我有通过服务层中的springframework.data.jpa.domain.Specifications过滤选择的方法，我尝试测试它：
@Override
public Page<Phone> list(@NonNull final PhoneFilter filter) {
Specification<Phone> specs = new PhoneSpecification(filter);
return phoneRepository.findAll(where(specs), filter.getPageable());
}
但我的测试不起作用：
@Test
public void whenCallListWithEmptyFilterThenRepoIsCalledFindAll() {
PhoneFilter filter = new PhoneFilter(new PageRequest(0 , 1));
phoneService.list(filter);
PhoneSpecification spec = new PhoneSpecification(filter);
verify(phoneRepository).findAll(where(spec), filter.getPageable());
}
Argument(s) are different! Wanted:
phoneRepository bean.findAll(
org.springframework.data.jpa.domain.Specifications@47d533c0,
Page request [number: 0, size 1, sort: null]
);
-> at ru.pravvich.service.PhoneServiceImplTest.whenCallListWithEmptyFilterThenRepoIsCalledFindAll(PhoneServiceImplTest.java:80)
Actual invocation has different arguments:
phoneRepository bean.findAll(
org.springframework.data.jpa.domain.Specifications@12129ef3,
Page request [number: 0, size 1, sort: null]
);
-> at ru.pravvich.service.PhoneServiceImpl.list(PhoneServiceImpl.java:35)

Specifications对象相等，我认为这应该足够了。但实例不同：Specifications@47d533c0和Specifications@12129ef3我认为这并不重要。
为什么我的测试不起作用？以及如何解决它？

PhoneSpecification类：
@EqualsAndHashCode
@AllArgsConstructor
class PhoneSpecification implements Specification<Phone> {
private final @NonNull PhoneFilter filter;
@Override
public Predicate toPredicate(Root<Phone> root, CriteriaQuery<?> query, CriteriaBuilder cb) {
Predicate predicate = cb.conjunction();
if (nonNull(filter.id)) {
predicate.getExpressions().add(cb.equal(root.get("id"), filter.id));
}
if (nonNull(filter.note)) {
predicate.getExpressions().add(cb.like(root.get("note"), toLike(filter.note, ANY)));
}
if (nonNull(filter.number)) {
predicate.getExpressions().add(cb.like(root.get("number"), toLike(filter.number, ANY)));
}
if (nonNull(filter.status)) {
predicate.getExpressions().add(cb.like(root.get("status"), toLike(filter.status, ANY)));
}
if (nonNull(filter.opName)) {
predicate.getExpressions().add(cb.like(root.get("operatorName"), toLike(filter.opName, ANY)));
}
if (nonNull(filter.login)) {
predicate.getExpressions().add(cb.like(root.get("operatorAccLogin"), toLike(filter.login, ANY)));
}
if (nonNull(filter.password)) {
predicate.getExpressions().add(cb.like(root.get("operatorAccPassword"), toLike(filter.password, ANY)));
}
if (nonNull(filter.from) && nonNull(filter.to)) {
predicate.getExpressions().add(cb.between(root.get("regDate"), filter.from, filter.to));
}
return predicate;
}
}
并过滤：
@Data
@EqualsAndHashCode
class PhoneFilter {
private @NonNull Pageable pageable;
private Integer id;
private Timestamp from;
private Timestamp to;
private String number;
private String login;
private String password;
private String opName;
private String status;
private String note;
}
