我通过以如下方式调整 build.gradle 文件来解决我的问题：

  buildscript {
 repositories {
 mavenCentral（）
} 
 dependencies {
 classpath（org.springframework.boot：spring-boot- gradle-plugin：1.4.1.RELEASE）
} 
} 

 apply plugin：'java'
 apply plugin：'idea'
 apply插件：'spring-boot'

 jar {
 baseName ='gs-serving-web-content'
 version ='0.1.0'
} 

存储库{
 mavenCentral（）
} 

 sourceCompatibility = 1.8 
 targetCompatibility = 1.8 

依赖关系{
 compile（org.springframework.boot：spring-boot-starter-thymeleaf）
 compile（org.springframework.boot：spring-boot-devtools）
 compile（org.hibernate.ogm：hibernate-ogm-bom：5.0.2.Final）
 compile group ：'org.hibernate.ogm'，名称：'hibernate-ogm-infinispan'，版本：'5.0.2.Final'
编译组：'org.jboss.spec.javax.transaction'，名称：' jboss-transaction-api_1.2_spec'，版本：'1.0.0.Final'

编译组：'org。 'jboss'，名称：'jboss-transaction-spi'，版本：'7.5.0.Final'
编译组：'javax.transaction'，名称：'jta'，版本：'1.1'
编组：'org .hibernate.common'，name：'hibernate-commons-annotations'，version：'5.0.1.Final'

 testCompile（junit：junit）
} 
 

对此的评论：

• 看起来 persistence.xml 被正确拾取，但
  EntitiyManager 无法初始化< provider> HibernateOgmPersistence 正确

因此进行了以下更改： / b>

• 为
  的MongoDB内联添加了 EntitiyManager 的一些依赖关系，内存实例

I am creating an annotation driven Spring MVC application using Intellij 2016 and Gradle. My project structure looks like this:

I deliberately copied the persistence.xml into the folder src/main/java/META-INF/persistence.xml and src/main/resources/META-INF/persistence.xml, but when executing the Gradle bootRun task, I get the following error:

11:18:40: Executing external task 'bootRun'...
:compileJava
:processResources
:classes
:findMainClass
:bootRun
11:18:52.960 [main] DEBUG org.jboss.logging - Logging Provider: org.jboss.logging.Slf4jLoggerProvider
Exception in thread "main" javax.persistence.PersistenceException: No Persistence provider for EntityManager named ogm-jpa-tutorial
    at javax.persistence.Persistence.createEntityManagerFactory(Persistence.java:61)
    at javax.persistence.Persistence.createEntityManagerFactory(Persistence.java:39)
    at my.app.main.Application.main(Application.java:27)
:bootRun FAILED

It seems that the bootRun tasks is not able to pick up the persistence.xml from the classpath.

Does anyone know whats behind that error and has a fix?

EDIT for javaguy, missing init of EntityManager:

/*
Content of the class my.app.main.Application
*/
package my.app.main;

import my.app.controllers.GreetingController;
import my.app.model.Greeting;
import org.hibernate.validator.internal.util.logging.Log;
import org.hibernate.validator.internal.util.logging.LoggerFactory;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.context.annotation.ComponentScan;

import javax.persistence.EntityManager;
import javax.persistence.EntityManagerFactory;
import javax.persistence.Persistence;
import javax.transaction.TransactionManager;

@SpringBootApplication
@ComponentScan({"my.app.*"})
public class Application {

    private static final Log logger = LoggerFactory.make();

    public static void main(String[] args) {

        TransactionManager tm = com.arjuna.ats.jta.TransactionManager.transactionManager();
        EntityManagerFactory emf = Persistence.createEntityManagerFactory("ogm-jpa-tutorial");

        SpringApplication.run(Application.class, args);
    }

}

EDIT for Asterisk Ninja missing persistence.xml:

<?xml version="1.0"?>
<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="ogm-jpa-tutorial" transaction-type="JTA">
        <!-- Use the Hibernate OGM provider: configuration will be transparent -->
        <provider>org.hibernate.ogm.jpa.HibernateOgmPersistence</provider>
        <properties>
            <!-- Here you will pick which NoSQL technology to use, and configure it;
                 in this example we start a local in-memory Infinispan node. -->
            <property name="hibernate.ogm.datastore.provider" value="infinispan"/>
        </properties>
    </persistence-unit>
</persistence>

EDIT, missing build.gradle:

buildscript {
    repositories {
        mavenCentral()
    }
    dependencies {
        classpath("org.springframework.boot:spring-boot-gradle-plugin:1.4.1.RELEASE")
    }
}

apply plugin: 'java'
apply plugin: 'idea'
apply plugin: 'spring-boot'

jar {
    baseName = 'gs-serving-web-content'
    version =  '0.1.0'
}

repositories {
    mavenCentral()
}

sourceCompatibility = 1.8
targetCompatibility = 1.8

dependencies {
    compile("org.springframework.boot:spring-boot-starter-thymeleaf")
    compile("org.springframework.boot:spring-boot-devtools")
    compile("org.hibernate.ogm:hibernate-ogm-bom:5.0.2.Final")
    compile group: 'org.hibernate.javax.persistence', name: 'hibernate-jpa-2.1-api', version: '1.0.0.Final'
    compile group: 'javax.transaction', name: 'jta', version: '1.1'

    compile group: 'org.jboss.narayana.jta', name: 'narayana-jta', version: '5.3.5.Final'
    compile group: 'org.hibernate', name: 'hibernate-annotations', version: '3.5.6-Final'

    testCompile("junit:junit")
}

I solved my problem by adapting the build.gradle file in the following fashion:

buildscript {
repositories {
    mavenCentral()
}
dependencies {
    classpath("org.springframework.boot:spring-boot-gradle-plugin:1.4.1.RELEASE")
}
}

apply plugin: 'java'
apply plugin: 'idea'
apply plugin: 'spring-boot'

jar {
    baseName = 'gs-serving-web-content'
    version =  '0.1.0'
}

repositories {
    mavenCentral()
}

sourceCompatibility = 1.8
targetCompatibility = 1.8

dependencies {
    compile("org.springframework.boot:spring-boot-starter-thymeleaf")
    compile("org.springframework.boot:spring-boot-devtools")
    compile("org.hibernate.ogm:hibernate-ogm-bom:5.0.2.Final")
    compile group: 'org.hibernate.ogm', name: 'hibernate-ogm-infinispan', version: '5.0.2.Final'
    compile group: 'org.jboss.spec.javax.transaction', name: 'jboss-transaction-api_1.2_spec', version: '1.0.0.Final'
    compile group: 'org.hibernate.javax.persistence', name: 'hibernate-jpa-2.1-api', version: '1.0.0.Final'
    compile group: 'org.jboss.narayana.jta', name: 'narayana-jta', version: '5.3.5.Final'
    compile group: 'org.jboss', name: 'jboss-transaction-spi', version: '7.5.0.Final'
    compile group: 'javax.transaction', name: 'jta', version: '1.1'
    compile group: 'org.hibernate.common', name: 'hibernate-commons-annotations', version: '5.0.1.Final'

    testCompile("junit:junit")
}

Comment on that:

• It seems that the persistence.xml was picked up correctly, but the EntitiyManager could not initialize the <provider>HibernateOgmPersistence correctly

therefore the following changes were done:

• added some dependencies for the EntitiyManager specific for the MongoDB in-memory instance
