Java Spring启动测试未加载带有@Component注释的类

在我的SpringBoot应用程序中，我正在使用@SpringBootTest编写集成测试。我正在使用一个配置类进行配置，并在其上使用了@ComponentScan，但它没有加载组件，测试失败

ApplicationConfig.java

@Configuration
@ComponentScan(basePackages = { "com.example.inventory" })
public class ApplicationConfig {

    @Bean
    public MapperFactory mapperFactory() {
        return new DefaultMapperFactory.Builder().build();
    }
}

@SpringBootTest(classes = ApplicationConfig.class)
@RunWith(SpringRunner.class)
@AutoConfigureMockMvc
public class ProductSupplierIntegrationTests {
    // tests
}

这里DefaultMapperFactory是Orika Mapper的一部分，我使用它将模型转换为DTO，反之亦然

ProductSupplierIntegrationTests.java

@Configuration
@ComponentScan(basePackages = { "com.example.inventory" })
public class ApplicationConfig {

    @Bean
    public MapperFactory mapperFactory() {
        return new DefaultMapperFactory.Builder().build();
    }
}

@SpringBootTest(classes = ApplicationConfig.class)
@RunWith(SpringRunner.class)
@AutoConfigureMockMvc
public class ProductSupplierIntegrationTests {
    // tests
}

产品供应商模型

@Entity
public class ProductSupplier {

    @Id
    @GeneratedValue
    private Long id;

    private Long supplierId;

    @ManyToOne
    private Supplier supplier;

    private Double buyPrice;

    private boolean defaultSupplier;

    // getters and setters
}

@Entity
public class Supplier {

    @Id
    @GeneratedValue
    private Long id;

    private String firstName;

    private String lastName;

    private String email;

    // getters and setters
}

供应商型号

@Entity
public class ProductSupplier {

    @Id
    @GeneratedValue
    private Long id;

    private Long supplierId;

    @ManyToOne
    private Supplier supplier;

    private Double buyPrice;

    private boolean defaultSupplier;

    // getters and setters
}

@Entity
public class Supplier {

    @Id
    @GeneratedValue
    private Long id;

    private String firstName;

    private String lastName;

    private String email;

    // getters and setters
}

产品供应商到

public class ProductSupplierDTO {

    private Long supplierId;

    private String firstName;

    private String lastName;

    private String email;

    private Double buyPrice;

    private Boolean defaultSupplier;

    // getters and setters
}

Orika映射器配置

package com.example.inventory.mapper;

@Component
public class ProductSupplierMapper implements OrikaMapperFactoryConfigurer {

    @Override
    public void configure(MapperFactory orikaMapperFactory) {
        orikaMapperFactory.classMap(ProductSupplier.class, ProductSupplierDTO.class).exclude("id")
                .field("supplier.firstName", "firstName").field("supplier.lastName", "lastName")
                .field("supplier.email", "email").byDefault().register();
    }

}

当我运行应用程序时，spring加载映射器并在上下文中注册它，并按照我的指定在pojo之间进行转换，但当我运行集成测试时，映射器未加载，pojo使用默认orika配置进行转换，字段firstName、lastName和email未映射到DTO中

有人能告诉我在测试配置中缺少了什么吗？

您是否尝试过在现场不使用dot。我的意思是没有必要使用suplier。只需使用字段名。点用于在一个类中映射两个类的属性。我不认为orika是这里的问题，因为当我运行主应用程序时，它可以完美地工作。您的

@SpringBootTest

应该引用

@SpringBootApplication

注释类。@ComponentScan注释正确吗？您的类真的在“com.example.inventory”中吗？如果我使用

@SpringBootApplication

，那么它会为每个测试加载应用程序上下文。
