org.hibernate.util.JDBCExceptionReporter - 用戶缺少權限或對象未找到

Question

堆棧跟蹤：WARN org.hibernate.util.JDBCExceptionReporter - SQL錯誤：-5501，SQLState：42501 錯誤org.hibernate.util.JDBCExceptionReporter - 用戶缺少特權或找不到對象：TEST_CASE

我的applicationContext-的JUnit的test.xml文件：

TestCase.java file: 


    @Entity 
    @Table(name = "test_case", schema = "testcase") 
    @JsonSerialize(include = JsonSerialize.Inclusion.NON_NULL) 
    @XmlRootElement 
    public class TestCase implements Serializable { 

     @Id 
     @GeneratedValue(strategy = GenerationType.AUTO) 
     @Column(name = "ID", nullable = false) 
     private Long Id; 

     public Long getId() { 
      return Id; 
     } 
     public void setId(Long id) { 
      Id = id; 
     } 
    } 

**DBUtil.java** runs the DDL and DML hsql files and DB is created successfully(I have printed DB on console). 

     public class DBUtil { 
       public static void createTestSchema() { 
        String sqlPath = "src/test/resources/sql"; 
         ApplicationContext dbCtx = new ClassPathXmlApplicationContext("applicationContext-junit-test.xml"); 
       BasicDataSource ds = dbCtx.getBean(BasicDataSource.class); 
       Connection conn = ds.getConnection(); 
         Statement st = null; 
        try { 
         System.out.println("Creating Schema !"); 
         File dir = new File(sqlPath); 
         File[] files = dir.listFiles(); 
         SqlFile sqlFile; 
         for (File file : files) { 
           sqlFile = new SqlFile(file); 
           sqlFile.setConnection(conn); 
           sqlFile.execute(); 
          } 
         } 
    } 

DaoImpl.java
我的HQL查詢獲取的結果爲零（如果我設置hbm2ddl.auto作爲「創建」） 我的HQL查詢拋出JDBCExceptionReporter：用戶缺少特權或找不到對象（如果我不使用hbm2ddl.auto屬性）

public class DaoImpl implements Dao { 
    @Autowired 
    private SessionFactory sessionFactory; 

    public void getAllData(){ 

     String hql = "FROM TestCase"; 
     Session session = sessionFactory.openSession(); 
     List<TestCase> results; 
     try { 
      Query query = session.createQuery(hql); 
      results = query.list(); // list is empty : [] 

     } catch (Exception e) { 

     } 
    } 
} 

Answer 1

來自TestCase.java

我刪除了@Table中的模式，它工作。我也刪除了在DDL和類似引用中創建模式。

所以更新TestCase.java將看起來像：

@Entity 
@Table(name = "test_case") 
@JsonSerialize(include = JsonSerialize.Inclusion.NON_NULL) 
@XmlRootElement 
public class TestCase implements Serializable { 

    @Id 
    @GeneratedValue(strategy = GenerationType.AUTO) 
    @Column(name = "ID", nullable = false) 
    private Long Id; 

    public Long getId() { 
     return Id; 
    } 
    public void setId(Long id) { 
     Id = id; 
    } 
} 

Answer 2

你的數據庫URL屬性是不對的內存數據庫。和MEM：一個文件正確的使用性能的數據庫如下：

<property name="url"> 
     <value>jdbc:hsqldb:file:testcasedb;shutdown=true;hsqldb.write_delay=false;</value> 

    <property name="url"> 
     <value>jdbc:hsqldb:mem:testcasedb</value> 

如果您使用shutdown =真用MEM：數據庫中的所有數據，只要最後一個打開的連接關閉刪除。使用文件數據庫，所有數據都會保存。
