JSP 中Spring的Resource类读写中文Properties实例代码


            JSP 中Spring的Resource类读写中文Properties

摘要: Spring对Properties的读取进行了完善而全面的封装，对于写则仍需配合FileOutputStream进行。







 package com.oolong.common.util;



import org.springframework.core.io.support.PathMatchingResourcePatternResolver;

import org.springframework.core.io.support.ResourcePatternResolver;

import java.io.*;

import java.util.*;



public class UserVar {

 private static String configFile = "classpath*:param.properties";

 private static org.springframework.core.io.Resource resourceWritable;

 private static Properties p;



 /**

  * 注意事项:

  * 1、properties放在source目录下

  * 2、param.properties至少有一对键值对

  */

 static {

  p = new Properties();

  org.springframework.core.io.Resource[] resources = null;

  try {

   ResourcePatternResolver resolver = new PathMatchingResourcePatternResolver();

   resources = resolver.getResources(configFile);

   if (resources != null) {

    for (org.springframework.core.io.Resource r : resources) {

     if (r != null) {

      p.load(r.getInputStream());

      resourceWritable = r;

     }

    }

   }

  } catch (IOException e1) {

   e1.printStackTrace();

  }

 }



 public static String get(String key) {

  String v = (String) p.get(key);

  if (v != null) {

   try {

    return new String(v.getBytes("ISO-8859-1"), "GBK");

   } catch (UnsupportedEncodingException e) {

    e.printStackTrace();

    return null;

   }

  }

  return null;

 }



 public static void set(String key,String value){

  if (null != resourceWritable) {

   try {

    OutputStream fos = new FileOutputStream(resourceWritable.getFile());

    Properties p = new Properties();

    p.load(resourceWritable.getInputStream());

    value = new String(value.getBytes("GBK"),"ISO-8859-1");

    p.setProperty(key, value);

    p.store(fos, null);

    fos.close();

   } catch (IOException e) {

    e.printStackTrace();

   }

  }

 }

}
