Java 使用JSP Hibernate登录

我在使用Hibernate进行登录时遇到问题。所有代码在语法方面都是完全正确的。NetBeans告诉我我的代码没有问题。然而，当我运行web并测试登录过程时，它不会做出反应，并且地址会在doLogin上被阻塞

所有类都已正确映射。 这就是我的问题：当我试图检索数据时，我的代码在一行上被阻塞了

在doLogin servlet上（我使用NetBeans提供的模板，并在try上填写我的代码。以下简要说明：

Connect con = new Connect(); //my code is stucked on this line.
//I've done testing where's the cause of the stuck, and this line is the cause.
List logger = con.getLogin(username, password);

并明确指出：

Connect.java

public class Connect {
    Session sesi;

        public Connect() {
            sesi = HibernateUtil.getSessionFactory().openSession();
        }



        public List getLogin(String username, String password){
            return sesi.createQuery("from MsUser WHERE username = '"+username+"' and password = '"+password+"'").list();
        }

    }

由于该查询是HQL，下面是MsUser类：

public class MsUser {

    public MsUser() {
    }

    private int userID;
    private String username;
    private String firstname;
    private String lastname;
    private String email;
    private String password;
    private String gender;
    private String address;
    private String phone;
    private String photo;

    public MsUser(int userID, String username, String firstname, String lastname, String email, String password, String gender, String address, String phone, String photo) {
        this.userID = userID;
        this.username = username;
        this.firstname = firstname;
        this.lastname = lastname;
        this.email = email;
        this.password = password;
        this.gender = gender;
        this.address = address;
        this.phone = phone;
        this.photo = photo;
    }

    public String getAddress() {
        return address;
    }

    public void setAddress(String address) {
        this.address = address;
    }

    public String getEmail() {
        return email;
    }

    public void setEmail(String email) {
        this.email = email;
    }

    public String getFirstname() {
        return firstname;
    }

    public void setFirstname(String firstname) {
        this.firstname = firstname;
    }

    public String getGender() {
        return gender;
    }

    public void setGender(String gender) {
        this.gender = gender;
    }

    public String getLastname() {
        return lastname;
    }

    public void setLastname(String lastname) {
        this.lastname = lastname;
    }

    public String getPassword() {
        return password;
    }

    public void setPassword(String password) {
        this.password = password;
    }

    public String getPhone() {
        return phone;
    }

    public void setPhone(String phone) {
        this.phone = phone;
    }

    public String getPhoto() {
        return photo;
    }

    public void setPhoto(String photo) {
        this.photo = photo;
    }

    public int getUserID() {
        return userID;
    }

    public void setUserID(int userID) {
        this.userID = userID;
    }

    public String getUsername() {
        return username;
    }

    public void setUsername(String username) {
        this.username = username;
    }


}

请帮忙。但我怀疑Connect的构造器是主要原因。任何人都可以建议、修复或告诉我是什么原因导致了这种情况

您可以在hibernateUtil.java文件中尝试以下代码：

SessionFactory factory = new Configuration().configure().buildSessionFactory();
        session = factory.openSession();
        String query = "select reg.username,reg.password from MsUser as reg where reg.username='" + username + "' and reg.password='" + password + "'";
        Query DBquery = session.createQuery(query);
        for (Iterator it = DBquery.iterate(); it.hasNext();) {            it.next();
            count++;
        }
        System.out.println("Total rows: " + count);
        if (count == 1) {
            return true;
        } else {
            return false;
        }
    }

代码没有理由卡在您所说的位置，请检查行

new Connect（）

中是否有断点您是否正确配置了数据库？没有stacktrace错误？不应该在那里阻塞…是的，我已检查了所有断点。也许其他人可以帮上忙？谢谢。。。
