  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); }

  引入搜索(增强模型Channel)常见问题解决办法

  总体描述 引入Oinone的搜索（即Channel模块）后，因错误的配置、缺少配置或者少引入一些Jar包，会出现一些报错。 问题1：启动报类JCTree找不到 具体现象 启动过程可能会出现报错：java.lang.NoClassDefFoundError: com/sun/tools/javac/tree/JCTree$JCExpression 产生原因 引入Channel模块后，启动过程中会扫描Class包找寻Enhance的注解，Pamirs底层有使用到jdk的tools中的类， com/sun/tools/javac/tree/JCTree$JCExpression 特定版本的jdk可能会缺少tools.jar导致启动失败 具体报错 at org.springframework.boot.loader.Launcher.launch(Launcher.java:107) [pamirs-venus-boot.jar:na] at org.springframework.boot.loader.Launcher.launch(Launcher.java:58) [pamirs-venus-boot.jar:na] at org.springframework.boot.loader.JarLauncher.main(JarLauncher.java:88) [pamirs-venus-boot.jar:na] Caused by: java.util.concurrent.ExecutionException: java.lang.NoClassDefFoundError: com/sun/tools/javac/tree/JCTree$JCExpression at java.util.concurrent.CompletableFuture.reportGet(CompletableFuture.java:357) ~[na:1.8.0_381] at java.util.concurrent.CompletableFuture.get(CompletableFuture.java:1908) ~[na:1.8.0_381] at pro.shushi.pamirs.boot.common.initial.PamirsBootMainInitial.init(PamirsBootMainInitial.java:66) ~[pamirs-boot-api-4.6.10.jar!/:na] at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) ~[na:1.8.0_381] at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:62) ~[na:1.8.0_381] at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) ~[na:1.8.0_381] at java.lang.reflect.Method.invoke(Method.java:498) ~[na:1.8.0_381] at org.springframework.context.event.ApplicationListenerMethodAdapter.doInvoke(ApplicationListenerMethodAdapter.java:305) ~[spring-context-5.2.12.RELEASE.jar!/:5.2.12.RELEASE] … 20 common frames omitted Caused by: java.lang.NoClassDefFoundError: com/sun/tools/javac/tree/JCTree$JCExpression at java.lang.Class.forName0(Native Method) ~[na:1.8.0_381] at java.lang.Class.forName(Class.java:264) ~[na:1.8.0_381] at pro.shushi.pamirs.meta.util.ClassUtils.getClasses(ClassUtils.java:157) ~[pamirs-meta-model-4.6.8.jar!/:na] at pro.shushi.pamirs.meta.util.ClassUtils.getClassesByPacks(ClassUtils.java:73) ~[pamirs-meta-model-4.6.8.jar!/:na] at pro.shushi.pamirs.channel.core.manager.EnhanceModelScanner.enhanceModel(EnhanceModelScanner.java:51) ~[pamirs-channel-core-4.6.15.jar!/:na] at pro.shushi.pamirs.channel.core.init.ChannelSystemBootAfterInit.init(ChannelSystemBootAfterInit.java:31) 解决办法 方式一【推荐】、配置channel的扫描路径 pamirs: channel: packages: – com.pamirs.ic 方式二、使用Oracle版本的jdk，确保jdk的lib目录，tools.jar有com/sun/tools/javac/tree/JCTree对应的类 问题2：启动报类JsonProvider找不到 具体报错 如果启动报错信息如下： Caused by: java.lang.NoClassDefFoundError: jakarta/json/spi/JsonProvider at java.lang.ClassLoader.defineClass1(Native Method) ~[na:1.8.0_181] at java.lang.ClassLoader.defineClass(ClassLoader.java:763) ~[na:1.8.0_181] at java.security.SecureClassLoader.defineClass(SecureClassLoader.java:142) ~[na:1.8.0_181] at java.net.URLClassLoader.defineClass(URLClassLoader.java:467) ~[na:1.8.0_181] 产生原因 项目中只引入了pamirs-channel-core，但未引入elasticsearch相关的包 解决办法 <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> 其他参考： Oinone引入搜索引擎步骤：https://doc.oinone.top/backend/7235.html
