powermock spring boot中的NoSuchMethodError？

Question

尝试模拟私有方法＆＃34; mapCustomerToRule＆＃34;和PowerMockito Spy在同一个班级，但无法得到它。虽然它给出NoSuchMethodError。

但它仍然使私有方法调用，而这又调用另一个thirdPartCall。当thirdPartyCall抛出异常时，我遇到了问题。据我了解，如果我嘲笑＆＃34; mapCustomerToRule＆＃34;，它就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;

}

这是我为班级写的juint

@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();

    }

}
