Question

模型：

简单传感器实体与JPA

package kz.don.sensorTracker.model;

import jakarta.persistence.*;
import lombok.*;

import java.io.Serializable;
import java.time.LocalDateTime;

@Setter
@Getter
@Entity
@Table(name = "SENSORS")
@AllArgsConstructor
@NoArgsConstructor
@Builder
public class Sensor implements Serializable {
    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    @Column(name = "ID")
    private Long id;

    @Column(name = "NAME", nullable = false, unique = true)
    private String name;

    private LocalDateTime initDate;

    @PrePersist
    public void prePersist(){
        initDate = LocalDateTime.now();
    }

}

pom.xml：

我试图专门提供较新版本的Lombok来解决这个问题，但没有任何改变。

/Users/coldkey/Downloads/sensorTracker/src/main/java/kz/don/sensorTracker/controller/SensorController.java:23:16java: cannot find symbolsymbol: method setName(java.lang.String)location: variable sensor1 of type kz.don.sensorTracker.model.Sensor 构建失败 - 那是整个堆栈跟踪

手动创造了产生的getters和setter，它可以完美地工作，但是想法本身建议使用Lombok。 每次我尝试使用Lombok生成的方法时，都会发生错误，但是构造函数与All-Args和No-Args的方法都可以。

这可能是Intellij中Lombok插件的问题，您可以尝试以下步骤-

确保安装Lombok插件

确保您拥有“启用注释处理”选项检查（构建，执行，部署 - >编译器 - >注释处理器）

Answer 1

1. 渗透缓存和重新启动
如果错误仍然存在，然后尝试从命令行构建和运行。有时，Intellij构建会引起由于Lombok问题而引起的编译错误，但是由于代码本身具有正确的Lombok依赖性和配置，因此从命令行中运行良好。

，例如，为Maven Build运行

mvn clean install或从终端运行Spring Boot应用程序。
