问题
I have to execute Unit test on one of my Dao classes using Spring. Here is my unit test:
@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);
}
}
And My bean configuration files:
app-config.xml:
<?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>
Where BeanConfiguration-production.xml is same as above except for <beans profile="production" ... in it.
When I simply execute a maven test doing mvn test it fails throwing the following exception:
java.lang.IllegalStateException: Could not load TestContextBootstrapper [class org.springframework.test.context.support.DefaultTestContextBootstrapper]. Specify @BootstrapWith's 'value' attribute or make the default bootstrapper class available.

It looks like I am missing a dependency or something, because the stacktrace contains Caused by: java.lang.NoSuchMethodError: org.springframework.beans.BeanUtils.instantiateClass.
Here is the Spring's dependency list in my pom.xml:
...
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring</artifactId>
<version>2.5.6</version>
</dependency>
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-test</artifactId>
<version>4.1.4.RELEASE</version>
</dependency>
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-context</artifactId>
<version>4.1.4.RELEASE</version>
</dependency>
<dependency>
<groupId>junit</groupId>
<artifactId>junit</artifactId>
<version>4.11</version>
</dependency>
...
回答1:
It is probably a version conflict since you are using a old version of base spring (2.5.6) with very new one (4.1.4.RELEASE) for your test en context includes
回答2:
In my case it was a version conflict caused by activemq-all. That dependency (5.12.2 in my case) includes an incompatible version of spring (I just upgraded to spring 4.3.4). So, save yourself a few hours of debugging and check not only the Dependency Hierarchy in your favorite IDE, but also look inside those jar files to see if any are embedding org.springframework packages.
