Question

我必须使用Spring在我的一个Dao类上执行单元测试。这是我的单元测试：

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations={"classpath:app-config.xml"})
@ActiveProfiles("local")
public class HouseDaoTest {

    @Autowired
    HouseDataDao houseDataDao;

    @Test
    public void saveTest(){
        HouseData data = new HouseData();
        Address add = new Address();
        // Truncating for sake of simplicity
        houseDataDao.save(data);
    }
}

我的bean配置文件：

应用-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"
    xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd">
    <import resource="BeanConfiguration-localhost.xml"/>
    <import resource="BeanConfiguration-production.xml"/>
</beans>

BeanConfiguration-localhost.xml：

<?xml version="1.0" encoding="UTF-8"?>
<beans profile="local" 
    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:tx="http://www.springframework.org/schema/tx"
    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-2.5.xsd
        http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-2.5.xsd">
    <context:annotation-config />
    <tx:annotation-driven />
    <bean id="dataSource"
        class="org.springframework.jdbc.datasource.DriverManagerDataSource">
        <property name="driverClassName" value="com.mysql.jdbc.Driver" />
        <property name="url" value="jdbc:mysql://localhost:3306/dbtest" />
        <property name="username" value="root" />
        <property name="password" value="" />
    </bean>
    <bean id="sessionFactory"
        class="org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean">
        <!-- Tuncated for sake of simplicity -->
    </bean>
    <bean id="transactionManager"
        class="org.springframework.orm.hibernate3.HibernateTransactionManager">
        <property name="sessionFactory" ref="sessionFactory" />
    </bean>
    <!-- Project Specific Beans -->
    <bean id="HouseDataDao" class="com.datasaver.dao.HouseDataDaoImpl"></bean>
</beans>

其中BeanConfiguration-production.xml与上面的内容相同，但<beans profile="production" ...除外。

当我只是执行maven测试mvn test时，它无法抛出以下异常：

    ... 25 more

看起来我缺少一个依赖项或其他东西，因为stacktrace包含Caused by: java.lang.NoSuchMethodError: org.springframework.beans.BeanUtils.instantiateClass。

以下是pom.xml中的Spring依赖列表：

        <groupId>org.springframework</groupId>

Answer 1

这可能是版本冲突，因为您使用旧版本的基本弹簧（2.5.6）和非常新版本（4.1.4.RELEASE）用于您的测试环境包括

Answer 2

在我的情况下，这是由activemq-all引起的版本冲突。这种依赖（在我的例子中为5.12.2）包括一个不兼容的spring版本（我刚刚升级到spring 4.3.4）。因此，节省几个小时的调试时间，不仅要检查您喜欢的IDE中的依赖关系层次结构，还要查看这些jar文件，看看是否嵌入了org.springframework包。

Maarten是对的。以下是pom.xml中新的依赖项列表，它对我有用：
