一、引入依赖

在pom文件中引入依赖

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

二、配置redis

2.1 代码配置redis

在bs-boot-system中新增配置类，在基础目录下新增config包，放在config包下

package cn.com.wenyl.bs.config;

import com.fasterxml.jackson.annotation.JsonAutoDetect;
import com.fasterxml.jackson.annotation.PropertyAccessor;
import com.fasterxml.jackson.databind.ObjectMapper;
import com.fasterxml.jackson.databind.jsontype.impl.LaissezFaireSubTypeValidator;
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.StringRedisSerializer;

import java.nio.charset.StandardCharsets;

/**

 */
@Configuration
public class RedisConfig {

    @Bean
    public Jackson2JsonRedisSerializer<Object> jackson2JsonRedisSerializer(){
        Jackson2JsonRedisSerializer<Object> jackson2JsonRedisSerializer = new Jackson2JsonRedisSerializer<>(Object.class);
        ObjectMapper objectMapper = new ObjectMapper();
        objectMapper.setVisibility(PropertyAccessor.ALL, JsonAutoDetect.Visibility.ANY);
        objectMapper.activateDefaultTyping(LaissezFaireSubTypeValidator.instance, ObjectMapper.DefaultTyping.NON_FINAL);
        jackson2JsonRedisSerializer.setObjectMapper(objectMapper);
        return jackson2JsonRedisSerializer;
    }
    @Bean
    public RedisTemplate<Object, Object> redisTemplate(RedisConnectionFactory redisConnectionFactory) {
        RedisTemplate<Object, Object> redisTemplate = new RedisTemplate<>();
        redisTemplate.setConnectionFactory(redisConnectionFactory);
        redisTemplate.setKeySerializer(new StringRedisSerializer(StandardCharsets.UTF_8));
        redisTemplate.setHashKeySerializer(new StringRedisSerializer(StandardCharsets.UTF_8));
        redisTemplate.setValueSerializer(jackson2JsonRedisSerializer());
        redisTemplate.setHashValueSerializer(jackson2JsonRedisSerializer());
        return redisTemplate;
    }
}

2.2 yml配置redis链接信息

spring:
  redis:
    database: 3
    host: 8.142.145.60
    password: shijingredis@2022
    port: 56378
    jedis:
      pool:
        max-active: 8   #最大连接数据库连接数,设 -1 为没有限制
        max-idle: 8     #最大等待连接中的数量,设 0 为没有限制
        max-wait: -1ms  #最大建立连接等待时间。如果超过此时间将接到异常。设为-1表示无限制。
        min-idle: 0     #最小等待连接中的数量,设 0 为没有限制
      shutdown-timeout: 100ms

三、测试

在bs-boot-system工程建立测试类，测试正常即可

import cn.com.wenyl.bs.BSBootApplication;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.data.redis.core.RedisTemplate;
import org.springframework.test.context.junit4.SpringRunner;

import javax.annotation.Resource;

/**
 * @author Swimming Dragon
 * @description: 测试redis
 * @date 2023年12月04日 21:46
 */
@RunWith(SpringRunner.class)
@SpringBootTest(classes = BSBootApplication.class)
public class TestRedis {
    @Resource
    private RedisTemplate<Object,Object> redisTemplate;
    @Test
    public void testDatabase() throws Exception{
        redisTemplate.opsForValue().set("long","6666");
        System.out.println(redisTemplate.opsForValue().get("long"));
    }
}
