第二章 SpringBoot使用redis

1.在pom.xml 添加

 
            org.springframework.boot
            spring-boot-starter-data-redis
  
  
            com.fasterxml.jackson.module
            jackson-module-jaxb-annotations
  

2 .在application.yml 中配置reids

spring:
	redis:
	    database: 2
	    host: localhost
	    port: 6379
	    lettuce:
	      pool:
	        max-active: 8
	        max-idle: 8
	        max-wait: -1ms
	      shutdown-timeout: 100ms

3.编写redis.config.java

package org.example.redis.config;

import com.fasterxml.jackson.annotation.JsonAutoDetect;
import com.fasterxml.jackson.annotation.PropertyAccessor;
import com.fasterxml.jackson.databind.ObjectMapper;
import org.springframework.cache.CacheManager;
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.cache.RedisCacheConfiguration;
import org.springframework.data.redis.cache.RedisCacheManager;
import org.springframework.data.redis.connection.lettuce.LettuceConnectionFactory;
import org.springframework.data.redis.core.RedisTemplate;
import org.springframework.data.redis.serializer.*;

import java.time.Duration;

@Configuration
@EnableCaching
public class RedisConfig extends CachingConfigurerSupport {

/**
 * RedisTemplate配置
 * @param lettuceConnectionFactory
 * @return
 */
@Bean
public RedisTemplate redisTemplate(LettuceConnectionFactory lettuceConnectionFactory) {
    // 设置序列化
    Jackson2JsonRedisSerializer
