1) 從 FormBean 復(fù)制值到 JavaBean 或者互相復(fù)制.
??????????? TdepartmentForm deptForm = (TdepartmentForm) form;
??????????? Tdepartment tdepartment = new Tdepartment();
??????????? BeanUtils.copyProperties(tdepartment, deptForm);
2) 復(fù)制實(shí)體(實(shí)體一般是動(dòng)態(tài)的代理類)為 ValueObject 防止原始實(shí)體的值被更新掉
??????????? Tproviderbill billVO = new Tproviderbill();
??????????? BeanUtils.copyProperties(billVO, dao.getBill(1));// 復(fù)制屬性, 防止原實(shí)體被修改
??????????? if(billVO.xxx == xxx) {
??????????????? billVO.setName(“aaaa”);
??????????? }
??????? // 保存查詢結(jié)果
??????? request.setAttribute("bill", billVO);

不過(guò), 又有人指出 CGLIB 復(fù)制 Bean 速度更快, 效率更高(目前尚未做相關(guān)測(cè)試)!

static BeanCopier copy = BeanCopier.create(Bean.class, Bean2.class, false);

void beanCopies(Object source , Object target)｛
??? copy.copy(source, target, null);
}

Apache BeanUtils 妙用
