有关Springboot+redis的配置和使用，完整篇。git
此配置，几乎能够无脑的粘贴进项目中使用。github
springboot项目的建立能够参考以前：https://www.jianshu.com/p/b9f066a221b0web
本篇测试项目github地址：https://github.com/zhengjiaao/springboot-test-redisredis
1.在springboot项目的pom.xml
文件里加入redis的jar依赖spring
<parent> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-parent</artifactId> <version>2.0.5.RELEASE</version> <relativePath/> <!-- lookup parent from repository --> </parent> <dependencies> <!--======== SpringBoot的配置start ===========--> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-web</artifactId> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-tomcat</artifactId> <scope>provided</scope> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-test</artifactId> <scope>test</scope> </dependency> <!-- hibernate jpa--> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-data-jpa</artifactId> </dependency> <!--简单快速的访问静态资源(图片、html等)--> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-thymeleaf</artifactId> </dependency> <!--开发阶段使用：springboot热启动(热部署)：项目有更改，自动编译：需配置idea true生效--> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-devtools</artifactId> <optional>true</optional> </dependency> <!--======= SpringBoot的配置end =========--> <!--springboot中的redis依赖--> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-data-redis</artifactId> </dependency> </dependencies>
2.目录结构：redis用到的类

3.在application.yml中配置redis参数

4.redis的配置类
RedisConfig.java类json
