Spring boot注入多个redisTemplate，并更改默认序列化策略

1、添加maven依赖

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

2、配置文件中增加redis连接相关信息

spring.redis.hostName=192.168.0.134
spring.redis.port=6379
spring.redis.database=0
spring.redis.pool.max-idle=8
spring.redis.pool.min-idle=0
spring.redis.pool.max-active=8
spring.redis.pool.max-wait=-2

3、创建一个配置类

package com.example.config;

import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.boot.autoconfigure.EnableAutoConfiguration;
import org.springframework.boot.context.properties.ConfigurationProperties;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.data.redis.connection.jedis.JedisConnectionFactory;
import org.springframework.data.redis.core.RedisTemplate;
import org.springframework.data.redis.core.StringRedisTemplate;
import org.springframework.data.redis.serializer.Jackson2JsonRedisSerializer;

import com.fasterxml.jackson.annotation.JsonAutoDetect;
import com.fasterxml.jackson.annotation.PropertyAccessor;
import com.fasterxml.jackson.databind.ObjectMapper;

import redis.clients.jedis.JedisPoolConfig;

@Configuration
@EnableAutoConfiguration
public class RedisConfig {

    private static Logger logger = LoggerFactory.getLogger(RedisConfig.class);

    @Bean
    @ConfigurationProperties(prefix="spring.redis")
    public JedisPoolConfig getRedisConfig(){
        JedisPoolConfig config = new JedisPoolConfig();
        return config;
    }

    @Bean
    @ConfigurationProperties(prefix="spring.redis")
    public JedisConnectionFactory getConnectionFactory(){
        JedisConnectionFactory factory = new JedisConnectionFactory();
        JedisPoolConfig config = getRedisConfig();
        factory.setPoolConfig(config);
        logger.info("JedisConnectionFactory bean init success.");
        return factory;
    }

    @Bean
    public RedisTemplate getRedisTemplate(){
        RedisTemplate template = new StringRedisTemplate(getConnectionFactory()); //只能对字符串的键值操作
        System.out.println("生成template:" + template);
        return template;
    }
    
    @Bean(name = "LongRedisTemplate")
    public RedisTemplate getRedisTemplate1(){
        RedisTemplate template = new RedisTemplate(); //只能对字符串的键值操作
        template.setConnectionFactory(getConnectionFactory());
    
     // 使用Jackson2JsonRedisSerialize 替换默认序列化(默认采用的是JDK序列化)
        Jackson2JsonRedisSerializer
