Question

我正在尝试将dbunit和spring dbunit包含到我的项目中进行测试。我有2个文件夹： “SRC /测试/ JAVA /道” 和 “SRC /测试/资源/道”。

在资源中dao

<?xml version='1.0' encoding='UTF-8'?>
<dataset> 
<Brands id="1" brandName="Apple" /> 
</dataset>

尝试使用大写和小写（BRANDS，品牌），仍有同样的问题。

在主java中

public class BrandsDaoTest {

@Autowired
private BrandsDao brandsDao;
private Brand brand;

private static final int ID = 1;
private static final String BRANDNAME = "apple";
private static final String UBRANDNAME = "horizont";

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration({ "classpath:app-context.xml","classpath:test-context.xml" })
@TestExecutionListeners({ DependencyInjectionTestExecutionListener.class,
DbUnitTestExecutionListener.class })
@Test
@DatabaseSetup("schema.xml")
public void find(){

    Brand brand = brandsDao.find(1);
    assertNotNull(brand);
    brandsDao.delete(ID);
    assertNull(brandsDao.find(ID));

}
}

我的品牌实体：

@Entity
@Table(name = "brands")
public class Brand {

@Id
@GeneratedValue(strategy=GenerationType.AUTO)
private int id;


@Column(name="BrandName",nullable=false)
private String brandName;
@OneToMany(fetch = FetchType.LAZY)
@JoinColumn(name="BrandId",updatable=false)
private List<Device> devices;


public Brand(){

}

public Brand(int id,String brandName){
    this.id = id;
    this.brandName = brandName;
}

public int getId() {
    return id;
}
public void setId(int id) {
    this.id = id;
}


public String getBrandName() {
    return this.brandName;
}
public void setBrandName(String brandName) {
    this.brandName = brandName;
}   


public List<Device> getDevices(){
    return this.devices;
}

public void setDevices(List<Device> devices){
    this.devices = devices;
}

 public boolean equals(Object obj) {
     boolean result = false;
       if (!(obj instanceof Brand))
            return result;
       Brand brand = (Brand)obj;
       if(this.getId() == brand.getId())
           result = true;
       return result;
 }
}

这是我的联系：

bean id="dataSource" class="org.apache.commons.dbcp2.BasicDataSource" destroy-method="close">
    <property name="driverClassName" value="org.h2.Driver"/>
    <property name="url"      value="jdbc:h2:mem:dbtest;
    MODE=MySQL;DB_CLOSE_DELAY=-1;DB_CLOSE_ON_EXIT=FALSE" />

    <property name="username" value="sa"/>
    <property name="password" value=""/>
</bean> 

<bean id="sessionFactory"
    class="org.springframework.orm.hibernate4.LocalSessionFactoryBean">
    <property name="dataSource" ref="dataSource" />
    <property name="packagesToScan"
        value="com.entities" />

    <property name="hibernateProperties">
        <props>
            <prop key="dialect">org.hibernate.dialect.H2Dialect</prop>
            <prop key="connection.useUnicode">true</prop>
            <prop key="connection.characterEncoding">UTF-8</prop>
            <prop key="hibernate.hbm2ddl.auto">create-drop</prop>
        </props>
    </property>
</bean>

在使用dbunit之前，遇到了同样的问题，并且

<prop key="hibernate.hbm2ddl.auto">create-drop</prop>

为我解决了这个问题。现在，如果我的schema.xml文件为空并且我正在使用“brandsDao.create（new Brand（））”方法在其中一种测试方法中添加品牌，一切正常。但是当我添加

<Brands id="1" brandName="Apple" />

到我的schema.xml，我得到了这个“NoSuchTableException：Brands”。

此外，在我将其插入我的上下文xml：

之前

<bean id="dbUnitDatabaseConfig" class="com.github.springtestdbunit.bean.DatabaseConfigBean">
    <property name="datatypeFactory">
        <bean class="org.dbunit.ext.mysql.MySqlDataTypeFactory" />
    </property>
    <property name="caseSensitiveTableNames" value="true" />
</bean>

<bean id="dbUnitDatabaseConnection"   class="com.github.springtestdbunit.bean.
DatabaseDataSourceConnectionFactoryBean">
    <property name="dataSource" ref="dataSource" />
    <property name="databaseConfig" ref="dbUnitDatabaseConfig"/>

</bean>

我有“没有在架构null中找到表'BRANDS'”。试过不同的文章这个错误，但仍然没有任何帮助。我猜我的数据库不是在dbunit时创建的尝试从架构中插入数据。

会对一些提示或建议表示感谢。

感谢Alan Hay的回复。我已经尝试了一组hibernate属性到我的sessionFactory bean

<bean id="sessionFactory"
    class="org.springframework.orm.hibernate4.LocalSessionFactoryBean">
    <property name="dataSource" ref="dataSource" />
    <property name="packagesToScan"
        value="com.entities" />

    <property name="hibernateProperties">
        <props>
            <prop key="dialect">${hibernate.dialect}</prop>
            <prop key="connection.useUnicode">true</prop>
            <prop key="connection.characterEncoding">UTF-8</prop>
            <prop key="hibernate.hbm2ddl.auto">create</prop>
            <prop key="hibernate.show_sql">true</prop>
            <prop key="hibernate.cache.use_second_level_cache">false</prop>
            <prop key="hibernate.cache.provider_class">org.hibernate.cache.EhCacheProvider</prop>
        </props>
    </property>
</bean>

最有帮助的是

<prop key="hibernate.show_sql">true</prop>

它为我提供了我的虚拟数据库创建的完整跟踪。所有名称都在那里小写，所以改变之后

<Brands id="1" brandName="Apple" />

到

<brands id="1" brandName="Apple" /> 
<brands id="2" brandName="Apple2" />

有效。我很确定我以前尝过这个，也许我没有包含

<bean id="dbUnitDatabaseConfig" class="com.github.springtestdbunit.bean.DatabaseConfigBean">
    <property name="datatypeFactory">
        <bean class="org.dbunit.ext.mysql.MySqlDataTypeFactory" />
    </property>
    <property name="caseSensitiveTableNames" value="true" />
</bean>

那时候。然而它现在工作正常。再次感谢您的提示。

现在我的hibernate属性看起来像：

 <props>
            <prop key="dialect">org.hibernate.dialect.H2Dialect</prop>
            <prop key="connection.useUnicode">true</prop>
            <prop key="connection.characterEncoding">UTF-8</prop>
            <prop key="hibernate.hbm2ddl.auto">create</prop>
            <!--<prop key="hibernate.show_sql">true</prop> -->

        </props>
