该工具类对于java项目中配置文件读取很方便~

 

示例代码：

package com.lky.util;import java.io.BufferedReader;import java.io.IOException;import java.io.InputStream;import java.io.InputStreamReader;import java.util.Properties;import org.apache.commons.logging.Log;import org.apache.commons.logging.LogFactory;/*** @ClassName: ReadConfigUtil* @Description: 读取配置文件工具类(properties类型和文件类型)* @author lky* @date 2015年10月26日* @version 1.0 */public class ReadConfigUtil {    private static Log log = LogFactory.getLog(ReadConfigUtil.class);    private InputStream inputStream;    private BufferedReader bReader;    private Properties config;    private String strline;    public String getStrline() {        return strline;    }    public void setStrline(String strline) {        this.strline = strline;    }    /**     * @describe 构造函数     * @param fileName 文件名     * @param flag   若为true，则表示读取properties类型的文件，否则为txt文件     */    public ReadConfigUtil(String fileName, boolean flag) {        config = null;        bReader = null;        inputStream = ReadConfigUtil.class.getClassLoader().getResourceAsStream(fileName);        try {            if (flag) {                config = new Properties();                config.load(inputStream);            } else {                bReader = new BufferedReader(new InputStreamReader(inputStream, "utf-8"));                setStrline(readFile());            }        } catch (IOException e) {            e.printStackTrace();        } finally {            try {                if (bReader != null) {                    bReader.close();                }                if (inputStream != null) {                    inputStream.close();                }            } catch (IOException e) {                e.printStackTrace();            }        }    }    public String getValue(String key) {        return config.getProperty(key);    }    private  String readFile() {        StringBuffer sBuffer = new StringBuffer();        try {            String line = null;            while ((line = bReader.readLine()) != null) {                if (line.trim().length() > 0 && (!line.trim().startsWith("#"))) {                    sBuffer.append(line);                    sBuffer.append("\n");                }            }        } catch (Exception e) {            log.info("读文件异常！！！！");        }        return sBuffer.toString();    }    public static void main(String args[]) {        System.out.println(new ReadConfigUtil("sava.txt", false).getStrline());        System.out.println(new ReadConfigUtil("test.properties", true).getValue("ip"));        System.out.println(new ReadConfigUtil("test.properties", true).getValue("uame"));        System.out.println(new ReadConfigUtil("test.properties", true).getValue("password"));    }}
