我正在使用JSF 2.1和PrimeFaces 3.2，服務器Tomcat 7開發應用程序。現在，我正在爲表單註冊新用戶。問題在於轉換器。JSF轉換器在PrimeFaces表格驗證後無法工作
我使用幾個標準字段，其中兩個是密碼。我有自定義數據類型的密碼，所以我想使用轉換器將字段中的字符串數據轉換爲Bean中的密碼變量。提交後Primefaces表單使用AJAX，可能存在問題。如果我填寫完整的表格，沒有驗證錯誤，一切正常。但是，如果有一個有效的錯誤，並且沒有轉換器錯誤（我檢查轉換器中的密碼長度），整個表單就完全停止工作。我必須刷新頁面才能再次運行。
這裏有一些來源：
密碼類：
public class Password {
public static final short MIN_LENGTH = 5;
private String text;
private String hash;
public Password(String text) {
this.text = text;
this.hash = Hasher.sha512(text);
}
/**
* Get password instance with known hash only
* @param hash SHA-512 hash
* @return Password instance
*/
public static Password getFromHash(String hash) {
Password password = new Password(null);
password.hash = hash;
return password;
}
@Override
public int hashCode() {
return hash.hashCode();
}
@Override
public boolean equals(Object obj) {
if (obj == null) {
return false;
}
if (getClass() != obj.getClass()) {
return false;
}
final Password other = (Password) obj;
if ((this.hash == null) ? (other.hash != null) : !this.hash.equals(other.hash)) {
return false;
}
return true;
}
@Override
public String toString() {
return hash;
}
/**
* @return the text
*/
public String getText() {
return text;
}
}
密碼器：
<h:form id="registration">
<p:panelGrid columns="3">
<h:outputLabel value="#{commonTxt.email}:" for="email" />
<p:inputText id="email" value="#{userRegistrationForm.email}" required="true" requiredMessage="#{formsTxt.msgEmpty}">
<f:validator validatorId="email" />
<f:validator validatorId="unique" />
<f:attribute name="entity" value="SystemUser" />
<f:attribute name="field" value="email" />
<f:attribute name="uniqueMessage" value="#{formsTxt.nonUniqueEmail}" />
</p:inputText>
<p:message for="email" />
<h:outputLabel value="#{usersTxt.password}:" for="password" />
<p:password id="password" value="#{userRegistrationForm.password}" binding="#{password}" autocomplete="off" feedback="true" weakLabel="#{formsTxt.passwordWeak}" goodLabel="#{formsTxt.passwordGood}" strongLabel="#{formsTxt.passwordStrong}" promptLabel="#{formsTxt.passwordPrompt}" />
<p:message for="password" />
<h:outputLabel value="#{usersTxt.passwordCheck}:" for="passwordCheck" />
<p:password id="passwordCheck" value="#{userRegistrationForm.passwordCheck}" binding="#{passwordCheckInput}" autocomplete="off">
<f:validator validatorId="match" />
<f:attribute name="matchAgainst" value="#{password}" />
<f:attribute name="matchMessage" value="#{formsTxt.passwordMismatch}" />
</p:password>
<p:message for="passwordCheck" />
<p:column /><p:column /><p:column />
<h:outputLabel value="#{usersTxt.name}:" for="name" />
<p:inputText id="name" value="#{userRegistrationForm.name}" maxlength="255" required="true" requiredMessage="#{formsTxt.msgEmpty}" />
<p:message for="name" />
<f:facet name="footer">
<p:commandButton value="#{usersTxt.register}" action="#{userRegistrationForm.register()}" update="registration" />
</f:facet>
</p:panelGrid>
</h:form>
我不會發布：
@FacesConverter(forClass = Password.class)
public class PasswordConverter implements Converter {
@Override
public Object getAsObject(FacesContext context, UIComponent component, String value) {
String text = (String) value;
if (text.length() >= Password.MIN_LENGTH) {
return new Password(text);
}
FacesMessage msg = new FacesMessage(Texter.get("forms/forms", "shortPassword").replace("%limit%", String.valueOf(Password.MIN_LENGTH)));
msg.setSeverity(FacesMessage.SEVERITY_ERROR);
throw new ConverterException(msg);
}
@Override
public String getAsString(FacesContext context, UIComponent component, Object value) {
try {
Password password = (Password) value;
return password.getText();
} catch (Exception ex) {
throw new ConverterException(ex);
}
}
}
中的facelet形式豆的代碼，有兩個密碼屬性與getter和setter。
任何有助於解決我的問題的幫助表示讚賞。提前致謝。
