当我尝试在服务器上部署文件时发生错误。我很困惑,因为这段代码有效。

IC类别服务
public interface ICategoryService
{
public Category create(Category category);
public Category delete(int id) throws Exception;
public List<Category> findAll();
public Category update(Category category) throws Exception;
public Category findById(int id);
}
他的实施
public class CategoryService implements ICategoryService
{
@Autowired
private CategoryRepository categoryRepository;
...
控制器
@Controller
@RequestMapping(value = "/rest")
public class StorageController extends BaseController {
@Autowired
@Qualifier("categoryService")
private ICategoryService _categoryService;
...
数据库.xml
<djpa:repositories base-package="ru.menkin.ea.lec4.model" />
<bean id="categoryService" class="ru.menkin.ea.lec4.model.services.CategoryService" />
beans.xml
<context:annotation-config />
<context:component-scan base-package="ru.menkin.ea" />
我的错误在哪里?
这是异常消息中的最后一个原因:
Error creating bean with name 'jpaMappingContext': Invocation of init method failed; nested exception is javax.persistence.PersistenceException
Spring无法调用你的init方法jpaMappingContext
因为发生了持久性异常 - 数据库中出现了问题。
因此,Spring 自动装配实际上是有效的,但它无法自动装配您的依赖项,因为初始化其中一个 Spring bean 时出现数据库问题。
因此,自该代码上次运行以来,数据库或数据库设置中的某些内容发生了变化。分析完整的堆栈跟踪以找出此问题的根本原因 - 这是数据库问题。
