无法使用 jpa+spring boot 创建表

Question

我正在尝试使用 JPA 生成表。但我无法创建它。代码没有错误，但是好像有配置错误。但我找不到它，我尝试了很多配置但没有任何反应。非常感谢。

这是application.property：

spring.datasource.url=jdbc:mysql://localhost:3306/springapp
spring.datasource.username= root
spring.datasource.password= me
spring.datasource.driver-class-name=com.mysql.jdbc.Driver
spring.jpa.hibernate.ddl-auto=create

这是我的课：

@Entity
public class Customer {

    @Id
    @GeneratedValue(strategy=GenerationType.AUTO)
    private int id;
    private String name;
    private String phone;

    public int getId() {
        return id;
    }
    public void setId(int id) {
        this.id = id;
    }
    public String getName() {
        return name;
    }
    public void setName(String name) {
        this.name = name;
    }
    public String getPhone() {
        return phone;
    }
    public void setPhone(String phone) {
        this.phone = phone;
    }
    public Customer(String name, String phone) {
        super();
        this.name = name;
        this.phone = phone;
    }
    public Customer() {
        super();
    }
}

这是应用程序：

@SpringBootApplication
public class Application {

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

这是控制器：

@RestController @RequestMapping("/customer") public class CustomerController { @Autowired CustomerRepository customerRepository;

@RequestMapping("/findall")
@ResponseBody
public List<Customer> findAll() {
    return customerRepository.findAll();
}

}

尝试添加 @EntityScan

@EntityScan("<package with entities>")
@SpringBootApplication 
public class Application { ... }
