用junit测试SSH项目以及常见异常解决办法

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-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-transaction-manager="transactionManager" />      -->              <bean id="transactionManager" 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
