随着现代软件系统的复杂性和用户需求的多样化，异步编程成为了提升系统性能和响应速度的重要手段。在Java领域，CompletableFuture作为Java 8引入的新特性，提供了强大的异步编程能力，极大地简化了多线程和并发任务的处理。本文将探讨CompletableFuture的基本功能和使用方法，介绍如何利用其提升程序的并发性能和代码的可维护性。

其原理相关内容见：CompletableFuture回调机制的设计与实现_张彦峰ZYF的博客-CSDN博客

一、CompletableFuture基本功能安利

CompletableFuture是JDK8中的新特性，主要用于对JDK5中加入的Future的补充，实现了CompletionStage和Future接口。其基本功能主要如下图，作为一项利器在我们的平时开发中频繁使用。

一般使用上我们主要集中在任务创建、异步回调、多任务组合、结果处理和结果获取，本文主要针对各部分主要功能进行基本的安利使用，同时附上一些源码的文章供分析。

二、CompletableFuture使用介绍

假设我们有一个敏感词系统，可以针对各种信息进行基本的敏感词验证，其核心主要包括三部分功能：文本清洗、敏感词验证、敏感词干预生效。

第一步，文本清洗针对验证的文本将直接去除其中的特殊符号、表情包、隐藏符号、中文简体繁体转换等内容，只保留文本中含有的中英文和数字信息。
第二步，清洗后，将清洗文本与实际相关的词库进行验证来查看是否命中相关敏感词，并给出词库命中的敏感词信息。
第三步，如果存在词库命中的敏感词，同时考虑各词是否有加白以及生效规则（只对某区域生效等），从而确定最终的命中信息。

以上是业务基背景，相关可以采用责任链管道模式实现可见责任链模式（以及变种管道模式）的应用案例_张彦峰ZYF的博客-CSDN博客_责任链模式应用场景责任链在实际开发中的应用还是比较多的，特别是在营销订购系统、审核流转换处理、任务流程处理系统等系统中，其实我们在开发中往往主要应用的主要无非是以下三个场景（起码以我的平时开发的角度来看）：一是无需太关心责任链中各处理流的顺序的简单使用；二是需要关注处理顺序，按责任链条延续处理，每个处理节点均可对请求进行节点的处理，或将其传递给链上的下个处理节点；三是在处理中和纯的责任链模式在链上只会有一个处理器用于处理业务数据存在差异，需要进行管道模式采用多个处理器都会处理业务数据。针对以上场景进行业务举例和代码书写https://blog.csdn.net/xiaofeng10330111/article/details/123956717?spm=1001.2014.3001.5501其中含有基本业务流程图可方便理解。

（一）任务创建使用

1.supplyAsync创建带有返回值的异步任务

public static <U> CompletableFuture<U> supplyAsync(Supplier<U> supplier)
public static <U> CompletableFuture<U> supplyAsync(Supplier<U> supplier, Executor executor)

我们限定创建用于清洗用户文本有返回值的异步任务，采用以下两种方式进行展示其基本创建：

使用默认线程池（ForkJoinPool.commonPool()）异步任务创建-有返回值的异步任务supplyAsync
自定义线程池异步任务创建-有返回值的异步任务supplyAsync

