Java Web项目中读取

如果是MAVEN项目，一般将配置文件放在WEB-INF所在的模块中，便于发布后的修改。

public class OSSFileUtil {

    public static final String OSSRESPATH = "utilsProps/OSSRes.properties";
    public static String accessKeyId ;
    public static String accessKeySecret ;
    public static String endpoint ;
    public static String CONTRACT_BUCKET ; //合同存储的bucket
    public static OSSClient client;

    public static final Properties prop = new Properties();

    static{
        try {
            String path = OSSFileUtil.class.getClassLoader().getResource("").toURI().getPath();
            log.info("OSSRes.properties path:"+path + OSSRESPATH);
            FileInputStream fis = new FileInputStream(new File(path + OSSRESPATH));
            prop.load(fis);
            accessKeyId = prop.getProperty("accessKeyId").trim();
            accessKeySecret = prop.getProperty("accessKeySecret").trim();
            endpoint = prop.getProperty("endpoint").trim();
            CONTRACT_BUCKET = prop.getProperty("CONTRACT_BUCKET").trim();
            client = new OSSClient(endpoint, accessKeyId, accessKeySecret);
        } catch (Exception e) {
            log.error("OSS文件工具类初始化失败!");
            e.printStackTrace();
        }
    }
