这是两个类
这是一端
@Entity
public class Payroll implements Serializable{

private static final long serialVersionUID = 1L;
@Id

}
public void setSid(long sid) {

}
}
这是多端

}

}
public int getCount() {
return count;
}
public void setCount(int count) {
this.count = count;
}
public double getCost() {
return cost;
}
public void setCost(double cost) {
this.cost = cost;
}
public double getAmount() {
return amount;
}
public void setAmount(double amount) {

}
}
一开始将PayrollRow的list赋值给Payroll一端只保存一端失败
后来把PayrollRow里面的Payroll进行赋值 两者关联起来 结果还是只保存了Payroll的数据 请问何解 还有我如果想只通过一端保存来保存两个表的信息该怎么做 谢谢
按一楼修改后执行如下语句
payroll.setPid(30);
List<PayrollRow> pwl = payroll.getPayrollRow();
for (int i = 0;i<pwl.size();i++) {
pwl.get(i).setPayroll(payroll);
}
payroll.setPayrollRow(pwl);
payrollService.save(payroll)；
结果控制台输出的sql语句没有insert
只有这
Hibernate:
select
payrollrow_.prid,
payrollrow_.amount as amount2_5_,
payrollrow_.cost as cost3_5_,
payrollrow_.count as count4_5_,
payrollrow_.payroll_id as payroll_7_5_,
payrollrow_.process as process5_5_,
payrollrow_.style_number as style_nu6_5_
from
payrollrow payrollrow_
where
payrollrow_.prid=?
