spring+hibernate中dao层的测试问题...

BaseDAOTestCase.java类片段
static {
      
        String[] paths = {"classpath*:WEB-INF/applicationContext-hibernate.xml"};
        ctx = new ClassPathXmlApplicationContext(paths); 
        if(ctx == null){
        System.out.println("ctx is null");
        }
        else{
        System.out.println("ctx is not null");
        }
       
        System.out.print(ctx.getBean("agreementDAO").toString());    
   
    }

applicationContext-hibernate.xml文件片段

你这个代码有什么用？ctx是new出来的，可能为null么？

ctx = new ClassPathXmlApplicationContext(paths);
if(ctx == null){
System.out.println("ctx is null");
}
else{
System.out.println("ctx is not null");
}

可为什么找不到bean呢？

既然你检查ctx建立是否正确的代码是错的，
那么就有理由怀疑ctx不正确
你打开spring的log看看

楼上说的spring的log在哪里?
我改了代码:
BaseDAOTestCase .java
public abstract class BaseDAOTestCase extends TestCase {
    protected final Log log = LogFactory.getLog(getClass());
    protected final static ApplicationContext ctx;
    protected ResourceBundle rb;
    
    static {
      
        String[] paths = {"classpath*:WEB-INF/applicationContext-hibernate.xml"};
        ctx = new ClassPathXmlApplicationContext(paths);
    }

AgreementDAOTest.java
public class AgreementDAOTest extends  BaseDAOTestCase{

private IAgreementDAO dao = null;  
    private List agreementList = null;
    private TagentProductPara agentProductPara = null;
 
    protected void setUp() throws Exception {
        super.setUp();    
        dao = (IAgreementDAO) ctx.getBean("agreementDAO");
           
    }
applicationContext-hibernate.xml
<!-- DAO object: Hibernate implementation -->
<bean id="agreementDAO" class="com.pms.service.dao.hibernate.AgreementHibernateDAO">
<property name="sessionFactory"><ref local="mySessionFactory"/></property>
</bean>

运行junit测试 AgreementDAOTest.java

进入了junit的届面,错误提示如下:

配置log4j

配置文件放在 WEB-INF目录下，测试时要写绝对路径，不然找不到的，呵呵！
