spring-boot - Spring Boot 2 无法连接到 Redis

Question

我正在尝试将 Lettuce 驱动程序与 Spring Boot 2 和 Spring Data Redis(均为最新版本)结合使用。我无法连接到 Redis，我不断收到以下错误:

Caused by: java.lang.ClassNotFoundException: io.lettuce.core.KeyValue
    at java.net.URLClassLoader.findClass(URLClassLoader.java:381) ~[na:1.8.0_111]
    at java.lang.ClassLoader.loadClass(ClassLoader.java:424) ~[na:1.8.0_111]
    at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:331) ~[na:1.8.0_111]
    at java.lang.ClassLoader.loadClass(ClassLoader.java:357) ~[na:1.8.0_111]
    ... 148 common frames omitted

我想使用响应式(Reactive)连接，所以我覆盖了 connectionFactory 配置类

@Configuration
class RedisConfig {

    @Bean
    fun reactiveRedisConnection(redisConnectionFactory: ReactiveRedisConnectionFactory): ReactiveRedisConnection {
        return redisConnectionFactory.reactiveConnection
    }

    @Bean
    fun redisConnectionFactory(): LettuceConnectionFactory {
        return LettuceConnectionFactory()
    }
}

应用程序属性

## Redis config
spring.redis.host=192.168.99.100
spring.redis.port=32769

构建.gradle

dependencies {
    compile("org.springframework.boot:spring-boot-starter-webflux:${springBootVersion}")
    compile('org.springframework.boot:spring-boot-starter-actuator')
    compile("org.springframework.data:spring-data-redis")
    compile('org.springframework.cloud:spring-cloud-starter-netflix-eureka-client')
    compile("org.jetbrains.kotlin:kotlin-stdlib-jdk8")
    compile("org.jetbrains.kotlin:kotlin-reflect")
    compile("com.fasterxml.jackson.module:jackson-module-kotlin:2.9.5")
    runtime('org.springframework.boot:spring-boot-devtools')
    testCompile('org.springframework.boot:spring-boot-starter-test')
}

谢谢

对于遇到相同问题的其他人，您需要单独添加 lettuce 依赖项。

compile("io.lettuce:lettuce-core:5.0.3.RELEASE")

还没有选择application.properties 稍后再解决。
