问grails 3.3.8。如何解决类型不匹配的错误java.sql.Date属性

EN

   class User {
       String name 
       java.time.LocalTime birthDate
       // etc
   }

def save(User user) {
    user.clearErrors() // this fixed the spurious "property is type-mismatched"
   java.time.LocalDate birthDate = LocalDate.of(params.int('birthDate_year'), params.int("birthDate_month"), params.int("birthDate_day"))
   user.birthDate = birthDate
   userService.save(user)
   :
}

<g:form resource="${this.user}" method="PUT">
    <g:hiddenField name="version" value="${this.user?.version}" />
    <fieldset class="form">
        <f:all bean="user"/>
    </fieldset>
    <fieldset class="buttons">
        <input class="save" type="submit" value="${message(code: 'default.button.update.label', default: 'Update')}" />
    </fieldset>
</g:form>

Cannot cast object '2119-01-02' with class 'java.time.LocalDate' to class 'java.util.Date'

<g:datePicker name="${property}"  precision="day" value="${java.sql.Date.valueOf(value)}" default="none" noSelection="['':'']"/>

cannot resolve which method to invoke for [null] due to overlapping prototypes between: [class java.lang.String] [class java.time.LocalDate]
