel.enmu.IncrementEnum; import pro.shushi.pamirs.channel.meta.Enhance; import pro.shushi.pamirs.channel.meta.EnhanceModel; import pro.shushi.pamirs.demo.api.model.ShardingModel; import pro.shushi.pamirs.meta.annotation.Model; import pro.shushi.pamirs.meta.enmu.ModelTypeEnum; @Model(displayName = "测试EnhanceModel") @Model.model(ShardingModelEnhance.MODEL_MODEL) @Model.Advanced(type = ModelTypeEnum.PROXY, inherited = {EnhanceModel.MODEL_MODEL}) @Enhance(shards = "3", replicas = "1", reAlias = true,increment= IncrementEnum.OPEN) public class ShardingModelEnhance extends ShardingModel { public static final String MODEL_MODEL="demo.ShardingModelEnhance"; } 6、重启系统看效果 1、进入【传输增强模型】应用，访问增强模型列表我们会发现一条记录，并点击【全量同步】初始化ES，并全量dump数据 2、再次回到Demo应用，进入增强模型页面，可以正常访问并进增删改查操作 个性化dump逻辑 通常dump逻辑是有个性化需求，那么我们可以重写模型的synchronize方法，函数重写特性在“面向对象-继承与多态”部分中已经有详细介绍。 重写ShardingModelEnhance模型的synchronize方法 重写后，如果针对老数据记录需要把新增的字段都自动填充，可以进入【传输增强模型】应用，访问增强模型列表，找到对应的记录并点击【全量同步】 package pro.shushi.pamirs.demo.api.enhance; import pro.shushi.pamirs.channel.enmu.IncrementEnum; import pro.shushi.pamirs.channel.meta.Enhance; import pro.shushi.pamirs.channel.meta.EnhanceModel; import pro.shushi.pamirs.demo.api.model.ShardingModel; import pro.shushi.pamirs.meta.annotation.Field; import pro.shushi.pamirs.meta.annotation.Function; import pro.shushi.pamirs.meta.annotation.Model; import pro.shushi.pamirs.meta.enmu.FunctionTypeEnum; import pro.shushi.pamirs.meta.enmu.ModelTypeEnum; import java.util.List; @Model(displayName = "测试EnhanceModel") @Model.model(ShardingModelEnhance.MODEL_MODEL) @Model.Advanced(type = ModelTypeEnum.PROXY, inherited = {EnhanceModel.MODEL_MODEL}) @Enhance(shards = "3", replicas = "1", reAlias = true,increment= IncrementEnum.OPEN) public class ShardingModelEnhance extends ShardingModel { public static final String MODEL_MODEL="demo.ShardingModelEnhance"; @Field(displayName = "nick") private String nick;…
场景概述 【字段类型之关系与引用】一文中已经描述了各种关系字段的常规写法，还有一些特殊场景如：关系映射中存在常量，或者M2M中间表是大于两个字段构成。 场景描述 1、PetTalent模型增加talentType字段2、PetItem与PetTalent的多对多关系增加talentType（达人类型），3、PetItemRelPetTalent中间表维护petItemId、petTalentId以及talentType，PetDogItem和PetCatItem分别重写petTalents字段，关系中增加常量描述。示意图如下： 实际操作步骤 Step1 新增 TalentTypeEnum package pro.shushi.pamirs.demo.api.enumeration; import pro.shushi.pamirs.meta.annotation.Dict; import pro.shushi.pamirs.meta.common.enmu.BaseEnum; @Dict(dictionary = TalentTypeEnum.DICTIONARY,displayName = "达人类型") public class TalentTypeEnum extends BaseEnum<TalentTypeEnum,Integer> { public static final String DICTIONARY ="demo.TalentTypeEnum"; public final static TalentTypeEnum DOG =create("DOG",1,"狗达人","狗达人"); public final static TalentTypeEnum CAT =create("CAT",2,"猫达人","猫达人"); } Step2 PetTalent模型增加talentType字段 package pro.shushi.pamirs.demo.api.model; import pro.shushi.pamirs.demo.api.enumeration.TalentTypeEnum; import pro.shushi.pamirs.meta.annotation.Field; import pro.shushi.pamirs.meta.annotation.Model; @Model.model(PetTalent.MODEL_MODEL) @Model(displayName = "宠物达人",summary="宠物达人",labelFields ={"name"}) public class PetTalent extends AbstractDemoIdModel{ public static final String MODEL_MODEL="demo.PetTalent"; @Field(displayName = "达人") private String name; @Field(displayName = "达人类型") private TalentTypeEnum talentType; } Step3 修改PetItem的petTalents字段，在关系描述中增加talentType（达人类型） @Field.many2many(relationFields = {"petItemId"},referenceFields = {"petTalentId","talentType"},through = PetItemRelPetTalent.MODEL_MODEL ) @Field.Relation(relationFields = {"id"}, referenceFields = {"id","talentType"}) @Field(displayName = "推荐达人",summary = "推荐该商品的达人们") private List<PetTalent> petTalents; Step4 PetDogItem增加petTalents字段，重写父类PetItem的关系描述 talentType配置为常量，填入枚举的值 增加domain描述用户页面选择的时候自动过滤出特定类型的达人，RSQL用枚举的name @Field(displayName = "推荐达人") @Field.many2many( through = "PetItemRelPetTalent", relationFields = {"petItemId"}, referenceFields = {"petTalentId","talentType"} ) @Field.Relation(relationFields = {"id"}, referenceFields = {"id", "#1#"}, domain = " talentType == DOG") private List<PetTalent> petTalents; Step5 PetCatItem增加petTalents字段，重写父类PetItem的关系描述 talentType配置为常量，填入枚举的值 增加domain描述用户页面选择的时候自动过滤出特定类型的达人，RSQL用枚举的name @Field(displayName = "推荐达人") @Field.many2many( through = "PetItemRelPetTalent", relationFields = {"petItemId"}, referenceFields = {"petTalentId","talentType"} ) @Field.Relation(relationFields = {"id"}, referenceFields = {"id", "#2#"}, domain = " talentType == CAT") private List<PetTalent> petTalents; Step6 PetCatItem增加petTalents字段，many2one关系示例 talentType配置为常量，填入枚举的值 增加domain描述用户页面选择的时候自动过滤出特定类型的达人，RSQL用枚举的name @Model.model(PetPet.MODEL_MODEL) @Model(displayName…
