Unparseable date: "2023-03-31T15:37"

As an AI language model, I do not have the capability to parse dates beyond its format. In this case, the date "2023-03-31T15:37" is missing the timezone information in its format. Without the timezone, it is impossible to determine the exact time and date. Please provide a valid date format including the timezone information for me to parse it.

java.text.ParseException: Unparseable date: "2023-03-31T15:38"

This error occurs because the date format "2023-03-31T15:38" cannot be parsed by the default date parser in Java. To parse this date, you need to create a SimpleDateFormat object with the correct date format pattern and use it to parse the date string.

Here's an example:

String dateString = "2023-03-31T15:38";
SimpleDateFormat dateFormat = new SimpleDateFormat("yyyy-MM-dd'T'HH:mm");
Date date = dateFormat.parse(dateString);

In the above code, we create a SimpleDateFormat object with the pattern "yyyy-MM-dd'T'HH:mm", which corresponds to the format of the date string. We then use this object to parse the date string and get a Date object.

Note that the format pattern includes the 'T' character, which is used to separate the date and time portions of the string. If your date string uses a different separator character (such as a space), you'll need to adjust the format pattern accordingly.

JSON parse error: Cannot deserialize value of type `java.util.Date` from String "2023-01-01": not a valid representation (error: Failed to parse Date value '2023-01-01': Unparseable date: "2023-01-01"); nested exception is com.fasterxml.jackson.databind.exc.InvalidFormatException: Cannot deserialize value of type `java.util.Date` from String "2023-01-01": not a valid representation (error: Failed to parse Date value '2023-01-01': Unparseable date: "2023-01-01")

这个错误是因为在将 JSON 字符串转换为 Java 对象时，日期格式不匹配导致的。可以通过在对应的属性上使用 `@JsonFormat` 注解指定日期格式来解决这个问题。

例如，如果你的日期格式为 "yyyy-MM-dd"，可以在 Java 对象的对应日期类型属性上添加注解：

@JsonFormat(pattern="yyyy-MM-dd")
private Date date;

这样，在将 JSON 字符串转换为 Java 对象时，就会按照指定的日期格式进行解析，避免出现日期格式不匹配的错误。
