获取本地电脑用户目录下的配置文件信息

Step1：方法类

package com.hnmmli.g2common.utils;

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

public class PropertiesUtil
{
private static String userhome = "user.home";

private static String path = "configers";

public static Properties getProperties(String fileName)
{
StringBuilder dbConfiger = new StringBuilder(System.getProperty(userhome)).append(File.separator).append(path).append(File.separator).append(fileName);
Properties defaults = new Properties();
InputStream is = null;
try
{
is = new FileInputStream(dbConfiger.toString());
defaults.load(is);
}
catch (Exception e)
{
e.printStackTrace();
return null;
}
finally
{
if (is != null)
{
try
{
is.close();
}
catch (IOException e)
{
}
}
}
return defaults;
}
}

step2：应用
package com.hnmmli.g2intermodalweb.action.img;



import java.util.Properties;

import org.apache.commons.logging.Log;
import org.apache.commons.logging.LogFactory;

import com.hnmmli.g2common.utils.PropertiesUtil;

public class PropertyUtil {

//定义配置文件路径

//private static final String PROPERTY_FILE = "/g2storewebtest.properties";     


private static final Log logger = LogFactory.getLog(PropertyUtil.class); 


private static Properties config = null; 

    static 
    { 
       // InputStream in = PropertyUtil.class.getClassLoader().getResourceAsStream(PROPERTY_FILE);   
        try 
        { 
/*       fileconfig.properties InputStream in = new BufferedInputStream(new FileInputStream( 
                 "/g2storewebtest.properties"));   */
         config = PropertiesUtil.getProperties("fileconfig.properties");
         //System.out.println(">>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>fileconfig:"+JSONObject.toJSON(config));
       //InputStream in = PropertyUtil.class.getResourceAsStream("g2storewebtest.properties");  
         ///config = new Properties();  
          //  config.load(in); 
            //in.close(); 
        } 
        catch (Exception e) 
        { 
            logger.error(e); 
            System.out.println("");  
        } 
    } 
    
   
    /**
     * 更具key 获取value值
     * @param key
     * @return
     */
    public static String readValue(String key) 
    { 
        try 
        { 
            String value = config.getProperty(key); 
            return value; 
        } 
        catch (Exception e) 
        { 
            e.printStackTrace(); 
            logger.error("ConfigInfoError" + e.toString()); 
            return null; 
        } 
    }
   
}
