错误背景

集成redisson出现这个错误

redisson的maven依赖如下:

<dependency>
   <groupId>org.redisson</groupId>
   <artifactId>redisson-spring-boot-starter</artifactId>
   <version>3.11.4</version>
</dependency>

错误原因分析

这是因为redisson里有spring-boot-starter-web导致的。因为我的springcloud-gateway也有这个依赖，依赖冲突导致启动报错。

解决办法

排除依赖即可，如下:

<dependency>
      <groupId>org.redisson</groupId>
      <artifactId>redisson-spring-boot-starter</artifactId>
      <version>3.11.4</version>
      <exclusions>
          <exclusion>
              <groupId>org.springframework.boot</groupId>
              <artifactId>spring-boot-starter-web</artifactId>
          </exclusion>
          <exclusion>
              <groupId>org.springframework.boot</groupId>
              <artifactId>spring-boot-starter-webflux</artifactId>
          </exclusion>
      </exclusions>
 </dependency>
