我有一个需要在 Windows 和 Linux 上运行的 java swing 数据库应用程序。我的数据库连接详细信息存储在一个 XML 文件中，我会加载它们。
此应用程序可以在 Linux 上正确加载此属性，但不能在 Windows 上运行。
如何使用 Java 在多个平台上正确加载文件？
这是代码：
PropertyHandler propertyWriter = new PropertyHandler();
List keys = new ArrayList();
keys.add("ip");
keys.add("database");
Map localProps = propertyWriter.read(keys, "conf" + File.separatorChar + "properties.xml", true);//if false load from the local properties
//get properties from the xml in the internal package
List seKeys = new ArrayList();
seKeys.add("driver");
seKeys.add("username");
seKeys.add("password");
Map seProps = propertyWriter.read(seKeys, "conf" + File.separatorChar + "properties.xml", true);
String dsn = "jdbc:mysql://" + (String) localProps.get("ip") + ":3306/" + (String) localProps.get("database");
jDBCConnectionPool = new JDBCConnectionPool((String) seProps.get("driver"), dsn, (String) seProps.get("username"), (String) seProps.get("password"));
文件阅读器方法：
public Map read(List properties, String path, boolean isConfFromClassPath)
{
Properties prop = new Properties();
Map props = new HashMap();
try {
if (isConfFromClassPath) {
InputStream in = this.getClass().getClassLoader().getResourceAsStream(path);
prop.loadFromXML(in);
for (Iterator i = properties.iterator(); i.hasNext();) {
String key = (String) i.next();
props.put(key, prop.getProperty(key));
}
in.close();
} else {
FileInputStream in = new FileInputStream(path);
prop.loadFromXML(in);
for (Iterator i = properties.iterator(); i.hasNext();) {
String key = (String) i.next();
props.put(key, prop.getProperty(key));
}
in.close();
}
} catch (Exception ex) {
ex.printStackTrace();
}
return props;
}
