您可以编写自定义解串器为您的班级设置了默认值，以防出现问题.像这样:

You could write a custom deserializer for your class where you set a default value in case something goes wrong. Something like:

public class MyJsonDateDeserializer extends JsonDeserializer<Date>
{
    @Override
    public Date deserialize(JsonParser jsonParser,
            DeserializationContext deserializationContext) throws IOException, JsonProcessingException {

        SimpleDateFormat format = new SimpleDateFormat("dd-MM-yyyy hh:mm:ss");
        String date = jsonParser.getText();
        try {
            return format.parse(date);
        } catch (ParseException e) {
            return new Date();
        }

    }

}

然后在您的课堂上，您可以执行以下操作:

Then on your class you could do something like:

class MyClass {
    //...Fields

    @JsonFormat(shape = JsonFormat.Shape.STRING, pattern = "dd-MM-yyyy hh:mm:ss")
    @JsonDeserialize(using = MyJsonDateDeserializer.class)
    private Date date;

    //...Fields
}

如果您知道不一定总是需要它的值，也可以在类上添加@JsonIgnoreProperties(ignoreUnknown = true).

You could also add @JsonIgnoreProperties(ignoreUnknown = true) over your class if you know that its value is not necessary always.
