So my actual error seem to be something with the ID′s in the database and whats being updated. In my GET method I am getting the current ID which in this case is 10.
所以我的实际错误似乎与数据库中的 ID 以及正在更新的内容有关。在我的 GET 方法中，我获得了当前 ID，在这种情况下是 10。
@Autowired
PersonService service;
@RequestMapping(method = RequestMethod.GET)
public ModelAndView index(@PathVariable int id) {
EditPersonBean bean = new EditPersonBean();
if (id > 0) {
Person person = service.getPerson(id);
bean.copyValuesToBean(person);
}
ModelAndView mav = new ModelAndView("editPerson");
mav.addObject("editPersonBean", bean);
return mav;
}
But in my post method this ID that was 10 is suddenly 0 which I belive might be the cause of this error?
但是在我的 post 方法中，这个 10 的 ID 突然变成了 0，我认为这可能是导致此错误的原因？
@RequestMapping(value = "/edit", method = RequestMethod.POST)
public String save (EditPersonBean bean, Person person, @RequestParam(value = "file", required = false) MultipartFile file) {
System.out.println("incoming id : " + bean.getId());
try {
Blob blob = Hibernate.createBlob(file.getInputStream());
bean.copyBeanValuesToPerson(person,blob);
service.updatePerson(person);
} catch (IOException e) {
e.printStackTrace();
}
return "redirect:/person.html";
}
What then could be the cause of this or is the error something else?
那么这可能是什么原因或者是其他错误？

The only way to exactlyknow what is happening is to turn on Hibernate statement logging in your Hibernate.cfg.xml configuration. That is because none of the line numbers in the stack trace correspond with the part of your code that performed the actual Hibernate operation. Instead, the operations are batched and then executed all at once upon transaction close (or after a specified number of operations have been batched).
确切知道发生了什么的唯一方法是在 Hibernate.cfg.xml 配置中打开 Hibernate 语句日志记录。那是因为堆栈跟踪中的行号都与执行实际 Hibernate 操作的代码部分相对应。相反，这些操作是批处理的，然后在事务关闭时（或在批处理了指定数量的操作后）立即执行。
To enable Hibernate statement logging,
要启用 Hibernate 语句日志记录，
<property name="show_sql">true</property>
<property name="format_sql">true</property>
<property name="use_sql_comments">true</property>
That said, last time I ran into this issue, it was a case of a record being deleted by general HQL update in a different thread/transaction, then the current thread/transaction trying to delete the exact same record by ID. Unfortunately since the transaction is batched you don't see it at the point you did the delete but, rather, at some point way later in the program execution. Thus the need to turn on statement logging to see which actual Hibernate operation triggered the exception.
也就是说，上次我遇到这个问题时，是一个记录被不同线程/事务中的常规 HQL 更新删除，然后当前线程/事务尝试按 ID 删除完全相同的记录。不幸的是，由于事务是批处理的，因此您在执行删除时看不到它，而是在程序执行后期的某个时间点看到它。因此需要打开语句日志以查看哪个实际的 Hibernate 操作触发了异常。
回答by David Fischer
This error usually caused when the hibernate can't find all the rows it needs to update. Meaning that when you try to update some objects that were pulled from the DB they don't really exist anymore (or never existed in the first place).
当休眠无法找到它需要更新的所有行时，通常会导致此错误。这意味着当您尝试更新从数据库中提取的某些对象时，它们实际上不再存在（或者根本就不存在）。
It might be because another thread is deleting them or that the DB's isolation mode is set to read_uncommited and so rows that were created by another transaction failed to save (due to a transaction failure) and don't exist anymore.
这可能是因为另一个线程正在删除它们，或者数据库的隔离模式设置为 read_uncommited，因此另一个事务创建的行无法保存（由于事务失败）并且不再存在。

Just type saveinstead of saveOrUpdatein your hibernate query. This is due to previous logs your class is generating some other ID which was previously stored in your table. So hibernate tries to update with same ID and it finds no row with that ID so it gives a staleStateException.
只需键入save而不是saveOrUpdate在您的休眠查询中。这是由于您的班级之前的日志生成了之前存储在您的表中的一些其他 ID。因此，hibernate 尝试使用相同的 ID 进行更新，但没有找到具有该 ID 的行，因此它给出了staleStateException.

I ran into similar problem, where I was trying to save an object where his id was a primitive field (long), and at the time of create the object, the id was set to 0 by default, and Hibernate assumed I wanted to update the row with id = 0 (which obviously doesn't exist).
我遇到了类似的问题，我试图保存一个对象，其中他的 id 是一个原始字段（长），并且在创建对象时，id 默认设置为 0，Hibernate 假设我想更新id = 0 的行（显然不存在）。
My solution was change the id field to Long (wrapper), and that way, when I create a new instance the id is set to null, and Hibernate understands I am inserting a new element to the database.
I hope it helps. Thanks.
我的解决方案是将 id 字段更改为 Long（包装器），这样，当我创建一个新实例时，id 设置为 null，Hibernate 知道我正在向数据库中插入一个新元素。
我希望它有帮助。谢谢。

100 % Solution : 1 make sure id in table is auto increment all your foreign keys are not null scope is session
100% 解决方案：1 确保表中的 id 是自动递增的所有外键都不为空范围是会话

add a cascadefor update. will solve the issue if foreign keys are involved.
添加级联进行更新。如果涉及外键，将解决问题。

I got this error because I wanted to update data and I used
service.update(user);
But then for testing purpose I cleared the User table and forgot to change the method to
service.saveOrUpdate(user);
Thus I changed it and the issue was solved.
我收到此错误是因为我想更新数据并且我使用了
服务.更新（用户）；
但是为了测试目的，我清除了 User 表并忘记将方法更改为
service.saveOrUpdate(用户);
因此，我对其进行了更改，问题解决了。

some Times we use generator class to generate primary key of a row... but we add it force in program at time we will get stalestateException.
有时我们使用生成器类来生成一行的主键……但是我们在程序中强制添加它，我们会得到 stalestateException。
student=new Student();
student.setId(4);
student.setName("thatha");
student.setDept("dev");
try {
transaction = session.beginTransaction();
session.save(student);
transaction.commit();
System.out.println("student is updated");
} catch (HibernateException e) {
e.printStackTrace();
transaction.rollback();
System.out.println("tx is rollback");
}
回答by Bhuvanesh s
Check if the variable of the Object, that is mapped to the hibernate as Id (which uses a generator class) is not containing any stale value in the first place.
首先检查对象的变量，即映射到休眠状态的 Id（使用生成器类）是否不包含任何过时的值。
If the record is been deleted by any another thread or operation, but your Id variable is still containing the stale value and when you go for updating the record in the DB, it gives you this exception as there will be no record for the given id in the DB and hence you will have to save the object instead of updating, as there is no scope for updating the record in the first place
如果记录已被任何其他线程或操作删除，但您的 Id 变量仍包含陈旧值，并且当您去更新数据库中的记录时，它会为您提供此异常，因为给定 id 将没有记录在数据库中，因此您必须保存对象而不是更新，因为首先没有更新记录的范围
Or else
要不然
Set the id as null when your are using saveOrUpdate method.
使用 saveOrUpdate 方法时将 id 设置为 null。
