实体类代码（department.java） #

package com.springbootExample.SpringBoot_Example.entity;

import jakarta.persistence.Entity;
import jakarta.persistence.GeneratedValue;
import jakarta.persistence.GenerationType;
import jakarta.persistence.Id;
import jakarta.validation.constraints.NotBlank;
import lombok.AllArgsConstructor;
import lombok.Builder;
import lombok.Data;
import lombok.NoArgsConstructor;

@Entity
@Data
@NoArgsConstructor
@AllArgsConstructor
@Builder
public class department {
    
    @Id
    @GeneratedValue(strategy = GenerationType.AUTO)
    private Long departmentID;
    
    @NotBlank(message = "Please add department name")
//  @Length(max = 20, min = 10)
//  @Size
//  @Email
//  @Positive
//  @Negative
//  @PositiveOrZero
//  @Future
//  @Past
//  @FutureOrPresent
    private String departmentName;
    private String departmentAdress;
    private String departmentCode;
}

错误现象 #

在Service实现类中调用实体类的getter方法时，IDE提示以下错误：

The method getDepartmentName() is undefined for the type department
The method getDepartmentCode() is undefined for the type department
The method getDepartmentAdress() is undefined for the type department

已尝试的方案 #

• 更新Eclipse IDE
• 更换Lombok插件版本
• 重新安装Lombok

解决思路 #

• 检查Eclipse注解处理器配置：
  打开Eclipse偏好设置（Window > Preferences），依次进入Java > Compiler > Annotation Processing，确保Enable annotation processing和Enable processing in editor均已勾选；再进入Java > Compiler > Annotation Processing > Factory Path，点击Add External JARs，找到本地Maven仓库中Lombok的jar包（路径示例：~/.m2/repository/org/projectlombok/lombok/[对应版本]/lombok.jar），添加完成后重启Eclipse。

• 验证Lombok插件状态：
  打开Help > About Eclipse IDE，点击Installation Details，在已安装软件列表中搜索Lombok，确认插件已正常安装；若未找到，重新下载对应Eclipse版本的Lombok插件安装包，安装后重启IDE。

• 清理并重构项目：
  执行Maven命令 mvn clean install 清理项目，之后在Eclipse中右键项目选择Maven > Update Project，勾选Force Update of Snapshots/Releases，更新完成后重新编译项目。

• 修正类名命名规范：
  实体类名department不符合Java大驼峰命名规范，改为Department后，Lombok生成的getter方法会自动匹配为getDepartmentName()，避免因命名问题导致的识别异常（虽然Lombok支持小写类名，但规范命名能减少潜在问题）。

• 确认Lombok依赖完整性：
  检查本地Maven仓库中是否存在对应版本的Lombok jar包，若缺失则执行mvn dependency:resolve命令拉取依赖；POM中Lombok的<optional>true</optional>配置是合理的，无需修改。
