ObjectDB與彈簧啓動

我想配置一個Spring Boot應用程序使用ObjectDB持久性而不是默認的Hibernate，但我無法這樣做。由於ObjectDB已經是JPA提供者，我需要排除涉及DataSource，JDBC或Hibernate的任何自動配置。ObjectDB與彈簧啓動

到目前爲止，我已經中Application.java如下：

@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"); 
    } 
}

而且的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') 
}

但是開始出現以下異常提取物中的應用程序時失敗

Spring Boot似乎試圖創建一個「PublicMetrics」bean h有關於數據源的信息，然後無法創建數據源，因爲ObjectDB是面向對象的數據庫，而不是SQL，所以它不提供任何數據源。

如何禁用PublicMetrics？

我已經試過http://www.objectdb.com/database/forum/860沒有成功，如果我從依賴項中排除「spring-boot-starter-jdbc」，那麼我的Spring Data存儲庫不會由於某種原因而被實例化。

沒關係，我發現我只需要排除jdbc依賴關係，並顯式添加@EnableJpaRepositories註釋以使存儲庫工作。

這裏的工作配置：

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()); 
    } 
}

的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-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') 
}
