为存储库定义自定义查询时出现 SpelQueryContext$SpelExtractor.size() 错误

问题描述 投票：0回答：1

我想要一种带有为存储库指定的查询的方法，而不是使用 hibernate 创建方法，但我收到了这些错误。

模特班

@Entity
@Data
@NoArgsConstructor
@AllArgsConstructor
public class Pokemons {
    @Id
    private UUID id;
    private String name;
    private String levels;
}

存储库

@Repository
public interface pokemonrepository extends CrudRepository<Pokemons, UUID> {
    List<Pokemons> findAllByName(String name);

    @Query("SELECT p.name FROM Pokemons p")
    List<String> getAllNames();
}

应用程序.属性

spring.sql.init.platform=h2
logging.level.org.hibernate.SQL=DEBUG
spring.jpa.show-sql=true

我得到的错误：-（与 SpelExtractor 有关吗？）

使用方法名称编写查询是可行的。定义一个自定义的则不然。

我尝试为口袋妖怪模型类编写一个命名查询，但后来我也遇到了上述拼写提取器错误。我不知道如何解决。

这是因为您的

spring-data-commons
版本与
spring-data-jpa
版本不匹配。

您正在使用 

spring-data-jpa-3.1.3
，预计来自 
SpelExtractor
的 
spring-data-commons
将具有添加到 
size()
中的 
spring-data-commons-3.1.3
方法。但现在你正在使用 
spring-data-commons-3.1.2
，所以它找不到这个方法并抛出 
NoSuchMethodError
。

由于您使用的是 Spring Boot 3.1.2 ，因此最好将 

spring-data-jpa
和 
spring-data-commons
对齐到相同的 3.1.2 版本。
