最近我试图通过属性文件填充Google查询,我写了这些代码行:
public String getPropValues() throws IOException {
String result = "";
Properties prop = new Properties();
String propFileName = "config.properties";
InputStream inputStream = getClass().getClassLoader().getResourceAsStream(propFileName);
prop.load(inputStream);
if (inputStream == null) {
throw new FileNotFoundException("property file '" + propFileName + "' not found in the classpath");
}
Date time = new Date(System.currentTimeMillis());
// Get the property value and print it out
String user = prop.getProperty("user");
String company1 = prop.getProperty("startDate");
String company2 = prop.getProperty("endDate");
String company3 = prop.getProperty("company3");
result = "Company List = " + company1 + ", " + company2 + ", " + company3;
System.out.println(result + "\nProgram Ran on " + time + " by user=" + user);
return result;
}
从属性中获取数据
private static GaData executeDataQuery(Analytics analytics, String profileId) throws IOException {
return analytics.data().ga().get("ga:" + profileId, // Table Id. ga: + profile id.
"2014-05-19", // Start date.
"2014-05-20", // End date.
"ga:pageviews,ga:sessions,ga:uniquePageviews") // Metrics.
.setDimensions("ga:date")
.setSort("-ga:date")
.setMaxResults(25)
.execute();
}
这是我正在使用的查询,所以如何制作它以便我可以在属性文件中输入日期,以便将它链接到我的查询中的字段?
答案 0 :(得分:1)
您必须将日期作为字符串读取,然后将其转换为日期。
有两种方法可以实现(超过2种,但这两种是最常见的方式):
保存属性文件中的毫秒数,然后将该属性读取为Long并将其转换为Date:Date date = new Date(long_value);
保存格式化日期:2014/05/21,然后在您的文件中解析:How to parse a date?
例如:
String company1 = prop.getProperty("startDate");
// suppose that compan1 has the value 2014-05-21
DateFormat df = new SimpleDateFormat("yyyy-MM-dd");
Date result = df.parse(company1);
System.out.println(result);
