嘲諷JdbcTemplate.queryForObject（...，...，...）與1.9.5的Mockito

我的問題是類似this SO question 嘲諷JdbcTemplate.queryForObject（...，...，...）與1.9.5的Mockito

我有類似下面服務中有兩個JdbcTemplate.queryForObject(..,...,...,)電話，

depositPostedAmt = jdbcTemplate.queryForObject(Constants.FETCH_DEPOSIT_POSTED_AMT, BigDecimal.class,new Object[] { remitBean.getDepositId() });

和

claimPostedAmt =jdbcTemplate.queryForObject(Constants.FETCH_CLAIM_POSTED_AMOUNT,BigDecimal.class, new Object[] { claim.getClaimId(), remitBean.getContractNum() });

第三個參數，new Object[]是這兩個電話和實際的SQL字符串不同而不同。所以我試圖用不同的戲弄在兩種情況下返回兩個不同的對象，如下圖所示，

when(jdbcTemplate.queryForObject(eq(Constants.FETCH_DEPOSIT_POSTED_AMT), eq(BigDecimal.class), anyObject())).thenReturn(depositPostedAmt); 


when(jdbcTemplate.queryForObject(eq(Constants.FETCH_CLAIM_POSTED_AMOUNT), eq(BigDecimal.class), anyObject())).thenReturn(claimPostedAmt);

即我想在兩個不同的查詢，接收兩個不同BigDecimal。

我收到depositPostedAmt如預期，但claimPostedAmt總是空，即使我在@Before方法相同depositPostedAmt所以我猜測，我when匹配沒有發現任何比賽都初始化它。我已經嘗試了第三個參數匹配的各種語法，如any(Object[].class)和anyRef(objectArray)等，但第二次，我總是得到NULL。

我不知道我缺少什麼，因爲沒有錯誤。我正在使用JUnit以及Mockito 1.9.5。

這裏是示例代碼 - 一切正常，但claimPostedAmt在被調用的服務中保持爲空。

@RunWith(SpringJUnit4ClassRunner.class) 
@ContextConfiguration(classes = TestConfig.class, loader = AnnotationConfigContextLoader.class) 
public class RCMatchDaoImplTest{ 

    @Autowired private RCMatchDaoImpl service; 
    @Autowired private JdbcTemplate jdbcTemplate; 
    @Autowired private Logger logger; 

    private RemitBean remitBean; 
    private List<RemitBean> remitBeanList; 
    private BigDecimal depositPostedAmt,claimPostedAmt,remitAmount; 
    private ClaimVO claim; 
    private List<ClaimVO> claims; 


    @Before 
    public void setUp() throws NoSuchFieldException, SecurityException, Exception{ 
     /* Set dependencies*/ 
     service.setJdbcTemplate(jdbcTemplate); 
     setFinalStatic(RCMatchDaoImpl.class.getDeclaredField("logger"),logger); 

     remitBean = new RemitBean(); 
     remitBeanList=new ArrayList<>(); 
     claim= new ClaimVO(); 
     claims= new ArrayList<>(); 

     remitBeanList.add(remitBean); 
     depositPostedAmt=new BigDecimal(-10); 
     claimPostedAmt = new BigDecimal(-10); 
     remitAmount=new BigDecimal(20); 
     claims.add(claim); 
    } 

    private static void setFinalStatic(Field field, Object newValue) throws Exception{ 
     field.setAccessible(true);   
     Field modifiersField = Field.class.getDeclaredField("modifiers"); 
     modifiersField.setAccessible(true); 
     modifiersField.setInt(field, field.getModifiers() & ~Modifier.FINAL); 
     field.set(null, newValue); 
    } 

    @Test 
    public void testLucenePost_refund_success() throws SQLException{ 

     /* Set Data */ 
     remitBean.setRemitType("R"); 
     remitBean.setRemitAmt(remitAmount); 
     remitBean.setDepositId(6866418); 
     remitBean.setClaims(claims); 

     depositPostedAmt=depositPostedAmt.add(new BigDecimal(20)); 
     claimPostedAmt=claimPostedAmt.add(new BigDecimal(10)); 

     claim.setClaimId(6866418); 
     claim.setContractNum("100"); 

     Object[] depositParams = new Object[] { 6866418 }; 
     Object[] claimParams = new Object[] { 6866418,"100" }; 

     /* Record Invocations*/ 

     when(jdbcTemplate.queryForObject(eq(Constants.FETCH_DEPOSIT_POSTED_AMT), eq(BigDecimal.class), anyObject())).thenReturn(depositPostedAmt); 
     when(jdbcTemplate.queryForObject(eq(Constants.FETCH_CLAIM_POSTED_AMOUNT), eq(BigDecimal.class), anyObject())).thenReturn(claimPostedAmt); 
     doNothing().when(logger).error(anyString()); 

     /* Play the Service */ 
     service.lucenePost(remitBeanList); 

     /* Verify Results */ 

     /* reset data to original value as in SetUp method*/ 
    }

只是爲了完整起見，這裏是我的上下文類也

import org.mockito.Mock; 
import org.mockito.MockitoAnnotations; 
import org.slf4j.Logger; 
import org.springframework.context.annotation.Bean; 
import org.springframework.context.annotation.Configuration; 
import org.springframework.jdbc.core.JdbcTemplate; 



@Configuration 
public class TestConfig { 

    @Mock JdbcTemplate jdbcTemplate; 
    @Mock Logger logger; 

    TestConfig(){ 
     MockitoAnnotations.initMocks(this); 
    } 

    @Bean 
    public RCMatchDaoImpl getRCMatchDaoImpl() { 
     return new RCMatchDaoImpl(); 
    } 

    @Bean 
    public JdbcTemplate jdbcTemplate(){ 
     return jdbcTemplate; 
    } 

    @Bean 
    public Logger logger(){ 
     return logger; 
    } 
}

我們可以看到整個測試（也許你可以張貼一些[MCVE]）？ –

@AdrianShum - 不，在實際的方法調用中，它不是「BigDecimal」的Object實例，而是「.class」參數。 –

雅，發現立即評論並立即刪除評論：P –

我也用這個（與19年1月10日的Mockito）：

when(jdbcTemplate.queryForObject(eq(Constants.FETCH_DEPOSIT_POSTED_AMT), eq(BigDecimal.class), anyVararg())).thenReturn(depositPostedAmt); 
when(jdbcTemplate.queryForObject(eq(Constants.FETCH_CLAIM_POSTED_AMOUNT), eq(BigDecimal.class), anyVararg())).thenReturn(claimPostedAmt);

和工作如預期。輸出：

10 
0

如預期的那樣。

一些閱讀：http://site.mockito.org/mockito/docs/current/org/mockito/ArgumentMatchers.html#anyVararg()

我在1.9.5上，'anyVararg（）'給了我這個錯誤，'參數是不同的！通緝： jdbcTemplate.queryForObject（「Query」， class java.math.BigDecimal，）; - > at com.hmsy.bp.dao.RCMatchDaoImplTest.testLucenePost_refund_success（RCMatchDaoImplTest。的java：110）實際調用具有不同的參數： jdbcTemplate.queryForObject（「查詢」，類java.math.BigDecimal， 6866418，空）;' –

所以額外的參數 - 'remitBean.getContractNum（）'導致失敗。如果我在服務代碼中刪除'remitBean.getContractNum（）'，它就可以工作。那麼'anyObject（）'也可以。數組中的兩個對象造成了不同。 –

「給我這個錯誤，參數是不同的！」來自一些'verify（）'！ –
