Idea中 lombok 在“测试类中-单元测试”运行失败及解决方法

若行若冲2025-08-24 20:30

现象：

使用了lombok注解
在测试类进行测试时找不到类，导致测试失败

解决如下

1.1 查看lombok插件，如果没有安装

1.2 配置"注释处理器"

1.3 配置pom.xml 添加 maven 插件

xml 复制代码

<dependencies>
... 
    <!-- Lombok 依赖 -->
    <dependency>
        <groupId>org.projectlombok</groupId>
        <artifactId>lombok</artifactId>
        <scope>provided</scope>
        <version>1.18.38</version>
    </dependency>
</dependencies>    

...

<build>
    <plugins>
        <!-- maven插件 -->
        <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-compiler-plugin</artifactId>
            <version>3.8.1</version>
            <configuration>
                <source>1.8</source>
                <target>1.8</target>
                <encoding>UTF-8</encoding>
                <annotationProcessorPaths>
                    <path>
                        <groupId>org.projectlombok</groupId>
                        <artifactId>lombok</artifactId>
                        <version>1.18.38</version>
                    </path>
                    <!-- 如果用了 lombok-adder，也需要加上 -->
                </annotationProcessorPaths>
            </configuration>
        </plugin>
   
        <plugin>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-maven-plugin</artifactId>
            <version>${spring-boot.version}</version>
            <configuration>
                <mainClass>io.rizi.pear.PearAdminCurd2Application</mainClass>
                <skip>true</skip>
            </configuration>
            <executions>
                <execution>
                    <id>repackage</id>
                    <goals>
                        <goal>repackage</goal>
                    </goals>
                </execution>
            </executions>
        </plugin>
    </plugins>
</build>

1.4 查看 mapper 接口类的Mapper引用

1.5 实体类

java 复制代码

package io.rizi.layuibook.entity;

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

@Data
@NoArgsConstructor
@AllArgsConstructor
@ToString

public class Category {

        private Integer categoryId;

        private String categoryName;
}

1.6 测试类

java 复制代码

package io.rizi.layuibook.mapper;

import io.rizi.layuibook.LayuiBookApplicationTests;
import org.junit.jupiter.api.Test;

import javax.annotation.Resource;

import static org.junit.jupiter.api.Assertions.*;

class CategoryBakMapperTest extends LayuiBookApplicationTests {

    @Resource
    private CategoryMapper categoryMapper;

    @Test
    void getCategoryList() {

        categoryMapper.getCategoryList().forEach(System.out::println);
    }
}

再次单元测试，成功！
