1. 使用ResourceBundle
ResourceBundle rb = ResourceBundle.getBundle("jdbcPath");
String filePath = rb.getString("filePath");
2. 使用自带的Properties 类
try {
InputStream in = new BufferedInputStream(new FileInputStream(
PROPERTY_FILE));
props.load(in);
in.close();
String value = props.getProperty(key);
return value;
} catch (Exception e) {
e.printStackTrace();
return null;
}
