本文介绍了一个具体的web.xml配置示例，包括过滤器、监听器、servlet等元素的定义，并展示如何通过Spring框架进行单元测试，利用Spring的上下文加载及Hibernate会话管理。

web.xml配置如下：

如果要在TestCase里测试用例的话，则用创建如下类：

public abstract class AbstractTestBean extends TestCase {

    protected ApplicationContext applicationContext;

    private SessionFactory sessionFactory;

    private Session session;

    protected void setUp() throws Exception {
        String configFile = "applicationContext.xml"; // spring/*.xml
        applicationContext = new ClassPathXmlApplicationContext(configFile);
        sessionFactory = (SessionFactory) applicationContext.getBean("sessionFactory");
        session = SessionFactoryUtils.getSession(sessionFactory, true);
        session.setFlushMode(FlushMode.NEVER);
        TransactionSynchronizationManager.bindResource(sessionFactory, new SessionHolder(session));
    }

    protected void tearDown() throws Exception {
        TransactionSynchronizationManager.unbindResource(sessionFactory);
        SessionFactoryUtils.releaseSession(session, sessionFactory);
    }
}

然后再将自己的类继承自上类即可，如：

public class TestDB extends AbstractTestBean{
    public void test1() {
        ApplicationContext ctx = new ClassPathXmlApplicationContext(
                "applicationContext.xml");
        BuginfoDAO buginfoDAO = (BuginfoDAO) ctx.getBean("BuginfoDAO");
        BugtypeinfoDAO bugtypeinfoDAO = (BugtypeinfoDAO) ctx
                .getBean("BugtypeinfoDAO");
        Bugtypeinfo bugtype = bugtypeinfoDAO.findById(new Long(3502));
        Buginfo buginfo = new Buginfo();
        buginfo.setBugtypeinfo(bugtype);
        buginfo.setSvTitle("title");
        buginfoDAO.save(buginfo);
    }
}
