SpringBoot配置类：

@Configuration
public class RedissonConfig {

    @Resource
    private RedissonConfigProperites redissonConfigProperites;

    @Bean(destroyMethod="shutdown")
    RedissonClient redisson() {
        Config config = new Config();
        config.useSingleServer()
                .setAddress(redissonConfigProperites.getAddress())
                .setPassword(redissonConfigProperites.getPassword())
                .setDatabase(redissonConfigProperites.getDatabase());
        return Redisson.create(config);
    }

}

@Data
@Component
@ConfigurationProperties(prefix = "redisson")
public class RedissonConfigProperites {

    private String address;
    private String password;
    private int database;


}
