<!-- redis --> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-data-redis</artifactId> </dependency> <!-- spring2.X集成redis所需common-pool2--> <dependency> <groupId>org.apache.commons</groupId> <artifactId>commons-pool2</artifactId> <version>2.6.0</version> </dependency>springboot2.0版本默认应用lettuce连接池，默认不应用，只有在配置文件中应用连接池配置才开启，连接池须要依赖commons-pools2的依赖。
