Question

我有一个带有spring-boot的项目，我使用了spring 2.0.5.RELEASE版本。而且，当我简化getter和setter以及有无字段的controctor的工作时，我想使用Lombok，这是我pom.xml的文件

在“大纲”视图中，当我选择班级的窗口时，我看不到getter和setter方法，这是我的Etudiant课程的源代码：

package hr.access.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.Temporal;
import javax.persistence.TemporalType;

import lombok.AllArgsConstructor;
import lombok.Data;
import lombok.NoArgsConstructor;

@Entity
@Data
@AllArgsConstructor
@NoArgsConstructor
public class Etudiant {

@Id
@GeneratedValue(strategy = GenerationType.IDENTITY)
private Long id;
@Column(length = 80)
private String nom;
@Column(length = 80)
private String prenom;
@Temporal(TemporalType.DATE)
private Date dateNaissance;

}

我在此代码中有什么错误，您会写什么并添加到我的代码中，因为我的班级正确吗？

Answer 1

如果您的问题是您看不到getter和setter没问题，因为lombok在Etudiant.class文件的编译时提供了它但是您必须在IDE中使用lombok插件

设置指南https://projectlombok.org/setup/overview

Answer 2

这应该可行，尝试一下；

该项目具有lombok依赖性。首先查看您的.m2 仓库，如果没有，找到龙目岛罐子！
双击在jar上，指定IDE的路径，例如C:\Users\ide\install\package\yourIDE.exe
重新启动IDE并更新Maven项目。

Answer 3

LomBok在m2文件夹（mvn缓存文件夹）中有一个jar 例如：C：\ Users \ Mypc \ .m2 \ repository \ org \ projectlombok \ lombok \ 1.18.12（基于必须执行的mvn软件包）将搜索ide

然后您需要重新启动ide，然后在类中进行搜索，您会看到getter和setters

龙目岛不适用于spring-boot-maven
