Spring整合Redis最佳实践与性能优化指南 Redis作为高性能内存数据库，与Spring生态的深度整合是现代分布式系统的关键技术组合。通过连接池管理、序列化优化和高可用配置，开发者可以显著提升系统吞吐量和稳定性。在微服务架构中，合理的Redis配置能够有效解决缓存穿透、雪崩等典型问题，同时通过Lettuce或Jedis客户端的选择平衡性能与可靠性。本文以电商秒杀场景为例，详细解析连接池参数计算公式（max-active = QPS × avg_rt × 2），并对比Jackson2Json与JDK序列化的性能差异，为高并发场景提供经过验证的配置方案阅读详情

pom.xml文件：

注：若spring-data-redis版本过低，在spring中配置时有些类会没用

        <!-- redis begin -->
		<dependency>
			<groupId>redis.clients</groupId>
			<artifactId>jedis</artifactId>
			<version>2.9.0</version>
		</dependency>

        <!-- spring-redis实现 -->
		<dependency>
			<groupId>org.springframework.data</groupId>
			<artifactId>spring-data-redis</artifactId>
			<version>1.7.5.RELEASE</version>
		</dependency>

redis集群主要配置：

redis-cluster.properties

redis.host1=192.168.1.235
redis.port1=7001
redis.host2=192.168.1.235
redis.port2=7002
redis.host3=192.168.1.235
redis.port3=7003
redis.host4=192.168.1.235
redis.port4=7004
redis.host5=192.168.1.235
redis.port5=7005
redis.host6=192.168.1.235
redis.port6=7006
 
#有多少个redis就设置多少
redis.maxRedirects=6
redis.maxIdle=30
redis.maxTotal=100
redis.minIdle=5
redis.maxWaitMillis=30000 
redis.testOnBorrow=true
redis.testOnReturn=true 
redis.testWhileIdle=true
redis.timeout=3000

redis 主从配置

redis-ms.properties

# Redis settings  
#sentinel1的IP和端口  
sentinel1.host=192.168.1.233
sentinel1.port=26379  
#sentinel2的IP和端口  
sentinel2.host=192.168.1.233
sentinel2.port=26378

#最大连接数，超过此连接时操作redis会报错  
im.hs.server.redis.maxTotal=5000  
im.hs.server.redis.maxWaitTime=1000  
im.hs.server.redis.testOnBorrow=true  
#最小闲置连接数，spring启动的时候自动建立该数目的连接供应用程序使用，不够的时候会申请。

使用：

@Service
@Transactional(readOnly=true)
public class UserServiceImpl implements UserService {
	
	@Autowired
	private UserDao userDao;
	@Autowired
	private RedisTemplate<String, Object> redisTemplate;
	
	@Override
	@Transactional(readOnly=false)
	public void add(final User user) {
		// TODO Auto-generated method stub
		userDao.save(user);
		System.out.println("--------------添加redis缓存---------------------------");
		
 
		redisTemplate.execute(new RedisCallback<Object>() {  
            @Override  
            public Object doInRedis(RedisConnection connection)  
                    throws DataAccessException {  
                connection.hSet(redisTemplate.getStringSerializer().serialize("SYS_USER_TAB"),
                        redisTemplate.getStringSerializer().serialize("USER_"+user.getId()),  
                        redisTemplate.getStringSerializer().serialize(JSONObject.toJSONString(user)));  
              System.out.println(redisTemplate.getStringSerializer().serialize("USER_"+user.getId()));
                return null;  
            }  
        });  
		
		
		
	}
 
}

异常处理：

1.Caused by: java.lang.NumberFormatException: For input string: "7006@17006"

解决办法:将redis的jar包改为2.9.0即可

2.(error) MOVED 11469 192.168.163.249:7002

解决办法:配置redis集群，单个redis无法存值
