我的托管豆有问题。我无法设法在它们之间传递参数。这是一个 XHTML 片段。它基本上是一个登录表单。它只是将参数发送到后台bean。
<h:outputLabel for="username" value="Kullanıcı Adı: *" />
<p:inputText id="username" value="#{loginBean.username}" required="true" requiredMessage="Kullanıcı adı giriniz.">
<f:validateLength minimum="2" />
</p:inputText>
<p:message for="username" display="icon"/>
<h:outputLabel for="password" value="Şifre: *" />
<p:inputText id="password" value="#{loginBean.password}" required="true" requiredMessage="Şifreyi giriniz!" type="password">
<f:validateLength minimum="2" />
</p:inputText>
<p:message for="password" id="msgPass" display="icon"/>
<f:facet name="footer">
<center>
<p:commandButton id="submit" value="Giriş" icon="ui-icon-check" action="#{loginBean.check}" style="margin:0" update="grid"/>
</center>
</f:facet>
在我的支持 bean 中,我正在检查用户输入是否与数据库记录匹配。如果是,那我让他进入系统。同时,我要取他的全名。
我的豆豆:
@ManagedBean
@RequestScoped
public class LoginBean {
public String getUsername() {
return username;
}
public void setUsername(String username) {
this.username = username;
}
public String getPassword() {
return password;
}
public void setPassword(String password) {
this.password = password;
}
public String getMgs() {
return mgs;
}
public void setMgs(String mgs) {
this.mgs = mgs;
}
public String getFullname() {
return fullname;
}
public void setFullname(String fullname) {
this.fullname = fullname;
}
public String getOriginalURL() {
return originalURL;
}
public void setOriginalURL(String originalURL) {
this.originalURL = originalURL;
}
private String username;
private String password;
private String mgs;
private String fullname;
private String originalURL;
private static Logger log = Logger.getLogger(LoginBean.class.getName());
public String check() throws Exception {
Connection con = DriverManager.getConnection("jdbc:mysql://localhost:3306/projetakip", "root", "");
Statement stmt = con.createStatement();
String md5Pass = md5(password);
String SQL = "select * from users where username='" + username + "' and password='" + md5Pass + "'";
ResultSet rs = stmt.executeQuery(SQL);
while (rs.next()) {
if (username.matches(rs.getString("username")) && md5Pass.matches(rs.getString("password"))) {
this.fullname = rs.getString("ad") + " " + rs.getString("soyad");
return "panel?faces-redirect=true";
} else {
FacesMessage msg = new FacesMessage("Yanlış kullanıcı adı/şifre.");
FacesContext.getCurrentInstance().addMessage(null, msg);
return "index?faces-redirect=true";
}
}
return "index?faces-redirect=true";
}
public void getProductSetupData(ActionEvent event) {
FacesContext context = FacesContext.getCurrentInstance();
Data data = context.getApplication().evaluateExpressionGet(context, "#{data}", Data.class);
}
我想要的是传递fullName
给其他bean(或页面)。如何在我的 bean 之间传递这个变量?
提前致谢。
