无法获得redisTemplate for Spring数据redis的连接

Question

我正在尝试使用Jedis使用Spring数据Redis将消息发布到通道。这是一个非常简单的Java配置：

@Bean(name="jedisConnectionFactory")
JedisConnectionFactory jedisConnectionFactory() {
    JedisConnectionFactory factory = new JedisConnectionFactory();
    factory.setHostName(redisHostName);
    factory.setPort(redisPort);
    factory.setUsePool(true);
    return factory;
}

@Bean(name="redisTemplate")
RedisTemplate<Object, Object> redisTemplate() {
    RedisTemplate<Object, Object> redisTemplate = new RedisTemplate<Object, Object>();
    redisTemplate.setConnectionFactory(jedisConnectionFactory());
    return redisTemplate;
}

其中redisPort = 6379，redisHostName =“localhost”。

当我运行以下测试时：

 @Test
public void testRedis(){
    ApplicationContext context = new AnnotationConfigApplicationContext(AppConfig.class);
    RedisTemplate<Object,Object> redisTemplate = (RedisTemplate<Object, Object>) context.getBean("redisTemplate");
    redisTemplate.convertAndSend("test", "123");
}

我得到以下stacktrace：

Answer 1

此问题是由Jedis版本（2.7.2）与Spring Data Redis（1.5.0.RELEASE）不兼容引起的。在我受到这篇文章和评论的启发之前，我用了3天面对同样的问题。 Jedis版本（2.6.2）工作正常（虽然我在我的程序中遇到了其他错误，但至少它有一些进展而不是相同的错误消息）！

谢谢。

Answer 2

您可以在以下链接中找到与jedis maven版本兼容的spring data maven版本：https://mvnrepository.com/artifact/org.springframework.boot/spring-boot-starter-data-redis/1.5.9.RELEASE

Answer 3

事实证明我使用的是Jedis 2.7.2，但Spring Data Redis 1.5.0似乎与Jedis 2.6.2兼容。我希望文档在某种程度上更加清晰。

Answer 4

兼容版本：

<dependency>
    <groupId>redis.clients</groupId>
    <artifactId>jedis</artifactId>
    <version>2.7.0</version>
</dependency>
<dependency>
    <groupId>org.springframework.data</groupId>
    <artifactId>spring-data-redis</artifactId>
    <version>1.5.0.RELEASE</version>
</dependency>

Answer 5

我也遇到过类似的问题。我做了一些研究，发现它是由于罐子冲突造成的。

我在我的应用程序中使用的兼容版本是：

<dependency>
    <groupId>org.springframework.data</groupId>
    <artifactId>spring-data-redis</artifactId>
    <version>1.8.10.RELEASE</version>
</dependency>
<dependency>
    <groupId>redis.clients</groupId>
    <artifactId>jedis</artifactId>
    <version>2.9.0</version>
</dependency>

或者，如果您使用的是spring boot，只需添加以下依赖项。 Spring启动足够聪明，可以自动解决此类问题。

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-data-redis</artifactId>
</dependency>

我希望它有所帮助!!

Answer 7

Navin Viswanath，谢谢你的解决方案！你是如何使用文档或调试找到它的？

对于那些使用Gradle的人来说，这是我的组合：

版本：

• Redis 3.0.2
• 杰迪斯2.7.2
• Spring Data Redis 1.6.0 M1（在maven中心不可用，因为它是里程碑版本 - 添加http://repo.spring.io/milestone/ repo）

的build.gradle：

repositories {
  mavenCentral()
  maven { url 'http://repo.spring.io/release/' }
  maven { url 'http://repo.spring.io/milestone/' }
}

dependencies {
  compile group: 'redis.clients', name: 'jedis', version: '2.7.2'
  compile group: 'org.springframework.data', name: 'spring-data-redis', version: '1.6.0.M1'
}

请注意，Spring Data Redis 1.6.0.M1一旦发布就会被删除，你需要在发布时将其更改为1.6.0.RELEASE。

所以，我在这里检查版本兼容性：https://github.com/spring-projects/spring-data-redis/blob/master/gradle.properties并在此处找到相关的JIRA票：https://jira.spring.io/browse/DATAREDIS-396

Answer 8

与spring-boot-starter-data-redis 2.0.4有类似的问题

当我隐式地将依赖项放在应用程序pom.xml中的jedis时它以某种方式工作

    <dependency>
        <groupId>redis.clients</groupId>
        <artifactId>jedis</artifactId>
        <version>2.9.0</version>
    </dependency>

eclipse抱怨“复制托管版本”，但其他一切都有效

Answer 9

对于那些使用Spring-boot-starter-data-redis的人

可以按如下方式输入永久性修复：

1. 确定spring-boot-starter-data-redis的版本。在eclipse中，您可以将鼠标悬停在pom.xml文件中的依赖项条目上。它会告诉您正在使用的版本。
2. 导航到maven存储库中的该版本目录。
3. 编辑pom文件并添加所需的redis客户端版本号。在这种情况下，版本2.6.2.RELEASE与spring-boot-starter-data-redis的1.50版本一起使用。在这种情况下，我不得不添加<version>2.6.2.RELEASE</version。
4. 在IDE中，刷新整个项目。要在eclipse或STS中执行此操作，请单击项目名称 - >右键单击选择maven-> Update Project
5. 检查你的maven依赖列表，jedis版本现在应该是2.6.2。
6. 编译您的项目。
7. 使用jar或7-zip等打开.war存档。在WEB-INF下找到lib目录并验证是否存在jedis-2.6.2。

那应该解决这个问题。

Answer 10
