Spring数据JDBC -无法安全地识别存储库候选库的存储分配。
Spring数据JDBC -无法安全地识别存储库候选库的存储分配。
提问于 2022-07-10 23:51:54
我对提交做了一些更改，突然之间，我的spring程序似乎无法初始化实体并将它们链接到存储库。当我开始春天，我得到这个作为我的日志：

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.这是我如何编码实体类的一个例子(所有这些类都是这样的，我已经很久没有接触它们了)。他们似乎以前曾工作过。)
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
}使用类似的存储库类，如下所示：
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，而且在很长一段时间内，它没有任何问题.我添加了几个包，它还处理了一些其他的东西，似乎是在它崩溃的时候，所以对于某些上下文，下面是我的程序的一般布局：
我们将非常感谢您的帮助！非常感谢你，祝你的项目伙伴们好运！
更新:我尝试了用CRUDRepository代替JPARepository的解决方案，以及Dhana建议的其他注释(谢谢：)，spring找到了所有这些存储库。但是，我的所有API端点现在都没有响应，甚至执行器端点也是如此。另外，当添加@ComponentScan(basePackageClasses = {my控制器类})时，我得到一个应用程序错误，spring找不到服务类。请注意，到目前为止，当我调用端点时，函数仍然正常运行(它可以正确地system.out.print结果，但由于某些原因，不能将其正确地返回到要显示的when服务器。
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.我的服务类如下所示：
@Service
public class HiddenService {
@Autowired
HiddenRepository hiddenRepository;
//methods in here
}我的主计长是这样的：
@RestController
public class HiddenController {
@GetMapping("/endpointURL")
//method here
} 谢谢!

让我解释一下，根据我的理解，当一个项目中有多个Spring数据模块与Spring同时存在时，如果您试图通过从公共模块扩展接口来为特定实体创建一个接口，而该实体没有使用特定的持久性注释进行注释。这肯定不起作用，因为spring基本上不知道实体与哪个数据存储相关联。因此，尝试将其扩展到特定的存储库，例如，如果您正在使用MySQL，请选择JpaRepository而不是CrudRepository，无论如何，在层次结构的某个点，它们将相互链接，但仍然建议将实体与特定的存储库相关联。
最后，确保将这些添加到各自的文件中：
- @Repository在您的自定义回购
中
将此添加到application.properties中的
spring.data.jdbc.repositories.enabled=false
希望它对你有帮助！)
