参数配置

@ConfigurationProperties(prefix = "spring.redis")
public class EasyliaoRedisProperties {

    private Boolean enable = true;

    public Boolean getEnable() {
        return enable;
    }

    public void setEnable(Boolean enable) {
        this.enable = enable;
    }
}

Redis配置

@Configuration
@EnableConfigurationProperties(EasyliaoRedisProperties.class)
@ConditionalOnProperty(value = "spring.redis.enable", havingValue = "true")
public class RedisConfiguration {

    @Bean("redisTemplate")
    public RedisTemplate<String, Object> redisTemplate(LettuceConnectionFactory lettuceConnectionFactory) {

        // 设置序列化
        Jackson2JsonRedisSerializer<Object> jackson2JsonRedisSerializer = new Jackson2JsonRedisSerializer<Object>(Object.class);
        ObjectMapper objectMapper = new ObjectMapper();
        objectMapper.setVisibility(PropertyAccessor.ALL, JsonAutoDetect.Visibility.ANY);
        objectMapper.activateDefaultTyping(LaissezFaireSubTypeValidator.instance, ObjectMapper.DefaultTyping.NON_FINAL);
        jackson2JsonRedisSerializer.setObjectMapper(objectMapper);

        // 配置redisTemplate
        RedisTemplate<String, Object> redisTemplate = new RedisTemplate<String, Object>();
        redisTemplate.setConnectionFactory(lettuceConnectionFactory);
        RedisSerializer<?> stringSerializer = new StringRedisSerializer();
        redisTemplate.setKeySerializer(stringSerializer);// key序列化
        redisTemplate.setValueSerializer(jackson2JsonRedisSerializer);// value序列化
        redisTemplate.setHashKeySerializer(stringSerializer);// Hash key序列化
        redisTemplate.setHashValueSerializer(jackson2JsonRedisSerializer);// Hash value序列化
        redisTemplate.afterPropertiesSet();
        return redisTemplate;

    }
}

配置spring.factories

在 resource/META-INF/spring.factories 中配置

org.springframework.boot.autoconfigure.EnableAutoConfiguration=\
  com.easyliao.framework.boot.redis.config.RedisConfiguration

使用

引入maven包后, 在 application.properties 中配置 spring.redis.enable=true 后可以自动注入bean, 直接调用

@Autowired
private RedisTemplate<String, Object> redisTemplate;

@Test
void contextLoads() {
    User user = new User();
    user.setName("admin");
    redisTemplate.opsForValue().set("name", user);
    Object name = redisTemplate.opsForValue().get("name");
    System.out.println(name.toString());
}
