判断传入的object是否为null, 为null返回defaultObject 不为null返回object

采用JDK8的Optional类解决对象判空时需要返回默认值的问题

getOrElse

public static <T> T getOrElse(T obj,

通过传入的condition验证obj是否满足条件 满足条件condition时，返回obj 不满足条件condition时，返回defaultObj

     public Foo(String obj){
          String value  = getOrElse(obj, "default", StringUtils::isNotBlank)
     }
