无法处理Point(原因：java.lang.InstantiationError:org.locationtech.jts.geom.CoordinateSequence)在Sping Boot 的JUnit测试中的应用

我尝试在Sping Boot 中使用Point来实现junit测试。我完成了junit测试，但在AssignmentEntityBuilder的generateValidUserEntities方法中处理Point问题时遇到了问题。
我该如何解决？
下面是AssignmentEntity

...
public class AssignmentEntity extends BaseEntity {

    ...
    
    public void setPoint(double latitude, double longitude) {
        Coordinate coordinate = new Coordinate(latitude, longitude);
        GeometryFactory geometryFactory = new GeometryFactory();
        this.point = geometryFactory.createPoint(coordinate);
    }

}

下面是AssignmentEntityBuilder

public class AssignmentEntityBuilder extends TestDataBuilder<AssignmentEntity> {

    public AssignmentEntityBuilder() {
        super(AssignmentEntity.class);
    }

    public static List<AssignmentEntity> generateValidUserEntities(int size) {
        List<AssignmentEntity> userEntities = new ArrayList<>();
        for (int i = 0; i < size; i++) {
            AssignmentEntity assignmentEntity = new AssignmentEntityBuilder().withValidFields().build();
            userEntities.add(assignmentEntity);
        }
        return userEntities;
    }

    public AssignmentEntityBuilder withValidFields() {
        InstitutionEntity institutionEntity = new InstitutionEntityBuilder().withValidFields().build();

        double x = Math.random();
        double y = Math.random();
        Point point = new GeometryFactory().createPoint(new Coordinate(x, y));

        return this
                .withId(AysRandomUtil.generateUUID())
                .withInstitutionId(institutionEntity.getId())
                .withInstitution(institutionEntity)
                .withPhoneNumber(new AysPhoneNumberBuilder().withValidFields().build())
                .withDescription("Description")
                .withFirstName("First Name")
                .withLastName("Last Name")
                .withStatus(AssignmentStatus.AVAILABLE)
                .withPoint(point);
    }

    public AssignmentEntityBuilder withId(String id) {
        data.setId(id);
        return this;
    }

    public AssignmentEntityBuilder withInstitutionId(String institutionId) {
        data.setInstitutionId(institutionId);
        return this;
    }

    public AssignmentEntityBuilder withPhoneNumber(AysPhoneNumber phoneNumber) {
        data.setCountryCode(phoneNumber.getCountryCode());
        data.setLineNumber(phoneNumber.getLineNumber());
        return this;
    }

    public AssignmentEntityBuilder withInstitution(InstitutionEntity institution) {
        data.setInstitution(institution);
        return this;
    }

    public AssignmentEntityBuilder withDescription(String description) {
        data.setDescription(description);
        return this;
    }

    public AssignmentEntityBuilder withFirstName(String firstName) {
        data.setFirstName(firstName);
        return this;
    }

    public AssignmentEntityBuilder withLastName(String lastName) {
        data.setLastName(lastName);
        return this;
    }

    public AssignmentEntityBuilder withStatus(AssignmentStatus status) {
        data.setStatus(status);
        return this;
    }

    public AssignmentEntityBuilder withPoint(Point point) {
        data.setPoint(point);
        return this;
    }

}

下面是服务类

class AssignmentSaveServiceImplTest extends AbstractUnitTest {

    @InjectMocks
    private AssignmentSaveServiceImpl assignmentSaveService;

    @Mock
    private AssignmentRepository assignmentRepository;

    @Mock
    private AysIdentity identity;

    @Test
    void givenValidAssignmentSaveRequest_whenAssignmentSaved_thenReturnAssignment() {

        // Given
        AssignmentSaveRequest mockAssignmentSaveRequest = new AssignmentSaveRequestBuilder()
                .withValidFields()
                .build();

        List<AssignmentEntity> assignmentsFromDatabase = AssignmentEntityBuilder.generateValidUserEntities(10);  --- ERROR LINE

        AssignmentEntity mockAssignmentEntity = new AssignmentEntityBuilder()
                .withValidFields().build();

        // When
        Mockito.when(assignmentRepository.findAll())
                .thenReturn(assignmentsFromDatabase);

        Mockito.when(assignmentRepository.save(Mockito.any(AssignmentEntity.class)))
                .thenReturn(mockAssignmentEntity);

        Mockito.when(identity.getInstitutionId())
                .thenReturn(AysRandomUtil.generateUUID());

        // Then
        Assignment assignment = assignmentSaveService.saveAssignment(mockAssignmentSaveRequest);

