MapStruct 没有合格的 bean
No qualifying bean with MapStruct
我在 Tomcat 9 中使用 MapStruct、Lombock 和 Spring 时在应用程序部署中遇到以下错误:
No qualifying bean of type 'somepackage.ControllerBusinessMapper'
available: expected at least 1 bean which qualifies as autowire
candidate
这是我的 pom.xml:
<dependency>
<groupId>org.projectlombok</groupId>
<artifactId>lombok</artifactId>
<version>[1.18.12,)</version>
<scope>provided</scope>
</dependency>

这是映射器:
@Mapper(componentModel = "spring")
public interface ControllerBusinessMapper {
//Some methods
}
并且在 class 注入的地方:
@Autowired
private ControllerBusinessMapper businessMapper;
我的 spring 配置 class 将包扫描设置在包层次结构的根目录中。映射器的实现也在 target/generated-sources:
下生成
@Generated(
value = "org.mapstruct.ap.MappingProcessor",
date = "2020-08-23T03:56:23+0200",
comments = "version: 1.3.1.Final, compiler: javac, environment: Java 11.0.7 (Oracle Corporation)"
)
@Component
public class ControllerBusinessMapperImpl implements ControllerBusinessMapper {
//Some methods
}
我的错误提示 Spring 无法找到实现 class,我错过了什么?我尝试将 generated-sources 文件夹添加到构建路径并将其包含在包扫描中,但没有成功。
需要在 Eclipse 中进行额外配置才能使用 MapStruct:
- 安装 m2e-apt 插件
- 在每个 Maven 模块中转到 Maven > Annotation Processing
- 选中启用项目特定设置
- Select自动配置JDT APT模式
