我是Spring Boot的初学者 .
UserController.java
@Controller
@ComponentScan("com.foo.dto")
public class UserController {
@Autowired
UserRepository userRepository;
@RequestMapping("/test")
public void test() {
System.out.println("PLEASE RUN");
}
UserRepository extends CrudRepository
@Repository
public interface UserRepository extends CrudRepository<User, Long> {
List<User> findByLastName(String lastName);
List<User> findByAccNameAndPassword(String accName, String password);
}
User .java
@Entity
public class User {
@Id
@GeneratedValue(strategy = GenerationType.AUTO)
private long id;
@NotNull
private String firstName;
@NotNull
private String lastName;
@NotNull
private Date dob;
@NotNull
private String phone;
@NotNull
private String email;
@NotNull
private boolean isEmployer;
@NotNull
private String accountName;
@NotNull
private String password;
protected User() {
}
public User(String firstName, String lastName, Date dob, String email, String phone, String accName,
String password) {
this.firstName = firstName;
this.lastName = lastName;
this.dob = dob;
this.email = email;
this.phone = phone;
this.accountName = accName;
this.password = password;
this.isEmployer = false;
}
当我尝试 RUN 应用程序时抛出异常 .
Exception thrown:
org.springframework.beans.factory.NoSuchBeanDefinitionException：没有为依赖项找到类型为[com.foo.dto.UserRepository]的限定bean：期望至少有一个bean符合此依赖关系的autowire候选资格 . 依赖注释：{@ org.springframework.beans.factory.annotation.Autowired（required = true）

我认为您需要在配置中启用它
在@Configuration文件中 .
