本文主要是介绍springboot整合spring-data-redis使用redisTemplate操作,希望对大家解决编程问题提供一定的参考价值,需要的开发者们随着小编来一起学习吧!
一.spring data redis的安装
1.1 安装gcc
安装命令为:yum install gcc-c++
[root@bogon ~]# yum install gcc-c++

1.2 解压redis的软件包
进入redis的存储目录:/bonc-kecheng-jingxiang ,进行解压
[root@bogon bonc-kecheng-jingxiang]# tar -zxvf redis-6.2.1.tar.gz
redis-6.2.1/
redis-6.2.1/.github/
redis-6.2.1/.github/ISSUE_TEMPLATE/

1.3 进入解压后的目录进行编译
进入redis的解压后的目录,然后执行:make PREFIX=/usr/local/redis install 进行编译
[root@bogon bonc-kecheng-jingxiang]# ls

[root@bogon bonc-kecheng-jingxiang]# cd redis-6.2.1/

1.4 启动redis
1.修改一下配置redis.conf配置文件的内容:
先进入到 redis-6.2.1目录下
[root@localhost redis-6.2.1]# vi redis.conf
[root@localhost redis-6.2.1]#
修改内容如下:
2.先进入到:/usr/local/redis/bin 这个目录下,然后执行启动脚本命令:
./redis-server /bonc-kecheng-jingxiang/redis-6.2.1/redis.conf
root@bogon redis-6.2.1]# cd /usr/local
[root@bogon local]# ls
bin etc games include lib lib64 libexec redis sbin share src
[root@bogon local]# cd redis
[root@bogon redis]# ls
bin
[root@bogon redis]# cd bin
[root@bogon bin]# ls
redis-benchmark redis-check-aof redis-check-rdb redis-cli redis-sentinel redis-server
[root@bogon bin]# ./redis-server /bonc-kecheng-jingxiang/redis-6.2.1/redis.conf

启动后的截图:
1.5 启动客户端进行查看
同样在打开一个新窗口,先进到/usr/local/redis/bin目录下,然后给执行: ./redis-cli
[root@192 ~]# cd /usr/local/redis
[root@192 redis]# bin
bash: bin: command not found...
[root@192 redis]# ls
bin
[root@192 redis]# cd bin
[root@192 bin]# ls
dump.rdb redis-check-aof redis-cli redis-server
redis-benchmark redis-check-rdb redis-sentinel
[root@192 bin]# ./redis-cli

二 springboot整合spring data redis
2.1 spring data redis的作用
spring data redis的作用是简化对redis的开发工作,属于spring data 下的一个模块。
工程结构:
2.2 pom文件
<dependencies><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-data-redis</artifactId></dependency><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-web</artifactId></dependency><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-test</artifactId><scope>test</scope></dependency><dependency><groupId>org.apache.commons</groupId><artifactId>commons-pool2</artifactId></dependency>
2.3 application配置文件
# Redis数据库索引(默认为0)
#spring.redis.database=0# Redis服务器地址
spring.redis.host=192.168.1.192# Redis服务器连接端口
spring.redis.port=6379# Redis服务器连接密码(默认为空)
#spring.redis.password=root# 连接池最大连接数(使用负值表示没有限制)
spring.redis.jedis.pool.max-active=8# 连接池最大阻塞等待时间(使用负值表示没有限制)
spring.redis.jedis.pool.max-wait=-1# 连接池中的最大空闲连接
spring.redis.jedis.pool.max-idle=8# 连接池中的最小空闲连接
spring.redis.jedis.pool.min-idle=0# 连接超时时间(毫秒)
spring.redis.timeout=1000000
2.4 redis连接池
package com.ljf.spring.boot.demo.config;import com.fasterxml.jackson.annotation.JsonAutoDetect;
import com.fasterxml.jackson.annotation.PropertyAccessor;
import com.fasterxml.jackson.databind.ObjectMapper;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.data.redis.connection.RedisConnectionFactory;
import org.springframework.data.redis.connection.RedisStandaloneConfiguration;
import org.springframework.data.redis.connection.jedis.JedisClientConfiguration;
import org.springframework.data.redis.connection.jedis.JedisConnectionFactory;
import org.springframework.data.redis.core.RedisTemplate;
import org.springframework.data.redis.serializer.Jackson2JsonRedisSerializer;
import org.springframework.data.redis.serializer.StringRedisSerializer;/*** 完成对Redis的整合的一些配置***/
@Configuration
public class RedisConfig {@Beanpublic RedisTemplate<Object, Object> redisTemplate(RedisConnectionFactory redisConnectionFactory) {RedisTemplate<Object, Object> redisTemplate = new RedisTemplate<>();redisTemplate.setConnectionFactory(redisConnectionFactory);// 使用Jackson2JsonRedisSerialize 替换默认序列化Jackson2JsonRedisSerializer jackson2JsonRedisSerializer = new Jackson2JsonRedisSerializer(Object.class);ObjectMapper objectMapper = new ObjectMapper();objectMapper.setVisibility(PropertyAccessor.ALL, JsonAutoDetect.Visibility.ANY);objectMapper.enableDefaultTyping(ObjectMapper.DefaultTyping.NON_FINAL);jackson2JsonRedisSerializer.setObjectMapper(objectMapper);// 设置value的序列化规则和 key的序列化规则redisTemplate.setValueSerializer(jackson2JsonRedisSerializer);redisTemplate.setKeySerializer(new StringRedisSerializer());redisTemplate.afterPropertiesSet();return redisTemplate;}
}
2.5 controller
package com.ljf.spring.boot.demo.controller;import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.data.redis.core.RedisTemplate;
import org.springframework.data.redis.core.StringRedisTemplate;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestBody;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.ResponseBody;/*** @ClassName: RedisController* @Description: TODO* @Author: liujianfu* @Date: 2021/03/14 20:59:26 * @Version: V1.0**/
@Controller
public class RedisController {@Autowiredprivate StringRedisTemplate stringRedisTemplate;@Autowiredprivate RedisTemplate redisTemplate;/*** 添加一个字符串*/@RequestMapping("/add")@ResponseBodypublic String testSet(){this.redisTemplate.opsForValue().set("key", "中国人民ruc");System.out.println("add=====");return "ok";}/*** 获取一个字符串*/@RequestMapping("/get")@ResponseBodypublic String testGet(){String value = (String)this.redisTemplate.opsForValue().get("key");System.out.println(value);return value;}
