解决方法：

原代码：

@OneToMany(cascade={CascadeType.REMOVE},fetch=FetchType.EAGER,mappedBy="user_table")
 @OrderBy("account ASC")
 private Set 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;

@ManyToOne
@JoinColumn(name="account")
private user_table usert;
