migrate OpenJPA to Hibernate in spring boot 2.1.7 - spring

Question

I am migrating spring application to spring boot.spring project have JPA implemented with OpenJPA.i need to change it into hibernate.
persistance.xml
<persistence-unit name="PersistenceUnit" transaction-type="RESOURCE_LOCAL">
<provider>org.apache.openjpa.persistence.PersistenceProviderImpl</provider>
<mapping-file>META-INF/queries.xml</mapping-file>
<class>com.dta.abc</class>
<exclude-unlisted-classes>true</exclude-unlisted-classes>
<properties>
<property name="openjpa.Log" value="DefaultLevel=ERROR, Tool=ERROR" />
<property name="openjpa.jdbc.DBDictionary" value="sybase" />
<property name="openjpa.DataCache" value="true" />
</properties>
</persistence-unit>
</persistence>
data-source.xml
<util:map id="sessionSettingsMap">
<entry key="SESSION_SETTINGS_ON" value="set literal_autoparam off"/>
<entry key="SESSION_SETTINGS_OFF" value=""/>
</util:map>
<bean id="sybaseDataSource" class="org.apache.tomcat.jdbc.pool.DataSource" primary="true" >
<property name="driverClassName" value="com.sybase.jdbc3.jdbc.SybDriver" />
</bean>
<bean id="TransactionManager" class="org.springframework.orm.jpa.JpaTransactionManager" primary="true" >
<property name="entityManagerFactory" ref="EntityManagerFactory" />
</bean>
<bean id="openJpaVendorAdapter" class="org.springframework.orm.jpa.vendor.OpenJpaVendorAdapter">
<property name="showSql" value="${connection.show_sql}" />
<property name="generateDdl" value="${connection.generateDdl}" />
<property name="databasePlatform" value="${connection.dialect}" />
</bean>
<bean id="EntityManagerFactory"
class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean" primary="true">
<property name="dataSource" ref="DataSource" />
<property name="jpaVendorAdapter" ref="openJpaVendorAdapter" />
<property name="persistenceUnitName" value="SybaseUnit" />
<property name="jpaProperties">
<props>
<prop key="javax.persistence.query.timeout">90000</prop>
</props>
</property>
<property name="packagesToScan" >
<list>
<value>com.datasource.jpa.dto</value>
</list>
</property>
</bean>
The reason for this migration is Spring Boot2.1.7 does not support OpenJPA
what are the changes need to be done for migrating OpenJPA to hibernate?.
Is there any simplest way for this?
please suggest a valid solution
Edit 1
<util:map id="sessionSettingsMap">
<entry key="SESSION_SETTINGS_ON" value="set literal_autoparam off"/>
<entry key="SESSION_SETTINGS_OFF" value=""/>
</util:map>
<bean id="sybaseDataSource" class="org.apache.tomcat.jdbc.pool.DataSource" primary="true" >
<property name="driverClassName" value="com.sybase.jdbc3.jdbc.SybDriver" />
</bean>
<bean id="TransactionManager" class="org.springframework.orm.jpa.JpaTransactionManager" primary="true" >
<property name="entityManagerFactory" ref="EntityManagerFactory" />
</bean>
<bean id="hibernateJpaVendorAdapter" class="org.springframework.orm.jpa.vendor.HibernateJpaVendorAdapter">
</bean>
<bean id="EntityManagerFactory"
class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean" primary="true">
<property name="dataSource" ref="DataSource" />
<property name="jpaVendorAdapter" ref="hibernateJpaVendorAdapter" />
<property name="persistenceUnitName" value="SybaseUnit" />
<property name="jpaProperties">
<props>
<prop key="javax.persistence.query.timeout">90000</prop>
</props>
</property>
<property name="packagesToScan" >
<list>
<value>com.datasource.jpa.dto</value>
</list>
</property>
</bean>
Now it getting the error
.springframework.beans.factory.BeanCreationException: Error creating bean with name 'sybaseEntityManagerFactory' defined in URL [file:/C:/Users/Administrator/Desktop/Springboot/config/spring/dataso

Im wondering why you are still using xml based configuration. You can config your Hibernate properties in application.properties file and write a configuration class to load all your beans.
You can refer https://howtodoinjava.com/spring-boot2/hibernate-configuration-example/
