How to add blaze to spring boot project

I tried to add blaze to my spring boot project. I want to use the blaze criteria module. However, I am always getting errors during application startup or initialization of the CriteriaBuilderConfiguration.

On the spring side I am using the following dependencies:

• spring boot: 2.6.7
• spring data: 2.6.7 (comes with spring boot)
• hibernate: 5.6.8.Final (comes with spring boot)
• Java: 11
• blaze: 1.6.6

I added the blaze dependencies as described on this page: https://persistence.blazebit.com/downloads.html

	<dependency>
		<groupId>com.blazebit</groupId>
		<artifactId>blaze-persistence-core-api</artifactId>
		<version>${com.blazebit.blaze-persistence.version}</version>
		<scope>compile</scope>
	</dependency>
	
	<dependency>
		<groupId>com.blazebit</groupId>
		<artifactId>blaze-persistence-core-impl</artifactId>
		<version>${com.blazebit.blaze-persistence.version}</version>
		<scope>runtime</scope>
	</dependency>

	<dependency>
		<groupId>com.blazebit</groupId>
		<artifactId>blaze-persistence-jpa-criteria-api</artifactId>
		<version>${com.blazebit.blaze-persistence.version}</version>
		<scope>compile</scope>
	</dependency>

	<dependency>
		<groupId>com.blazebit</groupId>
		<artifactId>blaze-persistence-jpa-criteria-impl</artifactId>
		<version>${com.blazebit.blaze-persistence.version}</version>
		<scope>runtime</scope>
	</dependency>

With this configuration I get the following exception on creating the CriteriaBuilderFactory (EntityManager is injected by spring):

	CriteriaBuilderConfiguration config = Criteria.getDefault();
	// optionally, perform dynamic configuration
	CriteriaBuilderFactory cbf = config.createCriteriaBuilderFactory(entityManager.getEntityManagerFactory());

Exception:

	java.lang.IllegalArgumentException: No EntityManagerFactoryIntegrator was found on the classpath! Please check if an integration for your JPA provider is visible on the classpath!
	  at com.blazebit.persistence.impl.CriteriaBuilderFactoryImpl.<init>(CriteriaBuilderFactoryImpl.java:82) ~[blaze-persistence-core-impl-1.6.6.jar:1.6.6]
	  at com.blazebit.persistence.impl.CriteriaBuilderConfigurationImpl.createCriteriaBuilderFactory(CriteriaBuilderConfigurationImpl.java:2018) ~[blaze-persistence-core-impl-1.6.6.jar:1.6.6]

I added the dependency to “blaze-persistence-integration-spring-data-2.1” but with the same result. Last I added the hibernate integration (tried 5 and 5.4):

	<dependency>
			<groupId>com.blazebit</groupId>
			<artifactId>blaze-persistence-integration-hibernate-5</artifactId>
			<version>${com.blazebit.blaze-persistence.version}</version>
			<scope>runtime</scope>
	</dependency>

After adding this dependency I the the following error on application startup:

	APPLICATION FAILED TO START
	***************************

	Description:

	An attempt was made to call a method that does not exist. The attempt was made from the following location:

		com.blazebit.persistence.integration.hibernate.Hibernate5MetadataContributor.contribute(Hibernate5MetadataContributor.java:82)

	The following method did not exist:

		'void org.hibernate.boot.internal.MetadataBuildingContextRootImpl.<init>(org.hibernate.boot.spi.MetadataBuildingOptions, org.hibernate.boot.spi.ClassLoaderAccess, org.hibernate.boot.spi.InFlightMetadataCollector)'

	The calling method's class, com.blazebit.persistence.integration.hibernate.Hibernate5MetadataContributor, was loaded from the following location:

	Action:

	Correct the classpath of your application so that it contains compatible versions of the classes com.blazebit.persistence.integration.hibernate.Hibernate5MetadataContributor and org.hibernate.boot.internal.MetadataBuildingContextRootImpl

How to add blaze and blaze criteria to my spring boot project?` Thanks in advance! 😃

It seems it still uses javax. I got the follwoing exception: java.lang.ClassNotFoundException: jakarta.persistence.PersistenceException

After adding the right integration everything works fine:

	  <dependency>
	      <groupId>com.blazebit</groupId>
	      <artifactId>blaze-persistence-integration-hibernate-5.6</artifactId>
	      <version>1.6.6</version>
	  </dependency>`

You can use artifacts suffixed with “-jakarta” if you want to use the jakarta API
