[Spring Boot]控制器需要一个名为“entityManagerFactory”的名称，但找不到该名称

Description:

Field companyResouces in com.loanguruhub.controller.CompanyController required a bean named 'entityManagerFactory' that could not be found.


Action:

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

我被夹在中间。我几乎没试过什么东西。因为提供entityManager的hibernate JPA启动器是从pom中删除hibernate核心和hibernate实体管理器的。xml也是如此。但我也犯了同样的错误。除此之外，我还创建了自定义datasoruce，如下所示。

@Configuration
public class DatabaseConfiguration {
    @Bean
    @ConfigurationProperties("spring.datasource")
    public DataSourceProperties dataSourceProperties() {
        return new DataSourceProperties();
    }

    @Bean
    @ConfigurationProperties("spring.datasource")
    public HikariDataSource dataSource(DataSourceProperties properties) {
        return properties.initializeDataSourceBuilder().type(HikariDataSource.class)
                .build();
    }
}

并试图做同样的事情。但又犯了同样的错误。任何帮助都是值得的。

=======更新========公司控制器代码。

@RestController
@RequestMapping(
        path = "/company",
        produces=MediaType.APPLICATION_JSON_VALUE,
        consumes=MediaType.APPLICATION_JSON_VALUE)
public class CompanyController {
    @Autowired
    private CompanyResources companyResouces;
}

有两件事需要解决，然后就可以工作了。。

因为你使用的是Spring data jpa，所以hibernate是默认实现，所以不需要显式定义hibernate依赖项，因为这可能会产生冲突，所以从pom中删除这个：

   <dependency>
        <groupId>org.hibernate</groupId>
        <artifactId>hibernate-core</artifactId>
        <version> 5.2.1.Final</version>
    </dependency>
    <dependency>
        <groupId>org.hibernate</groupId>
        <artifactId>hibernate-entitymanager</artifactId>
        <version>5.2.3.Final</version>
    </dependency>

因为你也在传递数据源用户名和密码，所以从url中删除传递参数：所以从它中删除用户名和密码spring.datasource.url，只有用户名和密码从spring.datasource.username

从Spring Boot2. xhikari是默认连接池，Spring data jpa将根据应用程序自动配置数据源。

@Configuration
public class DatabaseConfiguration
