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(); } } }}
