Integration of Spring and JPA

1)Create Persistence and place in META-INF folder

      <?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<persistence version="2.0"
xsi:schemaLocation="http://java.sun.com/xml/ns/persistence
                                 http://java.sun.com/xml/ns/persistence/persistence_2_0.xsd
                                 http://java.sun.com/xml/ns/persistence/orm http://java.sun.com/xml/ns/persistence/orm_2_0.xsd"
xmlns:orm="http://java.sun.com/xml/ns/persistence/orm" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns="http://java.sun.com/xml/ns/persistence">
<persistence-unit name="tscUnit1" transaction-type="RESOURCE_LOCAL">
<provider>org.hibernate.jpa.HibernatePersistenceProvider</provider>
<class>com.tutorialspoint.models.Stock</class>
<class>com.tutorialspoint.models.StockDailyRecord</class>
<exclude-unlisted-classes />
<properties>
        <property name="hibernate.dialect" value="org.hibernate.dialect.MySQLDialect" />
<property name="hibernate.hbm2ddl.auto" value="update" />
<property name="hibernate.show_sql" value="true" />
</properties>
</persistence-unit>
</persistence>
