我对一次提交进行了几处更改,但突然间我的Spring程序似乎无法初始化实体并将它们链接到存储库。当我启动Spring时,我的日志如下:

主要,我担心的错误日志是这样的:
2022-07-10 16:39:18.240 INFO 18040 --- [ restartedMain] .RepositoryConfigurationExtensionSupport : Spring Data JDBC - Could not safely identify store assignment for repository candidate interface com.vendify.Repositories.Auth0TokensCacheRepository. If you want this repository to be a JDBC repository, consider annotating your entities with one of these annotations: org.springframework.data.relational.core.mapping.Table.
这是我编写实体类的示例(它们全部都是这样编写的,并且我已经有一段时间没有修改它们了。在此之前,它们似乎是可以工作的...)
package com.vendify.Entities;
import java.util.Date;
import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.GenerationType;
import javax.persistence.Id;
import javax.persistence.Table;
import org.springframework.lang.NonNull;
import lombok.Getter;
import lombok.Setter;
@Entity
@Table(name = "Logging")
@Getter
@Setter
public class LoggingEntity {
//specific code removed for security
}
使用类似于以下的存储库类:
package com.vendify.Repositories;
import java.util.Date;
import java.util.List;
import org.springframework.data.repository.CrudRepository;
import org.springframework.data.rest.core.annotation.RepositoryRestResource;
import com.vendify.Entities.Auth0TokensCacheEntity;
@RepositoryRestResource(exported = false)
public interface Auth0TokensCacheRepository extends CrudRepository<Auth0TokensCacheEntity, String> {
}
作为证明,我的MySQL数据库结构表看起来有点像这样: Spring似乎能够连接到数据库,而且一直以来都没有问题……我添加了一些包,它会影响其他一些东西,似乎就是在那时出现了问题,因此为了提供一些背景信息,下面是我的程序大致的布局: 非常感谢您的帮助!祝愿你和你的项目顺利!
更新:我尝试了Dhana建议的用JPARepository替换CRUDRepository等注释的解决方案(谢谢:)),Spring找到了所有这些repositories。但是,现在我的所有API端点都没有响应,甚至连开发者工具的端点也没反应了。当我添加@ComponentScan(basePackageClasses = {my controller classes})时,它会报一个应用程序错误,说Spring找不到服务类。请注意,截至目前,当我调用一个端点时,函数仍然可以正常运行(它可以正确地system.out.print输出结果),但因某种原因,无法将其正确返回到Web服务器以显示。
Description:
Field auth0TokensCacheService in com.vendify.Controllers.{ControllerClass} required a bean of type 'com.vendify.Services.{ControllerClass}' that could not be found.
The injection point has the following annotations:
- @org.springframework.beans.factory.annotation.Autowired(required=true)
Action:
Consider defining a bean of type 'com.vendify.Services.{ControllerClass}' in your configuration.
我的Service类看起来像这样:
@Service
public class HiddenService {
@Autowired
HiddenRepository hiddenRepository;
//methods in here
}
我的Controller长这样:
@RestController
public class HiddenController {
@GetMapping("/endpointURL")
//method here
}
感谢!
