我试图在扩展CrudRepository接口的接口中创建自定义查询。不幸的是，每次我收到java.lang.AbstractMethodError时出于某种原因。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＆＃34;为我的方法声明创建一个实现，但由于某种原因它没有实现它。
存储库界面：
public interface PresentationRepository extends CrudRepository<Presentation, Integer> {
Iterable<Presentation> findAll(Sort sort);
Page<Presentation> findAll(Pageable pageable);
List<Presentation> findByTitle(String title); // the problematic line
}
演示文稿：
@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<Filter> 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<Filter>> getGroupedFilters() {
Map<FilterGroup, List<Filter>> 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;
}
}

答案 0 :(得分：8)
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命令进行检查。
答案 1 :(得分：1)
让您的界面扩展JpaRepository而不是CrudRepository。
顺便说一句：JpaRepository延伸CrudRepository
