converting Hibernate into Spring Data JPA - spring

Question

we have a existing Hibernate application with Spring , we had hbm.xml files but now we want to create a hybrid application of xml and annotation both , so that in future we can move to spring Data jpa
here is my configuration file
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:jee="http://www.springframework.org/schema/jee"