使用举例代码：

/*** @author yanfengzhang* @description CompletableFuture使用* @date 2022/12/29  23:45*/
@RunWith(SpringRunner.class)
@SpringBootTest(classes = ZYFApplication.class, webEnvironment = SpringBootTest.WebEnvironment.RANDOM_PORT)
@Slf4j
public class CompletableFutureTest {@Autowiredprivate SensitivePipelineExecutor sensitivePipelineExecutor;/*** 异步任务创建：有返回值的异步任务supplyAsync* 使用默认线程池 + 自定义线程池*/@Testpublic void testSupplyAsync() throws ExecutionException, InterruptedException {log.info("异步任务创建-有返回值的异步任务supplyAsync:使用默认线程池（ForkJoinPool.commonPool()）");CompletableFuture<String> contentCleanTaskByDefault = CompletableFuture.supplyAsync(() -> {log.info("异步任务获取用户文本清洗结果：用户文本【中國張彥峰㎵㎶㎷㎸㎹㎺外賣⏳⌚⏰】");ContentCleanResContext contentCleanResContext = sensitivePipelineExecutor.getContentCleanRes(ContentInfoContext.builder().content("中國張彥峰㎵㎶㎷㎸㎹㎺外賣⏳⌚⏰").cleanContent("中國張彥峰㎵㎶㎷㎸㎹㎺外賣⏳⌚⏰").contentAttr(ContentAttr.builder().build()).build());return contentCleanResContext.getCleanContent();});log.info("异步任务获取用户文本清洗结果：【{}】", contentCleanTaskByDefault.get());log.info("异步任务创建-有返回值的异步任务supplyAsync:自定义线程池");ThreadPoolExecutor threadPoolExecutor = new ThreadPoolExecutor(8,16, 5, TimeUnit.MINUTES, new LinkedBlockingQueue<>(), new ThreadFactory() {private AtomicInteger threadCount = new AtomicInteger(1);@Overridepublic Thread newThread(Runnable r) {return new Thread(r, "thread-processor-" + threadCount.getAndIncrement());}});CompletableFuture<String> contentCleanTaskByDefine = CompletableFuture.supplyAsync(() -> {log.info("异步任务获取用户文本清洗结果：用户文本【中國張彥峰㎵㎶㎷㎸㎹㎺外賣⏳⌚⏰】");ContentCleanResContext contentCleanResContext = sensitivePipelineExecutor.getContentCleanRes(ContentInfoContext.builder().content("中國張彥峰㎵㎶㎷㎸㎹㎺外賣⏳⌚⏰").cleanContent("中國張彥峰㎵㎶㎷㎸㎹㎺外賣⏳⌚⏰").contentAttr(ContentAttr.builder().bizType(BizType.E_COMMERCE.getType()).cityCode(110010).build()).build());return contentCleanResContext.getCleanContent();}, threadPoolExecutor);log.info("异步任务获取用户文本清洗结果：【{}】", contentCleanTaskByDefine.get());}
}

2.runAsync创建没有返回值的异步任务

public static CompletableFuture<Void> runAsync(Runnable runnable)
public static CompletableFuture<Void> runAsync(Runnable runnable,Executor executor)

我们限定创建用于清洗用户文本无返回值的异步任务，采用以下两种方式进行展示其基本创建：

使用默认线程池（ForkJoinPool.commonPool()）异步任务创建-无返回值的异步任务supplyAsync
自定义线程池异步任务创建-无返回值的异步任务supplyAsync

因为无返回值，所以一般在处理中，异步任务对用户文本清洗并刷新数据到指定缓存，并"异步通知进行消息转发，触达各消费端进行后续清理

使用举例代码：

/*** @author yanfengzhang* @description CompletableFuture使用* @date 2022/12/29  23:45*/
@RunWith(SpringRunner.class)
@SpringBootTest(classes = ZYFApplication.class, webEnvironment = SpringBootTest.WebEnvironment.RANDOM_PORT)
@Slf4j
public class CompletableFutureTest {/*** 异步任务创建：没有返回值的异步任务runAsync* 使用默认线程池 + 自定义线程池*/@Testpublic void testRunAsync() throws ExecutionException, InterruptedException {log.info("异步任务创建-有返回值的异步任务runAsync:使用默认线程池（ForkJoinPool.commonPool()）");CompletableFuture<Void> contentCleanTaskByDefault = CompletableFuture.runAsync(() -> {log.info("异步任务对用户文本清洗并刷新数据");log.info("异步通知进行消息转发，触达各消费端进行后续清理");});log.info("异步任务创建-有返回值的异步任务runAsync:自定义线程池");ThreadPoolExecutor threadPoolExecutor = new ThreadPoolExecutor(8,16, 5, TimeUnit.MINUTES, new LinkedBlockingQueue<>(), new ThreadFactory() {private AtomicInteger threadCount = new AtomicInteger(1);@Overridepublic Thread newThread(Runnable r) {return new Thread(r, "thread-processor-" + threadCount.getAndIncrement());}});CompletableFuture<Void> contentCleanTaskByDefine = CompletableFuture.runAsync(() -> {log.info("异步任务对用户文本清洗并刷新数据");log.info("异步通知进行消息转发，触达各消费端进行后续清理");}, threadPoolExecutor);}
}

