spring-test环境搭建

1,我的目录结构

2，test/resource/spring-context.xml 与 src/resource/spring-context.xml  相同

    包括：扫描包、声明事务等

        <property name="packagesToScan">

    <!-- 将事务与Hibernate关联 -->
    <bean id="transactionManager" class="org.springframework.orm.hibernate3.HibernateTransactionManager">
        <property name="sessionFactory">
            <ref local="sessionFactory"/>

<!--     事务（注解 ） -->
<!--     <tx:annotation-driven transaction-manager="transactionManager" proxy-target-class="true"/> -->
    <tx:advice id="txAdvice" 
    	transaction-manager="transactionManager">
        <tx:attributes>
        	<tx:method name="*"/>
        </tx:attributes>
    </tx:advice>
    <aop:config>
    	<aop:pointcut expression="execution(* com.xxx.dao.impl.*Impl.*(..))"  id="myPointcut"/>
    	<aop:advisor advice-ref="txAdvice"
             pointcut-ref="myPointcut"/>
    </aop:config>
</beans>  

 注意：若session的建立（不知道改怎么说）在service层，且你只想测试dao层，请将上面标红的地方配置正确。test中的包结构要与src中的一致，若不一致请执行配置test下的spring-context.xml 。

否则会报：org.hibernate.HibernateException: No Hibernate Session bound to thread, and configuration does not allow creation of non-transactional one here

3，UserDaoTest.java

 

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations ={"classpath*:resource/spring-context.xml"})// 加载spring配置文件路径  
public class UserDaoTest {
	
	@Autowired
	private IUserDao userDao;
	
	@Test
	public void getUserById_Test(){
		System.out.println(userDao);
		User user = userDao.getUserById(1);
		System.out.println(user.getUserName());
	}
}

 加载的resource/spring-context.xml 是test下的。

@RunWith(SpringJUnit4ClassRunner.class) 一定要有。

4，spring-test方便我们对项目进行单元测试，而不必启动项目
