Spring Boot应用程序未启动嵌入式Tomcat [英] Spring boot application not starting embedded tomcat
本文介绍了Spring Boot应用程序未启动嵌入式Tomcat的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
是Spring Boot应用程序的新手.我有一个任务来创建应该由rest控制器处理的通用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.另外我的休息控制器URI没有映射.这是Maven模块项目，所有依赖项都在父Maven中配置.如何解决这个问题.
Am newbie to Spring boot application. I have a task to create common crud repository which should be processed by rest controller. I just started with some example. But my application is not started the embedded tomcat. Also my rest controller URI are not mapping. This is maven module project and all the dependency are configured in parent maven. How to resolve this.
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);
}
}
服务界面是
import java.util.UUID;
public interface CRUDEngineService {
void save(Object entity);
void delete(UUID id);
}
服务实现类为
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);
}
}
crud存储库的实现是
And the crud repository implementation is
import java.util.UUID;
import org.springframework.data.repository.CrudRepository;
public interface CRUDEngineRespository extends CrudRepository<Object, UUID>
{
}

推荐答案
从pom.xml中删除<scope>provided</scope>，然后尝试重新运行.如果您希望将战争部署到任何其他独立的Tomcat，请使用已提供的.
Remove <scope>provided</scope> from pom.xml and try re-running. Use provided if you wish to deploy the war to any other standalone tomcat.
