Spring启动应用程序无法启动嵌入式tomcat

标签： java maven spring-boot embedded-tomcat-8

是Spring启动应用程序的新手。我有一个创建公共crud存储库的任务，应该由rest控制器处理。我刚开始用一些例子。但是我的应用程序没有启动嵌入式tomcat。我的其他控制器URI也没有映射。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。

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

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

import java.util.UUID;

public interface CRUDEngineService {

void save(Object entity);

void delete(UUID id);
}

服务实现类是

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);
}
}

crud存储库实现

import java.util.UUID;
import org.springframework.data.repository.CrudRepository;

public interface CRUDEngineRespository extends CrudRepository<Object, UUID> 
{

}

Child pom.xml是

答案 0 :(得分：1)

从pom.xml中删除<scope>provided</scope>并尝试重新运行。如果您希望将战争部署到任何其他独立的tomcat，请使用提供的。
