注意依賴，springframework下的復制順序為 (目標對象,新對象) import org.springframework.beans.BeanUtils;public static void main(String[] args) {InterfaceCaseDO oldInterfaceCase = new InterfaceCaseDO();oldInterfaceCase.setCaseName("zhangsan");oldInterfaceCase.setId(1l);oldInterfaceCase.setSendBody("lis");oldInterfaceCase.setProtocol("wangsu");oldInterfaceCase.setUpdateUser("zhaoliu");InterfaceCaseDO newInterfaceCase = new InterfaceCaseDO();BeanUtils.copyProperties(oldInterfaceCase,newInterfaceCase);newInterfaceCase.setImId(1);System.out.println(newInterfaceCase.toString());} 特別注意，一定要注意看清楚自己的依賴， 如果是org.apache.commons.beanutils.BeanUtils 那么復制順序為(新對象，目標對象) import org.apache.commons.beanutils.BeanUtils;public static void main(String[] args) throws InvocationTargetException, IllegalAccessException {InterfaceCaseDO oldInterfaceCase = new InterfaceCaseDO();oldInterfaceCase.setCaseName("zhangsan");oldInterfaceCase.setId(1l);oldInterfaceCase.setSendBody("lis");oldInterfaceCase.setProtocol("wangsu");oldInterfaceCase.setUpdateUser("zhaoliu");InterfaceCaseDO newInterfaceCase = new InterfaceCaseDO();BeanUtils.copyProperties(newInterfaceCase,oldInterfaceCase);newInterfaceCase.setImId(1);System.out.println(newInterfaceCase.toString());}}

另外，比如對象復制時，想排除某個屬性，可以使用springframework的復制方法，也就是第一種方法，在方法上加上額外的參數，如下

比如排除掉bean的id和name屬性，就可以這樣寫BeanUtils.copyProperties(oldInterfaceCase,newInterfaceCase,new String[]{"id","name"});也可以寫成BeanUtils.copyProperties(oldInterfaceCase,newInterfaceCase, "id","name");如果想指定新對象的屬性，比如id，在下面添加一個set就行了 BeanUtils.copyProperties(oldInterfaceCase,newInterfaceCase, "id","name"); newInterfaceCase.setImId(1); 這樣復制的新對象就可以指定值了
