在spring boot

Question

我正在尝试在Spring启动应用程序1.4.1中自动配置mysql（最新版​​本是1.4.2，但该版本根本不工作）。我将数据源添加到application.properties：

spring.datasource.url=jdbc:mysql://localhost/transcoder
spring.datasource.username=user
spring.datasource.password=pass
spring.datasource.driver-class-name=com.mysql.jdbc.Driver
spring.jpa.hibernate.ddl-auto=update
spring.jpa.properties.hibernate.dialect = org.hibernate.dialect.MySQL5Dialect

并定义了主要的应用程序

package transcoder;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

@SpringBootApplication
public class TranscoderSpringApplication {

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

我有一个模特：

package transcoder.datasource.model;

import java.io.Serializable;

import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.GenerationType;
import javax.persistence.Id;
import javax.persistence.Table;
import javax.validation.constraints.NotNull;

import lombok.Data;
import lombok.NoArgsConstructor;
import lombok.NonNull;
import lombok.RequiredArgsConstructor;

@Data
@Entity
@RequiredArgsConstructor
@NoArgsConstructor
public class VideoFile implements Serializable {
    private static final long serialVersionUID = -5632175181967653240L;

    @Id
    @GeneratedValue(strategy=GenerationType.IDENTITY)
    private Integer id;
    @NonNull
    @NotNull
    @Column(nullable=false)
    private String filename;
}

和存储库：

package transcoder.datasource.repository;

import java.util.List;

import org.springframework.data.repository.CrudRepository;

import nl.csdigitalmedia.transcoder.datasource.model.VideoFile;

public interface VideoFileRepository extends CrudRepository<VideoFile, Integer> {
    List<VideoFile> findByFilename(String filename);
}

但是当我启动应用程序时，它会给出

***************************
APPLICATION FAILED TO START
***************************

Description:

Method mvcConversionService in org.springframework.web.servlet.config.annotation.WebMvcConfigurationSupport required a bean named 'entityManagerFactory' that could not be found.


Action:

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

我用Google搜索的所有内容都说配置应该有效。

更新（pom.xml）：
