点击上面 Spring Data Redis
https://github.com/spring-projects/spring-data-redis
可以在README中查看需要的内容，比如：
SpringBoot整合Spring Data Redis
添加pom依赖
org.springframework.boot
spring-boot-starter-data-redis
redis自动配置类：RedisAutoConfiguration
属性配置类RedisProperties
@ConfigurationProperties(prefix = "spring.redis")
public class RedisProperties {
/**
* Database index used by the connection factory.
*/
private int database = 0;
/**
* Connection URL. Overrides host, port, and password. User is ignored. Example:
* redis://user:[email protected]:6379
*/
private String url;
/**
* Redis server host.
*/
private String host = "localhost";
/**
* Login username of the redis server.
*/
private String username;
/**
* Login password of the redis server.
*/
private String password;
/**
* Redis server port.
*/
private int port = 6379;
/**
* Whether to enable SSL support.
*/
private boolean ssl;
/**
* Read timeout.
*/
private Duration timeout;
/**
* Connection timeout.
*/
private Duration connectTimeout;
/**
* Client name to be set on connections with CLIENT SETNAME.
*/
private String clientName;
/**
* Type of client to use. By default, auto-detected according to the classpath.
*/
private ClientType clientType;
private Sentinel sentinel;
private Cluster cluster;
private final Jedis jedis = new Jedis();
private final Lettuce lettuce = new Lettuce();
......
我们的配置文件application.properties中可以配置redis，以spring.redis开头
# 服务器ip
spring.redis.host=116.10.53.66
# 端口
spring.redis.port=6379
# 密码
spring.redis.password=tester
# 第一个数据库存储
spring.redis.database=0
# 最大活跃数
spring.redis.jedis.pool.max-active=20
# 最大空闲数
spring.redis.jedis.pool.max-idle=10
# 最小空闲数
spring.redis.jedis.pool.min-idle=5
使用redisTemplate
操作字符串
key和value都不设置序列化器
package com.qzcsbj.demo;
import org.junit.jupiter.api.Test;
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;
/**
* @公众号 : 全栈测试笔记
* @博客 : www.cnblogs.com/uncleyong
* @微信 : ren168632201
* @描述 : <>
*/
@SpringBootTest
public class MyTest {
@Autowired
private StringRedisTemplate stringRedisTemplate;
@Autowired
private RedisTemplate redisTemplate;
@Test
public void test1(){
redisTemplate.opsForValue().set("name","jack");
System.out.println("set字符串完成。");
Object name = redisTemplate.opsForValue().get("name");
System.out.println("获取到的name: " + name);
}
}
代码中正常获取
但是redis客户端不行
给key和value设置序列化器
package com.qzcsbj.demo;
import org.junit.jupiter.api.Test;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.data.redis.core.RedisTemplate;

/**

*/
@SpringBootTest
public class MyTest {
@Autowired
private StringRedisTemplate stringRedisTemplate;
@Autowired
private RedisTemplate redisTemplate;
@Test
public void test1(){
// 为key设置序列化器
redisTemplate.setKeySerializer(new StringRedisSerializer());
// 为value设置序列化器
redisTemplate.setValueSerializer(new StringRedisSerializer());
redisTemplate.opsForValue().set("name","jack");
System.out.println("set字符串完成。");
Object name = redisTemplate.opsForValue().get("name");
System.out.println("获取到的name: " + name);
}
}
操作对象
只为value设置了序列化器
package com.qzcsbj.demo;
import com.qzcsbj.demo.pojo.User;
import org.junit.jupiter.api.Test;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.context.SpringBootTest;

user.setUsername("jack");
user.setPassword("123456");
// 设置value序列化器
redisTemplate.setValueSerializer(new JdkSerializationRedisSerializer());
redisTemplate.opsForValue().set("user",user);
System.out.println("set对象完成。");
System.out.println("user: " + redisTemplate.opsForValue().get("user"));
}
}
为key和value设置序列化器
package com.qzcsbj.demo;

redisTemplate.opsForValue().set("user",user);
System.out.println("set对象完成。");
System.out.println("user: " + redisTemplate.opsForValue().get("user"));

@SpringBootTest
public class MyTest {
@Autowired
private StringRedisTemplate stringRedisTemplate;
@Test
public void test2(){
stringRedisTemplate.opsForValue().set("name","jack");
System.out.println("set字符串完成。");
Object name = stringRedisTemplate.opsForValue().get("name");
System.out.println("获取到的name: " + name);
}
}

使用总结
如果用redisTemplate，一般是创建配置类自定义RedisTemplate来设置序列化器
package com.qzcsbj.demo.config;
import org.springframework.beans.factory.annotation.Autowired;
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.core.StringRedisTemplate;
import org.springframework.data.redis.serializer.GenericJackson2JsonRedisSerializer;
import org.springframework.data.redis.serializer.StringRedisSerializer;
/**
* @公众号 : 全栈测试笔记
* @博客 : www.cnblogs.com/uncleyong
* @微信 : ren168632201
* @描述 : <>
*/
@Configuration
public class RedisConfig {
@Autowired
private RedisConnectionFactory connectionFactory;
@Bean
public RedisTemplate redisTemplate(){
RedisTemplate redisTemplate=new RedisTemplate<>();
redisTemplate.setConnectionFactory(connectionFactory);
// 指定key、value的序列化策略
redisTemplate.setKeySerializer(new StringRedisSerializer());
redisTemplate.setValueSerializer(new GenericJackson2JsonRedisSerializer());
redisTemplate.setHashKeySerializer(new StringRedisSerializer());
redisTemplate.afterPropertiesSet();
return redisTemplate;
}
@Bean
public StringRedisTemplate stringRedisTemplate(){
StringRedisTemplate stringRedisTemplate=new StringRedisTemplate();
stringRedisTemplate.setConnectionFactory(connectionFactory);
return stringRedisTemplate;
}
}
