Question

我有一个带有后续子模块的多模块maven项目

Tracker
|--Tracker-core
|--Tracker-dao
|  |---src/main/resource/spring-dao-config.xml
|
|--Tracker-services
|  |---src/main/resource/spring-service-config.xml
|
|--Tracker-web

在Tracker-dao中，我在资源包中有一个spring-context.xml。这会扫描dao类并包含其他数据源配置。

弹簧-DAO-config.xml中：

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:context="http://www.springframework.org/schema/context"
    xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd
        http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.1.xsd">

    <context:component-scan base-package="com.gits.tracker"></context:component-scan>

    <bean
        class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
        <property name="location" value="classpath:/database.properties" />
    </bean>

    <import resource="classpath:hibernate-config.xml" />

    <!-- Declare a datasource that has pooling capabilities -->

    <bean id="transactionManager"
        class="org.springframework.orm.hibernate4.HibernateTransactionManager">
        <property name="sessionFactory" ref="sessionFactory" />
    </bean>


    <bean id="hibernateTemplate" class="org.springframework.orm.hibernate4.HibernateTemplate">
        <property name="sessionFactory" ref="sessionFactory" />
    </bean>

    <!-- An AnnotationSessionFactoryBean for loading Hibernate mappings from 
        annotated domain classes. -->
    <bean id="sessionFactory"
        class="org.springframework.orm.hibernate4.LocalSessionFactoryBean">
        <property name="dataSource" ref="dataSource" />
        <property name="annotatedClasses">
            <list>
                <value>com.gits.tracker.core.entity.Address</value>
                <value>com.gits.tracker.core.entity.Company</value>
                <value>com.gits.tracker.core.entity.Customer</value>
                <value>com.gits.tracker.core.entity.User</value>
            </list>
        </property>
        <property name="hibernateProperties">
            <props>
                <prop key="hibernate.dialect">${hibernate.dialect}</prop>
                <prop key="hibernate.show_sql">true</prop>
                <prop key="hibernate.hbm2ddl.auto">update</prop>
                <!-- <prop key="hibernate.query.factory_class">org.hibernate.hql.internal.classic.ClassicQueryTranslatorFactory</prop> -->
            </props>
        </property>
    </bean>    

</beans>

单独使用dao图层的Junit测试工作正常。

在Tracker服务中，我将此Tracker核心用作依赖项。在Tracker服务中运行Junit时，它会出错，说无法加载应用程序上下文，无法找到与该名称匹配的至少1个bean。

弹簧服务-config.xml中

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xmlns:context="http://www.springframework.org/schema/context"
    xmlns:aop="http://www.springframework.org/schema/aop"
    xsi:schemaLocation="http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-3.2.xsd

        http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.1.xsd">

    <!-- <import resource="classpath:spring-dao-config.xml"/> -->
    <context:component-scan base-package="com.gits.tracker.service.services"></context:component-scan>
</beans>

Junit in Tracker-service

问题在这里：的 @RunWith（SpringJUnit4ClassRunner.class）来 @ContextConfiguration（locations = {“classpath：spring-service-config.xml”}）

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations = { "classpath:spring-service-config.xml" })
public class TestUserService extends
        AbstractTransactionalJUnit4SpringContextTests {

    private static Logger logger;
    private static ApplicationContext ctx;
    private UserService userService;

    @BeforeClass
    public static void init() {
        logger = Logger.getLogger(User.class);
        if (logger.isDebugEnabled()) {
            logger.debug("IN DEBUG MODE");
        }
    }

    @Before
    public void localInit() {
        logger.info("*************EXECUTING LOCALINIT*************");
        ctx = new FileSystemXmlApplicationContext(
                "src/main/resources/spring-config.xml");
        userService = (UserService) ctx.getBean("userServiceImpl");

        // userDao.executeQuery("delete from User where id<>3");
        logger.info("*************DELETED ALL COMPANY FROM TABLE*************");
        logger.info("*************EXITING OUT OF LOCALINIT*************");
    }

