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();
}
}
}
}
