如何使用 spring-data-redis 连接到多个 redis 实例 [英] How to connect to multiple redis instances with spring-data-redis

问题描述

我正在尝试将一个 springboot 应用程序连接到 2 个不同的 redis 实例:一个用作数据库，一个仅用作缓存.我添加了不同名称的不同连接工厂和 redis 模板，我正在使用 @Qualifier 来链接它们.我试图从自动配置中禁用类 RedisAutoConfiguration，但没有任何效果.

I'm trying to connect with one springboot application to 2 different redis instances: one used as database and one used as cache only. I added different connection factories and redis templates with different names and I'm using @Qualifier to link them. I tried to disable from auto configuration the class RedisAutoConfiguration, but nothing works.

我总是收到这个错误:

Wrapped by: org.springframework.beans.factory.UnsatisfiedDependencyException: 在类路径资源 [org/springframework/boot/autoconfigure/data/redis/RedisAutoConfiguration$RedisConfiguration.class] 中定义名称为redisTemplate"的 bean 创建时出错:不满意通过构造函数参数表示的依赖关系为 [org.springframework.data.redis.connection.RedisConnectionFactory] ​​类型的索引 0:没有定义 [org.springframework.data.redis.connection.RedisConnectionFactory] ​​类型的合格 bean:预期的单个匹配 bean 但发现 2: redisCacheFactory,redisJitFactory;嵌套异常是 org.springframework.beans.factory.NoUniqueBeanDefinitionException:没有定义 [org.springframework.data.redis.connection.RedisConnectionFactory] ​​类型的合格 bean:预期的单个匹配 bean 但找到 2:redisCacheFactory,redisJitFactory

Wrapped by: org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'redisTemplate' defined in class path resource [org/springframework/boot/autoconfigure/data/redis/RedisAutoConfiguration$RedisConfiguration.class]: Unsatisfied dependency expressed through constructor argument with index 0 of type [org.springframework.data.redis.connection.RedisConnectionFactory]: No qualifying bean of type [org.springframework.data.redis.connection.RedisConnectionFactory] is defined: expected single matching bean but found 2: redisCacheFactory,redisJitFactory; nested exception is org.springframework.beans.factory.NoUniqueBeanDefinitionException: No qualifying bean of type [org.springframework.data.redis.connection.RedisConnectionFactory] is defined: expected single matching bean but found 2: redisCacheFactory,redisJitFactory

您能否就如何实现这一点给我任何提示?

Can you give me any hint on how is possible to implement this?

提前致谢！

推荐答案

问题是将 connectionFactory 提取为 bean.如果在模板 bean 中声明它可以正常工作.以下对我有用:

The problem is extracting the connectionFactory as beans. If you declare it inside template bean works properly. The following works for me:

<bean id="redisTemplate" class="org.springframework.data.redis.core.RedisTemplate"
    p:defaultSerializer-ref="stringRedisSerializer">
    <property name="connectionFactory">
       <bean class="org.springframework.data.redis.connection.jedis.JedisConnectionFactory"
        p:host-name="${redis.ip}" p:port="6379" p:use-pool="true"/>
    </property>
</bean> 

<bean id="redisTemplate2" class="org.springframework.data.redis.core.RedisTemplate"
    p:defaultSerializer-ref="stringRedisSerializer">
    <property name="connectionFactory">
       <bean class="org.springframework.data.redis.connection.jedis.JedisConnectionFactory"
        p:host-name="${redis.ip2}" p:port="6379" p:use-pool="true"/>
    </property>
</bean> 

    <bean id="stringRedisSerializer"  class="org.springframework.data.redis.serializer.StringRedisSerializer"/>
