JPA Hibernate 多对多 NestedServletException 问题

Question

当我添加对具有 ID 的工作的查询、将它们添加到 Employee 实体中的工作集并保存 Employee 实体时出现此错误

        2020-02-29 18:01:53.689  WARN 18280 --- [nio-8083-exec-2] .m.m.a.ExceptionHandlerExceptionResolver : Resolved [org.springframework.web.util.NestedServletException: Handler dispatch failed; nested exception is java.lang.WhosebugError]

    .....

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<>();

提前致谢！

已解决！是龙目岛造成了这个问题。我删除了@Data 注释并添加了

@ToString(exclude = "listName")

在实体 class 之上。 Lombok生成的ToString方法是Whosebug错误的原因