    @AfterClass
    public static void stop() {
        logger.debug("TEST COMPLETED");
    }

    private UserServiceImpl loadUserService() {
        return (UserServiceImpl) ctx.getBean("userServiceImpl");
    }

    private UserDTO createTestUserDTO() {
        UserDTO dto = new UserDTO("manoj", "manojpass", "true");
        return dto;
    }

    @Test
    public void testCreateUser() {
        loadUserService();
        UserDTO dto = createTestUserDTO();
        Long id = userService.createUser(dto);
        dto.setId(id);
        UserDTO dto_1 = userService.getUserById(id);
        org.junit.Assert.assertEquals(dto.toString(), dto_1.toString());
    }    


    @Test
    public void findByCriteriaWithAlias() {
        loadUserService();
        UserDTO dto = createTestUserDTO();
        Long id = userService.createUser(dto);
        CriteriaWithAlias criteriaWithAlias = new CriteriaWithAlias();
        HashMap<String, String> alias = new HashMap<String, String>();
        List<Criterion> criterions = new ArrayList<Criterion>();
        Criterion criterion0 = Restrictions.eq("username", dto.getUsername());
        criterions.add(criterion0);
        criteriaWithAlias.setAlias(alias);
        criteriaWithAlias.setCriterions(criterions);

List<UserDTO> users = userService
                .findByCriteriaWithAlias(criteriaWithAlias);
for (UserDTO user : users) {
org.junit.Assert.assertFalse(user.getPassword().isEmpty());
org.junit.Assert.assertFalse(user.getId().toString().isEmpty());
org.junit.Assert.assertFalse(user.getUsername().isEmpty());
org.junit.Assert.assertFalse(user.getEnabled().isEmpty());
}
}

    @Test
    public void findByProjection() {
            loadUserService();
    UserDTO dto = createTestUserDTO();
    userService.createUser(dto);
    CriteriaWithAlias criteriaWithAlias = new CriteriaWithAlias();
    HashMap<String, String> alias = new HashMap<String, String>();
    HashMap<String, String> projections = new HashMap<String, String>();
    List<Criterion> criterions = new ArrayList<Criterion>();
    projections.put("username", "username");
    projections.put("enabled", "enabled");
    Criterion criterion0 = Restrictions.ne("username", "syed");
    Criterion criterion1 = Restrictions.eq("enabled", "true");
    criterions.add(criterion0);
    criterions.add(criterion1);
    criteriaWithAlias.setAlias(alias);
    criteriaWithAlias.setCriterions(criterions);
    criteriaWithAlias.setProjections(projections);

    List<UserDTO> users = userService
            .findByCriterionWithProjection(criteriaWithAlias);
    for (UserDTO user : users) {
        org.junit.Assert.assertNull(user.getPassword());
        org.junit.Assert.assertNull(user.getId());
        org.junit.Assert.assertFalse(user.getUsername().isEmpty());
        org.junit.Assert.assertFalse(user.getEnabled().isEmpty());
    }

}

我还尝试在tracker-service模块的spring-service-config中导入tracker-core的spring-dao-config。但是，那个时候，它没有找到spring-dao-config.xml文件。

请让我知道什么是错的，我错过了什么，并建议解决方案。我已经在自己的POM.xml中添加了每个模块的依赖项，而不是在父POM.xml中添加了所有依赖项

Answer 1

我找到了解决自己问题的方法。如果我错了，请纠正我。通过从另一个maven模块访问配置文件，无法执行JUnit测试。 JUnit仅用于单元测试。而不是集成测试。

依赖的maven模块配置文件在您要测试的实际maven模块的类路径中不可用。所以，我所做的是，将依赖maven模块的配置文件复制到我需要测试的实际maven模块的类路径中。这可能不是正确的做法。但是，我能够成功执行JUnit测试。

在这种情况下执行Junit测试的其他方法是使用MOCKITO等工具：https://code.google.com/p/mockito/
