在 JBOSS 7 中部署 Struts 2 項目

Question

我在 Jboss 7.1.1 final 中部署我的 Web 應用程序時遇到問題。 在部署它時給了我很多警告，如下所示：

但最終戰爭被部署了，我能夠在 Jboss 7.1.1 final 中打開 URL。 但是當我嘗試登錄應用程序時，它給了我以下錯誤。

相同的項目在 Tomcat 7 中運行得非常好。

代碼片段：

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

    private InputStream inputStream;
    /**
     * Logger for this class
     */
    private static final Logger logger = Logger
            .getLogger(AuthorizationAction.class);
    @Autowired
    private XStream xstream;
    
    public void logException(String message) {
        logger.error(message);
    }

    public void log(String msg) {
        logger.info(msg);
    }
    
    HttpServletRequest request = null;

    @Autowired
    @Qualifier(TNIBeans.EMPLOYEE_SERVICE_IMPL)
    private EmployeeService employeeServiceImpl;
    @Autowired
    @Qualifier(TNIBeans.CODE_SERVICE_IMPL)
    private CodeMasterService codeMasterService;
    
    Map<String,Map<String,String>> codeMaster = null;
    private String strResult = null;

    private static final long serialVersionUID = -8517227229292215672L;

    private Map<String, Object> session = null;
    private Employee emp = null;
    
    private String userName;
    private String password;
    private String roles;
    private String responseMsg;

    public String login () throws Exception {
        log("Entered login");
        if (logger.isDebugEnabled()) {
            logger.debug("execute() - start.....");
        }
        try {
            log("Authentication Started For User : "+userName);
        //  employeeServiceImpl.authenticate(userName, password);
            inputStream = new ByteArrayInputStream("success".getBytes("UTF-8"));
            log("Authentication Result : success");
            log("Initiating authorisation : ");  // This is printed in Console output if u observe (ie, till here the code                                  executed properly)

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

            emp = employeeServiceImpl.authorize(userName);

授權函數的另一個代碼片段：

@Override
    public Employee authorize(String signum) throws BusinessException {
        System.out.println("Hi Tapo..."+signum); // this is not printed in console output if u observe (ie, controller doesn't                                  enter authorize function) 
        logger.info("authorize : "+signum);
        Employee emp = null;
        try{
            emp = findRoles(signum);
            if (WebConstants.adminSignum.equalsIgnoreCase(signum)) {
                emp.setSignum(signum);
                emp.setName("System Administrator");
                emp.setRoles(Role.LnCD_ADMIN);
                emp.setRoles(Role.LnCD_DELEGATE);
                emp.setRoles(Role.SYS_ADMIN);
            }
            return emp;
        }catch(BusinessException e){
            throw new BusinessException(e.getMessage());
        }catch(Exception e){
            throw new BusinessException(e.getMessage());
        }
    }   

Answer 1

這些警告僅在 devMode(=true) 期間可用，如果您不使用 Convention 插件，一切都應該沒問題。

從 Struts 2 的 2.3.1 版開始添加了對 JBoss 7 的適當支持。

Answer 2

根據與部署文件夾中的 jboss server.log文件相關的控制台輸出，您在AuthorizationAction的方法login中有java.lang.NullPointerException 。 並且異常發生在語句中

emp = employeeServiceImpl.authorize(userName); 

也就是說， employeeServiceImpl為null 。 如果它不為null那么我們就會在日志中看到"Hi Tapo..." 。 沒有發生類似的事情。

那么employeeServiceImpl是一個通過Spring 應用程序上下文初始化的屬性。 即使您沒有在這里發布aplicationContext.xml我也假設其中有 bean 定義。 然后它應該被注入，再次假設這也有效，因為你說它在Tomcat服務器上運行良好。

因此，只有在 bean 創建失敗時才會發生這種情況。 這正是您不應該阻止的NullPointerException的情況。

那一刻我們只知道employeeService bean 失敗了。 我們沒有消息來源。 你沒有發布它。 然后我們需要日志文件中的其他異常來查找未創建 bean 的原因。 也沒收到。

因此，找出在 JBoss 7 上的 Tomcat 7 中部署工作應用程序的唯一方法。發生的事情是，一些集成框架的行為與預期略有不同。 並且它們成為加載在 Tomcat 下未使用的附加庫。 這是因為 JBoss 的功能在 Tomcat 中不可用。 最后我發現我的資源停止加載，因為 JBoss 使用vsf協議返回 URL。 甚至我的應用程序也理解vsfzip協議，我需要添加這些協議才能使其工作。
