BeanUtils.copyProperties 方法，克隆类

Posted 2022-06-25 诺浅

定义一个BeanUtils工具类

public class BeanUtils
	public static <T, R> R clone(T o, Class<R> targetClass) 
	    R r;
	    try 
	        r = targetClass.newInstance();
	     catch (InstantiationException | IllegalAccessException e) 
	        throw new RuntimeException("clone error");
	    
	    org.springframework.beans.BeanUtils.copyProperties(o, r);
	    return r;
	

使用

GetAdvanceSaleDtoResp resp = BeanUtils.clone(advanceSale, GetAdvanceSaleDtoResp.class);
