考虑在配置中定义一个名为'entityManagerFactory'的bean-Spring Boot [英] Consider defining a bean named 'entityManagerFactory' in your configuration-Spring boot

问题描述

以下是我的代码

Spring boot Entry类

@SpringBootApplication
@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);
    }
}

控制器

@RestController 公共类ShopController {

@RestController public class ShopController {

    @Autowired
    private ShopService shopService;

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

    }

}

实体

@Entity
@Table(name="ShopDetails")
public class Shop {

    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    private int id;
    private String shopName;
    private Address address;

    public String getShopName() {
        return shopName;
    }

    public void setShopName(String shopName) {
        this.shopName = shopName;
    }

    @OneToMany
    @JoinColumn(name="add_Id")
    public Address getAddress() {
        return address;
    }

    public void setAddress(Address address) {
        this.address = address;
    }

    @Override
    public String toString() {
        return "Shop [id=" + id + ", shopName=" + shopName + ", address=" + address + "]";
    }


}

spring数据存储库

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

}

服务等级

@Service
public class ShopService {
    @Autowired
    private ShopRepository shopRepository;

    public void addShopDetails(Shop shop) {
        shopRepository.save(shop);
    }
}

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

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')
}

我知道这个问题已经由某人发布，但是不能解决我的问题，我仍然遇到以下错误，请让我知道这是什么问题

I know this question is already posted by someone but that does not solved my problem I'm still getting the following error ,could you please let me know what is wrong with this

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.

如果我删除排除自动配置，则会出现以下错误

If I remove exclude auto configuration, I got following error

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'entityManagerFactory' defined in class path resource [org/springframework/boot/autoconfigure/orm/jpa/HibernateJpaAutoConfiguration.class]: Invocation of init method failed; nested exception is javax.persistence.PersistenceException: [PersistenceUnit: default] Unable to build Hibernate SessionFactory

推荐答案

如果您关闭自动配置，则应该自己提供.

If you dismiss auto configuration, then you should provide it by yourself.

查看示例:

@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;
}
