读取.properties配置文件

可以单独建一个工具类

package com.zh.util;

import java.io.File;
import java.io.FileInputStream;
import java.io.IOException;
import java.io.InputStream;
import java.util.Properties;

public class AppConfig {
	
	private static Properties configProperties = new Properties();

	static {
		InputStream is = null;
		try {
			File file = new File(System.getProperty("user.dir") + File.separator + "config.properties");
			if (file.exists()) {
				is = new FileInputStream(file);
				configProperties.load(is);
			} else {
				configProperties.load(AppConfig.class.getClassLoader().getResourceAsStream("config.properties"));
			}
		} catch (IOException e) {
			LoggerUtil.error("加载配置文件异常", e);
		} finally {
			if (is != null) {
				try {
					is.close();
				} catch (Exception e2) {
				}
				is = null;
			}
		}
	}

	public static String getConfigProperty(String key) {
		return (String) configProperties.get(key);
	}
}
