BeanUtils.copyProperties和beanCopier.copy的性能差距
public static void main(String[] args) { MobileCardCompanyDO cardPayOrderModel = new MobileCardCompanyDO(); cardPayOrderModel.setCompanyCode("HS"); cardPayOrderModel.setCompanyDesc("a1231241241awdasdf"); cardPayOrderModel.setCompanyName("123124dzvsds"); cardPayOrderModel.setId(2l); cardPayOrderModel.setStatus("1"); CompanyModel companyModel = new CompanyModel(); /** * 10W次 * BeanUtils.copyProperties：718 * beanCopier.copy：56 */ /** * 100W次 * BeanUtils.copyProperties：5673 * beanCopier.copy：70 */ //BeanUtils性能 long start = System.currentTimeMillis(); for (int i = 0; i < 1000000; i++) { BeanUtils.copyProperties(cardPayOrderModel, companyModel); } long end = System.currentTimeMillis(); System.out.println(end - start); //BeanCopier性能 long start1 = System.currentTimeMillis(); BeanCopier beanCopier = BeanCopier.create(MobileCardCompanyDO.class, CompanyModel.class, false); for (int i = 0; i < 1000000; i++) { beanCopier.copy(cardPayOrderModel, companyModel, null); } long end1 = System.currentTimeMillis(); System.out.println(end1 - start1); }如果系统中有很多属性拷贝，对系统的性能还是有影响的。建议使用cglib。
