Java 从配置文件读取属性值-蒲公英云

Java 从配置文件读取属性值

有时候，我们需要动态从文件中读取配置，在线上跑个脚本啥的，可以直接修改文件里面的属性值来改变代码的走向，现在用的是 java.util.Properties 来实现的，具体代码如下：

/** 配置，是仅仅浏览还是浏览并同步更新数据 */
    private static String ifSynOrJustViewWmsToGss;
    private static String everySheetWaitTime;
    private static String excelName;
static {
        Properties prop = new Properties();
        InputStream in = Object.class.getResourceAsStream("/stockConfig.properties");
        try {
            prop.load(in);
            ifSynOrJustViewWmsToGss = prop.getProperty("ifSynOrJustViewWmsToGss").trim();
            everySheetWaitTime = prop.getProperty("everySheetWaitTime").trim();
            excelName = prop.getProperty("excelName").trim();
            logger.info(String.format("库存同步配置文件读取完毕,ifSynOrJustViewWmsToGss:%s,everySheetWaitTime:%s,excelName:%s", ifSynOrJustViewWmsToGss, everySheetWaitTime, excelName));
        } catch (IOException e) {
            e.printStackTrace();
        }
    }

stockConfig.properties文件

# only if this value is "update",program will synchronize data truely
ifSynOrJustViewWmsToGss=view
# when read a excel one sheet,wait for a moment
everySheetWaitTime=3000
excelName=wms.xls
