测试类action

@ParentPackage("basePackage")
@Namespace("/")
@Action(value = "testAction")
@Controller
public class TestAction {
    private static final Logger logger = Logger.getLogger(TestAction.class);

    public void test() {
        logger.info("进入action");
        ApplicationContext ac = WebApplicationContextUtils.getWebApplicationContext(ServletActionContext.getServletContext());
        if (ac == null) {
            logger.info("ac为空");
        }
        logger.info("ac不为空");
        TestServiceI userservicei = (TestServiceI) ac.getBean("testServiceImpl");
        if(userservicei==null)
        {
            logger.info("userservicei为空");
        }
        userservicei.test();

    }

}

service


@Service("testServiceImpl")
public class TestServiceImpl implements TestServiceI {
    private static final Logger logger = Logger.getLogger(TestServiceImpl.class);

    @Override
    public void test() {
        logger.info("进入TestServiceImpl");
    }

}

已经中junit中测试能找到service，但在web环境中不能找到bean

public class TestSpring {
    @Test
    public void test() {
        ApplicationContext ac = new ClassPathXmlApplicationContext(new String[] { "classpath:spring.xml","classpath:spring-hibernate.xml" });
        TestServiceI userservicei = (TestServiceI) ac.getBean("testServiceImpl");
        userservicei.test();
    }
}

环境和JDK不兼容，引入别人的环境就解决了

不懂原因，可是正常情况下struts不也是要交给spring代理吗？