（二）异步回调使用

1.异步回调：thenApply和thenApplyAsync

public <U> CompletableFuture<U> thenApply(Function<? super T,? extends U> fn)
public <U> CompletableFuture<U> thenApplyAsync(Function<? super T,? extends U> fn) 
public <U> CompletableFuture<U> thenApplyAsync(Function<? super T,? extends U> fn,Executor executor)

我们限定两个任务来完成用户文本的清洗和词库命中情况，采用以下两种方式进行展示，注意这两个方法是有返回值的：

异步回调-thenApply使用，任务一将用户文本进行清洗，任务二回调清洗结果查看数据数据命中敏感词情况
异步回调-thenApplyAsync使用，任务一将用户文本进行清洗，任务二回调清洗结果查看数据数据命中敏感词情况，采用自定义线程池

使用举例代码：

/*** @author yanfengzhang* @description CompletableFuture使用* @date 2022/12/29  23:45*/
@RunWith(SpringRunner.class)
@SpringBootTest(classes = ZYFApplication.class, webEnvironment = SpringBootTest.WebEnvironment.RANDOM_PORT)

}

2.异步回调：thenCompose和thenComposeAsync

public <U> CompletableFuture<U> thenCompose(Function<? super T, ? extends CompletionStage<U>> fn)
public <U> CompletableFuture<U> thenComposeAsync(Function<? super T, ? extends CompletionStage<U>> fn)
public <U> CompletableFuture<U> thenComposeAsync(Function<? super T, ? extends CompletionStage<U>> fn, Executor executor)

我们限定两个任务来完成用户文本的清洗和词库命中情况，采用以下两种方式进行展示，注意这两个方法是有返回值的：

异步回调-thenCompose使用，任务一将用户文本进行清洗，任务二回调清洗结果查看数据数据命中敏感词情况
异步回调-thenComposeAsync使用，任务一将用户文本进行清洗，任务二回调清洗结果查看数据数据命中敏感词情况

3.异步回调：thenAccept和thenAcceptAsync

public CompletableFuture<Void> thenAccept(Consumer<? super T> action)
public CompletableFuture<Void> thenAcceptAsync(Consumer<? super T> action) 
public CompletableFuture<Void> thenAcceptAsync(Consumer<? super T> action, Executor executor)

我们限定两个任务来完成用户文本的清洗和词库命中情况，采用以下两种方式进行展示，注意这两个方法是没有返回值的：

异步回调-thenAccept使用，任务一将用户文本进行清洗，任务二回调清洗结果查看数据数据命中敏感词情况
异步回调-thenAcceptAsync使用，任务一将用户文本进行清洗，任务二回调清洗结果查看数据数据命中敏感词情况，使用自定义线程池

（三）多任务组合使用

1.多任务组合：thenCombine

public <U,V> CompletableFuture<V> thenCombine(CompletionStage<? extends U> other, BiFunction<? super T,? super U,? extends V> fn)
public <U,V> CompletableFuture<V> thenCombineAsync(CompletionStage<? extends U> other, BiFunction<? super T,? super U,? extends V> fn)
public <U,V> CompletableFuture<V> thenCombineAsync(CompletionStage<? extends U> other, BiFunction<? super T,? super U,? extends V> fn, Executor executor)

我们限定用户文本的清洗完成清洗，然后异步查看企业合规管控处理查看数据数据命中敏感词情况和正则校验处理查看数据数据命中敏感词情况，只要有一个词库反馈不命中就认为商品可以售卖，该方法有具体返回值。

