简介: Spring Boot集成Redis启动失败【Caused by: java.lang.ClassNotFoundException: org.apache.commons.pool2.impl.G】

项目场景

今天在使用Spring Boot集成Redis搭建项目学习分布式锁的时候,在pom.xml文件引入Redis的相关依赖后,在配置文件application.properties进行了基础的redis配置,启动项目后,发现项目启动失败。


问题描述

项目的基本结构如下:
在这里插入图片描述

pom.xml

 <dependencies>
         <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-web</artifactId>
        </dependency>

        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-test</artifactId>
            <scope>test</scope>
        </dependency>

       <dependency>
           <groupId>org.springframework.boot</groupId>
           <artifactId>spring-boot-starter-data-redis</artifactId>
       </dependency>

        <!--  工具依赖  -->
        <dependency>
            <groupId>org.projectlombok</groupId>
            <artifactId>lombok</artifactId>
            <optional>true</optional>
        </dependency>

        <!--引入hutool工具包-->
        <dependency>
            <groupId>cn.hutool</groupId>
            <artifactId>hutool-all</artifactId>
        </dependency>

配置文件application.properties

# Redis数据库索引(默认为0)
spring.redis.database=1
  # Redis服务器地址
spring.redis.host=127.0.0.1
  # Redis服务器连接端口
spring.redis.port=6379
  # Redis服务器连接密码(默认为空)
spring.redis.password=

  # 连接池最大连接数(使用负值表示没有限制) 默认 8
spring.redis.lettuce.pool.max-active=8
  # 连接池最大阻塞等待时间(使用负值表示没有限制) 默认 -1
spring.redis.lettuce.pool.max-wait=-1
  # 连接池中的最大空闲连接 默认 8
spring.redis.lettuce.pool.max-idle=8
  # 连接池中的最小空闲连接 默认 0
spring.redis.lettuce.pool.min-idle=0

启动redis服务后,然后启动项目启动失败

在这里插入图片描述

通过检查日志分析发现:
在这里插入图片描述
无法创建redis连接池redisConnectionFactory!!!

于是检查了一下redis的依赖和相关配置,都没有发现问题所在。

继续向下分析日志,发现:
在这里插入图片描述
找不到类GenericObjectPoolConfig!!!即没有配置这个类的依赖。

因为在application.properties文件中配置了redis的连接池信息,而连接池需要使用这个依赖。


解决方案

在pom.xml文件中引入依赖:

<dependency>
    <groupId>org.apache.commons</groupId>
    <artifactId>commons-pool2</artifactId>
</dependency>

刷新依赖,重启项目,项目启动成功。

【MongoDB 专栏】MongoDB 与 Spring Boot 的集成实践
【5月更文挑战第11天】本文介绍了如何将非关系型数据库MongoDB与Spring Boot框架集成,以实现高效灵活的数据管理。Spring Boot简化了Spring应用的构建和部署,MongoDB则以其对灵活数据结构的处理能力受到青睐。集成步骤包括:添加MongoDB依赖、配置连接信息、创建数据访问对象(DAO)以及进行数据操作。通过这种方式,开发者可以充分利用两者优势,应对各种数据需求。在实际应用中,结合微服务架构等技术,可以构建高性能、可扩展的系统。掌握MongoDB与Spring Boot集成对于提升开发效率和项目质量至关重要,未来有望在更多领域得到广泛应用。

springboot业务开发--springboot集成redis解决缓存雪崩穿透问题
该文介绍了缓存使用中可能出现的三个问题及解决方案:缓存穿透、缓存击穿和缓存雪崩。为防止缓存穿透,可校验请求数据并缓存空值;缓存击穿可采用限流、热点数据预加载或加锁策略;缓存雪崩则需避免同一时间大量缓存失效,可设置随机过期时间。文章还提及了Spring Boot中Redis缓存的配置,包括缓存null值、使用前缀和自定义过期时间,并提供了改造代码以实现缓存到期时间的个性化设置。
