Properties的getProperty（）方法獲取到亂碼

當Properties的key value對中含有中文時會產生亂碼 產生亂碼的代碼

Properties properties = new Properties();  
InputStream inputStream = this.getClass().getResourceAsStream("/application.properties");  
properties.load(inputStream );  
properties .getProperty("Full")//獲得的是亂碼
```

由於InputStream 不能讀取中文，因此採起reader把inputStream轉換成reader用字符流來讀取中文。

```
Properties properties = new Properties();  
InputStream inputStream = this.getClass().getResourceAsStream("/application.properties");  
BufferedReader bf = new BufferedReader(new    InputStreamReader(inputStream));  
properties.load(bf);  
properties .getProperty("Full")//亂碼問題解決了  
```
