SpringBoot項目，配置Redis多數據源

一、maven依賴

Springboot版本: 1.5.6.RELEASE
<!--redis-->
<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-data-redis</artifactId>
</dependency>
<!--多數據源-->
<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-configuration-processor</artifactId>
    <optional>true</optional>
</dependency>

二、redis配置文件

2.1 application.yml

spring:
  redis:
    host: xxx.xxx.xxx.xxx
    port: xxxx
    timeout: 0
    pool:
      max-active: 8
      max-wait: -1
      max-idle: 8
      min-idle: 0
  redis2:
    host: xxx.xxx.xxx.xxx
    port: xxxx
    timeout: 0
