考慮定義一個配置中的彈簧引導

Question

以下名爲 'entityManagerFactory的' 豆是我的代碼

@EnableJpaRepositories("com.test.assertmanagementdigital4.repositories") 
@EnableAutoConfiguration(exclude = {DataSourceAutoConfiguration.class,HibernateJpaAutoConfiguration.class}) 
@ComponentScan("com.test.assertmanagementdigital4") 
public class AssertManagementDigital4Application { 

    public static void main(String[] args) { 
     SpringApplication.run(AssertManagementDigital4Application.class, args); 
    } 
}

    @RequestMapping(value="/shops",method=RequestMethod.POST) 
    public void shopDetails(@RequestBody Shop shop){ 
     shopService.addShopDetails(shop); 

    } 

}

    } 

    @Override

    } 


} 

彈簧數據儲存庫

@Repository 
public interface ShopRepository extends CrudRepository<Shop,Long>{ 

} 

服務類裏面

application.properties

#spring.datasource.type=org.apache.commons.dbcp.BasicDataSource 
spring.datasource.url:jdbc:h2:mem:testdb;DB_CLOSE_DELAY=-1;DB_CLOSE_ON_EXIT=FALSE 
spring.datasource.username:sa 
spring.datasource.password: 
spring.datasource.driver-class-name:org.h2.Driver 
spring.datasource.platform:h2 

    # enable H2 web console and set url for web console 
    # http://localhost:8080/console 
    spring.h2.console.enabled:true 
    spring.h2.console.path:/console 

的build.gradle

buildscript { 
    ext { 
     springBootVersion = '1.5.4.RELEASE' 
    } 
    repositories { 
     mavenCentral() 
    } 
    dependencies { 
     classpath("org.springframework.boot:spring-boot-gradle-plugin:${springBootVersion}") 
    } 
} 

apply plugin: 'java' 
apply plugin: 'eclipse' 
apply plugin: 'org.springframework.boot' 

version = '0.0.1-SNAPSHOT' 
sourceCompatibility = 1.8 

repositories { 
    mavenCentral() 
} 


dependencies { 
    compile('org.springframework.boot:spring-boot-starter-data-jpa') 
    compile('org.springframework.boot:spring-boot-starter-web') 
    runtime('com.h2database:h2') 
    testCompile('org.springframework.boot:spring-boot-starter-test') 
} 

我知道這個問題已經發表的人，但不解決我的問題，我還是發現了以下錯誤，可能你請讓我知道這有什麼問題

Description: 

Field shopRepository in com.test.assertmanagementdigital4.service.ShopService required a bean named 'entityManagerFactory' that could not be found. 


Action: 

Consider defining a bean named 'entityManagerFactory' in your configuration. 

如果我刪除排除自動配置，我有以下錯誤r

如果您關閉自動配置，那麼您應該自行提供。

見例如：

@Bean 
public LocalContainerEntityManagerFactoryBean entityManagerFactory() throws URISyntaxException { 
    LocalContainerEntityManagerFactoryBean entityManagerFactoryBean = new LocalContainerEntityManagerFactoryBean(); 
    entityManagerFactoryBean.setDataSource(your_datasource); 
    entityManagerFactoryBean.setPackagesToScan(package_to_scan); 
    //additional config of factory 

    return entityManagerFactoryBean; 
} 

@Bean(name = "transactionManager") 
public PlatformTransactionManager jpaTransactionManager(EntityManagerFactory entityManagerFactory) throws URISyntaxException { 
    JpaTransactionManager transactionManager = new JpaTransactionManager(); 
    transactionManager.setEntityManagerFactory(entityManagerFactory); 
    return transactionManager; 
}
