什么问题呢?

@Configuration
//@ConfigurationProperties(prefix = "spring.redis")
@AutoConfigureBefore(RedisTemplate.class)
public class config {
    private String password;
    @Autowired
    private RedisProperties.Sentinel sentinel;

前面这样改应该就可以了。
你的34行报了空指针因为你没把Sentinel 注入进来,取不到值。这样注入不行的话就直接注入RedisProperties

@Configuration
//@ConfigurationProperties(prefix = "spring.redis")
@AutoConfigureBefore(RedisTemplate.class)
public class config {
    private String password;
    @Autowired
    private RedisProperties redisProperties;

这样写。
