DBCP加載數據庫連接，參考老師的寫，還是獲取不到BasicDataSource對象啊。一直報空指針?

依賴文件

文件路徑??resources/dbcp.properties

dbcp.properties 配置里面

===================================================================

driverClassName=dm.jdbc.driver.DmDriver
url=jdbc:mysql://127.0.0.1:3306/imooc_db?userUnicode=true&characterEncoidng?=?UFT-8
username=root
password=
minIdle=5
mzxIdle=20
maxActive=400
initialSize=30
logAbandoned=true
removeAbandoned=true
maxWait=5000

==========================================================================

/**
*?數據源，static
*/
private?static?BasicDataSource?DS;
//配置文件位置?
private?static?final?String?cofigFile?=?"resources/dbcp.properties";

//?構造方法

public?void?DBCPUtils()?{
initDbcp();
}

//dbcp初始化代碼

private?void?initDbcp()?{
Properties?props?=?new?Properties();
try?{
//以流形式讀取配置文件???
File?file?=?new?File(cofigFile);
FileInputStream?in?=?new?FileInputStream(file);
props.load(in);
//得到數據源?
DS?=?BasicDataSourceFactory.createDataSource(props);
}?catch?(Exception?e)?{
//?TODO?Auto-generated?catch?block
e.printStackTrace();
}
}

-- 獲得數據庫連接

?//獲得數據庫連接? ?

public?Connection?getConn()?{
Connection?conn?=?null;
try?{
if(null?!=?DS)?{
conn?=?DS.getConnection();
//設置成手動提交事務
conn.setAutoCommit(false);
}
}?catch?(SQLException?e)?{
//?TODO?Auto-generated?catch?block
e.printStackTrace();
}
return?conn;
}

現在想要獲取BasicDataSource，可是一直就報錯NullPointExcepint ........
