  项目中排除掉特定的Hook和扩展点

  总体介绍 在共库共Redis的情况下，某些场景存在需要过滤掉特定Hook和扩展点(extpoint)的情况。本文介绍排除掉的配置方法 1. Oinone如何排除特定的Hook 配置： pamirs: framework: hook: excludes: – 排除的扩展点列表 示例： pamirs: framework: hook: excludes: – pro.shushi.pamirs.timezone.hook.TimezoneHookBefore – pro.shushi.pamirs.timezone.hook.TimezoneHookAfter – pro.shushi.pamirs.timezone.hook.TimezoneSessionInitHook – pro.shushi.pamirs.translate.hook.TranslateAfterHook 2. Oinone如何排除特定的扩展点 配置 pamirs: framework: extpoint: excludes: – 排除的扩展点列表 示例： pamirs: framework: extpoint: excludes: – pro.shushi.pamirs.demo.core.extpoint.PetCatTypeExtPoint

  IWrapper、QueryWrapper和LambdaQueryWrapper使用

  条件更新updateByWrapper 通常我们在更新的时候new一个对象出来在去更新，减少更新的字段 Integer update = new DemoUser().updateByWrapper(new DemoUser().setFirstLogin(Boolean.FALSE), Pops.<DemoUser>lambdaUpdate().from(DemoUser.MODEL_MODEL).eq(IdModel::getId, userId) 使用基础模型的updateById方法更新指定字段的方法： new 一下update对象出来，更新这个对象。 WorkflowUserTask userTaskUp = new WorkflowUserTask(); userTaskUp.setId(userTask.getId()); userTaskUp.setNodeContext(json); userTaskUp.updateById(); 条件删除updateByWrapper public List<T> delete(List<T> data) { List<Long> petTypeIdList = new ArrayList(); for(T item:data){ petTypeIdList.add(item.getId()); } Models.data().deleteByWrapper(Pops.<PetType>lambdaQuery().from(PetType.MODEL_MODEL).in(PetType::getId,petTypeIdList)); return data; } 构造条件查询数据 示例1： LambdaQueryWrapper拼接查询条件 private void queryPetShops() { LambdaQueryWrapper<PetShop> query = Pops.<PetShop>lambdaQuery(); query.from(PetShop.MODEL_MODEL); query.setSortable(Boolean.FALSE); query.orderBy(true, true, PetShop::getId); List<PetShop> petShops2 = new PetShop().queryList(query); System.out.printf(petShops2.size() + ""); } 示例2： IWrapper拼接查询条件 private void queryPetShops() { IWrapper<PetShop> wrapper = Pops.<PetShop>lambdaQuery() .from(PetShop.MODEL_MODEL).eq(PetShop::getId,1L); List<PetShop> petShops4 = new PetShop().queryList(wrapper); System.out.printf(petShops4.size() + ""); } 示例3： QueryWrapper拼接查询条件 private void queryPetShops() { //使用Lambda获取字段名，防止后面改字段名漏改 String nameField = LambdaUtil.fetchFieldName(PetTalent::getName); //使用Lambda获取Clumon名，防止后面改字段名漏改 String nameColumn = PStringUtils.fieldName2Column(nameField); QueryWrapper<PetShop> wrapper2 = new QueryWrapper<PetShop>().from(PetShop.MODEL_MODEL) .eq(nameColumn, "test"); List<PetShop> petShops5 = new PetShop().queryList(wrapper2); System.out.printf(petShops5.size() + ""); } IWrapper转为LambdaQueryWrapper @Function.Advanced(type= FunctionTypeEnum.QUERY) @Function.fun(FunctionConstants.queryPage) @Function(openLevel = {FunctionOpenEnum.API}) public Pagination<PetShopProxy> queryPage(Pagination<PetShopProxy> page, IWrapper<PetShopProxy> queryWrapper) { LambdaQueryWrapper<PetShopProxy> wrapper = ((QueryWrapper<PetShopProxy>) queryWrapper).lambda(); // 非存储字段从QueryData中获取 Map<String, Object> queryData = queryWrapper.getQueryData(); if (null != queryData && !queryData.isEmpty()) { String codes = (String) queryData.get("codes"); if (org.apache.commons.lang3.StringUtils.isNotBlank(codes)) { wrapper.in(PetShopProxy::getCode, codes.split(",")); } } return new PetShopProxy().queryPage(page, wrapper); }

