我正在尝试在我的代码库中实现Apache Configuration 2

import java.io.File;
import java.util.concurrent.TimeUnit;

import org.apache.commons.configuration2.PropertiesConfiguration;
import org.apache.commons.configuration2.builder.ConfigurationBuilderEvent;
import org.apache.commons.configuration2.builder.ReloadingFileBasedConfigurationBuilder;
import org.apache.commons.configuration2.builder.fluent.Parameters;
import org.apache.commons.configuration2.convert.DefaultListDelimiterHandler;
import org.apache.commons.configuration2.event.EventListener;
import org.apache.commons.configuration2.ex.ConfigurationException;
import org.apache.commons.configuration2.reloading.PeriodicReloadingTrigger;

import org.apache.commons.configuration2.CompositeConfiguration;

public class Test {

    private static final long DELAY_MILLIS = 10 * 60 * 5;


    public static void main(String[] args) {
        // TODO Auto-generated method stub
        CompositeConfiguration compositeConfiguration = new CompositeConfiguration();
        PropertiesConfiguration props = null;
        try {
            props = initPropertiesConfiguration(new File("/tmp/DEV.properties"));
        } catch (ConfigurationException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
        compositeConfiguration.addConfiguration( props …

我想利用 SequenceGenerator 并从序列生成器中获取下一个值。我想避免前往数据库并依靠序列生成器为我提供唯一值。此外，我使用该值在显示字段中显示唯一 ID，而不保留对象。
