Spring boot配置多个Redis数据源操作实例

在SpringBoot是项目中整合了两个Redis的操作实例，可以增加多个；
一般在一个微服务生态群中是不会出现多个Redis中间件的，所以这种场景很少见，但也不可避免，但是不建议使用，个人建议，勿喷。

基于Maven3.0搭建，spring1.5.9.RELEASE和JDK1.8

1、新建SpringBoot项目，添加依赖

 <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-data-redis</artifactId> </dependency> <dependency> <groupId>org.projectlombok</groupId> <artifactId>lombok</artifactId> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-test</artifactId> <scope>test</scope> </dependency>

2、application.yml配置文件

spring: redis: database: 6

3、新建RedisConfig类

package com.lilian.config; import com.fasterxml.jackson.annotation.JsonAutoDetect; import com.fasterxml.jackson.annotation.PropertyAccessor; import com.fasterxml.jackson.databind.ObjectMapper; import org.springframework.beans.factory.annotation.Value; import org.springframework.cache.CacheManager; import org.springframework.cache.annotation.EnableCaching; import org.springframework.cache.interceptor.KeyGenerator; import org.springframework.context.annotation.Bean; import org.springframework.context.annotation.Configuration; import org.springframework.data.redis.cache.RedisCacheManager; import org.springframework.data.redis.connection.jedis.JedisConnectionFactory; import org.springframework.data.redis.core.RedisTemplate; import org.springframework.data.redis.serializer.Jackson2JsonRedisSerializer; import org.springframework.data.redis.serializer.StringRedisSerializer; import redis.clients.jedis.JedisPoolConfig; import java.lang.reflect.Method;

4、使用Java类注入多个数据源

数据源一

package com.lilian.config; import org.springframework.beans.factory.annotation.Value; import org.springframework.cache.annotation.EnableCaching; import org.springframework.context.annotation.Bean; import org.springframework.context.annotation.Configuration; import org.springframework.data.redis.connection.RedisConnectionFactory; import org.springframework.data.redis.core.RedisTemplate;

数据源二

package com.lilian.config; import org.springframework.beans.factory.annotation.Value; import org.springframework.cache.annotation.EnableCaching; import org.springframework.context.annotation.Bean; import org.springframework.context.annotation.Configuration; import org.springframework.context.annotation.Primary; import org.springframework.data.redis.connection.RedisConnectionFactory; import org.springframework.data.redis.core.RedisTemplate;

数据源三同理。。。

5、随便定义一个实体类

package com.lilian.entity; import lombok.AllArgsConstructor; import lombok.Data;

6、测试方法

package com.lilian; import com.lilian.entity.Person; import org.junit.Test; import org.junit.runner.RunWith; import org.springframework.boot.test.context.SpringBootTest; import org.springframework.data.redis.core.RedisTemplate; import org.springframework.test.context.junit4.SpringRunner; import javax.annotation.Resource;
