从前端接收数据反序列化成类,如果时间格式不一致可能会反序列化失败
java
public class StorageDTO implements Serializable {
private static final long serialVersionUID = 1L;
......
//实体类中格式为
@JsonFormat(pattern = "yyyy-MM-dd")
@JsonDeserialize(using = CustomLocalDateTimeDeserializer.class)
@ApiModelProperty("产生时间")
private LocalDateTime generateTime;
}
java
//自定义反序列化类
package com......config;
import com.fasterxml.jackson.core.JsonParser;
import com.fasterxml.jackson.core.JsonProcessingException;
import com.fasterxml.jackson.databind.DeserializationContext;
import com.fasterxml.jackson.datatype.jsr310.deser.LocalDateDeserializer;
import com.fasterxml.jackson.datatype.jsr310.deser.LocalDateTimeDeserializer;
import java.io.IOException;
import java.time.LocalDate;
import java.time.LocalDateTime;
import java.time.format.DateTimeFormatter;
public class CustomLocalDateTimeDeserializer extends LocalDateTimeDeserializer {
private static final long serialVersionUID = 1L;
private static final DateTimeFormatter DEFAULT_FORMATTER = DateTimeFormatter.ISO_LOCAL_DATE_TIME;
private CustomLocalDateTimeDeserializer() {
super(DEFAULT_FORMATTER);
}
public CustomLocalDateTimeDeserializer(DateTimeFormatter formatter) {
super(formatter);
}
@Override
protected LocalDateTimeDeserializer withDateFormat(DateTimeFormatter formatter) {
return new CustomLocalDateTimeDeserializer(formatter);
}
@Override
public LocalDateTime deserialize(JsonParser p, DeserializationContext ctxt) throws IOException, JsonProcessingException {
LocalDate localDate = new LocalDateDeserializer(_formatter).deserialize(p, ctxt);
LocalDateTime localDateTime = localDate.atStartOfDay();
return localDateTime;
}
}后端统一返回格式化后的日期
