Question

我正在尝试使用Jedis使用Spring数据Redis将消息发布到频道。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）运行正常（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）！

感谢。

Answer 2

原来我使用的是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 3

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

Navin Viswanath，谢谢您的解决方案！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：

<强>版本：

Redis 3.0.2
Jedis 2.7.2
Spring Data Redis 1.6.0 M1（在maven central中不可用，因为它的里程碑版本 - 添加http://repo.spring.io/milestone/ repo）

<强>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，您需要在发布时将其更改为1.6.0.RELEASE。

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

Answer 6

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 spring boot ，只需添加以下依赖项。 Spring boot非常智能，可以自动解决这些问题。

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

我希望它有所帮助!!

Answer 7

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

当我在pom.xml应用程序中将jedis隐式依赖项以某种方式起作用时

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

eclipse抱怨“复制受管版本”，但其他所有方法都起作用

Answer 8

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：

确定spring-boot-starter-data-redis的版本。在 eclipse，你可以将鼠标悬停在pom.xml中的依赖项上文件。它会告诉你你正在使用的版本。
导航到maven存储库中的该版本目录。
编辑pom文件并添加所需的redis客户端版本号。在本例中，版本为2.6.2.RELEASE 1.50 of spring-boot-starter-data-redis。在这种情况下，我必须添加<version>2.6.2.RELEASE</version。
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-＆gt;更新项目
检查你的maven依赖列表，jedis版本现在应该是2.6.2。
编译项目。
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。

这应解决问题。

Answer 9

兼容版本：

<dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-data-redis</artifactId>
        <version>2.0.4.RELEASE</version>
    </dependency>
    <dependency>
        <groupId>redis.clients</groupId>
        <artifactId>jedis</artifactId>
        <version>2.9.0</version>
</dependency>

Answer 10

您可以从下面的波纹管链接https://mvnrepository.com/artifact/org.springframework.boot/spring-boot-starter-data-redis/1.5.9.RELEASE

中找到与jedis maven版本兼容的spring数据maven版本。

Answer 11

自 2019 年 7 月起，Spring Boot 2.X 与 Jedis 3.X 兼容（有关详细信息，请参阅 Upgrade to Jedis 3.1.0）。对于使用Gradle的人，示例如下：

build.gradle

plugins {
    id 'org.springframework.boot' version '2.3.2.RELEASE'
    id 'io.spring.dependency-management' version '1.0.8.RELEASE'
    id 'java'
}

group = 'com.example'
version = '0.0.1-SNAPSHOT'
sourceCompatibility = '1.8'

repositories {
    mavenCentral()
}

dependencies {
    implementation 'org.springframework.boot:spring-boot-starter-data-redis'
    implementation 'redis.clients:jedis:3.1.0'
}

无法获得redisTemplate for Spring数据redis的连接
