创建名为“…RedishttpsessionConfiguration”的bean时出错：bean初始化失败

Question

@EnableRedisHttpSession
public class HttpSessionConfig {

    @Bean
    public LettuceConnectionFactory connectionFactory() {

        return new LettuceConnectionFactory();
    }

    @Bean
    public HttpSessionIdResolver httpSessionStrategy() {
        return HeaderHttpSessionIdResolver.authenticationInfo();
    }

}

下面是我的pom.xml文件：

    <!-- Redis -->
    <dependency>
        <groupId>org.springframework.session</groupId>
        <artifactId>spring-session-data-redis</artifactId>
    </dependency>

    <dependency>
        <groupId>biz.paluch.redis</groupId>
        <artifactId>lettuce</artifactId>
        <version>4.3.1.Final</version>
    </dependency>

Error creating bean with name 'org.springframework.session.data.redis.config.annotation.web.http.RedisHttpSessionConfiguration':

bean初始化失败

有人知道怎么修吗？？？

在堆栈跟踪中，错误告诉

noClassDefoundError：io/lettuce/core/keyvalue

因此在pom.xml中手动添加依赖项io.lettuce

<dependency>
    <groupId>io.lettuce</groupId>
    <artifactId>lettuce-core</artifactId>
    <version>5.1.7.RELEASE</version>
</dependency>
