使用多模块结构
Sort-Api 是充当控制器的模块，它调用服务和服务内部调用模型。
服务代码
import com.mayank.repository1.PersonRepository;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
/**
* @author Mayank
*/
@Service
public class PersonalizedSortServiceImpl implements PersonalizedSortService {
@Autowired
PersonRepository personRepository;
@Override
public String fetchFromCassandra() {
personRepository.findAll();
// while(books.)
// UUID uuid = new UUID(123);
// return personRepository.findByUuid(uuid);
return "maynk";
}
}
Spring Boot 应用程序包含
//@Configuration
//@EnableAutoConfiguration
@ComponentScan(basePackages ={"com.mayank"})
@EntityScan(basePackages ={"com.mayank.resources"})
//@Enable({"com.mayank"})
public class Application extends SpringBootServletInitializer {
private static final Logger log = LoggerFactory.getLogger(Application.class);
public static void main(String[] args) {
SpringApplication app = new SpringApplication(Application.class);
app.run(args);
}
编辑：-我移动了所有不同的模块，然后检查，它工作正常。但是移动到不同的模块会导致这个问题。似乎Spring无法定位PersonRepository
还编辑了我的 Application.java
解决方案
您尚未在主类中添加组件扫描，因此 spring 无法找到 Spring 托管组件。在 Application 类中添加以下内容将修复错误：
@ComponentScan(basePackages = "com.mayank")
