1.读取xml

使用dom4j解析xml  下载地址：

import org.dom4j.Document;
import org.dom4j.Element;
import org.dom4j.io.SAXReader;

try {              File f = new File(filename);              if (!f.exists()) {                  System.out.println("  Error : Config file doesn't exist!");                  System.exit(1);              }              SAXReader reader = new SAXReader();              Document doc;              doc = reader.read(f);              Element root = doc.getRootElement();              Element data;              Iterator
      itr = root.elementIterator("VALUE");              data = (Element) itr.next();                config.server = data.elementText("server").trim();              config.user = data.elementText("user").trim();              config.pass = data.elementText("pass").trim();              config.port = data.elementText("port").trim();              config.dbname = data.elementText("dbname").trim();            } catch (Exception ex) {              System.out.println("Error : " + ex.toString());          }

 

测试xml

       
           
                
                 
       
        127.0.0.1
                 
       
        users
                 
       
        root
                 
       
        pass
                 
       
        3306
             
        
     

2.读取properties

Properties prop = new Properties();//        ClassLoader classLoader = this.getClass().getClassLoader();//        InputStream is = classLoader.getResourceAsStream("/healthfile.properties");        //spring中         ServletContext context = this.getServletContext();        InputStream is = context.getResourceAsStream("/WEB-INF/classes/healthfile.properties");         //javase         //InputStream is = this.getClass().getResourceAsStream("/resource/sqlAddress.properties");        prop.load(is);        is.close();        String implClass = prop.getProperty("impl.class");        String statichtmlLocalRootPath = prop.getProperty("statichtml.local.rootPath");
