hibernate 注解1：M

A----->B(1:M)

class  A{

@OneToMany(mappedBy="alarmPlan",cascade=CascadeType.ALL)

private  List<B> blist;

}

class B{

@ManyToOne(targetEntity=com.test.A.class,fetch= FetchType.Lazy,cascade=CascadeType.ALL)

@JoinColumn(name="B表关联A表的列名B_ID"，referColum)

Private A  a；

}

hibernate  could not execute native bulk manipulation query

主见产生重复时候
