我正在使用spring数据jpa,hibernate,mysql,tomcat7,maven开发应用程序,这就是创建错误.我想弄明白但是我失败了.

错误是在设置构造函数参数时无法解析对bean'entalManagerFactory'的引用; 没有定义名为'entityManagerFactory'的bean; 注入自动连接的依赖项失败

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'initDbService': Injection of autowired dependencies failed; nested exception is org.springframework.beans.factory.BeanCreationException: Could not autowire field: private org.wahid.cse.repository.RoleRepository org.wahid.cse.service.InitDbService.roleRepository; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'roleRepository': Cannot create inner bean '(inner bean)#c08f81' of type [org.springframework.orm.jpa.SharedEntityManagerCreator] while setting bean property 'entityManager'; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name '(inner bean)#c08f81': Cannot resolve reference to bean 'entityManagerFactory' while setting constructor argument; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No bean named 'entityManagerFactory' …

当我尝试使用 hibernate 和 MySql 运行我的 spring-boot 项目时，出现以下错误。

我创建了一个 Spring Boot 应用程序，并使用我想要执行的方法创建了一个类。将项目部署为 war 文件时，我从堆栈跟踪中收到错误。我想运行 TennisExecutor 类中的方法。

• 没有名为“entityManagerFactory”的可用 bean
• 创建名称为“(inner bean)#366583f9”的 bean 时出错：设置构造函数参数时无法解析对 bean“entityManagerFactory”的引用；嵌套异常是org.springframework.beans.factory.NoSuchBeanDefinitionException：没有名为“entityManagerFactory”的bean可用

我将展示我的代码的一些部分：

@Configuration
@EnableAsync
@EnableScheduling
@ComponentScan(basePackages={"parser", "service", "processing", "automation"})
public class TennisExecutor extends SpringBootServletInitializer {

    @Autowired
    @Qualifier("tennisDataSource")
    private DataSource dataSource;

    @Autowired
    @Qualifier("tennisTm")
    PlatformTransactionManager transactionManager;

    @Autowired
    public ParseUpcomingMatchesFile parseUpcomingMatchesFile;

    @Autowired
    public ParseFinishedMatchesFile parseFinishedMatchesFile;

    @Autowired
    public PlayersProcessor playersProcessor;

    public TennisExecutor() {}

    @Scheduled(cron = "0 */2 * * * ?")
    public void executeTasks() throws IOException {

         parseUpcomingMatchesFile.parseMatchesFile(webDriver, new File(ConstantData.TOMORROW_UPCOMING_MATCHES_FILE_PATH));

     }

@Configuration
@EnableJpaRepositories(basePackageClasses = {ParseUpcomingMatchesFile.class, ParseFinishedMatchesFile.class,
        PlayersProcessor.class}, entityManagerFactoryRef = "tennisEmf", …
