spring-boot - 没有找到类型 With Cassandra Entity 的属性 findAll

问题描述

我的自定义存储库正在扩展 CassandraRepository

public interface CassandraRepository<T, ID> extends CrudRepository<T, ID> {
    <S extends T> List<S> saveAll(Iterable<S> var1);

    List<T> findAll();

    List<T> findAllById(Iterable<ID> var1);

    Slice<T> findAll(Pageable var1);

    <S extends T> S insert(S var1);

    <S extends T> List<S> insert(Iterable<S> var1);
}

我的自定义存储库类是

@Repository
public interface BookManageRepository extends CassandraRepository<BookEntity, BookKey> {
 ...
}

我正在关注异常

  Caused by: org.springframework.beans.factory.BeanCreationException: Error creating bean with 
    name 'bookManageRepository' defined in com.test.cassandra.repository.BookManageRepository 
    defined in @EnableReactiveCassandraRepositories declared on

获取异常“找不到类型的属性 findAll”，我的实体中没有任何属性findAll

使用 Springboot 2.3

这是我的图书实体

@Table("books")
public class BookEntity {
    
    @PrimaryKey
    private BookKey key;
    
    @Column("book_id")
    private String BookId;

    @Column("book_name")
    private String bookName;

    @Column("book_type")
    private String deviceType;

    @Column("created_date")
    private LocalDateTime createdDate;
    
    ...

}

配置

@Configuration
@EnableCassandraRepositories(basePackages = {"com.test.cassandra.repository"})
public class SpringDataCassandraConfig {

@Bean
public CqlSession session() {
    return CqlSession.builder().withKeyspace("mykeyspace").build();
}

解决方案

您必须将注释 @Repository 添加到您的存储库。如果您像这样编写 BookManageRepository，它应该会找到方法“findAll()”。

@Repository
public interface BookManageRepository extends CassandraRepository<BookEntity, BookKey> {
}