2.多任务组合：thenAcceptBoth

public <U> CompletableFuture<Void> thenAcceptBoth(CompletionStage<? extends U> other, BiConsumer<? super T, ? super U> action)
public <U> CompletableFuture<Void> thenAcceptBothAsync(CompletionStage<? extends U> other, BiConsumer<? super T, ? super U> action)
public <U> CompletableFuture<Void> thenAcceptBothAsync(CompletionStage<? extends U> other, BiConsumer<? super T, ? super U> action, Executor executor)

我们限定用户文本的清洗完成清洗，然后异步查看企业合规管控处理查看数据数据命中敏感词情况和正则校验处理查看数据数据命中敏感词情况，只要有一个词库反馈不命中就认为商品可以售卖异步处理商品上架，否则对商品直接下架处理并告知下架理由为存在敏感词，该方法没有返回值，相关操作建议进行异步操作处理。

public CompletableFuture<Void> runAfterBothAsync(CompletionStage<?> other, Runnable action)
public CompletableFuture<Void> runAfterBothAsync(CompletionStage<?> other, Runnable action, Executor executor)

5.多任务组合：acceptEither

public CompletableFuture<Void> acceptEither(CompletionStage<? extends T> other, Consumer<? super T> action)
public CompletableFuture<Void> acceptEitherAsync(CompletionStage<? extends T> other, Consumer<? super T> action)
public CompletableFuture<Void> acceptEitherAsync(CompletionStage<? extends T> other, Consumer<? super T> action, Executor executor)

我们限定用户文本的清洗完成清洗，然后异步查看企业合规管控处理查看数据数据命中敏感词情况和正则校验处理查看数据数据命中敏感词情况，只要有一个词库反馈不命中就认为商品可以售卖, 该方式下我们只关心最先返回的命中结果就进行后续操作，一般要求业务两边的校验处理结果是保持一致的，本处只做模拟使用，注意该方式没有返回值，处理结果需要异步操作。

7.多任务组合：allOf

public static CompletableFuture<Void> allOf(CompletableFuture<?>... cfs)

我们限定用户文本的清洗完成清洗，然后异步查看词库情况，按一下两种情况进行分析

情况一：当给定的多个异步任务都正常完成后，返回一个新的 CompletableFuture，给定 CompletableFuture 的结果不会反映在返回的 CompletableFuture 中，但可以通过单独检查给定任务来获得结果
情况二：当任何一个异步任务异常完成，则返回的CompletableFuture 也会异常完成，并且将该异步任务的异常作为其原因
情况三：当存在多个异常完成时，则返回排在前面的异步任务的异常信息。

具体代码如下，各自验证结果分开验证：

（四）结果处理使用

1.结果处理：whenComplete

public CompletableFuture<T> whenComplete(BiConsumer<? super T, ? super Throwable> action)
public CompletableFuture<T> whenCompleteAsync(BiConsumer<? super T, ? super Throwable> action) 
public CompletableFuture<T> whenCompleteAsync(BiConsumer<? super T, ? super Throwable> action, Executor executor)

我们限定对用户文本清洗后，异步进行通知，对原返回结果不做干预，有异常则中断，注意该方法是没有返回值的。

}

（五）方法混合使用举例

1.多个方法组合使用

回到刚开始的敏感词系统，将核心功能：文本清洗、敏感词验证、敏感词干预生效在同一个服务中连贯处理：

第一步，文本清洗针对验证的文本将直接去除其中的特殊符号、表情包、隐藏符号、中文简体繁体转换等内容，只保留文本中含有的中英文和数字信息。
第二步，清洗后，将清洗文本与实际相关的词库进行验证来查看是否命中相关敏感词，并给出词库命中的敏感词信息。
第三步，如果存在词库命中的敏感词，同时考虑各词是否有加白以及生效规则（只对某区域生效等），从而确定最终的命中信息。

