spring 整合redis

1. 引用依赖

<!--Redis-->
<dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-data-redis</artifactId>
</dependency>

2.添加配置文件信息

server:port: 8603# DATABASE CONFIGdatasource:username: rootpassword: rooturl: jdbc:mysql://localhost:3306/moon?useUnicode=true&characterEncoding=utf-8&zeroDateTimeBehavior=convertToNull&transformedBitIsBoolean=true&useSSL=false&serverTimezone=Asia/Shanghaidriver-class-name: com.mysql.cj.jdbc.Drivertype: com.alibaba.druid.pool.DruidDataSource# 初始化大小，最小，最大initialSize: 5minIdle: 5maxActive: 50#连接等待超时时间maxWait: 60000#配置隔多久进行一次检测(检测可以关闭的空闲连接)timeBetweenEvictionRunsMillis: 60000#配置连接在池中的最小生存时间minEvictableIdleTimeMillis: 300000dbcp:remove-abandoned: true#泄露的连接可以被删除的超时时间（秒），该值应设置为应用程序查询可能执行的最长时间remove-abandoned-timeout: 180testWhileIdle: truetestOnBorrow: falsetestOnReturn: falsepoolPreparedStatements: true#配置监控统计拦截的filters，去掉后监控界面sql无法统计，'wall'用于防火墙filters: stat,wall,log4jmaxPoolPreparedStatementPerConnectionSize: 20useGlobalDataSourceStat: trueconnectionProperties: druid.stat.mergeSql=true;druid.stat.slowSqlMillis=500#mybatis

#redisredis:host: 127.0.0.1 #redis的主机ipport: 6379#password: mogu2018  # 客户端没有设置密码，服务器中redis默认密码为 mogu2018

这时就可以使用 org.springframework.data.redis.core.RedisTemplate; 包了

乱码问题解决

乱码问题描述

但是这时使用org.springframework.data.redis.core.RedisTemplate 包set key 时，会出现下图中的乱码错误。

乱码错误提示：can not load key value key was removed or redis-server went away

解决方法

这时可以配置redis 配置文件，随便在一个目录上加这个java 文件都行。
