springboot + redis

本篇简述springboot集成redis，基于redis哨兵模式。

sproingboot 集成组件三步曲（参见springboot+JPA介绍：依赖、配置、封装）

（假定springboot脚手架已搭建完成并成功运行，可参考历史分享springboot+mybatis）

1. maven添加redis依赖

    org.springframework.boot
    spring-boot-starter-data-redis


     org.springframework.data
     spring-data-redis

2. redis 配置

2.1 yml

#spring
spring：

#redis
  redis:
    host: 192.168.2.9
    port: 6379
    password: CacheDB123
    jedis:
      pool:
        max-active: 8
        max-wait: 6000
        max-idle: 5
        min-idle: 1
    # 哨兵配置
    sentinel:
      master: mymaster
      nodes: 192.168.2.9:6379,192.168.2.10:6379

2.2 RedisTemplate config

import com.fasterxml.jackson.annotation.JsonAutoDetect;
import com.fasterxml.jackson.annotation.PropertyAccessor;
import com.fasterxml.jackson.databind.ObjectMapper;
import org.springframework.cache.annotation.CachingConfigurerSupport;
import org.springframework.cache.annotation.EnableCaching;
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 org.springframework.data.redis.serializer.RedisSerializer;
import org.springframework.data.redis.serializer.StringRedisSerializer;

@EnableCaching
@Configuration
public class RedisConfig extends CachingConfigurerSupport {

    /**
     * redis模板
     * @param connectionFactory
     * @return
     */
    @Bean
    public RedisTemplate redisTemplate(RedisConnectionFactory connectionFactory) {
        RedisTemplate redisTemplate = new RedisTemplate<>();
        redisTemplate.setConnectionFactory(connectionFactory);

        // 使用Jackson2JsonRedisSerializer来序列化和反序列化redis的value值（默认使用JDK的序列化方式）
        Jackson2JsonRedisSerializer