  如何在代码中使用自增ID和获取序列

  在使用继承IDModel或CodeModel时，id和code是系统默认自动生成, 默认值规则：ID–>分布式ID； CODE–>根据定义的SequenceConfig规则自动生成。 在特定情况下需要落库前先生成ID或者Code，这些场景下可参照如下代码示例 一、使用自增ID 单个字段设置方式 // 主键字段，可以使用mysql的自增能力 @Field.Integer @Field.PrimaryKey(keyGenerator = KeyGeneratorEnum.AUTO_INCREMENT) @Field.Advanced(batchStrategy = FieldStrategyEnum.NEVER) @Field(displayName = "id", summary = "Id字段，⾃增") private Long id; @Field.Integer @Field(displayName = "自增版本") @Field.Sequence(sequence = "SEQ", initial = 1) private Long version; 全局设置方式 该方式会作用到每一个存储模型的id字段，在application.yml配置文件中修改id的生成规则，查找配置项关键字key-generator，默认为DISTRIBUTION(分布式id)，可修改为 AUTO_INCREMENT(自增id) 二、手动方式获取序列 获取方式示例1 /** * 在特定场景下需要手动生成Id或者code时，可参照这个示例 */ public void manualSetIdCode(){ DemoItem demoItem = new DemoItem(); //手动生成ID和code Object idObj = Spider.getDefaultExtension(IdGenerator.class).generate(PamirsTableInfo.fetchKeyGenerator(DemoItem.MODEL_MODEL)); demoItem.setId(TypeUtils.createLong(idObj)); Object codeObj = CommonApiFactory.getSequenceGenerator().generate("SEQ",DemoItem.MODEL_MODEL); String code = TypeUtils.stringValueOf(codeObj); demoItem.setCode(code); //…… } 获取方式示例2 1、在系统启动的时候初始化SequenceConfig package pro.shushi.pamirs.demo.core.init; 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.demo.core.constant.SeqConstants; import pro.shushi.pamirs.meta.annotation.fun.extern.Slf4j; import pro.shushi.pamirs.meta.api.dto.meta.Meta; import pro.shushi.pamirs.meta.enmu.SequenceEnum; import java.util.Map; /** * DemoMetadataEditor */ @Slf4j @Component public class DemoMetadataEditor implements MetaDataEditor { @Override public void edit(AppLifecycleCommand command, Map<String, Meta> metaMap) { InitializationUtil util = InitializationUtil.get(metaMap, DemoModule.MODULE_MODULE, DemoModule.MODULE_NAME); if (util == null) { log.error("获取初始化序列失败"); return; } bizSequence(util); } private void bizSequence(InitializationUtil util) { util.createSequenceConfig("申请单编码生成", SeqConstants.NABEL_SAMPLE_APPLY_SEQ, SequenceEnum.ORDERLY_SEQ, 8) .setStep(1) .setInitial(80000000L) .setIsRandomStep(false); util.createSequenceConfig("订单编码生成", SeqConstants.NABEL_SAMPLE_ORDER_SEQ_YP, SequenceEnum.ORDERLY_SEQ, 8) .setPrefix("YP") .setStep(1) .setInitial(80000000L) .setIsRandomStep(false); } } 2、在代码中使用序列 public static String getSaleOrderCode() { Object sequence = CommonApiFactory.getSequenceGenerator().generate(SequenceEnum.ORDERLY_SEQ.value(), SeqConstants.NABEL_SAMPLE_STRUCTURE_SEQ); return TypeUtils.stringValueOf(sequence); } public static String getApplyOrderCode(String prefix) { Object sequence = CommonApiFactory.getSequenceGenerator().generate(SequenceEnum.ORDERLY_SEQ.value(), SeqConstants.NABEL_SAMPLE_APPLY_SEQ); return…
