springboot 提交时间字符串报错 Failed to convert property value of type ‘java.lang.String‘ to required ‘Date‘

Field error in object 'accountPeriod' on field 'endDate': rejected value [2021-12-31]; codes [typeMismatch.accountPeriod.endDate,typeMismatch.endDate,typeMismatch.java.util.Date,typeMismatch]; arguments [org.springframework.context.support.DefaultMessageSourceResolvable: codes [accountPeriod.endDate,endDate]; arguments []; default message [endDate]]; default message [Failed to convert property value of type 'java.lang.String' to required type 'java.util.Date' for property 'endDate'; nested exception is org.springframework.core.convert.ConversionFailedException: Failed to convert from type [java.lang.String] to type [@com.fasterxml.jackson.databind.annotation.JsonSerialize @javax.persistence.Temporal @javax.persistence.Column java.util.Date] for value '2021-12-31'; nested exception is java.lang.IllegalArgumentException]
Field error in object 'accountPeriod' on field 'startDate': rejected value [2021-12-11]; codes [typeMismatch.accountPeriod.startDate,typeMismatch.startDate,typeMismatch.java.util.Date,typeMismatch]; arguments [org.springframework.context.support.DefaultMessageSourceResolvable: codes [accountPeriod.startDate,startDate]; arguments []; default message [startDate]]; default message [Failed to convert property value of type 'java.lang.String' to required type 'java.util.Date' for property 'startDate'; nested exception is org.springframework.core.convert.ConversionFailedException: Failed to convert from type [java.lang.String] to type [@com.fasterxml.jackson.databind.annotation.JsonSerialize @javax.persistence.Temporal @javax.persistence.Column java.util.Date] for value '2021-12-11'; nested exception is java.lang.IllegalArgumentException]

解决方法：

如:  
@DateTimeFormat(pattern = "yyyy-MM-dd HH:mm:ss")
@Column(name = "LOGIN_TIME")
private Date loginTime;

刚才发现，如果转换的时间格式定义为 "yyyy-MM-dd HH:mm:ss"，

那页面传到后台的字符串是这种格式的："2019-01-31 14:33"，后台还是会报错，因为字符串里没有 秒 的数据。

    @InitBinder
    public void initBinder(WebDataBinder binder) {
        SimpleDateFormat dateFormat = new SimpleDateFormat("yyyy-MM-dd");
        dateFormat.setLenient(true);
        // true:允许输入空值，false:不能为空值
        binder.registerCustomEditor(Date.class, new CustomDateEditor(dateFormat, true));
    }

如下图所示：