原文本【中國張彥峰㎵㎶㎷㎸㎹㎺外賣⏳⌚⏰,腾讯,南京酒精】中对应[中国，张彦峰,外卖，腾讯, 酒精, 南京]都是各个词库要求的敏感词，但是对于[中国，外卖]是针对业务做的加白处理等，所以实际生效敏感词是[张彦峰, 腾讯, 酒精, 南京]

使用举例代码：

2.并发处理批量任务

假设线上可以对于运营批量新建的商品数据内容进行敏感词分析，针对批量创建的各个商品针对其相关信息（商品名称/商品描述/分类和分类描述/规格名称/属性和属性值/套餐/商品图片特效/商品普通属性和属性值/商家名称/商家公告等）进行敏感词监控并给出对应的结果报告，显然商品数据居多这样的内容建议采用多线程批发处理，此时异步的优势就体现了，具体实现我们按以下方式进行模拟实现：

A.模拟规定校验商品敏感词信息归类

/*** @author yanfengzhang* @description 校验商品敏感词信息归类* @date 2023/1/4  23:00*/
public enum SensitiveValidateField {NAME(1, "商品名称"),DESCRIPTION(2, "商品描述"),TAG_NAME(3, "分类和分类描述"),SPEC(4, "规格名称"),ATTR_NAME(5, "属性和属性值"),COMBO_MEAL(6, "套餐"),SPECIAL_EFFECT_PIC(7, "商品图片特效"),CUSTOM_ATTR_NAME(8, "自定义属性"),ORDINARY_ATTR_NAME(9, "商品普通属性和属性值"),SP_NAME(10, "标品名称"),POI_NAME(11, "商家名称"),POI_ANNOUNCEMENT(12, "商家公告");/*** 文本归类（商品名称、商品描述、商家公告、商家名称、经营描述、代言信息等）*/private Integer type;/*** 文本归类描述*/private String desc;public Integer getType() {return type;}public String getDesc() {return desc;}SensitiveValidateField(Integer code) {this.type = code;}SensitiveValidateField(Integer code, String desc) {this.desc = desc;this.type = code;}/*** 根据文本归类type获取对应的文本归类信息** @param type 文本归类type* @return*/public static SensitiveValidateField getEnumById(Integer type) {for (SensitiveValidateField sensitiveValidateField : SensitiveValidateField.values()) {if (sensitiveValidateField.getType().equals(type)) {return sensitiveValidateField;}}return null;}/*** 根据文本归类信息描述获取对应的文本归类信息** @param desc 文本归类描述* @return*/public static SensitiveValidateField getEnumByDesc(String desc) {for (SensitiveValidateField sensitiveValidateField : SensitiveValidateField.values()) {if (sensitiveValidateField.getDesc().equals(desc)) {return sensitiveValidateField;}}return null;}/*** 判断文本归类type是否在指定范围** @param type 文本归类type* @return true-在指定范围*/public static boolean isSensitiveValidateField(Integer type) {if (null == type) {return false;}for (SensitiveValidateField tempEnum : SensitiveValidateField.values()) {if (tempEnum.getType().equals(type)) {return true;}}return false;}

