Hibernate让Model支持关联扩展属性：

select new Jxc(a,b.mc) from Jxc as a,btb as b

在Model中创建构造方法:

Jxc(Jxc jxc ,String mc){

BeanUtilsBean.getInstance().copyProperties(this, jxc);

this.setMc(mc);

}

给Model设备transient属性：

@Transient

public String getMc() {

return mc;

}

public void setMc(String value) {

this.mc = value;

}
