JSP Spring eval is parse int (why not parse long)

Question

In a tag i using spring:eval pass Id as ${status.value}, and why spring use parseInt not parseLong ? ps:${status.value} is submission.Id

jsp Tag

<spring:bind path="id">


    <c:if test="${status.value ne null}">
    <spring:eval var="submission" expression="@myService.findById(${status.value})"/>

This is my entity, I am not sure entity will affect spring:eval or not

@Entity
@Cacheable
@Audited
@DynamicInsert
@DynamicUpdate
@DisplayField("testNo")
@Table(name = "test_submission")
public class Submission extends TenantAuditableDynaObjectEntitySupport {

this error

org.springframework.web.servlet.tags.EvalTag.setExpression

this is what I confuse why spring:eval will going parseInt ?

<spring:eval var="submission" expression="@myService.findById(${status.value})"/>

this is my interface

public interface EntityRepository<T extends Entity> extends JpaRepository<T, Long>, DynamicQueryEntityRepository<T> {

    @QueryHints({ @QueryHint(name = "org.hibernate.cacheable", value = "true") })
    T findById(Long id);

this is what my interface extends JpaRepository

package org.springframework.data.jpa.repository;

I am newbie in spring please tell me where i miss to setup or something, thanks.

Do you understand the difference between `serialVersionUID` and `@Id`? — chrylis -cautiouslyoptimistic-, Nov 04 '19 at 04:03
Hi, after i read this https://stackoverflow.com/questions/14274480/static-final-long-serialversionuid-1l I understand thanks for it, but why in tag spring:eval will parseInt not Long or something that is springframework configuration problem or I missunderstanding spring? — Tse Victor, Nov 04 '19 at 05:50
You didn't show the interface for `findById`, in particular what type it expects. — chrylis -cautiouslyoptimistic-, Nov 04 '19 at 05:52
@chrylis-onstrike- hi I edited the code and put interface, but before run interface finById my error will throw it — Tse Victor, Nov 04 '19 at 06:00
It appears that your `status.value` is a string. EL will treat inline numbers as ints unless you put `L` on the end (as in Java source code). The best solution is to fix your `status` object to treat `value` as a `long`; the next best is probably to explicitly insert a `parseLong` call in your expression. — chrylis -cautiouslyoptimistic-, Nov 04 '19 at 06:48
@chrylis-onstrike- wow, When i put L onther end findById(${status.value}L) it is works ! , thank you very much. I will try another 2 best solution as your suggest thank you! have a nice day ~~ — Tse Victor, Nov 04 '19 at 07:26
