我找不到为什么在Spring Boot应用程序中发生此错误的java.lang.IncompatibleClassChangeError：null

时间：2020-01-29 07:02:48

标签： java spring spring-boot repository

我使用Spring Boot，Hibernate，Postgres。我在使用spring boot项目时遇到麻烦。但是我无法弄清楚问题是什么以及何时会出现。无法注入我的存储库。有人知道我做错了吗？在这种情况下，可能不会注入存储库。 我正在使用spring-boot 2.2.2.RELEASE

更新： 现在我发现了另一件事。如果我删除此关系

    @OneToMany(mappedBy = "blocktest")
    private  List<BlocktestSubject> blocktestSubjects = new ArrayList<>();

    @OneToMany(mappedBy = "blocktest")
    private  List<BlocktestGroup> blocktestGroups = new ArrayList<>();

项目可以正确启动

这是我的其他实体：

@Getter
@Setter
@Table(name = Tables.BLOCKTEST_SUBJECT)
public class BlocktestSubject {
    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    private Long id;

    @Column(name = "subject_id", nullable = false, insertable = false, updatable = false)
    private Long subjectId;
    @ManyToOne(fetch = FetchType.LAZY)
    @JoinColumn(name = "subject_id")
    private Subject subject;

    @Column(name = "blocktest_id", nullable = false, insertable = false, updatable = false)
    private Long blocktestId;
    @ManyToOne(fetch = FetchType.LAZY)
    @JoinColumn(name = "blocktest_id")
    private Blocktest blocktest;

    @OneToMany(mappedBy = "blocktestSubject", fetch = FetchType.EAGER)
    private List<BSPCount> bspCounts;

    @OneToMany(mappedBy = "blocktestSubject")
    private final List<Rule> rules = new ArrayList<>();
}

@Entity
@Getter
@Setter
public class BlocktestGroup {
    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    private Long id;

    @Column(name = "blocktest_id", nullable = false, insertable = false, updatable = false)
    private Long blocktestId;
    @ManyToOne
    @JoinColumn(name = "blocktest_id")
    private Blocktest blocktest;

    @Column(name = "file_id", insertable = false, updatable = false, nullable = false)
    private Long fileId;
    @OneToOne
    @JoinColumn(name = "file_id")
    private TFile tFile;

}

答案 0 :(得分：0)

在将spring-boot项目从2.1.1.RELEASE升级到2.3.4.RELEASE时，我遇到了类似的问题。我找不到任何在线参考来提供帮助。 我尝试将Java版本从8升级到15，此问题已解决。尝试升级您的Java版本并共享，如果有帮助的话。
