Spring Boot 2.1.0和Java 11上的Spring Data Redis无法工作

Question

我把我的应用更新到了Spring Boot 2.1.0和Java 11，从那以后我的Redis就不能工作了。

当我调用findById()时，结果为空，那么就没有问题了。当我调用findById()时，如果有一个结果，那么应用程序/线程就会卡在这一点上，什么也不会发生。

当我使用Spring Boot 2.0.6和Java9时，相同的代码工作得很好。

我尝试使用LettuceConnectionFactory和JedisConnectionFactory，得到了相同的结果。

我的Redis配置：

@Configuration
@EnableRedisRepositories
public class RedisConfiguration {

    @Bean
    RedisConnectionFactory connectionFactory() {
        return new LettuceConnectionFactory();
    }

    @Bean
    @Primary
    RedisTemplate<String, Object> redisTemplate(RedisConnectionFactory connectionFactory) {
        RedisTemplate<String, Object> template = new RedisTemplate<>();
        template.setConnectionFactory(connectionFactory);
        template.setKeySerializer(new StringRedisSerializer());
        template.setValueSerializer(new GenericJackson2JsonRedisSerializer());

        return template;
    }
}

我的实体：

@Value
@RedisHash("token")
public class Token {

    @Id 
    private String key;

    private String value;

    @TimeToLive
    private Long expiration;

}

我的存储库只是扩展了CrudRepository，我只使用了提供的方法。

Redis-服务器版本是在OSX (开发)/ Ubuntu (测试)上运行的Redis server v=4.0.9。

我是否错过了使用Java 11 / Boot 2.1必须应用的一些更改？

Answer 1

将变量key的名称更改为id。

有一个bug使得带有@Id注释的字段必须被命名为id。

public class Token implements Serializable {
    @Id private String id;
    private String code;
    @TimeToLive private Long expiration;
}

Answer 2

我找到了一个解决方案。我创建了一个测试项目，发现CrudRepository#findById()方法抛出了以下异常。

我将实体上的@Value注释更改为@Data @AllArgsConstructor，现在它工作得很好。

似乎在spring-data-redis中有一些变化。

Answer 3

我只是遇到了同样的错误，并通过在我的kotlin模型中将val设置为var来找到解决方案。我没有使用@value、@Data或@AllArgsConstructor。

@RedisHash("keys")
class Token (
        @Id
        val key: String? = null,
        @TimeToLive
        var expiration: Long
)

我的日志是这样的：

org.springframework.data.keyvalue.core.UncategorizedKeyValueException: No accessor to set property @org.springframework.data.redis.core.TimeToLive(unit=SECONDS)private final long oauth2demo.oauth2clientdemo.Token.expiration!; nested exception is java.lang.UnsupportedOperationException: No accessor to set property @org.springframework.data.redis.core.TimeToLive(unit=SECONDS)private final long oauth2demo.oauth2clientdemo.Token.expiration!
