java 的properties读取

package com.servlet;

import java.io.FileNotFoundException;
import java.io.InputStream;
import java.util.Properties;

public class TestPro {

/**
* @param args
* @throws FileNotFoundException
*/
public String getValue(String key)
{
String value = "" ;
// TestPro tt= new TestPro();
// String path = this.getClass().getResource("").getPath().toString();
// path = path.substring(0, path.indexOf("classes")-1) + "/src/test.properties";
// System.out.println(path);
Properties p = new Properties();
final InputStream in = this.getClass().getResourceAsStream("/test.properties");
// FileInputStream in = null;

try
{
p.load(in) ;
}catch(Exception e){
e.printStackTrace();
}

if(p.containsKey(key)){
value = p.getProperty(key);
}
return value;
}

public static void main(String[] args) {

TestPro tt =new TestPro();
System.out.println(tt.getValue("name"));
}

}
PS:final InputStream in = this.getClass().getResourceAsStream("/test.properties");
/代表工程目录。。、/是放在src下。。
不加。。是类的当前目录

第二种：
package com.doone.config;

import java.io.InputStream;
import java.util.Properties;
import org.apache.log4j.Logger;
import org.springframework.stereotype.Repository;

@Repository("getproperties")
public class GetWsProperties {

private static Logger logger = Logger.getLogger(GetWsProperties.class);

public Properties getWsValue()
{
final Properties properties = new Properties();
final InputStream in = this.getClass().getResourceAsStream("/webservice.properties");

try{
properties.load(in) ;
}catch(Exception e){
e.printStackTrace();
logger.info("读取webservice.properties文件失败...");
}
return properties ;
}

public static void main(String[] args)
{
GetWsProperties p = new GetWsProperties();
Properties pp = p.getWsValue();

System.out.println(pp.getProperty("SafeGuard_QS")+pp.size());
}
}
