今天给大家讲讲关于多级网关与多级缓存架构的相关知识，在文章里面，我将从0到1带着大家构建基础服务接口，通过层层递进优化服务，使得服务具备多级缓存的特性，并融合OpenResty拓展一个强大的多级网关+多级缓存的技术架构。以下就是代码实战展示：引入springboot3的maven依赖，本质上作为pom引入，直接管理他的版本号，后续用到啥组件直接拿来即用：<dependencies>  <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter</artifactId> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-web</artifactId> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-configuration-processor</artifactId> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-aop</artifactId> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-jdbc</artifactId> </dependency></dependencies>dependencyManagement依赖管理全代码依赖配置如下：<dependencyManagement> <dependencies>  <dependency> <groupId>mysql</groupId> <artifactId>mysql-connector-java</artifactId> <version>8.0.33</version> </dependency>  <dependency> <groupId>com.baomidou</groupId> <artifactId>mybatis-plus-boot-starter</artifactId> <version>3.5.0</version> </dependency> <dependency> <groupId>com.github.pagehelper</groupId> <artifactId>pagehelper-spring-boot-starter</artifactId> <version>1.4.1</version> </dependency>  <dependency> <groupId>com.fasterxml.jackson.core</groupId> <artifactId>jackson-core</artifactId> <version>2.14.2</version> </dependency> <dependency> <groupId>com.fasterxml.jackson.core</groupId> <artifactId>jackson-annotations</artifactId> <version>2.14.2</version> </dependency> <dependency> <groupId>com.fasterxml.jackson.core</groupId> <artifactId>jackson-databind</artifactId> <version>2.14.2</version> </dependency>  <dependency> <groupId>commons-codec</groupId> <artifactId>commons-codec</artifactId> <version>1.15</version> </dependency> <dependency> <groupId>org.apache.commons</groupId> <artifactId>commons-lang3</artifactId> <version>3.12.0</version> </dependency> <dependency> <groupId>commons-fileupload</groupId> <artifactId>commons-fileupload</artifactId> <version>1.4</version> </dependency> <dependency> <groupId>commons-io</groupId> <artifactId>commons-io</artifactId> <version>2.11.0</version> </dependency> <dependency> <groupId>org.apache.httpcomponents</groupId> <artifactId>httpclient</artifactId> <version>4.5.13</version> </dependency>  <dependency> <groupId>com.google.guava</groupId> <artifactId>guava</artifactId> <version>28.2-jre</version> </dependency> </dependencies></dependencyManagement>使用zaddzset10value120value230value3：设置member和对应的分数zrangezset0-1：查看所有zset中的内容zrangezset0-1withscores：带有分数zrankzsetvalue：获得对应的下标zscorezsetvalue：获得对应的分数zcardzset：统计个数zcountzset分数1分数2：统计个数zrangebyscorezset分数1分数2：查询分数之间的member(包含分数1分数2)zrangebyscorezset(分数1(分数2：查询分数之间的member（不包含分数1和分数2）zrangebyscorezset分数1分数2limitstartend：查询分数之间的member(包含分数1分数2)，获得的结果集再次根据下标区间做查询zremzsetvalue：删除member在common中引入的坐标依赖<dependency> <groupId>org.apache.commons</groupId> <artifactId>commons-lang3</artifactId></dependency><dependency> <groupId>com.fasterxml.jackson.core</groupId> <artifactId>jackson-core</artifactId></dependency><dependency> <groupId>com.fasterxml.jackson.core</groupId> <artifactId>jackson-annotations</artifactId></dependency><dependency> <groupId>com.fasterxml.jackson.core</groupId> <artifactId>jackson-databind</artifactId></dependency><dependency> <groupId>com.fasterxml.jackson.datatype</groupId> <artifactId>jackson-datatype-jsr310</artifactId></dependency>迭代查询代码，一级缓存与二级缓存结合:@GetMapping("query")publicObjectquery(Stringid){ StringarticleKey="article:"+id; StringarticleKeyRedis="REDIS_ARTICLE:"+id; Articlearticle=cache.get(articleKey,s->{ System.out.println("文章id为"+id+"的没有查询到，则从Redis中查询后返回..."); ArticlearticleReal=null; StringarticleJsonStr=redis.get(articleKeyRedis); //判断从redis中查询到的文章数据是否为空 if(StringUtils.isBlank(articleJsonStr)){ System.out.println("Redis中不存在该文章，将从数据库中查询..."); //如果为空，则进入本条件，则从数据库中查询数据 articleReal=articleService.queryArticleDetail(id); //手动把文章数据设置到redis中，后续再次查询则有值 StringarticleJson=JsonUtils.objectToJson(articleReal); redis.set(articleKeyRedis,articleJson); }else{ System.out.println("Redis中存在该文章，将直接返回..."); //如果不为空，则直接转换json类型article再返回即可 articleReal=JsonUtils.jsonToPojo(articleJsonStr,Article.class); } returnarticleReal; }); returnarticle;}本文到此结束，感谢大家的阅读！
