我对一个commit做了一些修改，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。当我启动spring时，我得到了这样的日志：

主要是，我关心的错误是这样的日志：

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.

这是我如何编写实体类的一个例子（所有的都是这样的，我已经很久没有碰过它们了。它们似乎以前工作过...）

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

}

型
使用类似的repository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：x1c 0d1x
Spring似乎能够连接到数据库，并且在很长一段时间内，它没有任何问题.我添加了一些包，它弄乱了一些其他的东西，看起来就像是它崩溃的时候，所以对于一些上下文，这里是我的程序通常是如何布局的：

帮助将不胜感激！非常感谢你和你的项目开发人员好运！
更新：我尝试了用JPARepository和Dhana建议的其他注解替换CRUDRepository的解决方案（谢谢：）），spring找到了所有这些repository。然而，我所有的API端点现在都没有响应，甚至是actuator端点。另外，当添加@ basePackageClasses = {my controller classes}时，我得到了一个应用程序错误，spring无法找到service classes。请注意，截至目前，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，但由于某种原因，无法正确地将其返回到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.

型
我的服务类看起来像这样：

@Service
public class HiddenService {
    @Autowired
    HiddenRepository hiddenRepository;
//methods in here
}

型
我的控制器看起来像这样：

@RestController
public class HiddenController {

@GetMapping("/endpointURL")
//method here

}

谢谢你，谢谢

让我解释一下，根据我的理解，当你在一个项目中有多个spring-data模块和Spring Data JDBC时，如果你试图通过从公共模块扩展接口来为一个没有用特定持久性注解注解的特定实体创建接口，这肯定是行不通的，因为spring基本上不知道你的实体与哪个数据存储相关联。所以，尝试将其扩展到特定的存储库，例如，如果您使用MySQL，请使用JpaRepository而不是CrudRepository，无论如何，在层次结构的某个点上，它们将在内部相互链接，仍然建议将您的实体与特定的存储库相关联
最后，确保将这些添加到相应的文件中：
1.@Repository内置自定义存储库
1.将此添加到您的application.properties
spring.data.jdbc.repositories.enabled=false
希望对你有帮助！：）

如果你得到了无法识别的包的错误，那么你可以尝试像这样构造你的项目。

我在pom.xml中有这3个库

<dependency>
        <groupId>org.springframework.data</groupId>
        <artifactId>spring-data-jpa</artifactId>
    </dependency>
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-data-jpa</artifactId>
    </dependency>
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-data-jdbc</artifactId>
    </dependency>

我删除了spring-data-jpa和spring-boot-starter-data-jdbc，并修复了它。
