Spring boot 带有Spring引导的ObjectDB

我想将Spring引导应用程序配置为使用ObjectDB持久性而不是默认的Hibernate，但我无法这样做。由于ObjectDB已经是JPA提供程序，我需要排除任何涉及数据源、JDBC或Hibernate的自动配置

到目前为止，我在Application.java中有以下内容：

@Configuration
@EnableAutoConfiguration(exclude={HibernateJpaAutoConfiguration.class})
@ComponentScan
public class Application {

    public static void main(String[] args) {
        SpringApplication.run(Application.class, args);
    }

    @Bean
    @Primary
    public EntityManagerFactory entityManagerFactory() {
        return Persistence.createEntityManagerFactory("test.odb");
    }
}

和build.gradle：

dependencies {
    compile('org.springframework.cloud:spring-cloud-starter-oauth2')
    compile('org.springframework.boot:spring-boot-starter-security')
    compile('org.springframework.boot:spring-boot-starter-data-jpa') {
        exclude module: 'hibernate-entitymanager' //by artifact name
    }
    compile('org.springframework.boot:spring-boot-starter-web')
    compile('org.springframework.boot:spring-boot-starter-tomcat')
    compile('com.objectdb:objectdb:2.6.5')
    compile('org.eclipse.persistence:javax.persistence:2.1.0')
}

dependencies {
    compile('org.springframework.cloud:spring-cloud-starter-oauth2')
    compile('org.springframework.boot:spring-boot-starter-security')
    compile('org.springframework.boot:spring-boot-starter-web')
    compile('org.springframework.boot:spring-boot-starter-tomcat')

    // Needed to exclude these when using objectdb
    compile('org.springframework.boot:spring-boot-starter-data-jpa') {
        exclude module: 'spring-boot-starter-jdbc' //by artifact name
        exclude module: 'hibernate-entitymanager' //by artifact name
    }
    compile('com.objectdb:objectdb:2.6.5')
    compile('org.eclipse.persistence:javax.persistence:2.1.0')
}

但是，当使用以下异常提取启动应用程序时，此操作失败：

Caused by: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'dataSourcePublicMetrics': Invocation of init method failed; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'dataSource' defined in class path resource [org/springframework/boot/autoconfigure/jdbc/DataSourceAutoConfiguration$NonEmbeddedConfiguration.class]: Bean instantiation via factory method failed; nested exception is org.springframework.beans.BeanInstantiationException: Failed to instantiate [javax.sql.DataSource]: Factory method 'dataSource' threw exception; nested exception is org.springframework.beans.factory.BeanCreationException: Cannot determine embedded database driver class for database type NONE.

Spring Boot似乎试图创建一个“PublicMetrics”bean，该bean包含有关数据源的信息，但未能创建数据源，因为ObjectDB是一个面向对象的数据库，而不是SQL数据库，所以它不提供任何数据源

如何完全禁用PublicMetrics

---

我已经尝试过了，但没有成功，如果我从依赖项中排除“spring boot starter jdbc”，那么我的spring数据存储库由于某种原因不会被实例化。

无论如何，我发现我只需要排除jdbc依赖项并显式添加@EnableJpaRepositories注释即可使存储库正常工作

以下是工作配置：

Application.java

@SpringBootApplication
@EnableJpaRepositories // Needed when using objectdb
public class Application {

    public static void main(String[] args) {
        SpringApplication.run(Application.class, args);
    }

    // Needed when using objectdb
    @Bean
    public EntityManagerFactory entityManagerFactory() {
        return Persistence.createEntityManagerFactory("test.odb");
    }

    // Needed when using objectdb
    @Bean(name = "transactionManager")
    public PlatformTransactionManager transactionManager() {
        return new JpaTransactionManager(entityManagerFactory());
    }
}

build.gradle：

dependencies {
    compile('org.springframework.cloud:spring-cloud-starter-oauth2')
    compile('org.springframework.boot:spring-boot-starter-security')
    compile('org.springframework.boot:spring-boot-starter-data-jpa') {
        exclude module: 'hibernate-entitymanager' //by artifact name
    }
    compile('org.springframework.boot:spring-boot-starter-web')
    compile('org.springframework.boot:spring-boot-starter-tomcat')
    compile('com.objectdb:objectdb:2.6.5')
    compile('org.eclipse.persistence:javax.persistence:2.1.0')
}

dependencies {
    compile('org.springframework.cloud:spring-cloud-starter-oauth2')
    compile('org.springframework.boot:spring-boot-starter-security')
    compile('org.springframework.boot:spring-boot-starter-web')
    compile('org.springframework.boot:spring-boot-starter-tomcat')

    // Needed to exclude these when using objectdb
    compile('org.springframework.boot:spring-boot-starter-data-jpa') {
        exclude module: 'spring-boot-starter-jdbc' //by artifact name
        exclude module: 'hibernate-entitymanager' //by artifact name
    }
    compile('com.objectdb:objectdb:2.6.5')
    compile('org.eclipse.persistence:javax.persistence:2.1.0')
}
