Need to configuration steps for play2+hibernate(JPA)+mySQL

[gsp]

Hi,

This is siva, I am newly learning playframe work , I am trying to connect play 2.0 project with mySQL database by using hibernate(JPA). Still I didn't get solution. Could you tell exact steps for that configuration or could you share that project to me.

Hi Siva,

 You need to add mysql configuration stuff in floder conf/application.conf file.I have given the stuff u just copy and paste.

db.default.driver=com.mysql.jdbc.Driver
db.default.user=root
db.default.pass=root
db.default.url="jdbc:mysql://localhost/databasename".

Hi Gopala,

Thank you for response.

I want to steps for play2+jpa+mysql

I configured MySQL db details,

 conf/application.conf

----------------------------------

db.default.driver=com.mysql.jdbc.Driver

db.default.url="jdbc:mysql://182.897:3456/mydb"

db.default.user=****

db.default.password=****

db.default.jndiName=DefaultDS

jpa.default=defaultPersistenceUnit

Build.scala

---------------

"org.hibernate" % "hibernate-entitymanager" % "3.6.9.Final",

      "mysql" % "mysql-connector-java" % "5.1.18"

persistence.xml

-----------------------

<persistence xmlns="http://java.sun.com/xml/ns/persistence"

             xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

             xsi:schemaLocation="http://java.sun.com/xml/ns/persistence http://java.sun.com/xml/ns/persistence/persistence_2_0.xsd"

        <properties>

            <property name="hibernate.dialect" value="org.hibernate.dialect.MySQLInnoDBDialect"/>

        </properties>

    </persistence-unit>

    

</persistence>

I am trying to run my application I got Unexpected exception:

                      PersistenceException: [PersistenceUnit: defaultPersistenceUnit] Unable to build EntityManagerFactory

No source available, here is the exception stack trace:

Hi Nilanjan,

Thank you for response.

I am trying jpa with play frame work.

Could u give any sample app for play+jpa+mysql.

[Leonard Punt]

Play has a sample of JPA+H2: https://github.com/playframework/Play20/tree/master/samples/java/computer-database-jpa

Is the stacktrace you posted the whole stacktrace? If not, can you provide the whole stacktrace?

Hi  Leonard Punt,

Thank you for response.

I am trying to configure play2.0+mysql+jpa.

Could you tell configurations steps for mysql+jpa

This is how to configure Play 2 + Hibernate + MySQL. If you are using a different JPA implementation, some steps will probably be slightly different.

1. conf/application.conf:

db.default.driver=com.mysql.jdbc.Driver
db.default.url="jdbc:mysql://localhost/database_name"
db.default.user=mysql_user
db.default.password=mysql_user_password

2. project/Build.scala:

val appDependencies = Seq(
    		"org.hibernate" % "hibernate-entitymanager" % "3.6.9.Final",

    		"mysql" % "mysql-connector-java" % "5.1.18"

3. conf/META-INF/persistence.xml:

<persistence xmlns="http://java.sun.com/xml/ns/persistence"
             xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance

"
             xsi:schemaLocation="http://java.sun.com/xml/ns/persistence http://java.sun.com/xml/ns/persistence/persistence_2_0.xsd"
             version="2.0">
             
    <persistence-unit name="defaultPersistenceUnit" transaction-type="RESOURCE_LOCAL">
        <provider>org.hibernate.ejb.HibernatePersistence</provider>
        <non-jta-data-source>DefaultDS</non-jta-data-source>
        <properties>
            <property name="hibernate.dialect" value="org.hibernate.dialect.MySQL5Dialect"/>
            <property name="hibernate.hbm2ddl.auto" value="update"/>
        </properties>
    </persistence-unit>
    
</persistence>

4. Annotate your Controller methods with:

@play.db.jpa.Transactional

or

@play.db.jpa.Transactional(readOnly = true)

5. Annotate your Model classes with

@javax.persistence.Entity

thanks Leonard, your post did it for me. Looked for hours, this worked for me.

I am also running into this problem with Play 2.1 java

Please give some suggestion.

Thanks in advance. :)

[Marcos Pereira]

I think that is better look at the stack trace in your console. Maybe there is more information there. Also, could you give us more details about how are you configuring your app to use jpa?

Hi,

We have selected play2.1, scala 2.1.0 and hibernate for a large enterprise product's backend REST services development. Can you please suggest if we have choosen the right technologies? about using Scala and Hibernate, and also can you please show a good sample configuration for Play2.1, Scala 2.1.0 and Hibernate, MySQL project.

Any help would be greatly appreciated.

Thanks,

Hi, I have created a basic sample for the configuration of Play 2.1.1 Framework, Scala 2.10 Language, Spring3 for dependency injection and Hibernate4 as ORM.

Log4j.jar is used for logging.

Checkout the project : https://github.com/ceecer1/play211-scala210-spring3-Hibernate4.git

Edit the following to suit your db requirement in spring-context-data.xml.

<bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource" destroy-method="close">
        <property name="driverClassName" value="org.postgresql.Driver"/>
        <property name="url" value="jdbc:postgresql://localhost:5432/scalaspringhibernate"/>
        <property name="username" value="test"/>
        <property name="password" value="test"/>
    </bean>

cmd -> play run

Creates tables in the database.

Insert 1 or 2 rows manually in the User table after the db is created.

Change <prop key="hibernate.hbm2ddl.auto">

create</prop> to update

got to : http://localhost:9000/ and see the JSON result

This might be really helpful for you guys.

Enjoy SCALA.

Thanks,

Hi!

I was having the same problem as you!

Although the dependency "javaJpa" was in the "Build.scala" file, i wasn't able to use the play.db.jpa.JPA helper, so i tried to follow the j2ee 6 official tutorial (http://docs.oracle.com/javaee/6/tutorial/doc/bnbpy.html).

Following the tutorial those problems occurred.

All the examples are using the JPA helper, so i needed to use too. So i cleaned the project, forced the application to update the dependencies (using play update) and then i was able to use the JPA helper.

Using the helper those errors disappeared.

Clean the project, force the update of the dependencies and use the JPA helper!

In the worst case clean the sbt dependencies or create a new play installation folder.

Now i've got others, but it's my fault!

I hope it helps!

Hi Sivaprasad,

Play 2.5.3 + Spring Data Jpa

To have play and mysql working together using spring data jpa we ca do these tweak in our code,

1. First we need to have persistant unit for mysql. We can follow the official play documentation for that,
2. Then we can have repository which is built using play spring data jpa,
3. and finally the most important we can inject the repository implementation using Spring Guice injection  module.

I have done this in this ( https://github.com/beingsagir/play-java-spring-data-jpa ) open source project which you can fork and explore further. Let me know if you face any issue and create issue in the Github.
