JSF 1.2在JSP页面中根本不工作

标签： java spring jsp jsf spring-boot

我正在研究一个旧项目，试图让它与Jetty，Spring＆amp; Spring Boot，它使用了我并不熟悉的JSF 1.2。它还有我想要摆脱的ibm taglib库，但我认为问题是我错过了库的一部分所以我暂时将它们添加到项目中。

我遇到了主要问题，当我将用户凭据（登录和密码）填充到页面时，控制器由于某种原因将它们作为空值接收。感觉实际上我的登录页面中的所有＃{}都没有注册到JSF。

确切的错误是

  

javax.faces.FacesException：＃   {aaController.login}：java.lang.NullPointerException

对于依赖部分，我有jsf-api的jsf-api，jsf-impl，jsf-ibm，odc-jsf。

我的web.xml看起来像这样：

我的控制器如下所示： 

public class AaController extends BaseController {
public static final int ROLE_INTERNAL = 1;
public static final int ROLE_EXTERNAL = 2;

private loginView loginView = new loginView();
private int role;

public String login() throws OrgHallintaException {
    String result = null;
    AaFasadi aaFasadi = new AaFasadi();
    log.info("Loggin in");


    if (aaFasadi.login(loginView.getLogin(), loginView.getPassword())) {

        if (aaFasadi.getEnviroment().trim().equals("PRODUCTION")) {
            loginView.setEnviroment("        ");
        } else {
            loginView.setEnviroment(aaFasadi.getEnviroment());
        }
        result = "ok";

    } else {
        result = "error";
    }

    return result;
}

public String logout() {
    AaFasadi aaFasadi = new AaFasadi();
    aaFasadi.logout();
    return "ok";
}

public loginView getloginView() {
    return loginView;
}

public Kayttaja getUser() {
    return AaFasadi.getUser();
}

}

Controller调用的类看起来像这样 

public class AaFasadi {

private String enviroment="";

private static final String USER_SESSION_KEY = "orgmanager.User";

public static User getUser() {
    ServletRequest req = (ServletRequest) FacesContext.getCurrentInstance().getExternalContext().getRequest();                     
    return getUser(req);
}

public static User getUser(ServletRequest req) {        
    HttpServletRequest request = (HttpServletRequest) req;

    User user = (User) request.getSession(true).getAttribute(USER_SESSION_KEY);

    return user;

}

public boolean login(String LoginName, String password) throws OrgHallintaException {

    User user = null;

    try {           
            PersonelLoginTask personelLoginTask = new PersonelLoginTask();
            PersonelLoginView personelLoginView = toimihenkiloSisaankirjausTehtava.execute(LoginName.toUpperCase(), password);

        if (personelLoginView != null) {
            if (personelLoginView.getEnviroment().trim().equals("PRODUCTION"))
                personelLoginView.setEnviroment("        ");
            User = new DefaultUserImpl(personelLoginView);
            Enviroment = personelLoginView.getEnviroment();
            }

    } catch (TehtavanHallintaException e) {
        System.out.println("User " + Usertunnus + " Login failed " + e);
    }


    if (User != null) {

        ServletRequest req = (ServletRequest) FacesContext.getCurrentInstance().getExternalContext().getRequest();                     
        HttpServletRequest request = (HttpServletRequest) req;        
        request.getSession(true).setAttribute(User_SESSION_KEY, User);

        return true;
    } else {
        return false;
    }
}

public void logout() {
    ServletRequest req = (ServletRequest) FacesContext.getCurrentInstance().getExternalContext().getRequest();                     
    HttpServletRequest request = (HttpServletRequest) req;        
    request.getSession(true).removeAttribute(User_SESSION_KEY);
    request.getSession().invalidate();               
}



public String getEnviroment() {
    return enviroment;
}

public void setEnviroment(String ymparisto) {
    this.enviroment = enviroment;
}

}

出于某种原因，我的Login.jsp页面aaController.loginView.login＆amp; aaController.loginView.password根本不起作用，它们返回空值，我不知道为什么。 loginView在其类中具有正确的Get和Set方法。我的JSF配置有问题吗？

我的loginview看起来像这样 

public class loginView extends BaseView {

private String login;
private String password;
private String Enviroment;
private Date date = new Date(System.currentTimeMillis());




public String getlogin() {
    return login;
}
public void setlogin(String login) {
    this.login = login;
}
public String getpassword() {
    return password;
}
public void setpassword(String password) {
    this.password = password;
}

public String getEnviroment() {
    return Enviroment;
}

public void setEnviroment(String Enviroment) {
    this.Enviroment = Enviroment;
}


public void setDate(Date date) {
    this.date = date;
}

}

答案 0 :(得分：0)

好的答案很傻，但我终于找到了答案。我使用的是web.xml架构版本2.4，但它需要2.5才能工作。
