解决方法：

原代码：

@OneToMany(cascade={CascadeType.REMOVE},fetch=FetchType.EAGER,mappedBy="user_table")

 @OrderBy("account ASC")

 private Set<KpsysLog> kpsyslog;

 

@ManyToOne

 @JoinColumn(name="account")

 private user_table usert;

改为：

@OneToMany(cascade={CascadeType.REMOVE},fetch=FetchType.EAGER,mappedBy="usert")

@OrderBy("account ASC")

private Set<KpsysLog> kpsyslog;

@ManyToOne

@JoinColumn(name="account")

private user_table usert;