B.模拟从一个上传的商品信息中提炼商品内含的文本数据

    /*** 模拟从一个上传的商品信息中提炼商品内含的文本数据** @return*/private List<ContentInfoContext> getContentInfosBySpu() {List<ContentInfoContext> contentInfoContexts = Lists.newArrayList();List<String> spuInfoList = Lists.newArrayList("張彥峰", "肯德基", "外賣", "腾讯", "禁药", "酒精南京","18252066688", "饿了吗", "廉政勤政", "中国", "巴黎圣母院", "莫沫南路", "辉瑞P药", "捷倍安", "极速达", "老城一埚","星即送", "连花清温", "美乐滋", "山茱萸", "欧美齐", "长江鱼", "人气榜第一", "蟹礼券", "茶ta颜悦色", "可食用黄金","安培开席", "摇钱树", "特丁通", "草甘膦", "叫只鸡", "贱男消食片", "维信识别", "龙闩花甲", "鮑家糕点", "至尊至比萨","胖大哥肉蟹煲", "OBLIGI韩式炸鸡", "星芭芭", "欢乐柠檬", "水多活好", "胸胸烈火", "比基妮", "成人艺术", "仿真手枪", "机关枪");for (int i = 0; i < 12; i++) {String contentInfo = spuInfoList.get(getRandomNumberInRange(0, spuInfoList.size() - 1)) + spuInfoList.get(getRandomNumberInRange(0, spuInfoList.size() - 1))+ spuInfoList.get(getRandomNumberInRange(0, spuInfoList.size() - 1));contentInfoContexts.add(ContentInfoContext.builder().content(contentInfo).cleanContent(contentInfo).contentAttr(ContentAttr.builder().belong(SensitiveValidateField.getEnumById(i + 1)).bizType(BizType.E_COMMERCE.getType()).cityCode(110010).build()).build());}return contentInfoContexts;}private static int getRandomNumberInRange(int min, int max) {Random r = new Random();return r.ints(min, (max + 1)).limit(1).findFirst().getAsInt();}

C.模拟处理一个商品信息中的敏感词命中情况统计,异步并发

    /*** 模拟处理一个商品信息中的敏感词命中情况统计*/private String  containsSensitiveWordSpu(SpuSensitiveDealCommand spuSensitiveDealCommand) {/*1.模拟从一个上传的商品信息中提炼商品内含的文本数据*/List<ContentInfoContext> spuContentInfos = getContentInfosBySpu();/*2.对商品各项数据进行校验检查*/ThreadPoolExecutor threadPoolExecutor = new ThreadPoolExecutor(8,16, 5, TimeUnit.MINUTES, new LinkedBlockingQueue<>(), new ThreadFactory() {private AtomicInteger threadCount = new AtomicInteger(1);@Overridepublic Thread newThread(Runnable r) {return new Thread(r, "thread-processor-" + threadCount.getAndIncrement());}});int isHit = 1;int exceptionHit = 2;List<CompletableFuture<Map<Integer, String>>> spuSensitiveDealRes = spuContentInfos.stream().map(contentInfoContext -> {return CompletableFuture.supplyAsync(() -> {return sensitivePipelineExecutor.getContentCleanRes(contentInfoContext);}, threadPoolExecutor).thenComposeAsync(new Function<ContentCleanResContext, CompletionStage<SensitveHitContext>>() {@Overridepublic CompletionStage<SensitveHitContext> apply(ContentCleanResContext contentCleanResInfo) {return CompletableFuture.supplyAsync(new Supplier<SensitveHitContext>() {@Overridepublic SensitveHitContext get() {return sensitivePipelineExecutor.getSensitveHitRes(contentCleanResInfo);}});}}, threadPoolExecutor).thenApplyAsync((sensitveHitContext) ->sensitivePipelineExecutor.getSensitveEffectiveRes(sensitveHitContext), threadPoolExecutor).handle((res, excption) -> {Map<Integer, String> hitdetail = Maps.newHashMap();StringBuilder hitInfoRes = new StringBuilder();hitInfoRes.append("【").append(contentInfoContext.getContentAttr().getBelong().getDesc()).append("】[").append(contentInfoContext.getContent()).append("]");/*异步方法执行完的后续处理*/if (Objects.nonNull(excption)) {log.info("执行发生异常，返回默认数据，异常信息为：" + excption);hitInfoRes.append("校验敏感词异常:").append(excption.getMessage());hitdetail.put(exceptionHit, hitInfoRes.toString());return hitdetail;}if (!res.getIsHit()) {return hitdetail;}log.info("异步任务成功执行,上一步的结果是：" + res);hitInfoRes.append("命中敏感词:").append(res.getHitWords().stream().map(SensitiveWord::getSensitive).collect(Collectors.toList()).toString());hitdetail.put(isHit, hitInfoRes.toString());return hitdetail;});}).collect(Collectors.toList());/*3.等待所有并行线程完成，结束单词单词商品处理*/CompletableFuture.allOf(spuSensitiveDealRes.toArray(new CompletableFuture[]{})).join();threadPoolExecutor.shutdown();/*4.整合单商品最终结果*/List<String> validHits = Lists.newArrayList();List<String> exceptionHits = Lists.newArrayList();spuSensitiveDealRes.stream().forEach(hitInfo -> {Map<Integer, String> hitdetail;try {hitdetail = hitInfo.get();} catch (Exception e) {return;}if (MapUtils.isEmpty(hitdetail)) {return;}if (StringUtils.isNotBlank(hitdetail.get(isHit))) {validHits.add(hitdetail.get(isHit));}if (StringUtils.isNotBlank(hitdetail.get(exceptionHit))) {exceptionHits.add(hitdetail.get(exceptionHit));}});/*4.1 如果没有命中敏感词以及异常情况直接返回*/String spuName = spuContentInfos.stream().filter(contentInfoContext -> contentInfoContext.getContentAttr().getBelong() == SensitiveValidateField.NAME).findFirst().get().getContent();StringBuilder hitInfoRes = new StringBuilder();if (CollectionUtils.isEmpty(validHits) && CollectionUtils.isEmpty(exceptionHits)) {hitInfoRes.append("商品【").append(spuName).append("】未命中敏感词");return hitInfoRes.toString();}/*4.2 统计其中有效命中信息*/if (CollectionUtils.isNotEmpty(validHits)) {hitInfoRes.append("商品【").append(spuName).append("】敏感词命中情况统计：\n");validHits.stream().forEach(hitInfo -> {hitInfoRes.append(hitInfo).append("\n");});}/*4.3 统计其中异常命中信息*/if (CollectionUtils.isNotEmpty(exceptionHits)) {hitInfoRes.append("商品【").append(spuName).append("】敏感词异常处理情况统计：\n");exceptionHits.stream().forEach(hitInfo -> {hitInfoRes.append(hitInfo).append("\n");});}return hitInfoRes.toString();}

