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

1.首先通过sql查询找到我们需要的页面，从其中的template字段复制出原视图的配置 通过模型编码model在base_view查找需要修改的视图 select * from base_view where model='workflow.WorkflowUserTask' and is_deleted = 0; 2.将base_view的template内容复制到java的core工程的resources目录下新建一个xml文件，修改里面的动作名称 <view widget="WorkFlowImplement"> <template slot="actions"> <action name="$$internal_GotoListTableRouter" priority="1" model="workflow.WorkflowUserTask" tag="contextFreeAction"/> <action name="approveStaging" widget="FlowTaskCommonAction" invisible="!(activeRecord.allowStaging)" priority="2" label="新暂存" model="workflow.WorkflowUserTask" displayName="新暂存"/> <action name="workflow_agree" invisible="!(activeRecord.allowAgree && activeRecord.status == 'ACTIVE')" priority="3" label="新同意" model="workflow.WorkflowUserTask" load="fetchDetailReadOnly" displayName="新同意" goBack="true" validateForm="true" loadRootData="true"/> <action name="workflow_rejust" invisible="!(activeRecord.allowReject && activeRecord.status == 'ACTIVE')" priority="4" label="新拒绝" model="workflow.WorkflowUserTask" displayName="新拒绝" goBack="true" loadRootData="true" tag="contextFreeAction"/> <action name="workflow_turnon" invisible="!(activeRecord.taskType == 'APPROVE' && activeRecord.allowTransfer && activeRecord.status == 'ACTIVE')" priority="5" label="新转交" model="workflow.WorkflowUserTask" load="fetchDetailReadOnly" displayName="新转交" goBack="true" loadRootData="true" tag="contextFreeAction"/> <action name="workflow_addsign" invisible="!(activeRecord.taskType == 'APPROVE' && activeRecord.allowAddSign && activeRecord.status == 'ACTIVE')" priority="6" label="新加签" model="workflow.WorkflowUserTask" load="fetchDetailReadOnly" displayName="新加签" goBack="true" loadRootData="true" tag="contextFreeAction"/> <action name="workflow_write_fallback" invisible="!(activeRecord.taskType == 'WRITE' && activeRecord.allowFallback && activeRecord.status == 'ACTIVE')" priority="7" label="新回退" model="workflow.WorkflowUserTask" displayName="新回退" goBack="true" loadRootData="true" tag="contextFreeAction"/> <action name="workflow_sharing" priority="8" label="新分享" model="workflow.WorkflowUserTask" displayName="新分享" goBack="true" loadRootData="true" tag="contextFreeAction"/> </template> <template slot="fields"> <field name="remark" widget="TextArea" invisible="activeRecord.taskType != 'APPROVE'" priority="8" model="workflow.WorkflowUserTask" data="remark" displayName="意见备注"/> </template> </view> 3.在生命周期的元数据编辑方法内覆盖视图 package pro.shushi.pamirs.demo.core.init; import org.springframework.core.Ordered; import org.springframework.core.annotation.Order; import org.springframework.stereotype.Component; import pro.shushi.pamirs.boot.common.api.command.AppLifecycleCommand; import pro.shushi.pamirs.boot.common.extend.MetaDataEditor; import pro.shushi.pamirs.core.common.InitializationUtil; import pro.shushi.pamirs.demo.api.DemoModule; import pro.shushi.pamirs.meta.annotation.fun.extern.Slf4j; import pro.shushi.pamirs.meta.api.dto.meta.Meta; import pro.shushi.pamirs.meta.enmu.ViewTypeEnum; import pro.shushi.pamirs.workflow.app.api.model.WorkflowUserTask; import java.util.Map; @Slf4j @Component @Order(Ordered.LOWEST_PRECEDENCE) public class DemoModuleMetaInstall implements MetaDataEditor { @Override public void edit(AppLifecycleCommand command,…
总体介绍 Oinone的分库分表方案是基于Sharding-JDBC的整合方案，要先具备一些Sharding-JDBC的知识。[Sharding-JDBC]https://shardingsphere.apache.org/document/current/cn/overview/ 做分库分表前，大家要有一个明确注意的点就是分表字段（也叫均衡字段）的选择，它是非常重要的，与业务场景非常相关。在明确了分库分表字段以后，甚至在功能上都要做一些妥协。比如分库分表字段在查询管理中做为查询条件是必须带上的，不然效率只会更低。 分表字段不允许更新，所以代码里更新策略设置类永不更新，并在设置了在页面修改的时候为readonly 配置分表策略 配置ShardingModel模型走分库分表的数据源pamirsSharding 为pamirsSharding配置数据源以及sharding规则 a. pamirs.sharding.define用于oinone的数据库表创建用 b. pamirs.sharding.rule用于分表规则配置 为pamirsSharding配置数据源以及sharding规则 1）指定模型对应数据源 pamirs: framework: system: system-ds-key: base system-models: – base.WorkerNode data: default-ds-key: pamirs ds-map: base: base modelDsMap: "[demo.ShardingModel]": pamirsSharding #配置模型对应的库 2）分库分表规则配置 pamirs: sharding: define: data-sources: ds: pamirs pamirsSharding: pamirs #申明pamirsSharding库对应的pamirs数据源 models: "[trigger.PamirsSchedule]": tables: 0..13 "[demo.ShardingModel]": tables: 0..7 table-separator: _ rule: pamirsSharding: #配置pamirsSharding库的分库分表规则 actual-ds: – pamirs #申明pamirsSharding库对应的pamirs数据源 sharding-rules: # Configure sharding rule ，以下配置跟sharding-jdbc配置一致 – tables: demo_core_sharding_model: #demo_core_sharding_model表规则配置 actualDataNodes: pamirs.demo_core_sharding_model_${0..7} tableStrategy: standard: shardingColumn: user_id shardingAlgorithmName: table_inline shardingAlgorithms: table_inline: type: INLINE props: algorithm-expression: demo_core_sharding_model_${(Long.valueOf(user_id) % 8)} props: sql.show: true 自定义规则 默认规则即通用的分库分表策略，如按照数据量、哈希等方式进行分库分表；通常默认规则是可以的。 