昨天想整合下springmvc和mybatis，用junit写了个测试，测试过程中，mybatis的mapper无法注入，报BeanCreationException，相关信息大家看下，帮小弟解决下

1 错误堆栈信息

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'com.hft.dal.mapper.AccountMapperTest': Injection of autowired dependencies failed; nested exception is org.springframework.beans.factory.BeanCreationException: Could not autowire field: private com.hft.dal.mapper.AccountMapper com.hft.dal.mapper.AccountMapperTest.accountMapper; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No matching bean of type [com.hft.dal.mapper.AccountMapper] found for dependency: expected at least 1 bean which qualifies as autowire candidate for this dependency. Dependency annotations: {@org.springframework.beans.factory.annotation.Autowired(required=true)}

2 applicationContext.xml

    <context:component-scan base-package="com.hft" />
    <context:annotation-config />
    <tx:annotation-driven />
    <bean id="dataSource"
        class="org.springframework.jdbc.datasource.DriverManagerDataSource"
        destroy-method="close">
        <property name="driverClassName" value="com.mysql.jdbc.Driver" />
        <property name="url" value="jdbc:mysql://127.0.0.1:3306/test" />
        <property name="username" value="root" />
        <property name="password" value="root" />
    </bean>
    <bean id="transactionManager"
        class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
        <property name="dataSource" ref="dataSource" />
    </bean>
    <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
        <property name="dataSource" ref="dataSource" />
        <property name="mapperLocations">
            <list>
                <value>classpath*:com/hft/dal/mapper/*Mapper.xml</value>
            </list>
        </property>
    </bean>
    <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
        <property name="basePackage" value="com.hft.dal.mapper" />
        <property name="markerInterface" value="com.hft.dal.mapper.MarkerInterfaceMapper" />
    </bean>

3 AccountMapper类，MarkerInterfaceMapper是个空接口

public interface AccountMapper extends MarkerInterfaceMapper {
public List<Account> getAllAccount();
public void addAccount(Account account);
}

4 junittest类

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations={"classpath*:applicationContext.xml"})
public class AccountMapperTest extends AbstractJUnit4SpringContextTests{
    @Autowired
    private AccountMapper accountMapper;
    @Test
    public void testGetAllAccount() {
        System.out.println(accountMapper.getAllAccount().size());
}

5 所引入的的包

6 项目目录结构

Junit4.11进行单元测试报initialization Error错误