D.模拟并发处理批量任务

    /*** 并发处理批量任务* <p>* 测试组合敏感词处理逻辑*/@Testpublic void testSensitiveBatchDeal() throws ExecutionException, InterruptedException {/*定义单个商品处理任务*/class SpuSentiveTask implements Callable<String> {private final SpuSensitiveDealCommand command;public SpuSentiveTask(SpuSensitiveDealCommand command) {this.command = command;}@Overridepublic String call() throws Exception {return containsSensitiveWordSpu(command);}}/*模拟批量商品 假设前端传入十个商品，我们将十个商品并发执行*/ThreadPoolExecutor threadPoolExecutor = new ThreadPoolExecutor(8,16, 5, TimeUnit.MINUTES, new LinkedBlockingQueue<>(), new ThreadFactory() {private AtomicInteger threadCount = new AtomicInteger(1);@Overridepublic Thread newThread(Runnable r) {return new Thread(r, "thread-processor-" + threadCount.getAndIncrement());}});List<SpuSentiveTask> spuSentiveTasks = Lists.newArrayList();for (int i = 0; i < 10; i++) {spuSentiveTasks.add(new SpuSentiveTask(new SpuSensitiveDealCommand()));}List<Future<String>> spuSensitiveBatchRes = threadPoolExecutor.invokeAll(spuSentiveTasks);threadPoolExecutor.shutdown();if (CollectionUtils.isEmpty(spuSensitiveBatchRes)) {log.info("本批次商品数据中不存在敏感词！");return;}final int[] i = {0};spuSensitiveBatchRes.forEach(spuSensitiveRes -> {try {log.info("商品编号{}对应敏感词校验情况如下：", i[0]);log.info(spuSensitiveRes.get());i[0]++;} catch (Exception e) {log.error("商品编号{}对应敏感词校验情况提取失败", i[0]);i[0]++;}});}
