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:
redis:
gisredis:
host: 10.142.142.142
port: 6379
database: 6
testOnBorrow: true
pool:
max-active: 10000
max-idle: 1000
max-wait: 60000
min-idle: 0
appredis:
host: 10.142.141.84
port: 6379
database: 5
testOnBorrow: true
pool:
max-active: 10000
max-idle: 1000
max-wait: 60000
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
@Autowired
@Qualifier("appredisStringRedisTemplate")
private StringRedisTemplate appredisStringRedisTemplate;
即可得到指定的redis源，使用起来也是很方便
