如何在Spring中通过@JsonTest测试自定义对象？

我有我的桌面到我必须测试的类（我想我应该）。我在互联网上发现了这个主题：但并没有解释如何测试我的主类包含的自定义类。要明确的是：

我的办公桌：

public class DeskDTO {

    private Long deskId;
    private String deskNumber;
    private String additionalNote;
    private LocalizationDTO localization;
    private Set<ElectronicEquipmentDTO> electronicEquipments; 

当我使用.extractingJsonPathMapValue时，我得到：

java.lang.AssertionError: Expected a string at JSON path "@.localization" but found: {floor={floorId=null, floorNumber=4, building={buildingId=null, nameOfBuilding=Building D}}, xAxis=5, yAxis=6}

org.opentest4j.AssertionFailedError: 
Expecting:
 <{"floor"={"building"={"buildingId"=null, "nameOfBuilding"="Building D"}, "floorId"=null, "floorNumber"=4}, "xAxis"=5, "yAxis"=6}>
to be equal to:
 <com.mrfisherman.relice.Dto.LocalizationDTO@2aafa84f>
but was not.
Expected :com.mrfisherman.relice.Dto.LocalizationDTO@2aafa84f
Actual   :{floor={floorId=null, floorNumber=4, building={buildingId=null, nameOfBuilding=Building D}}, xAxis=5, yAxis=6}

org.opentest4j.AssertionFailedError:
期望：
等于：
但事实并非如此。
应为：com.mrfisherman.relice.Dto。LocalizationDTO@2aafa84f
实际：{floor={floorrid=null，floorNumber=4，building={buildingId=null，building=building D}}，xAxis=5，yAxis=6}

什么是

JacksonTester

？

.extractingJsonPathStringValue（“@.localization”）

这将返回一个

字符串

值，然后您尝试使用

isEqualTo

将其与

对象

进行比较。您不能将

字符串

与

对象

进行比较，而是将

字符串

与

字符串

进行比较。那么如何比较这两个字符串呢？如果要比较json字符串，可以使用

objectMapper.35; writeValueAsString

将对象转换为json字符串，然后比较字符串

org.opentest4j.AssertionFailedError: 
Expecting:
 <{"floor"={"building"={"buildingId"=null, "nameOfBuilding"="Building D"}, "floorId"=null, "floorNumber"=4}, "xAxis"=5, "yAxis"=6}>
to be equal to:

but was not.
Expected :com.mrfisherman.relice.Dto.LocalizationDTO@2aafa84f
Actual   :{floor={floorId=null, floorNumber=4, building={buildingId=null, nameOfBuilding=Building D}}, xAxis=5, yAxis=6}
