springboot 2.0.3整合redis

首先,需要安装redis , 可以去看我的另一篇文章 https://blog.csdn.net/weixin_40461281/article/details/81365150

windows安装网上教程有很多 , 再此就不介绍了

添加springboot数据操作jar包

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

填写基础配置yml格式

spring:
  redis:
    # 第0号库
    database: 0
    host: ip地址
    # 端口号
    port: 6379 
    password: 密码
    # 连接超时时间
    timeout: 5000

创建RedisConfig.java配置类

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.RedisCacheManager;
import org.springframework.data.redis.connection.RedisConnectionFactory;
import org.springframework.data.redis.core.RedisTemplate;
import org.springframework.data.redis.core.StringRedisTemplate;
import org.springframework.data.redis.serializer.Jackson2JsonRedisSerializer;
import org.springframework.data.redis.serializer.StringRedisSerializer;

@Configuration
@EnableCaching
public class RedisConfig extends CachingConfigurerSupport {
//    @Bean
//    public CacheManager cacheManager(RedisTemplate<?, ?> redisTemplate) {
//        CacheManager cacheManager = new RedisCacheManager(redisTemplate);
//        return cacheManager;
//        /*RedisCacheManager rcm = new RedisCacheManager(redisTemplate);
//        // 多个缓存的名称,目前只定义了一个
//        rcm.setCacheNames(Arrays.asList("thisredis"));
//        //设置缓存默认过期时间(秒)
//        rcm.setDefaultExpiration(600);
//        return rcm;*/
//    }

    // 以下两种redisTemplate自由根据场景选择
    @Bean
    public RedisTemplate<Object, Object> redisTemplate(RedisConnectionFactory connectionFactory) {
        RedisTemplate<Object, Object> template = new RedisTemplate<>();
        template.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 serializer = new Jackson2JsonRedisSerializer(Object.class);

        ObjectMapper mapper = new ObjectMapper();
        mapper.setVisibility(PropertyAccessor.ALL, JsonAutoDetect.Visibility.ANY);
        mapper.enableDefaultTyping(ObjectMapper.DefaultTyping.NON_FINAL);
        serializer.setObjectMapper(mapper);
        //设置默认序列化方案
        template.setDefaultSerializer(serializer);
        //使用StringRedisSerializer来序列化和反序列化redis的key值
        template.setKeySerializer(new StringRedisSerializer());

        //设置序列化Value的实例化对象
        template.afterPropertiesSet();
        return template;
    }
    @Bean
    public StringRedisTemplate stringRedisTemplate(RedisConnectionFactory factory) {
        StringRedisTemplate stringRedisTemplate = new StringRedisTemplate();
        stringRedisTemplate.setConnectionFactory(factory);
        return stringRedisTemplate;
    }

}

SpringRedisTemplate 用户操作字符串更为便捷 RedisTemplate 可操作多类型数据

RedisTemplate 用法请参考我的另一篇博客 https://mp.csdn.net/postedit/82011670

编写测试类

    @Autowired
    private StringRedisTemplate stringRedisTemplate;
    @Autowired
    private RedisTemplate redisTemplate;

    @Test
    public void testRedis() {
        // key value 设置key过期时间 单位秒
        stringRedisTemplate.opsForValue().set("111","222",60,TimeUnit.SECONDS);
        String s = stringRedisTemplate.opsForValue().get("111");
        System.out.println(s);
    }

连接成功
