我正在处理一个项目，但是我没有找到属性类型错误。 请检查我的代码并尝试了解问题所在。

我的pom.xml和application.properties文件工作正常，问题出在哪里？感谢...

1 个答案:

答案 0 :(得分：0)

我认为问题出在你的回购中：

public interface MesafeRepository extends JpaRepository<Mesafe, Long>{

    public List<Mesafe> findByName(String name);
}

根据方法findByName，您的实体应具有属性name，但Mesafe实体中没有此类属性

您可以从repo中删除此方法，或将相应的属性添加到实体
