堆栈内存溢出
  简体   繁体   English

出于某种奇怪的原因，我无法运行我的JPA代码。“长度不能为负。”

[英]For some odd reason, I can't run my JPA code.. “The length cannot be negative.”

问题描述

I got this wierd bug, when i'm trying to add an record to my database, using JPA. 当我尝试使用JPA将记录添加到数据库时，出现了一个奇怪的错误。 I've previous used the same technique to add other records in different tables.. I do not understand the error i've gotten. 我以前使用过相同的技术将其他记录添加到不同的表中。.我不明白我得到的错误。

Following code: 以下代码： 

@Override
    public void assignHelpRequest(HelpRequestDetails helprequest, int userID) {
        //Helpreply reply = new Helpreply(Integer.MAX_VALUE, "", "", new Date());
        Helpreply reply = new Helpreply();
        reply.setRequestID(em.find(Helprequest.class, helprequest.getRequestID()));
        reply.setUserID(em.find(Users.class, userID));
        em.persist(reply);

        Helprequest request = em.find(Helprequest.class, helprequest.getRequestID());
        request.setStatus(1);
        em.merge(request);

Thanks for the comments I got. 感谢您的评论。

What i needed to get rid of the errors was to remove 我需要摆脱的错误是删除 

@Size(min = 1, max = 0)

From my entity class. 从我的实体课。 This was the the reason for the error I got. 这就是我得到错误的原因。 I think it explain it self, why it didn't work :-) 我认为它可以自我解释，为什么不起作用:-)
