获取properties文件中的配置

常用的两种获取properties文件中配置的方法

1. 通过getResourceAsStream()方法获取
   代码如下：

Properties prop = new Properties();
InputStream in = this.getClass().getResourceAsStream("application.properties" );
try {
prop.load(in);
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
userId = prop.getProperty("userId");
userToken = prop.getProperty("userToken");
```

2. 直接通过InputStream获取流

 Properties prop =  new  Properties(); 
  try {
   in1 = new BufferedInputStream(new FileInputStream("src/main/resources/application.properties"));
  } catch (FileNotFoundException e1) {
   e1.printStackTrace();
  }
try {
   prop.load(in);
  } catch (IOException e) {
   e.printStackTrace();
  }
   userId = prop.getProperty("userId");
   userToken = prop.getProperty("userToken");
