“NoSuchBeanDefinitionException:在已经实现的单元测试类中添加新的依赖项注入后没有类型的合格bean”错误

Question

Caused by: org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type 'org.companyname.enterpriseteam.demo.anonymizer.DAnonymizer' available: expected at least 1 bean which qualifies as autowire candidate. Dependency annotations: {}

下面是一个模拟但逻辑上准确的代码表示形式

配置包

…
import org.companyname.enterpriseteam.demo.anonymizer.DAnonymizer;
import org.companyname.entuserfilter.externals.adminusersearch.AdminSearchUserRecordsAnonymizer;
…


@Configuration
public class AdminUserSearchAnonymizationConfiguration {
  @Bean
  public AdminSearchUserRecordsAnonymizer
      adminSearchUserRecordsAnonymizer(final DAnonymizer dAnonymizer) {
    return new adminSearchUserRecordsAnonymizerImpl(dAnonymizer);
  }
}

我在不同的包中创建的新接口

…
Some imports
…

public interface AdminSearchUserRecordsAnonymizer {
  List<StoredUserRecord> anonymizeAdminSearchUserRecordsIfNeeded(
      final List<StoredUserRecord> storedUserRecords,
      final String orgId,
      @Nullable final Long requestUserId);
}

接口的实现

…
Some imports
…


public class AdminSearchUserRecordsAnonymizerImpl
    implements AdminSearchUserRecordsAnonymizer {
  private final DAnonymizer dAnonymizer;

  public AdminSearchUserRecordsAnonymizerImpl(final DAnonymizer dAnonymizer) {
    this.dAnonymizer = dAnonymizer;
  }


  @Override
  public List<StoredUserRecord> anonymizeAdminSearchUserRecordsIfNeeded(
      final List<StoredUserRecord> storedUserRecords,
      final String orgId,
      @Nullable final Long requestUserId) {
    if (!DConstants.COMPANY_ORG_ID.equals(orgId) || requestUserId == null) {
      // System.out.println("NO ANONYMIZATION" + storedUserRecords);
      return storedUserRecords;
    }

    // System.out.println("ANONYMIZATION TO BE DONE ON USER RECORDS LIST" + storedUserRecords);
    return storedUserRecords.stream()
        .map(entry -> anonymizeUserRecordIfNeeded(entry, orgId, requestUserId))
        .collect(Collectors.toList());
  }


  private StoredUserRecord anonymizeUserRecordIfNeeded(
      final StoredUserRecord storedUserRecord, final String orgId, final Long requestUserId) {
        final var anonymizedStoredUserRecord =
        dAnonymizer.getAnonymizedUserInfoForOrg(
            orgId, storedUserRecord.userId().get(), requestUserId);

        return anonymizedStoredUserRecord
        .map(
            anon ->
                new StoredUserRecord(
                    storedUserRecord.userId(),
                    anon.email(),
                    storedUserRecord.externalId(),
                    anon.name(),
        .orElse(storedUserRecord);
  }
}

执行依赖项注入的类的构造函数。

…
Some imports
…

public class AdminViewElasticSearchManager implements AdminViewManager {
  private final someObject1;
  private final someObject2;
  private final someObject3;
  private final someObject4;
  private final AdminSearchUserRecordsAnonymizer
        adminSearchUserRecordsAnonymizer;

public AdminViewElasticSearchManager(
    someClass1 someObject1,
    someClass2 someObject2,
    someClass3 someObject3,
    someClass4 someObject4,
    AdminSearchUserRecordsAnonymizer
        adminSearchUserRecordsAnonymizer
    ) {
  this.elasticSearchReader = elasticSearchReader;
  this.someObject1 = someObject1;
  this.someObject2 = someObject2;
  this.someObject3 = someObject3;
  this.someObject4 = someObject4;
  this.adminSearchUserRecordsAnonymizer =
          adminSearchUserRecordsAnonymizer;

}

我在上面这个类中的某个地方使用我的新实现的方法

@Override
public UserRecordsWithPagination searchWithFilterParams(filterParams, pageRequest, requestUser) {
…
Some code
…

storedUserRecords =
this.adminSearchUserRecordsAnonymizer.anonymizeAdminSearchUserRecordsIfNeeded(
           storedUserRecords, filterParams.orgId, requestUser);
…
More code
…

}

由于依赖注入问题，许多测试都失败了，因为它，我无法正确地进行测试。这个特殊的测试也不像它应该的那样断言，这意味着我的新类没有将正确的列表返回给它的调用者。我想知道它是否与依赖关系没有被正确注入？

…
var filterParams =
    FilterParams.newBuilder()
        .setOrganizationId(UserRecordFixtures.MEMBER_USER_RECORD.organizationId())
        .setSearchNameOrEmails(List.of("johndoe"))
        .build();

var pageRequest =
    PageRequest.newBuilder()
        .setStart(Int64Value.of(0))
        .setLimit(Int64Value.of(1))
        .build();

var result = this.manager.queryByFilterParams(filterParams, pageRequest, null);
System.out.println("THIS IS MY RESULT: " + result);
Assertions.assertEquals(1, result.userRecords().size());
…

Answer 1

在配置类中定义DAnonymizer bean，如下所示

@Configuration
public class DAnonymizerConfig {
  
  @Bean
  public DAnonymizer dAnonymizer() {
     return new DAnonymizer();//considering DAnonymizer has default constructor
  }

}
