spring - Redis连接失败

Question

我想使用 Redis 来操作 session 。但是我在运行 spring boot 应用程序时失败了。所以我猜这个错误来自 maven 依赖项，尤其是版本冲突。

这是我的 maven 依赖项:

<dependencies>
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-data-jpa</artifactId>
    </dependency>
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-security</artifactId>
    </dependency>
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-web</artifactId>
    </dependency>

    <dependency>
        <groupId>mysql</groupId>
        <artifactId>mysql-connector-java</artifactId>
        <scope>runtime</scope>
    </dependency>
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-test</artifactId>
        <scope>test</scope>
    </dependency>
    <dependency>
        <groupId>org.springframework.security</groupId>
        <artifactId>spring-security-test</artifactId>
        <scope>test</scope>
    </dependency>

    <dependency>
        <groupId>org.springframework.session</groupId>
        <artifactId>spring-session-data-redis</artifactId>
        <version>1.7.0.RELEASE</version>
    </dependency>

    <dependency>
        <groupId>io.lettuce</groupId>
        <artifactId>lettuce-core</artifactId>
        <version>5.0.0.RELEASE</version>
    </dependency>
</dependencies>

请注意，我在上面的 pom.xml 中添加了两个依赖项，其中 artifactId 是 spring-session-data-redis 和 lettuce-core。这些依赖分别负责Redis的连接和保证session连接的线程安全。

当我运行 spring boot 应用程序时，出现以下错误:

---

应用程序启动失败

---

描述:

试图调用方法 org.springframework.data.redis.connection.RedisConnection.getConfig(Ljava/lang/String;)Ljava/util/List;但它不存在。它的类 org.springframework.data.redis.connection.RedisConnection 可从以下位置获得:

jar:file:/C:/Users/aoutir/.m2/repository/org/springframework/data/spring-data-redis/2.0.10.RELEASE/spring-data-redis-2.0.10.RELEASE.jar!/org/springframework/data/redis/connection/RedisConnection.class

它是从以下位置加载的:

文件:/C:/Users/aoutir/.m2/repository/org/springframework/data/spring-data-redis/2.0.10.RELEASE/spring-data-redis-2.0.10.RELEASE.jar

行动:

更正应用程序的类路径，使其包含 org.springframework.data.redis.connection.RedisConnection 的单个兼容版本

非常感谢任何帮助，提前感谢您的回复。

我花了一整天的时间来解决完全相同的问题。经过一整天的研发，我找到了解决方案。

dependencies {
implementation('org.springframework.boot:spring-boot-starter-data-jpa')
implementation('org.springframework.boot:spring-boot-starter-data-rest')
implementation('org.springframework.boot:spring-boot-starter-web')
implementation('org.springframework.boot:spring-boot-starter-security')
implementation('org.springframework.boot:spring-boot-starter-data-redis')
implementation('org.springframework.session:spring-session-data-redis')

runtimeOnly('org.springframework.boot:spring-boot-devtools')
testImplementation('org.springframework.boot:spring-boot-starter-test')
runtimeOnly('org.flywaydb:flyway-core')
runtimeOnly('com.h2database:h2')


// runtimeOnly('mysql:mysql-connector-java')

使用“spring-boot-starter-data-redis”和“spring-session-data-redis”。删除 lettuse 依赖项，因为它作为依赖项包含在 spring-boot-starter-data-redis 中。

这是你的依赖:
