ClassPath根下config.properties文件內(nèi)容

uploads=F:/java/uploads

讀取properties類

package utils;

import java.io.*;
import java.util.Properties;

public class PropertiesGet {
    // 類名.class.getResourceAsStream(String path)
    //path 不以’/'開頭時默認是從此類所在的包下取資源
    // 以’/'開頭則是從ClassPath根下(即'/'代表src)獲取
    public static Properties getResult(String proFileName) throws IOException {
        Properties props = new Properties();
        InputStream inputStream = PropertiesGet.class.getResourceAsStream(proFileName);
        //*.properties配置文件，要使用UTF-8編碼，否則會現(xiàn)中文亂碼問題
        BufferedReader bf = new BufferedReader(new InputStreamReader(inputStream,"UTF-8"));
        props.load(bf);
        return  props;
    }
}

讀取實例

Properties props = PropertiesGet.getResult("/config.properties");
String filePath = props.getProperty("uploads");
out.println(filePath);
