我想下面的代碼運行異常線程 「main」 org.springframework.beans.factory.BeanCreationException：錯誤創建豆
import org.springframework.context.ApplicationContext;
import org.springframework.context.annotation.AnnotationConfigApplicationContext;
import org.uprs.config.AppConfig;
import org.uprs.model.POC;
import org.uprs.repository.POCRepository;
public class test {
public static void main(String[] args) {
ApplicationContext context = new AnnotationConfigApplicationContext(AppConfig.class);
POC person = new POC();
person.setID(2l);
person.setName("Rohit");
person.setOwner("Mishra");
person.setEngagement("Pune");
context.getBean(POCRepository.class).save(person);
}
}
我的配置類：

我的倉庫類：POCRepository類
package org.uprs.repository;

@RestController
@RequestMapping("/poc")
public class POCService {
@Autowired
POCRepository pocRepository;
@RequestMapping(value = "/all", method = RequestMethod.GET)
public List<POC> getPOCDetails(){
return (List<POC>) pocRepository.findAll();
}
}
我運行的主類並得到以下錯誤。

請幫我
您正試圖在非web環境中配置web相關功能... –
在主類中應該做些什麼，以便我可以模擬測試插入數據的代碼 –
