# Redis动态数据源

### 基于Lettuce客户端实现Redis多数据源配置

参考：https://zhuanlan.zhihu.com/p/405242915

Tips：原文中LettuceConnectionConfiguration类在3.2.3版本中不是public，外包无法访问，
所以对相关类进行的重写。

基于 spring-boot-starter-data-redis:3.2.3 

### 用例
pom
```xml
<dependency>
    <groupId>org.facelay</groupId>
    <artifactId>redis-dynamic-datasource</artifactId>
    <version>latest.version</version>
</dependency>
```
application.yaml
```yaml
spring:
  data:
    enable-multi-redis: true   # 开启多数据源配置
    multi-redis:
      default:                 # 默认数据源节点，必须为default 
        host: 127.0.0.1
        port: 6379
        password: 123456
        database: 1
      source2:                 # 其它数据源节点，名字随意
        host: 127.0.0.1
        port: 6379
        password: 123456
        database: 2
      source3:
        host: 127.0.0.1
        port: 6379
        password: 123456
        database: 3
```
case
```java
    @Resource
    private RedisTemplate<String, Object> redisTemplate;

    @Resource
    private MultiRedisConnectionFactory redisConnectionFactory;

    /**
     * 操作指定的数据源的指定db
     */
    @GetMapping("/multiRedis")
    public String multiRedis() {
        redisTemplate.opsForValue().set("k1", "k1", 5, TimeUnit.MINUTES);

        redisConnectionFactory.setCurrentRedis("source2");
        redisTemplate.opsForValue().set("k2", "k2", 6, TimeUnit.MINUTES);

        redisConnectionFactory.setCurrentRedis("source3");
        redisTemplate.opsForValue().set("k3", "k3", 7, TimeUnit.MINUTES);

        return "success";
    }
```
