Java目录总结（四.properties文件的读取及读取位置 ）

一，这种方式是读取在jar包外面的配置文件的路径

public static void main(String[] args) {
  try{
  InputStream in=new BufferedInputStream(new FileInputStream("resource/properties/test.properties"));
  Properties p=new Properties();
  p.load(in);
  System.out.println("properties:"+p.getProperty("name")+","+p.getProperty("age"));
  if(in!=null)
  {
   in.close();
  }
  }catch (Exception e) {
   e.printStackTrace();// TODO: handle exception
  }
  
  
 }

二，读取在src根目录下文件的路径方式，这时配置文件Config.properties不能放在src下面的包内：

  private GetConfig(){

try{

Properties prop = new Properties();

//FileInputStream fileInputStream = new FileInputStream(new File(path()+"/Config.properties"));

//InputStream inputStream=this.getClass().getResourceAsStream("/com/haiqi/config/Config.properties");

   InputStream inputStream  = this.getClass().getClassLoader().getResourceAsStream("Config.properties"); 

prop.load(inputStream);

    this.driverName = prop.getProperty("driverName","");

    this.dbURL = prop.getProperty("dbURL","");

    this.userName = prop.getProperty("userName","");

    this.userPwd = prop.getProperty("userPwd","");

    this.times = prop.getProperty("times", "");

    this.url = prop.getProperty("url","");

}catch (Exception e) {

e.printStackTrace();

}

}

三，读取src下面包内的配置文件

private GetConfig(){

try{

Properties prop = new Properties();

//FileInputStream fileInputStream = new FileInputStream(new File(path()+"/Config.properties"));

InputStream inputStream=this.getClass().getResourceAsStream("/com/haiqi/config/Config.properties");

    //InputStream inputStream  = this.getClass().getClassLoader().getResourceAsStream("Config.properties"); 

prop.load(inputStream);

    this.driverName = prop.getProperty("driverName","");

    this.dbURL = prop.getProperty("dbURL","");

    this.userName = prop.getProperty("userName","");

    this.userPwd = prop.getProperty("userPwd","");

    this.times = prop.getProperty("times", "");

    this.url = prop.getProperty("url","");

}catch (Exception e) {

e.printStackTrace();

}

}
