自定义前缀的redis

1. 读取配置文件redis.properties

 redis.host=192.168.0.1
 redis.port=6379

2. 程序启动读取配置文件 SpringBoot启动类添加注解@PropertySource

@SpringBootApplication
@PropertySource(value = {"classpath:config/redis.properties"})
public class RedisApplication {
 
    public static void main(String[] args) throws IOException {
        SpringApplication.run(RedisApplication.class, args);
    }
}

3.引入redis依赖

<dependency>
     <groupId>org.springframework.boot</groupId>
     <artifactId>spring-boot-starter-data-redis</artifactId>
</dependency>
<dependency>
     <groupId>redis.clients</groupId>
     <artifactId>jedis</artifactId>
     <version>2.9.0</version>
</dependency>

4.添加redis配置类

@Configuration
@ConditionalOnClass(RedisOperations.class)
@EnableConfigurationProperties(RedisProperties.class)
@Component
public class RedisAutoConfiguration {
 
    @Value("${redis.host}")
    private String host;
    @Value("${redis.port}")
    private int port;
 
    @Bean
    public RedisConnectionFactory connectionFactory() {
        JedisPoolConfig poolConfig = new JedisPoolConfig();
        JedisClientConfiguration clientConfig = JedisClientConfiguration.builder()
                .usePooling().poolConfig(poolConfig).and().build();
        RedisStandaloneConfiguration redisConfig = new RedisStandaloneConfiguration();
        redisConfig.setHostName(host);
        redisConfig.setPort(port);
 
        return new JedisConnectionFactory(redisConfig,clientConfig);
    }
 
    @Bean
    @ConditionalOnMissingBean(name = "redisTemplate")
    public RedisTemplate<Object, Object> redisTemplate() {
        RedisTemplate<Object, Object> template = new RedisTemplate<>();
        //使用fastjson序列化
        FastJsonRedisSerializer fastJsonRedisSerializer = new FastJsonRedisSerializer(Object.class);
        // value值的序列化采用fastJsonRedisSerializer
        template.setValueSerializer(fastJsonRedisSerializer);
        template.setHashValueSerializer(fastJsonRedisSerializer);
        // key的序列化采用StringRedisSerializer
        template.setKeySerializer(new StringRedisSerializer());
        template.setHashKeySerializer(new StringRedisSerializer());
 
        template.setConnectionFactory(connectionFactory());
        return template;
    }
 
    @Bean
    @ConditionalOnMissingBean(StringRedisTemplate.class)
    public StringRedisTemplate stringRedisTemplate() {
        StringRedisTemplate template = new StringRedisTemplate();
        template.setConnectionFactory(connectionFactory());
        return template;
    }
 
}
