从对象中动态获取属性值

/*** 从对象中动态获取属性值* @param obj 对象* @param name 要获取的属性值* @return*/
 private static Object getObjectInfo(Object obj,String name){Object value = new Object();try {Field field = obj.getClass().getDeclaredField(name);field.setAccessible(true);value=field.get(obj);}catch (Exception e){e.getStackTrace();}return value;
 }

public static void main(String[] args){CatPo catPo = CatPo.builder().color("蓝色").build();String color = String.valueOf(getObjectInfo(catPo,"color"));System.out.println(color);
 }

结果：
