springboot redis多数据源

springboot中默认的redis配置是只能对单个redis库进行操作的。

那么我们需要多个库操作的时候这个时候就可以采用redis多数据源。

本代码参考RedisAutoConfiguration源码进行整改成的多数据源配置

注意：数据源2就是数据源1copy了一份代码，把所有的gisredis改成appredis，并去除数据源2的@Primary即可。如果还需要增加多个数据源，以此类推

配置redis数据源1：

redis数据源1和数据源2的配置yml

   spring:

 1   redis:
 2     gisredis:
 3       host: 10.142.142.142
 4       port: 6379
 5       database: 6
 6       testOnBorrow: true
 7       pool:
 8         max-active: 10000
 9         max-idle: 1000
10         max-wait: 60000
11         min-idle: 0
12     appredis:
13       host: 10.142.141.84
14       port: 6379
15       database: 5
16       testOnBorrow: true
17       pool:
18         max-active: 10000
19         max-idle: 1000
20         max-wait: 60000
21         min-idle: 0

配置就这么多，要注意的是多个redis数据源必须指定一个默认的数据源。使用@Primary来指定，并且只能指定一个默认redis数据源。

注意：数据源2就是数据源1copy了一份代码，把所有的gisredis改成appredis，并去除数据源2的@Primary即可。如果还需要增加多个数据源，以此类推

最后在使用的时候

1 @Autowired
2 @Qualifier("appredisStringRedisTemplate")
3 private StringRedisTemplate appredisStringRedisTemplate;

即可得到指定的redis源，使用起来也是很方便
