#spring boot #redis #java

原因：Netty 版本不兼容

因为我本来只使用了redis，但是后来又引入了netty，同时在pom.xml中引入了如下两个依赖：

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-data-redis</artifactId>
</dependency>
<dependency>
    <groupId>io.netty</groupId>
    <artifactId>netty-all</artifactId>
    <version>4.1.68.Final</version>
</dependency>

由于spring-boot-starter-data-redis依赖于lettuce-core，而lettuce-core又依赖于特定版本的netty的部分组件，和我在pom.xml中引入的netty版本出现了版本冲突

改为如下的版本后成功解决：

<dependency>
    <groupId>io.netty</groupId>
    <artifactId>netty-all</artifactId>
    <version>4.1.74.Final</version>
</dependency>

报错如下：
