Hibernate + JPA + Spring-data-jpa + HANA Database

In my previous post we have created a HANA Database(Row) and we have created a Web application to create and see the Users with MySQL

Now lets change the application to work with HANA DB and In SAP HANA Cloud Platform.

1: We need to Access the Database Using JNDI Data Source, Change the Data Source Name as below in the HibernateConfig.java (see the post User App With MySQL)

 public DataSource getDataSource() {
 final JndiDataSourceLookup dsLookup = new JndiDataSourceLookup();
 DataSource dataSource = dsLookup.getDataSource("jdbc/DefaultDB");
 return dataSource;

If You are using the HANA Cloud Trail Version we can create only one DataSource that is so the datasource name should be “jdbc/DefaultDB”, other name will not be considered. (Creating the Datasource Name(binding) for the HANA Database we will see in the next step).

2: Change the Hibernate Dialect in the hibProperties() method in the  HibernateConfig.java (see the post User App With MySQL)

Properties properties = new Properties();

Dialect is “org.hibernate.dialect.HANARowStoreDialect” Because we have created Row Databse.

hibernate.default_schema should be Database user name which we have created for the Database(refer my previous post ), because the HANA will create the Schema in the USERNAME. I think its only for Trail version.

3: We need to Create the (Data Source Bindings) for the HANA Database.

To do this first we need to deploy the Java application first. follow the post to Deploy the Java web application.

After deploying the application login to the SAP HANA Cloud Platform Cockpit

  1. Click on the “Databases & Schemas”, select the Database which you need to bind for this application
  2. Now we can see the overview screen
  3. Select “Data Source Bindings” from the left navigation panel.
  4. click on “New binding”binding
  5. Data source name Should be , see the Step 1.
  6. select the Java Application
  7. Give the user name which is created in the previous post.
  8. password for the User.

Need to restart the Java Application to take new binding.
