springboot集成redis配置及使用

首页引入redis依赖

<parent>
  <groupId>org.springframework.boot</groupId>
  <artifactId>spring-boot-starter-parent</artifactId>
  <version>2.7.12</version>
  <relativePath/> <!-- lookup parent from repository -->
</parent>
<dependency>
   <groupId>org.springframework.boot</groupId>
   <artifactId>spring-boot-starter-data-redis</artifactId>

    <artifactId>jedis</artifactId>
</dependency>

配置文件

spring:
  redis:
    host: XXXXXX
    port: 6379
    password: XXXXXXX
    database: X
    pool:
      max-active: 100
      max-idle: 10
      max-wait: 100000

编写一个配置文件映射类

@Configuration
@ConfigurationProperties(prefix = "spring.redis")
@Data
public class RedisPO {
    private String host;
    private int port;
    private String password;
    private int database;

}

然后就是redis配置类

import com.fasterxml.jackson.annotation.JsonAutoDetect;
import com.fasterxml.jackson.annotation.PropertyAccessor;
import com.fasterxml.jackson.databind.ObjectMapper;
import com.luky.config.po.RedisPO;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.annotation.Qualifier;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.data.redis.connection.RedisConnectionFactory;
import org.springframework.data.redis.connection.RedisStandaloneConfiguration;
import org.springframework.data.redis.connection.jedis.JedisClientConfiguration;
import org.springframework.data.redis.connection.jedis.JedisConnectionFactory;
import org.springframework.data.redis.core.RedisTemplate;
import org.springframework.data.redis.serializer.Jackson2JsonRedisSerializer;
import org.springframework.data.redis.serializer.StringRedisSerializer;
import redis.clients.jedis.JedisPoolConfig;

import java.time.Duration;

@Configuration
public class RedisConfig {

    @Autowired
    private RedisPO redisPO;

    /**
     * redis链接工厂
     */
    @Bean
    public RedisConnectionFactory redisConnectionFactory() {
        RedisStandaloneConfiguration redis = new RedisStandaloneConfiguration(redisPO.getHost(), redisPO.getPort());
        redis.setDatabase(redisPO.getDatabase());
        redis.setPassword(redisPO.getPassword());
        JedisClientConfiguration.JedisPoolingClientConfigurationBuilder jedis = (JedisClientConfiguration.JedisPoolingClientConfigurationBuilder) JedisClientConfiguration.builder();
        jedis.poolConfig(getRedisConfig());
        JedisClientConfiguration jedisClientConfiguration = jedis.build();
        return new JedisConnectionFactory(redis, jedisClientConfiguration);
    }


    @Bean
    //Qualifier 要求bean有且只有一个
    public RedisTemplate<?, ?> redisTemplate(@Qualifier("redisConnectionFactory") RedisConnectionFactory redisConnectionFactory) {
        RedisTemplate<?, ?> redisTemplate = new RedisTemplate<>();
        Jackson2JsonRedisSerializer<Object> jackson2JsonRedisSerializer = getJackson2JsonRedisSerializer();
        redisTemplate.setConnectionFactory(redisConnectionFactory);
        redisTemplate.setKeySerializer(new StringRedisSerializer());
        redisTemplate.setValueSerializer(jackson2JsonRedisSerializer);
        redisTemplate.setHashKeySerializer(new StringRedisSerializer());
        redisTemplate.setHashValueSerializer(jackson2JsonRedisSerializer);
        redisTemplate.afterPropertiesSet();
        return redisTemplate;
    }

    private Jackson2JsonRedisSerializer<Object> getJackson2JsonRedisSerializer() {
        Jackson2JsonRedisSerializer<Object> jackson2JsonRedisSerializer = new Jackson2JsonRedisSerializer<>(Object.class);
        ObjectMapper om = new ObjectMapper();
        om.setVisibility(PropertyAccessor.ALL, JsonAutoDetect.Visibility.ANY);
        om.enableDefaultTyping(ObjectMapper.DefaultTyping.NON_FINAL);
        jackson2JsonRedisSerializer.setObjectMapper(om);
        return jackson2JsonRedisSerializer;
    }

    public JedisPoolConfig getRedisConfig() {
        JedisPoolConfig jedis = new JedisPoolConfig();
        jedis.setMaxTotal(50); //链接最大数 默认是8
        jedis.setMaxIdle(10); //允许最大空闲的链接数量 默认8
        jedis.setMaxWait(Duration.ofSeconds(1000));
        return jedis;
    }
}

之后就可以在任意地方引入不同类型的reids,例如

@Autowired
private RedisTemplate<String, Object> redisTemplate;
