Maven lombok未满足的费用例外

项目：spring boot、maven、使用Lombok的intellij idea。 生成项目时，会生成错误UnsatifiedPendencyException。 没有使用龙目，一切都很好

源代码可以在这里找到。 log.txt-完整启动日志

Error creating bean with name 'testController': Unsatisfied dependency expressed through field 'repository'.

请告诉我，在哪里查找错误？

我刚刚运行了您的代码并得到了，关键部分是由以下原因引起的：

：java.lang.IllegalArgumentException:非托管类型：class com.example.demo.City

Spring Boot无法持久化

City

类

解决方案是向其添加

@Entity

注释：

import lombok.Data;

import javax.persistence.Entity;
import javax.persistence.Id;

@Data
@Entity
public class City{
    @Id
    private int id;
    private String name;
    private String region;
}

之后，代码成功编译，嵌入式tomcat服务器在IntelliJ中启动良好：

2017-08-19 12:41:05.703信息10664-[main]com.example.demo.DemoApplication:在3.651秒内启动了DemoApplication（JVM运行4.312）

---

在成功编译过程中，没有从项目中剥离lombok。无论如何，这个问题仍然存在。因此，我不认为龙目岛是根本原因。

错误消息只说明创建城市存储库时出错。实际的根本原因可能可以在日志中找到。添加注释@Entity治愈了患者。
