本文介绍了一个关于Spring Boot Redis与Netty 5.0.0 Alpha1版本之间的兼容性问题。当同时引入这两个依赖时，应用启动失败。问题在于Spring Boot Redis引入的lettuce与Netty的不同版本之间存在冲突。解决方案是在引入common模块时排除lettuce-core。

spring boot redis和netty5.0.0冲突

        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-data-redis</artifactId>
        </dependency>
        <dependency>
            <groupId>io.netty</groupId>
            <artifactId>netty-all</artifactId>
            <version>5.0.0.Alpha1</version>
        </dependency>

启动的时候会出现如下错误:

***************************
APPLICATION FAILED TO START
***************************

Description:

An attempt was made to call the method io.netty.bootstrap.Bootstrap.channel(Ljava/lang/Class;)Lio/netty/bootstrap/Bootstrap; but it does not exist. Its class, io.netty.bootstrap.Bootstrap, is available from the following locations:

    jar:file:/F:/repository/io/netty/netty-transport/4.1.29.Final/netty-transport-4.1.29.Final.jar!/io/netty/bootstrap/Bootstrap.class
    jar:file:/F:/repository/io/netty/netty-all/5.0.0.Alpha1/netty-all-5.0.0.Alpha1.jar!/io/netty/bootstrap/Bootstrap.class

It was loaded from the following location:

    file:/F:/repository/io/netty/netty-transport/4.1.29.Final/netty-transport-4.1.29.Final.jar

问题分析：
spring-boot-starter-data-redis 引入了lettuce，
而lettuce又关联了

        <!-- Netty -->

        <dependency>
            <groupId>io.netty</groupId>
            <artifactId>netty-common</artifactId>
        </dependency>

        <dependency>
            <groupId>io.netty</groupId>
            <artifactId>netty-transport</artifactId>
        </dependency>

        <dependency>
            <groupId>io.netty</groupId>
            <artifactId>netty-handler</artifactId>
        </dependency>

maven结构说明：
common模块引入的 spring-boot-starter-data-redis、netty-all
biz模块引入common模块
xxx模块，引入common模块、biz模块

解决思路：
xxx模块引入common模块时，排除lettuce-core即可！

        <dependency>
            <groupId>com.xxx.xxx</groupId>
            <artifactId>common</artifactId>
             <exclusions>
                 <exclusion>
                     <groupId>io.lettuce</groupId>
                     <artifactId>lettuce-core</artifactId>
                 </exclusion>
             </exclusions>
        </dependency>
