读取 classes下的配置文件

调用：

Configure.getValue("discount.strategy.class");

　　

配置类：

package com.util;

import com.sun.javafx.fxml.PropertyNotFoundException;

import java.io.InputStream;
import java.util.Properties;

public class Configure {

    private static Properties config;

    static {
        System.out.println("初始化加载配置！");

        String filePath = "application.properties";

        config = new Properties();
        try {
            ClassLoader CL = Configure.class.getClassLoader();
            InputStream in;
            if (CL != null) {
                in = CL.getResourceAsStream(filePath);
            } else {
                in = ClassLoader.getSystemResourceAsStream(filePath);
            }
            config.load(in);
            in.close();
        } catch (Exception e) {
            throw new PropertyNotFoundException("服务器配置信息读取错误：" + e.getMessage());
        }
    }

    public static String getValue(String key) {
        if (config.containsKey(key)) {
            String value = config.getProperty(key);
            return value;
        } else {
            return "";
        }
    }

    public static int getValueInt(String key) {
        String value = getValue(key);
        int valueInt = 0;
        try {
            valueInt = Integer.parseInt(value);
        } catch (NumberFormatException e) {
            e.printStackTrace();
            return valueInt;
        }
        return valueInt;
    }
}
