本文介绍了Spring CrudRepository 在自定义查询方法定义上抛出 AbstractMethodError的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
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.
据我了解，问题在于 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实现.
I'm trying to create a custom query in an interface which extends the CrudRepository interface. Unfortunately for some reason every time I receive a java.lang.AbstractMethodError. Please see the full stack trace below.
As far as I understand, the problem is that Spring framework should "magically" create an implementation to my method declaration, but for some reason it doesn't make it.
存储库接口:
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
}
呈现实体类:
@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;
}
}

推荐答案
这个问题可能是由于您的 Spring Data Commons jar 和 Spring Data JPA jar 不兼容而引起的.请使用 mvn dependency:tree 命令检查这一点.
This issue might be arising due to an incompatibility of your Spring Data Commons jar and Spring Data JPA jars. Please check this using mvn dependency:tree command.
