我创建的项目：http://start.spring.io/ 我用maven构建它，它正在运行。Spring Boot Vaadin7集成 - 无法绑定@Autowired
所以我创建实体的人：
@Entity
public class Person implements Serializable {
private static final long serialVersionUID = 1L;
@Id
@GeneratedValue(strategy = GenerationType.AUTO)
private long id;
@Temporal(TemporalType.TIMESTAMP)
private Date birthDay;
@NotNull(message = "Name is required")
@Size(min = 3, max = 50, message = "Name must be longer than 3 and less than 40 characters")
private String name;
private Boolean colleague;
private String phoneNumber;
@NotNull(message = "Email is required")
@Pattern(regexp = "[email protected]+\\.[a-z]+", message = "Must be valid email")
private String email;
//----- GETTERS AND SETTERS -----------
}
对于这个实体林创建库PersonRepo：
public interface PersonRepo extends JpaRepository<Person, Long> {
@Override
<S extends Person> S save(S arg0);
@Override
long count();
}
这里是myUI类：
@SpringUI
@Theme("valo")
public class MyUI extends UI {
private static final long serialVersionUID = 1L;
private final PersonRepo personRepo;
@Autowired
private MyUI(PersonRepo personRepo) {
this.personRepo = personRepo;
}
@Override
protected void init(VaadinRequest request) {
VerticalLayout layout = new VerticalLayout();
layout.setDefaultComponentAlignment(Alignment.MIDDLE_CENTER);
Person person = new Person();
person.setName("Person");
person.setEmail("Email");
person.setColleague(false);
person.setBirthDay(new Date());
personRepo.save(person);
Label helloWorld = new Label();
helloWorld.setValue("Persons: " + personRepo.count());
helloWorld.setStyleName(ValoTheme.LABEL_H1);
helloWorld.setSizeUndefined();
layout.addComponent(helloWorld);
setContent(layout);
}
}
这里只I @ Autowire PersonRepo，创建新人并保存在分贝中，比标签我显示的人数。但是personRepo为null，@Autowire不起作用。我不知道我的错误在哪里...
