Spring 启动应用程序未启动嵌入式 tomcat
Spring boot application not starting embedded tomcat
我是 Spring 启动应用程序的新手。我有一个任务是创建应该由 rest 控制器处理的公共 crud 存储库。我只是从一些例子开始。但是我的应用程序没有启动嵌入式tomcat。我的其余控制器 URI 也没有映射。这是 maven 模块项目，所有依赖项都在 parent maven 中配置。如何解决这个问题。
这是我的代码
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
@SpringBootApplication
public class CRUDEngineApplication {
public static void main(String[] args) {
SpringApplication.run(CRUDEngineApplication.class, args);
}
}
控制器是
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.RestController;
import com.scm.services.CRUDEngineService;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.http.HttpStatus;
import org.springframework.http.ResponseEntity;
import org.springframework.web.bind.annotation.RequestBody;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
@RestController("/api")
public class CRUDEngineController {
@Autowired
private CRUDEngineService crudEngineService;
public static final Logger logger =
LoggerFactory.getLogger(CRUDEngineController.class);
/* public void setProductService(CRUDEngineService crudEngineService) {
this.crudEngineService = crudEngineService;
}*/
@RequestMapping(value = "/user", method = RequestMethod.POST)
public ResponseEntity<?> createUser(@RequestBody Object entity) {
System.out.println("Check point entered.");
crudEngineService.save(entity);
return new ResponseEntity<String>( HttpStatus.CREATED);
}
}
服务接口为
import java.util.UUID;
public interface CRUDEngineService {
void save(Object entity);
void delete(UUID id);
}
服务实现class是
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
import com.scm.repositories.CRUDEngineRespository;
import java.util.UUID;
@Service
public class CRUDEngineServiceImpl implements CRUDEngineService {
@Autowired
private CRUDEngineRespository productRepository;
@Override
public void save(Object entity) {
productRepository.save(entity);
}
@Override
public void delete(UUID id) {
productRepository.delete(id);
}
}
并且 crud 存储库实现是
import java.util.UUID;
import org.springframework.data.repository.CrudRepository;
public interface CRUDEngineRespository extends CrudRepository<Object, UUID>
{
}
