SpringBoot整合Redis 并 展示使用方法

步骤

1. 引入依赖
2. 配置数据库参数
3. 编写配置类
4. 构造RedisTemplate
5. 创建测试类测试

1.引入依赖

不写版本号，也是可以的

在pom中引入

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

2.配置数据库参数

在SpringBoot的yaml配置文件中引入，如果你用的是properties格式，那么去转换一下就行了，把yaml转换成properties

spring:redis:# Redis数据库索引（默认为0）database: 11# Redis服务器地址host: localhost# Redis服务器连接端口port: 6379# Redis服务器连接密码（默认为空）password: ''# 连接超时时间（毫秒）timeout: 1000

3.编写配置类

package com.kyw.config;import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.data.redis.connection.RedisConnectionFactory;
import org.springframework.data.redis.core.RedisTemplate;
import org.springframework.data.redis.serializer.RedisSerializer;@Configuration
public class RedisConfig {@Beanpublic RedisTemplate<String,Object> redisTemplate(RedisConnectionFactory factory) {RedisTemplate<String,Object> template = new RedisTemplate<>();template.setConnectionFactory(factory);// 设置key的序列化方式template.setKeySerializer(RedisSerializer.string());// 设置value的序列化方式template.setValueSerializer(RedisSerializer.json());// 设置hash的key序列化方式template.setHashKeySerializer(RedisSerializer.string());// 设置hash的value序列化方式template.setHashValueSerializer(RedisSerializer.json());// 在设置完参数后生效template.afterPropertiesSet();return template;}}

4.构造RedisTemplate

上面的配置类中就构造好了

5.测试

这里用的是junit测试，是常用的测试工具，没有导入的小伙伴导入一下，网上搜一下很简单。

编写测试类

import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.data.redis.core.RedisTemplate;
import org.springframework.test.context.ContextConfiguration;
import org.springframework.test.context.junit4.SpringRunner;@RunWith(SpringRunner.class)
@SpringBootTest
//下面括号里面：classes  = SpringBootDemoApplication.class，如果报错，那你转换成自己的SpringBoot启动类的类名就行
@ContextConfiguration(classes  = SpringBootDemoApplication.class)
public class RedisTest {@Autowiredprivate RedisTemplate redisTemplate;}

测试String

/***String 测试*/
@Test
public void testStrings(){String redisKey = "test:count";//设置一个 key valueredisTemplate.opsForValue().set(redisKey,1);//获取valueSystem.out.println(redisTemplate.opsForValue().get(redisKey));//value自增System.out.println(redisTemplate.opsForValue().increment(redisKey));//value自减System.out.println(redisTemplate.opsForValue().decrement(redisKey));
}

测试哈希

/***哈希 测试*/
@Test
public void testHashes(){String redisKey = "test:user";redisTemplate.opsForHash().put(redisKey,"id",1);redisTemplate.opsForHash().put(redisKey,"username","张三");System.out.println(redisTemplate.opsForHash().get(redisKey,"id"));System.out.println(redisTemplate.opsForHash().get(redisKey,"username"));
}

 

测试list

/***list 类测试*/
@Test
public void testLists(){String redisKey = "test:ids";redisTemplate.opsForList().leftPush(redisKey,101);redisTemplate.opsForList().leftPush(redisKey,102);redisTemplate.opsForList().leftPush(redisKey,103);System.out.println(redisTemplate.opsForList().size(redisKey));System.out.println(redisTemplate.opsForList().index(redisKey,0));System.out.println(redisTemplate.opsForList().range(redisKey,0,2));System.out.println(redisTemplate.opsForList().leftPop(redisKey));System.out.println(redisTemplate.opsForList().leftPop(redisKey));System.out.println(redisTemplate.opsForList().leftPop(redisKey));}

 测试set

/***set 测试*/
@Test
public void testSets(){String redisKey = "test:teachers";redisTemplate.opsForSet().add(redisKey,"鸣人","路飞","韩立","炭治郎","祖国人");System.out.println(redisTemplate.opsForSet().size(redisKey));System.out.println(redisTemplate.opsForSet().pop(redisKey));System.out.println(redisTemplate.opsForSet().pop(redisKey));}

 

 测试zset

@Test
public void testSortSets(){String redisKey = "test:students";redisTemplate.opsForZSet().add(redisKey,"少年鸣人",10);redisTemplate.opsForZSet().add(redisKey,"仙人鸣人",60);redisTemplate.opsForZSet().add(redisKey,"九尾鸣人",70);redisTemplate.opsForZSet().add(redisKey,"九喇嘛联结鸣人",80);redisTemplate.opsForZSet().add(redisKey,"六道鸣人",90);System.out.println(redisTemplate.opsForZSet().zCard(redisKey));System.out.println(redisTemplate.opsForZSet().score(redisKey,"六道鸣人"));System.out.println(redisTemplate.opsForZSet().reverseRank(redisKey,"六道鸣人"));System.out.println(redisTemplate.opsForZSet().range(redisKey,0,4));System.out.println(redisTemplate.opsForZSet().removeRange(redisKey,0,2));}

 测试通用操作

/***测试通用操作*/
@Test
public void testKeys(){redisTemplate.delete("test:user");System.out.println(redisTemplate.hasKey("test:user"));redisTemplate.expire("text:students",10, TimeUnit.SECONDS);
}

测试绑定key到变量的操作

/***测试 绑定一个key 的操作*/
@Test
public void testBondOperations(){String redisKey = "test:count";//用 BoundValueOperations 将一个key绑定到对象上，方便后面的操作//绑定的是 String 那就 BoundValueOperations，是set 那就BoundSetOperations,其余同理BoundValueOperations operations = redisTemplate.boundValueOps(redisKey);System.out.println(operations.get());operations.increment();operations.increment();System.out.println(operations.get());}
