jar file for JPA 2.0

import javax.persistence.crit开发者_如何转开发eria.CriteriaBuilder;
import javax.persistence.criteria.CriteriaQuery;
import javax.persistence.criteria.Root;

I've created a JPA project where I try to user the above classes but I'm unable to find what jar I'm missing for them. Please guide me.

Try the Geronimo specs JPA2 jar http://mirrors.ibiblio.org/pub/mirrors/maven2/org/apache/geronimo/specs/geronimo-jpa_2.0_spec/1.0-PFD2/ There is still no official JPA2.jar

EclipseLink provides the JPA 2.0 Reference Implementation which is officially out since Java EE 6 is out. You'll find these classes in the jars bundled in eclipselink-2.0.0.v20091127-r5931.zip. If you are looking for a Maven repo, have a look at this page.

A slightly better answer (since 2011) is to use the one from maven central, i.e.,

org.hibernate.javax.persistence:hibernate-jpa-2.0-api:1.0.1-Final

OR

<groupId>org.hibernate.javax.persistence</groupId>
<artifactId>hibernate-jpa-2.0-api</artifactId>
<version>1.0.1.Final</version>

See: http://repo1.maven.org/maven2/org/hibernate/javax/persistence/hibernate-jpa-2.0-api/1.0.1.Final/

For all the available versions, especially the latest, see http://repo1.maven.org/maven2/org/hibernate/javax/persistence/hibernate-jpa-2.0-api/

Here is hibernate-jpa-2.0

http://repository.jboss.org/maven2/org/hibernate/javax/persistence/hibernate-jpa-2.0-api/1.0.0.Final/

These files are found in the javax.persistence jar file. The Eclipse version of the javax.persistence jar file can be found on Maven Central. Or you can add the following dependency in your project's pom.xml file to get Maven to pull it down for you.

    <dependency>
        <groupId>org.eclipse.persistence</groupId>
        <artifactId>javax.persistence</artifactId>
        <version>2.1.1</version>
        <scope>compile</scope>
    </dependency>
