Sleep Maven Archetypes Using JPA Annotation Method

Question

Does anyone know where to find or how to set up a sleep mode project from the maven archetype? An important component is the use of the standard JPA annotation method, and not the hibernate method with defining xml mapping files for your entity classes ...

I worked yesterday in the configuration for this and found a useful archetype. standalone-jpa-eclipselink-archetypeUse mvn archetype:generateand select this artifact.

After running the command and creating the project structure in interactive mode, update your pom.xml with this and delete unused classes and configs for derby if you do not want to use derby.

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

With this, you can use JPA annotations and have the correct structure in your project, remember to update persistence.xml to

<?xml version="1.0" encoding="UTF-8" ?>
<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" xmlns="http://java.sun.com/xml/ns/persistence">
    <persistence-unit name="persistenceUnit" transaction-type="RESOURCE_LOCAL">
        <provider>org.hibernate.ejb.HibernatePersistence</provider>
        <class>com</class>
        <exclude-unlisted-classes>false</exclude-unlisted-classes>
        <properties>
            <property name="javax.persistence.jdbc.url" value="jdbc:mysql://localhost:3306/test"/>
            <property name="javax.persistence.jdbc.user" value="root"/>
            <property name="javax.persistence.jdbc.password" value=""/>
            <property name="javax.persistence.jdbc.driver" value="com.mysql.jdbc.Driver"/>

            <property name="hibernate.hbm2ddl.auto" value="create" />
            <property name="hibernate.dialect" value="org.hibernate.dialect.MySQLDialect" />
            <property name="hibernate.show_sql" value="true" />     
        </properties>

    </persistence-unit>
</persistence>
