Spring MVC中来自LocalDateTime(java 8)的Json字符串

这里回答了类似的问题.您可能需要添加@JsonSerialize(using = LocalDateTimeSerializer.class)到您的字段中.

您还可以创建如下的自定义序列化程序:

public class CustomLocalDateTimeSerializer extends JsonSerializer{

    @Override
    public void serialize(LocalDateTime dateTime, JsonGenerator generator, SerializerProvider sp)
            throws IOException, JsonProcessingException {
        String formattedDateTime = dateTime.format(DateTimeFormatter.ofPattern("yyyy-MM-dd")); 
        generator.writeString( formattedDateTime);
    }

}

并在LocalDateTime字段中使用该自定义序列化程序:

@JsonSerialize(using = CustomLocalDateTimeSerializer.class)
private LocalDateTime w_date;
