[英]Error creating bean with name 'entityManagerFactory' in my project with spring boot
[英]Spring Boot project error creating bean
我有以下代碼:
package com.frameworkonly.webapp;
import java.util.ArrayList;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.EnableAutoConfiguration;
import org.springframework.boot.autoconfigure.web.ErrorMvcAutoConfiguration;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;
import com.frameworkonly.webapp.domain.Employee;
import com.frameworkonly.webapp.service.EmployeeServiceInterface;
@EnableAutoConfiguration(exclude = {ErrorMvcAutoConfiguration.class})
@ComponentScan("com.frameworkonly.webapp")
public class SpringBootDemoApplication {
@Autowired
EmployeeServiceInterface employeeServiceInterface;
public static void main(String[] args) {
SpringApplication.run(SpringBootDemoApplication.class, args);
}
}
我剛開始使用Spring Boot
。 它給了我以下信息,我不知道這意味着什么:
Error creating bean with name 'springBootDemoApplication': Injection of
autowired dependencies failed; nested exception is
org.springframework.beans.factory.BeanCreationException: Could not autowire
field: com.exemple.service.PatientServiceInterface
com.example.SpringBootDemoApplication.patientServiceInterface; nested
exception is org.springframework.beans.factory.NoSuchBeanDefinitionException:
No qualifying bean of type [com.exemple.service.PatientServiceInterface]
found for dependency: expected at least 1 bean which qualifies as autowire
candidate for this dependency.
添加com.exemple.service
到掃描包假設列表PatientServiceInterface
都被注解@Service
@ComponentScan({"com.frameworkonly.webapp","com.exemple.service"})