        Assertions.assertEquals(mockAssignmentSaveRequest.getFirstName(), assignment.getFirstName());
        Assertions.assertEquals(mockAssignmentSaveRequest.getLastName(), assignment.getLastName());
        Assertions.assertEquals(mockAssignmentSaveRequest.getPhoneNumber().getLineNumber(), assignment.getPhoneNumber().getLineNumber());
        Assertions.assertEquals(mockAssignmentSaveRequest.getPhoneNumber().getCountryCode(), assignment.getPhoneNumber().getCountryCode());
        Assertions.assertEquals(mockAssignmentSaveRequest.getDescription(), assignment.getDescription());
        Assertions.assertEquals(mockAssignmentSaveRequest.getDescription(), assignment.getDescription());
        Assertions.assertEquals(mockAssignmentSaveRequest.getLongitude(), assignment.getLongitude());
        Assertions.assertEquals(mockAssignmentSaveRequest.getLatitude(), assignment.getLatitude());

        Mockito.verify(assignmentRepository, Mockito.times(1)).findAll();
        Mockito.verify(identity, Mockito.times(1)).getInstitutionId();
    }
}

下面是显示的错误

下面是解决方案展示

**1 -**从AbstractRandomizer扩展定义一个名为PointRandomizer的类，随机生成Point。

class PointRandomizer extends AbstractRandomizer<Point> {

    @Override
    public Point getRandomValue() {
        Coordinate[] coordinates = new Coordinate[]{new Coordinate(40.991739, 29.024168)};
        CoordinateSequence coordinateSequence = new CoordinateArraySequence(coordinates);
        GeometryFactory geometryFactory = new GeometryFactory();
        return geometryFactory.createPoint(coordinateSequence);
    }
}

**2 -**定义一个名为PointRandomizer的静态final变量

private static final PointRandomizer POINT_RANDOMIZER = new PointRandomizer();

**3 -**将POINT_RANDOMIZER与EasyRandomParameters相加，随机产生点值

parameters.randomize(Point.class, POINT_RANDOMIZER);

下面是最终的TestBuilder类

public abstract class TestDataBuilder<T> {
    protected final EasyRandom generator;
    protected T data;
    protected Class<T> clazz;
    private static final PositiveIntegerRandomizer POSITIVE_INTEGER_RANDOMIZER = new PositiveIntegerRandomizer();
    private static final LongRangeRandomizer LONG_RANGE_RANDOMIZER = new LongRangeRandomizer(1L, Long.MAX_VALUE);
    private static final CharacterRandomizer CHARACTER_RANDOMIZER = new CharacterRandomizer();

    private static final PointRandomizer POINT_RANDOMIZER = new PointRandomizer();

    public TestDataBuilder(Class<T> clazz) {
        this(clazz, false);
    }
    public TestDataBuilder(Class<T> clazz, boolean excludeRelations) {
        this.clazz = clazz;
        this.generator = new EasyRandom(this.getExclusionParameters(excludeRelations));
        this.data = generator.nextObject(clazz);
    }
    public T build() {
        return data;
    }
    private EasyRandomParameters getExclusionParameters(boolean excludeRelations) {
        EasyRandomParameters parameters = new EasyRandomParameters();
        parameters.randomize(Integer.class, POSITIVE_INTEGER_RANDOMIZER);
        parameters.randomize(String.class, CHARACTER_RANDOMIZER);
        parameters.randomize(Long.class, LONG_RANGE_RANDOMIZER);
        parameters.randomize(Point.class, POINT_RANDOMIZER);

        if (!excludeRelations) return parameters;

        parameters.excludeField(
                FieldPredicates.isAnnotatedWith(ManyToOne.class, OneToMany.class, OneToOne.class)
                        .or(named("id"))
        );
        return parameters;
    }
}
class PositiveIntegerRandomizer extends IntegerRangeRandomizer {
    private static final int MIN = 0;
    private static final int MAX = 100;
    public PositiveIntegerRandomizer() {
        super(MIN, MAX);
    }
    @Override
    protected Integer getDefaultMinValue() {
        return MIN;
    }
}
class CharacterRandomizer extends StringRandomizer {
    @Override
    public String getRandomValue() {
        return RandomStringUtils.randomAlphabetic(10);
    }
}

class PointRandomizer extends AbstractRandomizer<Point> {

    @Override
    public Point getRandomValue() {
        Coordinate[] coordinates = new Coordinate[]{new Coordinate(40.991739, 29.024168)};
        CoordinateSequence coordinateSequence = new CoordinateArraySequence(coordinates);
        GeometryFactory geometryFactory = new GeometryFactory();
        return geometryFactory.createPoint(coordinateSequence);
    }
}
