JAVA读取PROPERTIY文件/JAVA拷贝一个对象的方式

1.JAVA读取PROPERTIY文件

 

方法:

       public Properties reader(String fileName) {

              InputStream inputStream = this.getClass().getClassLoader()

                            .getResourceAsStream(fileName);

              Properties prop = new Properties();

              try {

                     prop.load(inputStream);

                     dLogger.debug("通用方法读取配置文件-----------OK");

              } catch (Exception e) {

                     dLogger.debug("通用方法读取配置文件报错了");

                     e.printStackTrace();

              }

 

              return prop;

       }

直接采用JAVA.UTIL.PROPERTIES的LOAD方法把流中的数据直接转化为key value的配对。就可以了。

fileName的文件需要放在Classes下面。

2.JAVA拷贝一个对象的方式

public class PackagePriceFlightVO implements Cloneable {

              public Object clone() throws CloneNotSupportedException {

              return super.clone();

       }

}
