在Jboss 7.1.1 final中部署我的Web应用程序时遇到问题。 虽然部署它给了我很多警告，如下 -

但最终战争已经部署，我能够在Jboss 7.1.1决赛中打开网址。但是当我尝试登录应用程序时，它会出现以下错误。

相同的项目在Tomcat 7中运行得很好。

代码段 - ＆gt; 

@Action(TNIBeans.AUTHORIZATION_ACTION)
@Scope(TNIBeans.BEAN_SCOPE)
public class AuthorizationAction extends ActionSupport implements SessionAware,ServletRequestAware {

    private InputStream inputStream;
    /**

     */
    private static final Logger logger = Logger
            .getLogger(AuthorizationAction.class);
    @Autowired

    private Map<String, Object> session = null;
    private Employee emp = null;

    private String userName;

    // It couldn't create instance of "employeeServiceImpl" interface defined above..... 

            emp = employeeServiceImpl.authorize(userName);

@Override

        System.out.println("Hi Tapo..."+signum); // this is not printed in console output if u observe (ie, controller doesn't                                  enter authorize function)

                emp.setRoles(Role.LnCD_ADMIN);

            return emp;
        }catch(BusinessException e){
            throw new BusinessException(e.getMessage());
        }catch(Exception e){

2 个答案:

答案 0 :(得分：2)

这些警告仅在devMode（= true）期间可用，如果您不使用Convention插件，一切都应该没问题。

从Struts 2的2.3.1版开始，添加了对JBoss 7的适当支持。

答案 1 :(得分：0)

根据与您的部署文件夹中的jboss server.log文件相关的控制台输出，您在java.lang.NullPointerException的{​​{1}}方法中获得了login 。并且在声明

中发生了异常 
AuthorizationAction

emp = employeeServiceImpl.authorize(userName); 即employeeServiceImpl。如果它不是null，那么我们在日志中看到了null。没有类似的事发生。

然后"Hi Tapo..."是通过Spring应用程序上下文初始化的属性。即使不是你在这里发布了employeeServiceImpl我也假设其中有bean定义。然后它应该注入，再次假设这也有效，因为你说它在Tomcat服务器上运行良好。

因此，只有在bean创建失败时才会发生这种情况。这就是aplicationContext.xml你不应该阻止的情况。

那一刻我们只知道NullPointerException bean失败了。我们没有消息来源。你没有发布它。然后我们需要日志文件中的其他异常来查找未创建bean的原因。没得到它。

因此，找到在JBoss 7上的Tomcat 7中部署工作应用程序的唯一方法。发生的事情是，一些集成框架的行为与预期的略有不同。并且它们变成了加载Tomcat下未使用的额外库。这是因为Tomcat中没有JBoss的功能。最后我发现我的资源停止加载，因为JBoss返回带有employeeService协议的URL。甚至我的应用程序都了解vsf协议，我需要添加这些协议以使其正常工作。
