springboot整合redis（单台）

首先确保自己已经成功安装redis不管是win的还是linux的！

windows 下载地址

http://files.cnblogs.com/files/cuiwenyuan/Redis-3.2.100-Windows-32.zip

https://github.com/ServiceStack/redis-windows

下载完之后解压即可

解压后目录

springboot整合redis（单台）

启动命令：redis-servier

打开cmd:

springboot整合redis（单台）

然后再打开一个cmd 用来打开客户端，命令 redis-cli，存储一个key value 值测试一下。

出现上面两个图说明windows 下 redis安装成功。

linux版的直接去官网下载即可

http://redis.io/download

也可以通过命令下载 wget http://download.redis.io/releases/redis-2.8.3.tar.gz

这里推荐一个博客安装教程 https://www.cnblogs.com/codersay/p/4301677.html 可以参考这位大牛的，简单粗暴。

安装完之后成功启动之后：

在springboot 的application.properties 文件中添加配置

################# redis\u57FA\u7840\u914D\u7F6E #################
spring.redis.host=192.168.1.116
#spring.redis.password=root
spring.redis.port=6379
#spring.redis.timeout=3000

添加依赖

<dependency>
           <groupId>org.springframework.boot</groupId>
           <artifactId>spring-boot-starter-redis</artifactId>
           <version>1.4.7.RELEASE</version>
       </dependency>

主方法中添加注解，表示开启缓存

在实现类中设置缓存

controller

controller中调用后页面显示结果

我这里返回json数据

若出现以下错误

2018-07-18 22:41:32.506 ERROR 6120 --- [nio-8080-exec-1] o.a.c.c.C.[.[.[/].[dispatcherServlet] : Servlet.service() for servlet [dispatcherServlet] in context with path [] threw exception [Request processing failed; nested exception is org.springframework.data.redis.serializer.SerializationException: Cannot deserialize; nested exception is org.springframework.core.serializer.support.SerializationFailedException: Failed to deserialize payload.

   at java.io.ObjectInputStream.readObject(ObjectInputStream.java:371) ~[na:1.8.0_66]

则说明实体类未实现序列化接口 实现后即可成功显示
