PropertiesConfiguration是一个配置文件的加载工具类,封装了从配置文件里获取值并转化为基本数据类型的方法。
它来自commons-configuration-1.6.jar。
直接上代码:
public class Config {
private static PropertiesConfiguration config = null;
static {
try {
config = new PropertiesConfiguration(
"config.properties");
} catch (ConfigurationException e) {
e.printStackTrace();
}
}
public static String getString(String key) {
return config.getString(key);
}
public static String getString(String key, String def) {
return config.getString(key, def);
}
public static int getInt(String key) {
return config.getInt(key);
}
public static int getInt(String key, int def) {
return config.getInt(key, def);
}
public static long getLong(String key) {
return config.getLong(key);
}
public static long getLong(String key, long def) {
return config.getLong(key, def);
}
public static float getFloat(String key) {
return config.getFloat(key);
}
public static float getFloat(String key, float def) {
return config.getFloat(key, def);
}
public static double getDouble(String key) {
return config.getDouble(key);
}
public static double getDouble(String key, double def) {
return config.getDouble(key, def);
}
public static boolean getBoolean(String key) {
return config.getBoolean(key);
}
public static boolean getBoolean(String key, boolean def) {
return config.getBoolean(key, def);
}
public static String[] getStringArray(String key) {
return config.getStringArray(key);
}
@SuppressWarnings("unchecked")
public static List getList(String key) {
return config.getList(key);
}
@SuppressWarnings("unchecked")
public static List getList(String key, List def) {
return config.getList(key, def);
}
public static void setProperty(String key, Object value) {
config.setProperty(key, value);
}
}
