I would start by adding the following dependency:
我将首先添加以下依赖项：
<dependency>
<groupId>org.hibernate</groupId>
<artifactId>hibernate-core</artifactId>
<version>4.1.4.Final</version>
</dependency>
and
和
<dependency>
<groupId>org.hibernate</groupId>
<artifactId>hibernate-entitymanager</artifactId>
<version>5.2.3.Final</version>
</dependency>
UPDATE:Or Simply Add the following dependency.
更新：或者简单地添加以下依赖项。
<dependency>
<groupId>javax.xml.bind</groupId>
<artifactId>jaxb-api</artifactId>
<version>2.3.0</version>
</dependency>

I suspect that the jar files of hibernate-coreand hibernate-entitymanagerdependencies are corrupted or were not installed properly on your machine.
我怀疑 jar 文件hibernate-core和hibernate-entitymanager依赖项已损坏或未在您的计算机上正确安装。
I suggest that you just delete the folders named hibernate-coreand hibernate-entitymanagerfrom your Maven local repositoryand Maven will reinstall them.
我建议您从 Maven 本地存储库中删除名为hibernate-core和的文件夹hibernate-entitymanager，Maven 将重新安装它们。
The default location for Maven local repository is C:\Documents and Settings\[USERNAME]\.m2in windows or ~/.m2in Linux/Mac.
Maven 本地存储库的默认位置C:\Documents and Settings\[USERNAME]\.m2在 Windows 或~/.m2Linux/Mac 中。

I was able to fix the problem by changing the maximum-pool size value from one to two
我能够通过将最大池大小值从 1 更改为 2 来解决该问题
spring.datasource.hikari.maximum-pool-size=2
spring.datasource.hikari.maximum-pool-size=2
回答by JAD
Adding dependencies didn't fix the issue at my end.
添加依赖项并没有解决我最后的问题。
The issue was happening at my end because of "additional" fields that are part of the "@Entity" class and don't exist in the database.
这个问题发生在我的最后，因为“附加”字段是“@Entity”类的一部分并且不存在于数据库中。
I removed the additional fields from the @Entity class and it worked.
我从@Entity 类中删除了其他字段，它起作用了。
Goodluck.
祝你好运。

Try to annotate the class with @EnableTransactionManagement. I was facing the same issue and it got resolved by adding this.
尝试使用@EnableTransactionManagement 注释该类。我遇到了同样的问题，通过添加这个问题得到了解决。

I have gone through similar error. The error was not coming earlier, but recently I reinstall my oracle db and change the instance name from 'xe' to 'orcl', but forget to change this piece of code in property file:
我经历过类似的错误。错误不是更早出现，但最近我重新安装了我的 oracle 数据库并将实例名称从“xe”更改为“orcl”，但忘记更改属性文件中的这段代码：
spring.datasource.driver-class-name=oracle.jdbc.driver.OracleDriver
spring.datasource.url=jdbc:oracle:thin:@localhost:1521:***xe***
spring.datasource.username=system
spring.datasource.password=manager
Once I change it from 'xe' to 'orcl' everything is fine.
一旦我将它从 'xe' 改为 'orcl' 一切都很好。

The problem might be because of package conflicts.
When you use @Idannotation in an entity, it might use the @Idof Spring framework; however, it must use @Idannotation of persistence API.
问题可能是由于包冲突。当您@Id在实体中使用注解时，它可能会使用@IdSpring 框架的；但是，它必须使用@Id持久化 API 的注解。
So use @javax.persistence.Idannotation in entities.
所以@javax.persistence.Id在实体中使用注解。
