Question

我有一个类，该类具有执行循环的方法：

private final ContactServiceConnector contactServiceConnector;
private final ContractServiceConnector contractServiceConnector;
private final PropertyServiceConnector propertyServiceConnector;

private void prepareCrmContactFields(final CrmApiModel crmApiModel, final JsonNode message, final String[] properties) {

    try {
        JsonNode node = null;
        String lastServiceController = "";

        for(final String s : properties ) {
            final String[] keyVal = s.split(":");
            final String actualQbeeProperty = keyVal[3];

            switch(keyVal[1]) {
                case "user":
                case "member":
                    if( node == null || !"user".equals(lastServiceController) ) {
                        node = contactServiceConnector.getUserById(userId);
                        LOGGER.debug("node = " + mapper.writerWithDefaultPrettyPrinter().writeValueAsString(node));
                        lastServiceController = keyVal[1];
                    }
                    break;
                case "building":
                    if( node == null || !"building".equals(lastServiceController) ) {
                        node = propertyServiceConnector.getBuildingById(message.get("buildingId").asLong());
                        LOGGER.debug("node = " + mapper.writerWithDefaultPrettyPrinter().writeValueAsString(node));
                        lastServiceController = keyVal[1];
                    }
                    break;
                default:
                    lastServiceController = keyVal[1];
                    crmApiModel.addProperty(new CrmApiModelProperty(keyVal[0],
                            keyVal[2].isEmpty() ? message.get(keyVal[3]).asText() : node.path(keyVal[2]).get(keyVal[3]).asText()));
                    continue;
            }

            crmApiModel.addProperty(new CrmApiModelProperty(keyVal[0],
                    keyVal[2].isEmpty() ? node.get(keyVal[3]).asText() : node.path(keyVal[2]).get(keyVal[3]).asText()));
            }// end for
        } catch (InternalCommunicationException e) {
            e.printStackTrace();
            throw e;
        } catch (Exception hceEx) {
            throw hceEx;
        }
    }
}

在我的测试课中，我对此进行了定义：

@MockBean
private ContractServiceConnector contractServiceConnector;
@MockBean
private ContactServiceConnector contactServiceConnector;
@MockBean
private PropertyServiceConnector propertyServiceConnector;

@Test
@Tag("slow")
@Tag("integration")
void publishMessage() throws IOException, InternalCommunicationException, InterruptedException {
    Mockito.doReturn(user)    .when(contactServiceConnector) .getUserById    (Mockito.any(Long.class));
    Mockito.doReturn(building).when(propertyServiceConnector).getBuildingById(Mockito.any(Long.class));
    Mockito.doReturn(contract).when(contractServiceConnector).getContractById(Mockito.any(Long.class));
    ...
}

模拟值是这样的：

private JsonNode user = mapper.readTree("{...}");
private JsonNode building = mapper.readTree("{...}");
private JsonNode contract = mapper.readTree("{...}");

具有最初从xyzServiceConnector.getXyzById(id);返回的值的结构

当我开始测试publishMessage方法时，有时会使用模拟值设置节点，但通常是null。我误解了嘲笑还是我在做哪个错误？？

为什么Mockito.doReturn（）有时返回null？
