我使用Sping Boot 初始化我的项目,实际上,我通过Sping Boot 包含了Lombok依赖项,并如下配置了Lombok插件:
我使用的IDE是Eclipse

字符串
然而,当我在名为department.java的实体类中使用它时,Lombok似乎没有按预期工作。即使使用@Data,@NoArgsConstructor,@AllArgsConstructor和@Builder注解该类后,问题仍然存在。

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;
}


在另一个配置Java类中,我也无法使用department类的getter和setter方法。

package com.springbootExample.SpringBoot_Example.service;

import java.util.List;
import java.util.Objects;
import java.util.Optional;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;

import com.springbootExample.SpringBoot_Example.entity.department;
import com.springbootExample.SpringBoot_Example.error.departmentExceptionHandling;
import com.springbootExample.SpringBoot_Example.repository.departmentRepository;

@Service
public class departmentServiceImplement implements departmentService{
    
    @Autowired
    private departmentRepository dr;

    @Override
    public department saveDepartment(department dp) {
        return dr.save(dp);
    }

    @Override
    public List<department> fetchDepartment() {
        return dr.findAll();
    }

    @Override
    public department fetchDepartmentById(Long departmentID) throws departmentExceptionHandling {
        Optional<department> dpt = dr.findById(departmentID);
        
        if(!dpt.isPresent()) {
            throw new departmentExceptionHandling("Department was not found");
        }
        return dpt.get();
    }

    @Override
    public void deleteDepartmentById(Long departmentID) {
        dr.deleteById(departmentID);
        
    }

    @Override
    public department updateDepartment(Long departmentID, department dp) {
        department dep = dr.findById(departmentID).get();
        
        if(Objects.nonNull(dp.getDepartmentName()) && !"".equalsIgnoreCase(dp.getDepartmentName())) {
            dep.setDepartmentName(dp.getDepartmentName());
        }
        
        if(Objects.nonNull(dp.getDepartmentCode()) && !"".equalsIgnoreCase(dp.getDepartmentCode())) {
            dep.setDepartmentCode(dp.getDepartmentCode());
        }
        
        if(Objects.nonNull(dp.getDepartmentAdress()) && !"".equalsIgnoreCase(dp.getDepartmentAdress())) {
            dep.setDepartmentAdress(dp.getDepartmentAdress());
        }
        
        return dr.save(dep);
    }

    @Override
    public department fetchDepartmentByName(String departmentName) {
        return departmentRepository.findByDepartmentNameIgnoreCase(departmentName);
    } 

}


错误显示为

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

我尝试了几种解决方案,例如更新IDE,更改Lombok插件和安装Lombok,但没有一个解决了这个问题。
如果有人遇到类似的问题,并知道如何解决它,我将非常感谢您的帮助。
先谢谢你了。

尝试删除目标文件夹并再次运行您的项目。它与我一起工作

尝试在IDE中安装项目lombok..然后只有该依赖项按预期工作。项目lombok下载链接:https://projectlombok.org/download ..下载此lombok然后在选择IDE后打开文件然后单击安装..安装lombok后..关闭IDE然后打开IDE

经过几天的故障排除,我终于找到了我的项目或Eclipse IDE无法使用Lombok的原因。为了帮助那些可能面临类似Lombok问题的人,我在这里分享解决方案作为答案。
所以首先你得

Help --> About Eclipse IDE

if you have install Lombok plugin you will see this line --> Lombok v1.18.30 "Envious Ferret" is installed. https://projectlombok.org/

if don't have or already installed but Lombok not work then you go to Installation Detail --> search on the searching bar find the Lombok then delete it

字符串
然后你把这个URL

https://projectlombok.org/p2

go to --> help (section in eclipse) --> install new software --> you will see the "work with" --> pass the URL "https://projectlombok.org/p2" --> click add --> set name is Lombok --> click add

after that tick to the Lombok checkbox then click next --> finish --> wait for the installment completed --> restart the eclipse

then you can use Lombok already


下面这里是图像的描述,你可以看到通过以下步骤
add Lombok with then URL I use above to install Lombok
click finish to install Lombok
非常感谢大家,希望我的问题和解决方法对大家有帮助

我在Eclipse上工作时也遇到了同样的问题。即使在pom.xml文件中添加jar作为Maven依赖项之后,Eclipse仍然无法识别jar。但是,我能够通过以下步骤解决它:

  • 确保将jar添加到pom.xml文件后,它在.m2文件夹中可用。
  • 打开命令提示符并导航到jar的位置。
  • 运行以下命令:java -jar lombok.jar。将名称替换为准确的版本
  • 将出现Lombok安装窗口。
  • 指定Eclipse安装目录的位置。这将把jar复制到同一个文件夹,并使用必要的条目更新eclipse.ini文件。这一步应该可以解决Lombok jar问题。
  • 要确认安装,请转到Eclipse,单击“Help”,然后选择“About IDE”。滚动到页面末尾,您应该会看到Lombok的安装确认。

这些注解是要在编译前执行的,在Gradle中需要使用annotationProcessor <lombok>来实现。您添加的是默认作用域,可能是runtimecompile(不确定)。
对于Maven,您将不得不使用annotationProcessor的等价物,这是here(在问题本身中)。
