原因为：之前写的properties工具类只支持Windows平台，以下是兼容 windows和linux两个平台的 properties工具类。
代码开始：
package com.cpcnet.util;
import java.io.*;
import java.util.Enumeration;
import java.util.HashMap;
import java.util.Map;
import java.util.Properties;
public class PropertiesUtil {
/**
* 得到某一个类的路径
*
* @param name
* @return
*/
public static String getPath(Class name) {
String strResult = null;
if (System.getProperty("os.name").toLowerCase().indexOf("window") > -1) {
strResult = name.getResource("/").toString().replace("file:/", "")
.replace("%20", " ");
} else {
strResult = name.getResource("/").toString().replace("file:", "")
.replace("%20", " ");
}
return strResult;
}
/**
* 读取所有的property
* @param filename properties文件路径
* @return 所有的property的集合(map形式)
*/
@SuppressWarnings("unchecked")
public static Map<String, String> getPropties(String filename) {
if (null == filename) {
return null;
}
String filePath = getPath(PropertiesUtil.class) + filename;
Properties props = new Properties();
InputStream in = null;
try {
in = new BufferedInputStream(new FileInputStream(filePath));
props.load(in);
Map<String, String> map = new HashMap<String, String>();
Enumeration en = props.propertyNames();
while (en.hasMoreElements()) {
String key = (String) en.nextElement();
String Property = props.getProperty(key);
map.put(key, Property);
}
return map;
// 关闭资源
} catch (FileNotFoundException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
} finally {
try {
in.close();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
return null;
}
/**
* 获取某个property的值
* @param filename 文件名
* @param key property的key
* @return property的value
*/
public static String getProp(String filename, String key) {
if (null == filename || null == key) {
return null;
}
String filePath = getPath(PropertiesUtil.class) + filename;
Properties props = new Properties();
InputStream in = null;
try {
in = new BufferedInputStream(new FileInputStream(filePath));
props.load(in);
return props.getProperty(key);
// 关闭资源
} catch (FileNotFoundException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
} finally {
try {
in.close();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
return null;
}
}
代码结束。
