redisspringboot

1. pom.xml新增依賴

        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter</artifactId>
    </dependency>

        <artifactId>spring-boot-starter-data-redis</artifactId>
    </dependency>
</dependencies>

2. application-dev.xml設定

#单机模式
spring:  
  redis:
    host: 192.168.56.101 # Redis服务器地址
    database: 0 # Redis数据库索引（默认为0）
    port: 6379 # Redis服务器连接端口
    password: redis # Redis服务器连接密码（默认为空）
    timeout: 300ms # 连接超时时间（毫秒）

# 哨兵模式

spring:
  redis:
    sentinel:
      master: mymaster
      nodes: 192.168.56.101:26379,192.168.56.102:26379,192.168.56.103:26379
      password: redis

3. java config設定（單一節點）

package com.powertrade.redis.common.config;

import com.fasterxml.jackson.annotation.JsonAutoDetect;

import org.springframework.data.redis.serializer.StringRedisSerializer;

import java.time.Duration;

/**

@EnableCaching
@Configuration

        redisTemplate.setConnectionFactory(redisConnectionFactory);
        redisTemplate.setKeySerializer(new StringRedisSerializer());
        redisTemplate.setValueSerializer(serializer);
        redisTemplate.setHashKeySerializer(new StringRedisSerializer());

        redisTemplate.afterPropertiesSet();
        return redisTemplate;
    }

        ObjectMapper objectMapper = new ObjectMapper();
        objectMapper.setVisibility(PropertyAccessor.ALL, JsonAutoDetect.Visibility.ANY);
        //必须设置，否则无法将JSON转化为对象，会转化成Map类型
        objectMapper.activateDefaultTyping(LaissezFaireSubTypeValidator.instance,ObjectMapper.DefaultTyping.NON_FINAL);
        serializer.setObjectMapper(objectMapper);
        return serializer;
    }

    @Bean

REDIS：超越SQL- NOSQL的觀點May 08, 2025 am 12:25 AM

Redis超越SQL數據庫的原因在於其高性能和靈活性。 1)Redis通過內存存儲實現極快的讀寫速度。 2)它支持多種數據結構，如列表和集合，適用於復雜數據處理。 3)單線程模型簡化開發，但高並發時可能成瓶頸。

REDIS：與傳統數據庫服務器的比較May 07, 2025 am 12:09 AM

Redis在高並發和低延遲場景下優於傳統數據庫，但不適合複雜查詢和事務處理。 1.Redis使用內存存儲，讀寫速度快，適合高並發和低延遲需求。 2.傳統數據庫基於磁盤，支持複雜查詢和事務處理，數據一致性和持久性強。 3.Redis適用於作為傳統數據庫的補充或替代，但需根據具體業務需求選擇。

Redis主要是數據庫嗎？May 05, 2025 am 12:07 AM

Redis主要是一個數據庫，但它不僅僅是數據庫。 1.作為數據庫，Redis支持持久化，適合高性能需求。 2.作為緩存，Redis提升應用響應速度。 3.作為消息代理，Redis支持發布-訂閱模式，適用於實時通信。

REDIS：鍵值數據存儲的指南May 02, 2025 am 12:10 AM

Redis是一個開源的內存數據結構存儲，用作數據庫、緩存和消息代理，適合需要快速響應和高並發的場景。 1.Redis使用內存存儲數據，提供微秒級的讀寫速度。 2.它支持多種數據結構，如字符串、列表、集合等。 3.Redis通過RDB和AOF機制實現數據持久化。 4.使用單線程模型和多路復用技術高效處理請求。 5.性能優化策略包括LRU算法和集群模式。
