问题 I'm using the code below to check if an hour is between two other specific hours: String openHour = "08:00 AM"; String currentHour = "10:00 PM"; String closeHour = "11:00 PM"; //Change to 02:00 AM doesn't work!!! SimpleDateFormat format = new SimpleDateFormat("hh:mm a"); Date openHourDate = format.parse(openHour); Date currentHourDate = format.parse(currentHour); Date closeHourDate = format.parse(closeHour); Calendar openCalendar = Calendar.getInstance(); openCalendar.setTime(openHourDate);

How do I update RestTemplate to correctly map Java Dates?

由 ◇◆丶佛笑我妖孽 提交于 2019-12-02 07:43:55
问题 I have an issue where my RestTemplate.postForEntity(url, restRequest, RepoResponse.class) call is failing because it can't deserialise dates of the form: 2019-02-01T12:00:00.000-0500 because of the missing colon in the timezone. Based on this answer, it looks like I want to change the date formatting of my RestTemplate 's ObjectMapper . I've tried a solution here: https://stackoverflow.com/a/38286322/14250 Which gives me the following code: restTemplate = new RestTemplate(); ObjectMapper

Java Time: Get max number of weeks for particular year

由 五迷三道 提交于 2019-12-02 01:25:04
问题 I only found a solution for Joda Time. My solution works only if the last day is not in the first week: LocalDate.now() // or any other LocalDate .withDayOfMonth(31) .withMonth(12) .get(weekFields.weekOfWeekBasedYear()) So what is the correct way in Java Time (like in Joda Time)? 回答1: This information is available directly using the java.time.* API. The key method is rangeRefinedBy(Temporal) on TemporalField . It allows you to obtain a ValueRange object that provides the minimum and maximum

Java 8 Date API - Get total number of weeks in a month

由 折月煮酒 提交于 2019-12-01 19:46:12
I have a Kotlin function to get the total number of weeks in a month Code fun getTotalWeeksInMonth(instant: Instant): Int { val calendar = Calendar.getInstance() calendar.time = Date.from(instant) return calendar.getActualMaximum(Calendar.WEEK_OF_MONTH) } However this is using a mix of the old Java date/time APIs ( Date and Calendar ) and the new APIs ( Instant ) How would I achieve the same result, using just the new APIs? Schidu Luca You can try something like this pair of lines: YearMonth currentYearMonth = YearMonth.now( ZoneId.systemDefault() ) ; int weeks = currentYearMonth .atEndOfMonth

JPA Storing OffsetDateTime with ZoneOffset

由 ＊爱你＆永不变心＊ 提交于 2019-11-29 06:16:29
问题 I have the following entity class: @Entity public class Event { private OffsetDateTime startDateTime; // ... } However, persisting and then reading the entity to/from the database with JPA 2.2 results in a loss of information : the ZoneOffset of startDateTime changes to UTC (the ZoneOffset used by the database timestamp). For instance: Event e = new Event(); e.setStartDateTime(OffsetDateTime.parse("2018-01-02T09:00-05:00")); e.getStartDateTime().getHour(); // 9 e.getStartDateTime().getOffset(
