Spring CrudRepository在自定义查询方法定义上抛出AbstractMethodError
我正在尝试在扩展CrudRepository接口的接口中创建自定义查询。 不幸的是，每次收到java.lang.AbstractMethodError时都会出于某些原因。 请参阅下面的完整堆栈跟踪。
据我所知，问题是Spring框架应该“神奇地”为我的方法声明创建一个实现，但由于某种原因它没有成功。
存储库界面：
public interface PresentationRepository extends CrudRepository { Iterable findAll(Sort sort); Page findAll(Pageable pageable); List findByTitle(String title); // the problematic line } 演示实体课程：
@Entity @Table(name = "presentation") public class Presentation { @Id @GeneratedValue(strategy = GenerationType.AUTO) @Column(name = "presentation_id") Integer id; String title; String logo; @Column(name = "length") Integer interval; @Column(name = "pages") Integer pageCount; Date created; Date modified; Date approved; Date published; Date deleted; @ManyToMany(fetch = FetchType.EAGER) @JoinTable( name = "presentation_filters", joinColumns = @JoinColumn(name = "presentation_id"), inverseJoinColumns = @JoinColumn(name = "filter_id") ) List filters; public Presentation() { } public Integer getId() { return id; } public void setId(Integer id) { this.id = id; } // OTHER GETTERS AND SETTERS FOR EVERY ATTRIBUTE public Map<FilterGroup, List> getGroupedFilters() { Map<FilterGroup, List> grouppedFilters = new HashMap(); for (Filter filter : filters ) { if(!grouppedFilters.containsKey(filter.getGroup())) { grouppedFilters.put(filter.getGroup(), new ArrayList()); } grouppedFilters.get(filter.getGroup()).add(filter); } return grouppedFilters; } }

由于Spring Data Commons jar和Spring Data JPA jar不兼容，可能会出现此问题。 请使用mvn dependency:tree命令检查这一点。
让您的接口扩展JpaRepository而不是CrudRepository 。
顺便说一句： JpaRepository扩展了CrudRepository
