HSQLDB：org.dbunit.dataset.DataSetException：java.sql.SQLSyntaxErrorException：用戶缺少特權或找不到對象：TRIGGER_CATALOG

Question

我是想在我們的項目中使用DbUnit和正在運行到一個問題。想知道你是否能夠提供幫助。

使用@ExpectedDatabase（「file.xml」）的註釋，並且在處理該林，林在這個執行點：

我在file.xml多個表，其中兩個是組織和觸發。 正在處理組織表時，在此行返回的元數據對象恰好有3列：organization_id，名稱和狀態。這些是我的組織表所具有的3列。

但在處理觸發器，在相同的執行點，元數據爲空，所以它執行進一步線299，並呼籲：

// Create metadata and cache it 
metaData = new DatabaseTableMetaData(tableName, _connection, true, super.isCaseSensitiveTableNames()); 

返回這個元數據有很多，我不列有我的表（TRIGGER_CATALOG，EVENT_MANIPULATION，ACTION_TIMING等）

預計列（我在架構有這些）：

TRIGGER_ID 
TRIGGER_EXTERNAL_ID 
TRIGGER_NAME (First occurrence. See below) 
STATUS 
CREATED_BY 
CREATED_ON 
UPDATED_BY 
UPDATED_ON 

未知科拉姆NS（我沒有這在我的架構）：

TRIGGER_CATALOG 
TRIGGER_SCHEMA 
TRIGGER_NAME (Yes, This appears twice on the meta data. On the top probably from my schema, and here from reserved info/magic??) 
EVENT_MANIPULATION 
EVENT_OBJECT_CATALOG 
EVENT_OBJECT_SCHEMA 
EVENT_OBJECT_TABLE 
ACTION_ORDER 
ACTION_CONDITION 
ACTION_STATEMENT 
ACTION_ORIENTATION 
ACTION_TIMING 
ACTION_REFERENCE_OLD_TABLE 
ACTION_REFERENCE_NEW_TABLE 
ACTION_REFERENCE_OLD_ROW 
ACTION_REFERENCE_NEW_ROW 
CREATED 

由於這一點，它拋出一個異常：

org.dbunit.dataset.DataSetException: java.sql.SQLSyntaxErrorException: user lacks privilege or object not found: TRIGGER_CATALOG 
    at org.dbunit.database.DatabaseDataSet.getTable(DatabaseDataSet.java:323) 
    at com.github.springtestdbunit.assertion.NonStrictDatabaseAssertion.assertEquals(NonStrictDatabaseAssertion.java:43) 
    at com.github.springtestdbunit.DbUnitRunner.verifyExpected(DbUnitRunner.java:130) 
    at com.github.springtestdbunit.DbUnitRunner.afterTestMethod(DbUnitRunner.java:70) 
    at com.github.springtestdbunit.DbUnitTestExecutionListener.afterTestMethod(DbUnitTestExecutionListener.java:165) 

這是發生因爲即時通訊用的是「觸發器」我的表名？觸發器是DBUnit還是HSQLDB中的保留關鍵字？如果我查看DatabaseDataSet._tableMap hashmap中的其他表，所有其他表似乎都很健康，並且在我們對應的元數據對象中包含了我期望的列。 即時通訊使用Maven的項目有：

<dependency> 
     <groupId>junit</groupId> 
     <artifactId>junit</artifactId> 
     <version>4.11</version> 
    </dependency>

     <artifactId>spring-test-dbunit</artifactId> 
     <version>1.1.0</version> 
    </dependency> 

任何幫助將不勝感激。

我的測試類是什麼樣子：

public class TriggerServiceTest extends DBBaseTest { 
    @Autowired 
    private TriggerService triggerService; 
    @Test 
    @DatabaseSetup(value={"classpath:testData/trigger/Trigger_Test_2_Init.xml"}, type = DatabaseOperation.CLEAN_INSERT) 
    @ExpectedDatabase(value="classpath:testData/trigger/Trigger_Test_2.xml", assertionMode = DatabaseAssertionMode.NON_STRICT) 
    @DatabaseTearDown(value={"classpath:testData/trigger/Trigger_Test_2_Init.xml"}, type = DatabaseOperation.DELETE) 
    public void testTriggerWrite(){ 
     TriggerDTO triggerDTO = new TriggerDTO(); 
     triggerDTO.setName("Trigger_Test_1"); 
     triggerDTO.setId("101"); 
     String newId = triggerService.write(triggerDTO); 
     System.out.println("Done."); 
    } 
} 

而且DBBaseTest：

@RunWith(SpringJUnit4ClassRunner.class) 
@ContextConfiguration(locations = {"classpath:wfxSpringDatabaseTest.xml" , "classpath:wfxTriggerContextTest.xml"}) 
public abstract class DBBaseTest extends AbstractJUnit4SpringContextTests { 
    @Before 
    public void setApplicationContext() { 
     ApplicationContextHolder.setTheGlobalAppContext(applicationContext); 
    } 
} 

TESTDATA /觸發/ Trigger_Test_2.xml：

<?xml version='1.0' encoding='UTF-8'?> 
<dataset> 
    <organization organization_id="1" name="MyOrg" status="Active"/> 
    <users user_id="1" username="admin" password="pwd123" email="abc@abc.com" full_name="The Admin" status="Active" created_on="2013-08-17 03:45:44.0" created_by="1" is_admin="1" secret_question="What is your favorite sport?" secret_answer="Quiddich" enabled="1" organization_id="1"/> 
    <triggers trigger_id="101" trigger_EXTERNAL_id="101" trigger_name="Trigger_101" status="Active" created_by="1" created_on="2014-08-26 11:34:25.625" updated_by="1" updated_on="2014-08-26 11:34:25.625"/> 
</dataset> 

TESTDATA /觸發/ Trigger_Test_2_Init.xml：

<?xml version='1.0' encoding='UTF-8'?> 
<dataset> 
    <organization organization_id="1" name="MyOrg" status="Active"/> 
    <users user_id="1" username="admin" password="pwd123" email="abc@abc.com" full_name="The Admin" status="Active" created_on="2013-08-17 03:45:44.0" created_by="1" is_admin="1" secret_question="What is your favorite sport?" secret_answer="Quiddich" enabled="1" organization_id="1"/> 
    <triggers/> 
</dataset> 

Answer 1

確認這是發生由於「觸發器」字。這可能是HSQLDB中的保留關鍵字。將其更改爲「triggers_table」後，一切正常。請參考以下鏈接，所有保留的關鍵字在HSQLDB：
