写在前面：本文将使用的是redis单节点docker环境，如需redis集群环境请移步至https://blog.csdn.net/belonghuang157405/article/details/80934743

一、搭建redis环境

拉取镜像并启动redis容器

docker pull redis
docker run -d -p 6379:6379 --name redis-single redis

二、springboot集成redis

2.application.yml

spring:
redis:
host: 192.168.9.219
port: 6379
jedis:
pool:
max-active: 100
max-idle: 10
max-wait: -1ms
min-idle: 5
password:

3.User.java

public class User {

private Integer id;

private String name;

private int age;

public Integer getId() {
return id;
}

public void setId(Integer id) {
this.id = id;
}

public String getName() {
return name;
}

public void setName(String name) {
this.name = name;
}

public int getAge() {
return age;
}

public void setAge(int age) {
this.age = age;
}
}

4.RedisConfig.java

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.Jackson2JsonRedisSerializer;
import java.net.UnknownHostException;

@Configuration
public class RedisConfig {

/**
* 重新设置redis序列化 采用json格式 默认采用的是jdk序列化
* @param redisConnectionFactory
* @return
* @throws UnknownHostException
*/
@Bean
public RedisTemplate<Object, Object> redisTemplate(RedisConnectionFactory redisConnectionFactory) throws UnknownHostException {
RedisTemplate<Object, Object> template = new RedisTemplate();
Jackson2JsonRedisSerializer<Object> jackson2JsonRedisSerializer = new Jackson2JsonRedisSerializer<Object>(
Object.class);
template.setDefaultSerializer(jackson2JsonRedisSerializer);
template.setConnectionFactory(redisConnectionFactory);
return template;
}

}

5.测试类

import com.example.redis.po.User;
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.data.redis.core.StringRedisTemplate;
import org.springframework.test.context.junit4.SpringRunner;

@RunWith(SpringRunner.class)
@SpringBootTest
public class RedisApplicationTests {

/**
* 操作key-value都是字符串
*/
@Autowired
StringRedisTemplate stringRedisTemplate;

/**
* 操作key-value都是对象
*/
@Autowired
RedisTemplate redisTemplate;

/**
* 自定义序列后的RedisTemplate
*/
@Autowired
RedisTemplate<Object, Object> newRedisTemplate;

/**
* 测试保存
* redis常见数据类型：string-字符串  list-列表 set-集合 hash-散列 zset-有序集合
* stringRedisTemplate.opsForValue() 操作字符串
* stringRedisTemplate.opsForList() 操作列表
* stringRedisTemplate.opsForSet() 操作集合
* stringRedisTemplate.opsForHash() 操作散列
* stringRedisTemplate.opsForZet() 操作有序集合
*/
@Test
public void testSave() {
stringRedisTemplate.opsForValue().append("token","123");
}

/**
* 测试读取
*/
@Test
public void testRead() {
String token = stringRedisTemplate.opsForValue().get("token");
System.out.println(token);
}

/**
* 自定序列化redisTemplate 写入
*/
@Test
public void testNewSave(){
User user = new User();
user.setId(1);
user.setName("jack");
user.setAge(20);
newRedisTemplate.opsForValue().set("user-one",user);

}

/**
* 自定序列化redisTemplate 读取
*/
@Test
public void testNewRead() {
String token = newRedisTemplate.opsForValue().get("user-one").toString();
System.out.println(token);
}
}

其他数据类型请读者自行查看api进行测试。
