使用 Spring 创建 MapStruct bean 时出错

Question

在这里尝试用 MapStruct 做一些测试。我有以下课程：

测试类

RunWith(SpringJUnit4ClassRunner.class)
@SpringBootTest
public class MapperTests {

@Autowired
private UsuarioMapper usuarioMapper; //Can't autowire(No typo found)

@Test
public void dadoUsuarioSalvarDTO_quandoMapeioParaUsuario_entaoRetornaUsuario(){

    //Dado
    UsuarioSalvarDTO usuarioSalvarDTO = new UsuarioSalvarDTO();
    usuarioSalvarDTO.setEmail("test@test.com");
    usuarioSalvarDTO.setSenha("123456789");
    usuarioSalvarDTO.setStatus(TipoStatus.ATIVO);

    Usuario usuario = usuarioMapper.toEntity(usuarioSalvarDTO);

    Assert.assertEquals(usuario.getEmail(), "test@test.com");
    Assert.assertEquals(usuario.getSenha(), "123456789");
    Assert.assertEquals(usuario.getStatus(), TipoStatus.ATIVO);


}
}

映射器

@Mapper(componentModel = "spring", unmappedTargetPolicy = ReportingPolicy.WARN)
public interface UsuarioMapper {

@Mappings({
        @Mapping(target = "id", ignore = true),
        @Mapping(target = "createdAt", ignore = true),
        @Mapping(target = "updatetAt", ignore = true),
        @Mapping(source="usuarioSalvarDTO.email", target = "email")
})
Usuario toEntity(UsuarioSalvarDTO usuarioSalvarDTO);

}

在此处考虑模型

生成的 UsuarioMapperImpl：

@Generated(
value = "org.mapstruct.ap.MappingProcessor",
date = "2018-11-24T00:40:25-0200",
comments = "version: 1.2.0.Final, compiler: javac, environment: Java 1.8.0_181 (Oracle Corporation)"
)
@Component
public class UsuarioMapperImpl implements UsuarioMapper {

@Override
public Usuario toEntity(UsuarioSalvarDTO usuarioSalvarDTO) {
    if ( usuarioSalvarDTO == null ) {
        return null;
    }

    Usuario usuario = new Usuario();

    usuario.setEmail( usuarioSalvarDTO.getEmail() );
    usuario.setSenha( usuarioSalvarDTO.getSenha() );
    usuario.setStatus( usuarioSalvarDTO.getStatus() );

    return usuario;
    }
}

当我尝试运行测试时，他给出了以下错误：

org.springframework.beans.factory.UnsatisfiedDependencyException: Error         creating bean with name 'br.com.financeiroAdam.demo.MapperTests': Unsatisfied dependency expressed through field 'usuarioMapper'; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type 'br.com.financeiroAdam.demo.mapper.UsuarioMapper' available: expected at least 1 bean which qualifies as autowire candidate.

MapperTest 中的@Autowire 不起作用。它声称：'无法自动接线。没有找到 'UsuarioMapper' 类型的 bean。'

已经试过了：

• gradle build（无错误）
• gradle build -x test（无错误）
• 使缓存无效/重新启动
• 重新导入项目

使用：

• IntelliJ
• 分级
• 春天
• 龙目岛

build.gradle

buildscript {
ext {
    springBootVersion = '2.1.0.RELEASE'
}
repositories {
    mavenCentral()
}
dependencies {
    classpath("org.springframework.boot:spring-boot-gradle-plugin:${springBootVersion}")
}
}

plugins {
id 'net.ltgt.apt' version '0.8'
}

apply plugin: 'java'
apply plugin: 'eclipse'
apply plugin: 'org.springframework.boot'
apply plugin: 'io.spring.dependency-management'

group = 'br.com.financeiroAdam'
version = '0.0.1-SNAPSHOT'
sourceCompatibility = 1.8

repositories {
mavenCentral()
}


dependencies {
implementation('org.springframework.boot:spring-boot-starter-data-jpa')
implementation('org.springframework.boot:spring-boot-starter-web')

compileOnly('org.projectlombok:lombok:1.18.2')

compile 'org.mapstruct:mapstruct-jdk8:1.2.0.Final'
testImplementation('org.springframework.boot:spring-boot-starter-test')

apt('org.projectlombok:lombok:1.18.2')
apt('org.mapstruct:mapstruct-processor:1.2.0.Final')

}

什么都试过了。我认为 mapstruct 根本不想工作。 有什么解决办法吗？

Answer 1

//Use @Mock instead of @Autowired

@Mock
private UsuarioMapper usuarioMapper; 

//In test method use the below
    Mockito.doReturn(info).when(usuarioMapper).XYXMethod(ArgumentMatchers.argThat(t24InfoMatcher));

Answer 2

添加包含以下内容的配置文件：

       @ComponentScan("The path to mapstract classes")

       @Configuration
       public class MapstructConfig {   
       }

并添加到 spring.factories 文件中：

       org.springframework.boot.autoconfigure.EnableAutoConfiguration=
       "The path of the config class that created"