但在一些复杂的业务场景下，使用默认规则可能无法满足需求，需要根据实际情况进行自定义。例如，某些业务可能有特定的数据分布模式或者查询特点，需要定制化的分库分表规则来优化数据访问性能或者满足业务需求。在这种情况下，使用自定义规则可以更好地适应业务的需求。 自定义分表规则示例 示例1：按月份分表（DATE_MONTH ） package pro.shushi.pamirs.demo.core.sharding; import cn.hutool.core.date.DateUtil; import com.google.common.collect.Range; import org.apache.shardingsphere.sharding.api.sharding.standard.PreciseShardingValue; import org.apache.shardingsphere.sharding.api.sharding.standard.RangeShardingValue; import org.apache.shardingsphere.sharding.api.sharding.standard.StandardShardingAlgorithm; import org.springframework.stereotype.Component; import pro.shushi.pamirs.meta.annotation.fun.extern.Slf4j; import java.util.*; /** * @author wangxian * @version 1.0 * @description */ @Component @Slf4j public class DateMonthShardingAlgorithm implements StandardShardingAlgorithm<Date> { private Properties props; @Override public String doSharding(Collection<String> availableTargetNames, PreciseShardingValue<Date> preciseShardingValue) { Date date = preciseShardingValue.getValue(); String suffix = "_" + (DateUtil.month(date) + 1); for (String tableName : availableTargetNames) { if (tableName.endsWith(suffix)) { return tableName; } } throw new IllegalArgumentException("未找到匹配的数据表"); } @Override public Collection<String> doSharding(Collection<String> availableTargetNames, RangeShardingValue<Date> rangeShardingValue) { List<String> list =…
有些业务场景需要查询两张表的数据，这时候就需要用到联表查询。下面将介绍两种方式进行联表查询。 场景：A模型页面，查询条件中包含B模型字段 模型A @Model.model(YesOne.MODEL_MODEL) @Model(displayName = "YesOne", summary = "YesOne") public class YesOne extends IdModel { public static final String MODEL_MODEL = "top.YesOne"; @Field.Integer @Field(displayName = "YesId") private Long yesId; @Field.String @Field(displayName = "名字") private String name; @Field.String @Field(displayName = "科目名字") private String professionalName; @Field(displayName = "关联YesTwo") @Field.many2one @Field.Relation(relationFields = {"yesId"},referenceFields = {"id"}) private YesTwo yesTwo; } 模型B @Model.model(YesTwo.MODEL_MODEL) @Model(displayName = "YesTwo", summary = "YesTwo") public class YesTwo extends IdModel { public static final String MODEL_MODEL = "top.YesTwo"; @Field.Integer @Field(displayName = "科目id") private Long professionalId; @Field.String @Field(displayName = "科目名字") private String professionalName; } 1. 使用in的方式查询 通过B模型的查询条件查询出符合条件的所有数据ID，再根据这个ID去A模型里面查询出所需的数据。 @Function.Advanced(displayName = "查询列表", type = FunctionTypeEnum.QUERY, category = FunctionCategoryEnum.QUERY_PAGE, managed = true) @Function(openLevel = {FunctionOpenEnum.LOCAL, FunctionOpenEnum.REMOTE, FunctionOpenEnum.API}) public Pagination<YesOne> queryPage(Pagination<YesOne> page, IWrapper<YesOne> queryWrapper) { String professionalName = (String) queryWrapper.getQueryData().get("professionalName"); if (StringUtils.isNotBlank(professionalName)) { List<Long> yesTwoId = new YesTwo().queryList(Pops.<YesTwo>lambdaQuery() .from(YesTwo.MODEL_MODEL) .eq(YesTwo::getProfessionalName, professionalName)) .stream().map(YesTwo::getId) .collect(Collectors.toList()); LambdaQueryWrapper<YesOne> wq = Pops.<YesOne>lambdaQuery().from(YesOne.MODEL_MODEL); if (CollectionUtils.isNotEmpty(yesTwoId)) { wq.in(YesOne::getYesId, yesTwoId); } return new YesOne().queryPage(page, wq); } return new YesOne().queryPage(page, queryWrapper); } 2. 使用mapper的方式查询 利用sql的方式去直接查询出结果。使用联表查询的方式查询 @Autowired private YesOneQueryMapper yesOneQueryMapper; @Function.Advanced(displayName = "查询列表", type = FunctionTypeEnum.QUERY, category = FunctionCategoryEnum.QUERY_PAGE, managed = true) @Function(openLevel = {FunctionOpenEnum.LOCAL,…
