运行具有更新属性值的批处理文件

Question

我完全迷失了如何做到这一点......所以一些帮助会很好。所以我用我的java程序创建了一个批处理文件（使用查询来收集一些数据并将其作为CSV文件输出）。我还有一个属性文件，以便我可以更改查询的参数。

我的批处理文件运行并执行我的代码，但问题是，当我更新我的属性文件中的查询参数以获得不同的结果时，我的批处理文件不会使用更新的值运行，而只运行旧的。

java -jar "googleanalyticsfile.jar"

这是我在我的蝙蝠文件中所拥有的，任何帮助都是很好的thx

所以这是我在java文件中的查询

private static GaData executeDataQuery(Analytics analytics, String metrics, String dimensions, String startDate, String endDate, String sort, String profileID) throws IOException {
    return analytics.data().ga().get("ga:" + profileID, // Table Id. ga: + profile id.
        startDate, // Start date.
        endDate, // End date.
        metrics) // Metrics.
        .setDimensions(dimensions)
        .setSort(sort)
        .setMaxResults(100)//this value needs to be an int not string
        .execute();

这是我初始化查询参数的地方 public static void main（String [] args）{

 try {
      ...some code
      //stuff imported from properties file
      CrunchifyGetPropertyValues metricValues = new CrunchifyGetPropertyValues();
      String metrics = metricValues.metrics();
      String dimensions = metricValues.dimensions();
      String startDate = metricValues.startDate();
      String endDate = metricValues.endDate();
      String sort = metricValues.sort();
      String profileID = metricValues.profileID();
      if (profileID == null) {
        System.err.println("No profiles found.");
      } else {
        GaData gaData = executeDataQuery(analytics, metrics, dimensions, startDate, endDate, sort, profileID);
        printGaData(gaData);
      }

    and i call the properties file by each string does that help at all?

是的......很多代码可能会被浓缩，但那就是我的CrunchifyGetPropertyValues

Answer 1

这是一支吸烟枪：

InputStream inputStream = getClass().getClassLoader().getResourceAsStream(propFileName);

您正在jar文件中加载属性文件。

磁盘上的文件永远不会被考虑。

您必须提供备用属性文件的完整路径，作为main方法的参数，或作为系统属性。

顺便说一句，您最好在inputStream致电之前检查null是否不是prop.load。
