Spring Jackson 反序列化Date时遇到的问题

Jackson对于date的反序列化只支持几种，如果不符合默认格式则会报一下错误

 

org.codehaus.jackson.map.JsonMappingException: Can not construct instance of java.util.Date from String value '2012-12-12 12:01:01': not a valid representation (error: Can not parse date "2012-12-12 12:01:01": not compatible with any of standard forms ("yyyy-MM-dd'T'HH:mm:ss.SSSZ", "yyyy-MM-dd'T'HH:mm:ss.SSS'Z'", "EEE, dd MMM yyyy HH:mm:ss zzz", "yyyy-MM-dd"))

解决方案：

 

 

public class CustomJsonDateDeserializer extends JsonDeserializer<Date> {

    @Override
    public Date deserialize(JsonParser jp, DeserializationContext ctxt) throws IOException, JsonProcessingException {
        SimpleDateFormat format = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
                String date = jp.getText();
                try {
                    return format.parse(date);
                } catch (ParseException e) {
                    throw new RuntimeException(e);
                }
    }

}

且在字段的setter上加上注解

 

 

@JsonDeserialize(using = CustomJsonDateDeserializer.class)
