主要原因是

As you can see in my pom file I have included the hibernate jars. I dont know whats the exact error. Could someone help me? Thanks in advance
正如你在我的 pom 文件中看到的，我已经包含了休眠 jars。我不知道确切的错误是什么。有人可以帮助我吗？提前致谢

Try to declare the dataSourceBean before the sessionFactory
尝试在 sessionFactory 之前声明 dataSourceBean
<bean id="dataSourceBean" class="org.springframework.jdbc.datasource.DriverManagerDataSource">
<property name="driverClassName" value="org.postgresql.Driver"/>
<property name="url" value="jdbc:postgresql://localhost:5432/newdatabase"/>
<property name="username" value="postgres"/>
<property name="password" value="P@ssword"/>

This is dynamic class loading while Bean init! DTD entity Resolver is used while parsing the Spring Bean class while loading into the container. I think the version of your Hibernate is not compatible with your framework and code! Why are you using different hibernate-annotations version?

Are you sure that your Hibernate version is compatible with your Spring framework? Try to change the versions, also check your JVM version you are using to run the Spring server!
