用junit测试SSH项目以及常见错误解决方法

    public static BeanFactory factory = null;   
    public static UserDAOImpl userDAOImpl = null;   
    public static SessionFactory sessionFactory = null;   
    public static Session session = null;   
       
    @BeforeClass  
    public static void setUpBeforeClass() throws Exception {   
        try{   
            factory = new ClassPathXmlApplicationContext("spring/*.xml");   
            sessionFactory = (SessionFactory) factory.getBean("sessionFactory");   
            session = sessionFactory.openSession();   
            TransactionSynchronizationManager.bindResource(sessionFactory, new SessionHolder(session));   
            userDAOImpl = (UserDAOImpl) factory.getBean("userDAO");   
        }catch(Exception e){   
            e.printStackTrace();   
        }   
    }

1.读取配置文件,根据项目具体情况更改文件位置

2.获取sessionFactory

3.使用spring提供的org.springframework.transaction.support.TransactionSynchronizationManager来代替org.springframework.orm.hibernate3.support.OpenSessionInViewFilter, 否则遇到懒加载会出错

4.开始测试吧:）

PS:如果不加try...catch,初始化异常不会显示,开始因为找不到哪错了浪费很多时间%>_<%

 

 

附上本人遇到的错误的解决方法:

1.No Hibernate Session bound to thread, and configuration does not allow creation of non-transactional one here错误:

事务配置不对,或者加了@Transactional但没有加 <tx:annotation-driven proxy-target-class="true" transaction-manager="transactionManager" />

spring事务配置例子

    <aop:config>  
        <aop:pointcut id="txServices" expression="execution(* ssh.service.*.*.*(..))"/>  
        <aop:advisor pointcut-ref="txServices" advice-ref="txAdvice"/>  
    </aop:config>  
       
    <tx:advice id="txAdvice" transaction-manager="transactionManager">  
        <tx:attributes>  
            <tx:method name="add*"/>  
            <tx:method name="save*"/>  
            <tx:method name="delete*"/>  
            <tx:method name="update*"/>  
            <tx:method name="edit*"/>  
            <tx:method name="upload*"/>  
            <tx:method name="download*"/>  
            <tx:method name="get*" read-only="true" timeout="30"/>  
            <tx:method name="search*" read-only="true"/>  
            <tx:method name="export*" read-only="true"/>  
        </tx:attributes>  
    </tx:advice>  
       
    <!-- 支持@Transient -->  
    <!--   
    <tx:annotation-driven proxy-target-class="true" transaction-manager="transactionManager" />  
    -->  
        
    <bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">  
        <property name="dataSource" ref="dataSource"/>  
    </bean> 

2.java.lang.NoSuchMethodError: org.objectweb.asm.ClassWriter错误:

本人使用的struts2.1.8+spring2.5.6+hibernate3.6.0,使用的cglib-2.2.jar,但spring带的是asm-2.2.3.jar,换成asm-3.2.jar后问题解决
