我目前正在尝试使用 Axon 框架和 Spring Boot 实现一些应用程序，我需要为其中一个 sagas 编写单元测试。在这个传奇中，除了 axon 的功能之外，我还使用了 spring boot 存储库，我需要对其进行模拟以进行测试。

问题是，没有注入存储库 - 它始终为空。我真的很感激在这件事上的任何帮助。

@Slf4j
@Saga
@Service
public class ValidationSaga {  

    @Autowired
    private transient CommandGateway commandGateway;
    private EmployeeRepository employeeRepository;

    private String correlationId;
    private String emp1Code;
    private String emp2Code;
    private String emp1Id;
    private String emp2Id;
    private String emp3Id;
    private String emp3Code;

    @StartSaga
    @SagaEventHandler(associationProperty = "correlationId")
    public void on(NewMatchingDocumentAggregate.MatchingSubmittedEvent event) {


        log.debug(">>>    HANDLING IN SAGA");
        log.debug(">>> REPO: ", employeeRepository); //At this point repo is null

        this.correlationId = event.getCorrelationId();
        this.emp1Code= event.getEmp1Code();
        this.emp2Code= event.getEmp2Code();
        this.emp1Id= event.getEmp1Id();
        this.emp2Id= event.getEmp2Id();
        this.emp3Id= event.getEmp3Id();
        this.emp3Code= event.getEmp3Code();

        if(!employeeRepository.existsById(event.getEmp1Id())) {
            employeeRepository.save(EmployeeEntity.builder()
                .employeeCode(event.getEmp1Code())
                .employeeName(null)
                .isActive(true)
                .removeFromRole(false)
                .build());
        }

        if(!employeeRepository.existsById(event.getEmp2Id())) {
            employeeRepository.save(EmployeeEntity.builder()
                    .employeeCode(event.getEmp2Code())
                    .employeeName(null)
                    .isActive(true)
                    .removeFromMentorRole(false)
                    .build());
        }
        log.debug(">>> > before gateway");

        commandGateway.send(new NewMatchingDocumentAggregate.ApplyContextCommand(
                this.correlationId, this.emp1Code, this.emp2Code, this.emp1Id, this.emp2Id,
                this.emp3Id, this.emp3Code));
    }

    @EndSaga
    @SagaEventHandler(associationProperty = "correlationId")
    public void on(NewMatchingDocumentAggregate.MatchingDefinedEvent event) {
    }
}

测试：

@Slf4j
@RunWith(MockitoJUnitRunner.class)
public class ValidationSagaTest {

    @Mock
    private EmployeeRepository employeeRepository;
    @InjectMocks
    private ValidationSaga validationSaga;

    private FixtureConfiguration fixture;

    @Before
    public void setUp() throws Exception {

        fixture = new SagaTestFixture<>(ValidationSaga.class);
    }

    @Test
    public void shouldSendApplyContextCommand_whenEmployeesExists_givenSomeEvent() {

        val correlationId = "correlationId";
        val emp1Code = "emp1Code ";
        val emp2Code = "emp2Code ";
        val emp1Id = "emp1Id ";
        val emp2Id = "emp2Id ";
        val emp3Id = "emp3Id ";
        val emp3Code = "emp3Code ";

        when(employeeRepository.existsById(emp1Id)).thenReturn(true);
        when(employeeRepository.existsById(emp2Id)).thenReturn(true);

        fixture.givenNoPriorActivity()
                .whenAggregate(correlationId)
                .publishes(new NewMatchingDocumentAggregate.MatchingSubmittedEvent(correlationId, emp1Code,
                        emp2Code, emp1Id, emp2Id, emp3Id, emp3Code))
                .expectActiveSagas(1)

                .expectDispatchedCommands(new NewMatchingDocumentAggregate.ApplyContextCommand(correlationId,
                        emp1Code, emp2Code, emp1Id, emp2Id, emp3Id, emp3Code));

    }

Axon 中的ASaga不是 Spring 管理的 Bean，尽管使用@Autowired注解将 Bean 连接到其中的可能性确实使它看起来如此。ResourceInjector为了在你的 Saga 中连接 Bean ，框架使用SpringResourceInjector.

现在该信息不一定能解决您的问题，但可能会提示您需要做一些特定的事情来在 Saga 中注入模拟服务。为了能够使用您的模拟服务，您需要调用该SagaTestFixture#registerResource(Object)函数，其中提供Object的是您的模拟服务。

我建议将setUp()是为您的情况注册这些资源的理想场所。

希望这可以帮助！
