没有这样的方法错误在电源模拟弹簧启动?

Question

试图模拟私有方法"mapCustomerToRule"与PowerMockito Spy在同一类中，但无法获得它。虽然它给出了NoSuchMethodError。

但它仍然进行私有方法调用，进而进行另一个第三方部分调用。当第三方呼叫引发异常时，我遇到了问题。据我了解，如果我在模拟"mapCustomerToRule"，它不应该进入方法实现细节并返回模拟响应。

public Map<String, List<Rule>> fetchCutomerToRules() {
List<ClaimRuleEntity> listOfDHLClaimsRule = dhlClaimRuleRepository.findAllByOrderByRulePriority();
if (Objects.isNull(listOfDHLClaimsRule) || listOfDHLClaimsRule.isEmpty()) {
return null;
}
log.info("claim rules fetched from database");
List<ClaimRuleCustomerEntity> listOfDHLClaimRuleCustomerEntity = dhlClaimRuleCustomerRepository.findAllByEnabledFlagTrue();
if (Objects.isNull(listOfDHLClaimRuleCustomerEntity) || listOfDHLClaimRuleCustomerEntity.isEmpty()) {
return null;
}
log.info("claim customers fetched from database");
return mapCustomerToRule(listOfDHLClaimsRule, listOfDHLClaimRuleCustomerEntity);
}
private Map<String, List<Rule>> mapCustomerToRule(List<ClaimRuleEntity> listOfDHLClaimsRule,
List<ClaimRuleCustomerEntity> listOfDHLClaimRuleCustomerEntity) {
log.info("mapping started for claim rules to customer");
Map<String, List<Rule>> cutomerToRules = new HashMap<>();
listOfDHLClaimRuleCustomerEntity.forEach(dhlClaimRuleCustomerEntity -> {
String customer = dhlClaimRuleCustomerEntity.getCustomer();
List<Rule> rules = cutomerToRules.get(customer);
if (Objects.isNull(rules)) {
rules = new ArrayList<>();
cutomerToRules.put(customer, rules);
}
for (ClaimRuleEntity dhlClaimRule : listOfDHLClaimsRule) {
if (dhlClaimRule.getRuleId() == dhlClaimRuleCustomerEntity.getRuleId()) {
Rule rule = new Rule();
rule.setRuleId(dhlClaimRule.getRuleId());
rule.setRuleValue(dhlClaimRuleCustomerEntity.getRuleValue());
rule.setRulePriority(dhlClaimRule.getRulePriority());
rule.setEnabled(dhlClaimRuleCustomerEntity.getEnabledFlag());
rule.setRuleDescription(dhlClaimRule.getRuleDescription());
rules.add(rule);
break;
}
}
});
log.info("mapping completed for claim rules to customer");
return cutomerToRules;
}

这是我为课堂写的丝

@RunWith(PowerMockRunner.class)
@PowerMockRunnerDelegate(SpringRunner.class)
@PrepareForTest(FetchUpdateClaimService.class)
@ContextConfiguration(classes = ProcessClaimTestConfiguration.class)
public class FetchUpdateClaimServiceTest {
@Autowired
FetchUpdateClaimService fetchUpdateClaimService;
@Autowired
ClaimRuleRepository dhlClaimRuleRepository;
@Autowired
ClaimRuleCustomerRepository dhlClaimRuleCustomerRepository;
@Autowired
ClaimRepository dhlClaimRepository;
@Before
public void init() {
MockitoAnnotations.initMocks(this);
}
@Test
public void fetchCutomerToRules_should_pass_Test() throws Exception {
FetchUpdateClaimService fetchUpdateClaimService = PowerMockito.spy(this.fetchUpdateClaimService);
List<ClaimRuleEntity> listOfDHLClaimsRule = new ArrayList<>();
ClaimRuleEntity claimRuleEntity = new ClaimRuleEntity();
listOfDHLClaimsRule.add(claimRuleEntity);
List<ClaimRuleCustomerEntity> listOfDHLClaimRuleCustomerEntity = new ArrayList<>();
ClaimRuleCustomerEntity claimRuleCustomerEntity = new ClaimRuleCustomerEntity();
listOfDHLClaimRuleCustomerEntity.add(claimRuleCustomerEntity);
Map<String, List<Rule>> map = new HashMap<>();
Mockito.when(dhlClaimRuleRepository.findAllByOrderByRulePriority()).thenReturn(listOfDHLClaimsRule);
Mockito.when(dhlClaimRuleCustomerRepository.findAllByEnabledFlagTrue()).thenReturn(listOfDHLClaimRuleCustomerEntity);
PowerMockito.doReturn(map).when(fetchUpdateClaimService,"mapCustomerToRule",Mockito.eq(List.class),Mockito.eq(List.class));
this.fetchUpdateClaimService.fetchCutomerToRules();
}
}
