在项目中使用JedisPool连接redis出现NOAUTH Authentication required 的异常：

出现异常的代码：

@GetMapping("/redis")
    public String getMessage(){
        log.info(jedisPoolConfig.toString());
        log.info(jedisPool.toString());
        // 在try的括号种进行创建资源连接,会在try语句结束后自动释放，前提是这些可关闭的资源必须实现 java.lang.AutoCloseable 接口。
        try (Jedis jedis = jedisPool.getResource()){
            coffeeService.getAllCoffee().forEach(c ->{
                jedis.hset("springbucks-menu",c.getName(),Long.toString(c.getPrice().getAmountMinorLong()));
            });

            Map<String, String> menu = jedis.hgetAll("springbucks-menu");
            log.info("Menu:{}",menu);

            String price = jedis.hget("springbucks-menu", "espresso");
            log.info("espresso - {}", Money.ofMinor(CurrencyUnit.of("CNY"), Long.parseLong(price)));
        }

        return jedisPool.toString();
    }

原因：根据报错信息提示，是需要进行权限的验证。而联想到redis设置了密码，极有可能是没有Jedis连接池没有设置密码导致的。看了一下配置类，new JedisPool(jedisPoolConfig(),host) 这里根本没有设置密码：

@Slf4j
@Configuration
public class JedisConfiguration {

    @Bean
    @ConfigurationProperties(value = "diy.redis")
    public JedisPoolConfig jedisPoolConfig(){
        return new JedisPoolConfig();
    }

    @Bean(destroyMethod = "close")
    public JedisPool jedisPool(@Value("${diy.redis.host}") String host){
        return new JedisPool(jedisPoolConfig(),host);
    }

}

解决：

在application.properties 配置好参数，构造JedisPool 的时候传参即可。

@Slf4j
@Configuration
public class JedisConfiguration {

    @Value("${diy.redis.password}")
    private String password;
    
    @Bean
    @ConfigurationProperties(value = "diy.redis")
    public JedisPoolConfig jedisPoolConfig(){
        return new JedisPoolConfig();
    }

    @Bean(destroyMethod = "close")
    public JedisPool jedisPool(@Value("${diy.redis.host}") String host){
        return new JedisPool(jedisPoolConfig(),host,6379,2000,password);
    }
