Redis 和 Mysql 数据库数据如何保持一致性

1.创建srpingBoot的工程

2.pom文件如下，如果出现无法正确读取nacos的配置，很大程度是因为jar包的版本问题导致，当前我使用的是

springBoot的版本：

<parent>
   <groupId>org.springframework.boot</groupId>
   <artifactId>spring-boot-starter-parent</artifactId>
   <version>2.7.18</version>
   <relativePath/> <!-- lookup parent from repository -->
</parent>

nacos相关的版本

<dependency>
   <groupId>com.alibaba.cloud</groupId>
   <artifactId>spring-cloud-starter-alibaba-nacos-discovery</artifactId>
   <version>2021.0.1.0</version>
</dependency>
<dependency>
   <groupId>com.alibaba.cloud</groupId>
   <artifactId>spring-cloud-starter-alibaba-nacos-config</artifactId>
   <version>2021.0.1.0</version>
</dependency>

3.yaml文件配置：

spring:
  profiles:
    active: dev
  application:
    name: cloud-gateway
  cloud:
    nacos:
      discovery:
        server-addr: localhost:8848
        namespace: 1c88f9d9-1f33-4460-9764-35603afb851a
        username: nacos
        password: nacos
      config:
        server-addr: localhost:8848
        namespace: 1c88f9d9-1f33-4460-9764-35603afb851a
        username: nacos
        password: nacos
        file-extension: yaml
        extension-configs:
          - data-id: application-dev.yaml
#            group: DEFAULT_GROUP
#            refresh: true
  config:
    import: nacos:application-dev.yaml
