Java @映射程序未正确生成实现类

我正在用Mappstruct和Lombok在spring boot中工作。当我使用Mapper anotation自动实现Mapper类时，anotation不会为我的类生成正确的Mapper实现

这是POM.xml

第二个：

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

@Data
@Builder
@AllArgsConstructor
@NoArgsConstructor
@SuppressWarnings("unused")
public class UserRequest {

    private Integer id;

    private String usrLogin;

    private String pass;

    private String name;

    private String surname;

    private Boolean enabled;

}

我的地图绘制者界面：

import com.domotichouse.app.SpringDomoticHouse.application.dto.User;
import com.domotichouse.app.SpringDomoticHouse.rest.dto.UserRequest;
import org.mapstruct.Mapper;
import org.mapstruct.factory.Mappers;


@Mapper
public interface UserRestMapper {
    
    UserRestMapper MAPPER = Mappers.getMapper(UserRestMapper.class);
    
    User toAplication(UserRequest request);
    
}

以下是Anotion如何实现接口：

import com.domotichouse.app.SpringDomoticHouse.application.dto.User;
import com.domotichouse.app.SpringDomoticHouse.rest.dto.UserRequest;

public class UserRestMapperImpl implements UserRestMapper {
    public UserRestMapperImpl() {
    }

    public User toAplication(UserRequest request) {
        if (request == null) {
            return null;
        } else {
            User user = new User();
            return user;
        }
    }
}

正如你所见，地图绘制者不绘制任何东西。

PD：我安装了lombok插件，@Data和@Builder Anotation按预期工作

我们的工作方式如下：

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-compiler-plugin</artifactId>
    <version>${maven-compiler-plugin.version}</version>
    <configuration>
        <source>11</source>
        <target>11</target>
        <annotationProcessorPaths>
            <path>
                <groupId>org.mapstruct</groupId>
                <artifactId>mapstruct-processor</artifactId>
                <version>${mapstruct.version}</version>
            </path>
            <path>
                <groupId>org.projectlombok</groupId>
                <artifactId>lombok</artifactId>
                <version>${lombok.version}</version>
            </path>
        </annotationProcessorPaths>
        <compilerArgs>
            <compilerArg>
                -Amapstruct.defaultComponentModel=spring
            </compilerArg>
        </compilerArgs>
    </configuration>
</plugin>

<scope>provided</scope>

org.apache.maven.plugins
maven编译器插件
${maven编译器plugin.version}

org.mapstruct

${mapstruct.version}
org.projectlombok
龙目
${lombok.version}
-Amapstruct.defaultComponentModel=弹簧

请注意

部分中的差异。

您的问题似乎与此问题重复：

而不是

<annotationProcessorPath>
    <groupId>org.projectlombok</groupId>
    <artifactId>lombok</artifactId>
    <version>${lombok.version}</version>
</annotationProcessorPath>

org.projectlombok
龙目
${lombok.version}

你必须使用

<path>
    <groupId>org.projectlombok</groupId>
    <artifactId>lombok</artifactId>
    <version>${lombok.version}</version>
</path>

org.projectlombok
龙目
${lombok.version}

应提供Maven依赖项“mapstruct processor”，如下所示：

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-compiler-plugin</artifactId>
    <version>${maven-compiler-plugin.version}</version>
    <configuration>
        <source>11</source>
        <target>11</target>
        <annotationProcessorPaths>
            <path>
                <groupId>org.mapstruct</groupId>
                <artifactId>mapstruct-processor</artifactId>
                <version>${mapstruct.version}</version>
            </path>
            <path>
                <groupId>org.projectlombok</groupId>
                <artifactId>lombok</artifactId>
                <version>${lombok.version}</version>
            </path>
        </annotationProcessorPaths>
        <compilerArgs>
            <compilerArg>
                -Amapstruct.defaultComponentModel=spring
            </compilerArg>
        </compilerArgs>
    </configuration>
</plugin>

<scope>provided</scope>

已提供

在此之后，您必须运行Maven build with package goal（mvn package），然后生成的类UserRestMapperImpl应符合您的需要。

                    </compilerArgs>

对我来说似乎不错，运行

mvn clean generate sources compile

如果您在将字段添加到对象之前创建了映射器，那么您的实现可能不正确updated@DavidFlorez我这样做了好几次，但对我不起作用…尝试删除可选项并将lombok作用域设置为提供的。也不起作用。。。我进行了mvn清理和安装，生成的类与berfore相同……我进行了清理安装，但没有任何效果。我运行了应用程序，并且正确生成了类。我停止了应用程序，再次清除了所有内容。我再次运行它，但类再次不正确…还添加了1.8 1.4.1.Final
