Question

我有mysql db，我从中生成了hibernate实体，现在我需要从这些实体生成内存数据库进行测试。我在尝试运行单元测试时遇到此错误。

/ *** main] o.h.engine.jdbc.spi.SqlExceptionHelper：SQL错误：42102，SQLState：42S02 2016-02-16 18：10：47.864 ERROR 29758 --- [main] o.h.engine.jdbc.spi.SqlExceptionHelper：Table＆＃34; tbl_all_orders＆＃34;未找到; SQL语句： ** /

看起来db创建失败了。

这是我的测试属性文件内容：

db.driver: org.h2.Driver
db.url: jdbc:h2:mem:testdb;MODE=MySQL;DB_CLOSE_DELAY=-1;DB_CLOSE_ON_EXIT=FALSE;DATABASE_TO_UPPER=false
db.username: sa
db.password: 

hibernate.dialect: org.hibernate.dialect.H2Dialect
hibernate.show_sql: true
hibernate.format_sql: true
hibernate.hbm2ddl.auto: create
hibernate.archive.autodetection=class, hbm
entitymanager.packagesToScan: linda

这是我测试h2的例子。您可以稍微改变一下，看看它适合您的情况。主要是您需要手动创建db表并让config.xml包含您的数据库。您可以手动创建.sql文件并创建表，如果使用spring，则让bean包含它。

someTest.java

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration("testConfig.xml") // <-- this xml you need to include
public class PortDaoImplTest {

    private static final Logger log = Logger.getLogger(sysInfoDaoImplTest.class);

    @Autowired
    private sysInfoDaoImpl sysDao;

    @After
    public void tearDown(){
        portDao = null;
    }

    @Test
    public void testGetPort() {
        log.info("Testing getInfo(String id)...");
        SysInfo p = sysDao.getInfo("nysdin2039");
        assertNotNull(p);
    }

testConfig.xml

...xml header...                    

            <!--    h2 driver -->
        <bean id="test.dataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource" lazy-init="false" >
            <property name="driverClassName" value="org.h2.Driver" />
            <property name="url" value="jdbc:h2:mem:test_mem;DB_CLOSE_DELAY=-1;MODE=ORACLE" />
        </bean>

        <!--    datasource file -->
        <jdbc:initialize-database data-source="test.dataSource">
            <!--        table list -->
            <jdbc:script location="com/yourPath/h2/schema.sql" />
            <jdbc:script location="com/yourPath/h2/test_data.sql" />

        </jdbc:initialize-database>

        <!--    bean def -->
        <bean id="sysInfoDao" class="com.mycompanyName.sysInfoDaoImpl" >
            <property name="log" ref="test.log" />
            <property name="dataSource" ref="test.dataSource" />
        </bean>

....

h2 schema.sql文件

drop table IF EXISTS tbl_all_orders;
CREATE TABLE tbl_all_orders
(
  your_stuff_ID     NUMBER               NOT NULL,
  your_other_column_stuff                VARCHAR2(15)    DEFAULT 
);

...相应地添加约束或列......

test_data.sql文件

INSERT into tbl_all_orders
   (your_column_names... , your_other_column_names...)
VALUES
   (1, 'values',...);

这是我的测试工作配置（src / test / resources文件夹中的database.properties）

# DB properties
db.driver=org.h2.Driver
db.url=jdbc:h2:mem:test;DB_CLOSE_DELAY=-1
db.username=sa
db.password=

# Hibernate Configuration
hibernate.dialect=org.hibernate.dialect.H2Dialect
hibernate.show_sql=true

# validate: validate the schema, makes no changes to the database.
# update: update the schema.
# create: creates the schema, destroying previous data.
# create-drop: drop the schema at the end of the session.
hibernate.hbm2ddl.auto=create
entitymanager.packages.to.scan=abcde

顺便说一句，你的单元测试不应该在数据库上。

从hibernate实体生成数据库
