spring boot+spring jpa+hibernate 为date类型的属性传入null值报错

1.项目配置

项目框架 spring boot + spring jpa +hibernate

2.情况描述

实体类中存在date类型的字段

@DateTimeFormat(pattern = "yyyy-MM-dd")
@JsonFormat(pattern = "yyyy-MM-dd", timezone = "GMT+8")
@Column(name = "refilme_time")
@Temporal(value = TemporalType.DATE)
private Date refilmdate;
在前端未设置改属性的值，该值默认为null，报如下错误

2021-05-28 17:18:10.893 WARN 9064 --- [nio-7779-exec-2] .w.s.m.s.DefaultHandlerExceptionResolver : Resolved [org.springframework.validation.BindException: org.springframework.validation.BeanPropertyBindingResult: 1 errors

3.解决方案

在controller中为date类型注册customEditor即可

@InitBinder
public void InitBinder(WebDataBinder dataBinder) {
    dataBinder.registerCustomEditor(Date.class, new PropertyEditorSupport() {
        @Override
        public void setAsText(String value) {
            try {
                setValue(new SimpleDateFormat("yyyy-MM-dd").parse(value));
            } catch (ParseException e) {
                setValue(null);
            }
        }

        @Override
        public String getAsText() {
            return new SimpleDateFormat("yyyy-MM-dd").format((Date) getValue());
        }
    });
}
