java - hibernate.异常.SQLGrammarException : could not extract ResultSet: ORA-00942: table or view does not exist

Question

我正在开发一个 hibernate 应用程序并尝试从表(oracle sql)中提取数据。但查询结果抛出

hibernate.exception.SQLGrammarException:无法提取ResultSet:根本原因是java.sql.SQLSyntaxErrorException:ORA-00942:表或 View 不存在。

该表仍在数据库中。

这是异常的完整堆栈跟踪

Hibernate: select categorylo0_.cat_id as cat_id1_0_, categorylo0_.category_name as category_name2_0_ from test.itemcategory categorylo0_

WARN: SQL Error: 942, SQLState: 42000
Jan 31, 2017 3:36:48 PM org.hibernate.engine.jdbc.spi.SqlExceptionHelper logExceptions
ERROR: ORA-00942: table or view does not exist

这是我的实体类

@Entity
@Table(name="itemcategory")
public class CategoryLoader {

    @Id
    private String Cat_Id;

    @Column(name="category_name")
    private String Category_Name;

    public String getCat_Id() {
        return Cat_Id;
    }

    public void setCat_Id(String cat_Id) {
        Cat_Id = cat_Id;
    }

    public String getCategory_Name() {
        return Category_Name;
    }

    public void setCategory_Name(String category_Name) {
        Category_Name = category_Name;
    }
}

这是dao实现的代码

session.getCurrentSession().createQuery("from CategoryLoader").list();

这是配置

<bean id="sessionFactory"
    class="org.springframework.orm.hibernate5.LocalSessionFactoryBean">
    <property name="dataSource" ref="dataSource" />
    <property name="hibernateProperties">
        <props>
            <prop key="hibernate.dialect">org.hibernate.dialect.Oracle10gDialect</prop>

Answer 1

确保您的数据库用户拥有适当的权限来实际访问相关表；似乎如果缺少补助金，您也会得到 ORA-00942。执行类似的事情

将myTablename上的选择授予myUser；

不要忘记您可能还需要的其他授权类型(DELETE、INSERT、UPDATE 等)
