JPA休眠到很多NestedServletException问题

添加具有ID的职位的查询，将其添加到Employee实体中设置的职位并保存Employee实体时，出现此错误

    .....

员工实体

@ManyToMany(cascade = {CascadeType.PERSIST, CascadeType.MERGE, CascadeType.DETACH, CascadeType.REFRESH}, fetch = FetchType.LAZY)
@Fetch(value= FetchMode.SELECT)
@JoinTable(name = "employees_jobs",
        joinColumns = @JoinColumn(name = "employee_id"),
        inverseJoinColumns = @JoinColumn(name = "job_id"))

工作实体

@ManyToMany(mappedBy = "jobs")
private Set<Employee> employees = new HashSet<>();

提前感谢！

已解决！是由龙目岛引起的。我删除了@Data注释并添加了

@ToString(exclude = "listName")

在实体类的顶部。 Lombok生成的ToString方法是stackoverflow错误的原因]
