如何在SpringBoot/MVC/Web中将String日期转换为ZonedDateTime？_ZonedDateTime - 小郝不负流年

问题：

Field error in object 'saleOrderHeadCriteria' on field 'orderDatetime.greaterThanOrEqual': rejected value [2021-04-16]; codes [typeMismatch.saleOrderHeadCriteria.orderDatetime.greaterThanOrEqual,typeMismatch.orderDatetime.greaterThanOrEqual,typeMismatch.greaterThanOrEqual,typeMismatch.java.time.ZonedDateTime,typeMismatch]; arguments [org.springframework.context.support.DefaultMessageSourceResolvable: codes [saleOrderHeadCriteria.orderDatetime.greaterThanOrEqual,orderDatetime.greaterThanOrEqual]; arguments []; default message [orderDatetime.greaterThanOrEqual]]; default message [Failed to convert property value of type 'java.lang.String' to required type 'java.time.ZonedDateTime' for property 'orderDatetime.greaterThanOrEqual'; nested exception is org.springframework.core.convert.ConversionFailedException: Failed to convert from type [java.lang.String] to type [java.time.ZonedDateTime] for value '2021-04-16'; nested exception is java.lang.IllegalArgumentException: Parse attempt failed for value [2021-04-16]]

解决：

import org.apache.commons.lang.StringUtils;
import org.springframework.boot.context.properties.ConfigurationPropertiesBinding;

import org.springframework.stereotype.Component;
import java.time.LocalDate;
import java.time.ZoneId;
import java.time.ZonedDateTime;
import java.time.format.DateTimeFormatter;
