在src  目录下建立configs.properties

backup.host = 192.168.1.6backup.user = rootbackup.pwd =pwd

 

建立静态类：

 

package com.ly.jxc.util;import java.io.IOException;import java.util.HashMap;import java.util.Map;import java.util.Properties;import org.springframework.beans.factory.config.PropertyPlaceholderConfigurer;import org.springframework.core.io.ClassPathResource;import org.springframework.core.io.Resource;import org.springframework.core.io.support.PropertiesLoaderUtils;/** * 配置文件读取类 * @author yq * 2014-09-29 */public class Configs extends PropertyPlaceholderConfigurer {  private static Map
     
       ctxPropertiesMap;  protected static void load(){      Resource resource = new ClassPathResource("/config.properties");    Properties props;    try {        props = PropertiesLoaderUtils.loadProperties(resource);    ctxPropertiesMap = new HashMap
      
       ();      for (Object key : props.keySet()) {          String keyStr = key.toString();          String value = props.getProperty(keyStr);          ctxPropertiesMap.put(keyStr, value);      }      } catch (IOException e) {        // TODO Auto-generated catch block        e.printStackTrace();    }}  /** * 返回int,带默认值 * @param name * @return */public static int getIntValue(String name,int defaultValue) {     if(ctxPropertiesMap ==null ||ctxPropertiesMap.isEmpty())        load();    if(ctxPropertiesMap.get(name)==null)    return defaultValue;    return Integer.parseInt((String)ctxPropertiesMap.get(name));  }  /** * 返回int * @param name * @return */public static int getIntValue(String name) {      if(ctxPropertiesMap ==null ||ctxPropertiesMap.isEmpty())        load();    if(ctxPropertiesMap.get(name)==null)    return 0;    return Integer.parseInt((String)ctxPropertiesMap.get(name));  }  /** * 返回string * @param name * @return */public static String getValue(String name) {      if(ctxPropertiesMap ==null || ctxPropertiesMap.isEmpty())        load();    return (String)ctxPropertiesMap.get(name);  }  }
      
     

然后配置静态类（详见我另一篇 http://www.cnblogs.com/yqweber/p/3992513.html） 就能在页面直接用来取值了.
