Properties文件读取

不知道有没有人写过,感觉还不错

Properties文件读取主类:CProperties.java

import java.util.Properties;
import java.util.StringTokenizer;
import java.io.*;

public class CProperties{
    private Properties props = null;

    public CProperties(String filename){
        try{
            props = this.getProperties(filename);
        }
        catch(Exception ex){
        }
    }

    public String getResource(String key){
        String strRet = "";
        
        strRet = props.getProperty(key);
        return strRet;
    }
   
    private Properties getProperties(String filename) throws Exception{
        Properties props = new Properties();
        FileInputStream fs = null;

        try{
            //取出文件里所有的数据
            File f = new File(filename);
            fs = new FileInputStream(f);

            int filesize = fs.available();
            byte[] contentbytes = new byte[filesize];
   
            fs.read(contentbytes );
            String contentstr = new String(contentbytes );

            //按照行分解
            StringTokenizer stoken = new StringTokenizer(contentstr,"\n\r");

             while(stoken.hasMoreTokens()){
                    //取出每一行
                    String line = stoken.nextToken();
                    
                    int parsepos = line.indexof("=");
                    String key = line.substring(0,parsepos).trim();
                    String val = line.substring(parsepos+1).trim();

                    props.put(key,val);
            }
        }
        catch(Exception ex){
            throw ex;
        }
        finally{
            try{
                fs.close();
            }
            catch(Exception ex){
             }
        }

        return props;
    }
}
