我有几天这个错误，似乎没有运气。尝试谷歌搜索，但仍然无法使其工作。在日志中查看它一直告诉我“注入自动连接的依赖项”有问题，但我无法得到它。希望收到你的来信。
错误日志。

public interface UserRepository extends JpaRepository<User, Integer> {
Page<User> findByUserNameLike(Pageable pageable, String UserName);

答案 0 :(得分：0)
创建JPA配置类，如下所示：
@Configuration
@EnableJpaRepositories(basePackages="com.sesame.repository")
@EntityScan(basePackages="com.sesame.model")
public class JpaConfiguration {
}
