Spring mvc Integration Spring boot et Spring webmvc错误：此依赖项没有autowire候选项

我正在使用SpringBoot实现一个SOAP Web服务，它与SpringWebMVC和JDBCTemplate混合使用。我在DAO上使用@Autowired时遇到问题

联系人DAO

public interface ContactDAO {

public void saveOrUpdate(Contact contact);

public void delete(int contactId);

public Contact get(int contactId);

public List<Contact> list();

}

只需从您的

ContactDAOImpl

类中删除

@Controller（“contactDAO”）

，并将

@Repository

更改为

@Repository（“contactDAO”）
，实际上您似乎有3个ContactDAOImpl
@Controller、@Repository
声明，只需使用其中一个，并启用
或使用带有
@Configuration
注释类的java config
@ComponentScan（“net.codejava.spring”）
，以便spring可以拾取它们
我通过将ContactEndpoint移动到与我的DAO相同的包名来解决问题，因为一开始我的端点是com.spring.countries，而DAO是net.codejava.spring，所以spring找不到绑定。将ContactEndpoint移动到net.codejava.spring解决了这个问题。谢谢你的帮助
