Obtenez les lettres à la servlet dans le bon sens

Question

J'ai un formulaire jsp html où les utilisateurs peuvent copier leur texte presse soumettre et pdf est créé en utilisant Itext. De l'autre côté, la servlet obtient les données. Qu'est-ce qui se passe est quand j'utilise des lettres non standard, il me renvoie #^& pour ces lettres. J'ai utilisé dans mon servler et les deux jsp charset = UTF-8, j'utilise la méthode post pour envoyer des données. J'utilise netbeans et tomcat. Il ne s'agit pas de Itext puisque lorsque je fais System.out.println (variable), il ne s'imprime pas correctement.

Answer 1

1) Vous devez définir le type de contenu de données à utf-8 avant de soumettre les données. Parce récepteur (dans ce cas, servlet) doit savoir quel codage a été défini (dans JSP) pour les données avant servlet effectivement décode les octets.

ie:request.setCharacterEncoding("UTF-8");

2)<%@page pageEncoding="UTF-8"%> est pas utilisé pour les données de Java. Cette ligne est utilisée pour indiquer dans quelle langue le fichier JSP a été écrit. ie: Anglais, Chinois. Je pense que vous avez totalement mal compris cette ligne.

Réponse Mise à jour:

3) cette ligne >> Supprimer String(request.getParameter("brokerstext").getBytes("iso-8859-1")), "UTF-8"); Vous n'avez pas besoin de convertir reçus octets UTF-8 à iso.

Note: S'il vous plaît envoyer votre code JSP

Answer 2

Le problème est que lors de l'analyse de la forme des champs tomcat ne connaît pas le jeu de caractères utilisé.

Ceci est normalement résolu à l'aide d'un filtre qui modifie le jeu de caractères dans la requête.

Créer la classe suivante:

public class EncodingSetterFilter implements Filter 
{ 

    /** Creates a new instance of EncodingSetterFilter */ 
    public EncodingSetterFilter() 
    { 
    } 

    public void init(FilterConfig filterConfig) throws ServletException 
    { 
    } 

    public void doFilter(ServletRequest servletRequest, ServletResponse servletResponse, FilterChain filterChain) throws IOException, ServletException 
    { 
     servletRequest.setCharacterEncoding("UTF-8"); 
     filterChain.doFilter(servletRequest, servletResponse); 
    } 

    public void destroy() 
    { 
    } 
} 

Et puis configurer son utilisation dans web.xml (assurez-vous de spécifier la classe de filtre correct):

<filter> 

    <filter-name>EncodingFilter</filter-name> 
    <filter-class> 
     com.yourpackage.EncodingFilter 
    </filter-class> 
</filter> 

<filter-mapping> 
    <filter-name>EncodingFilter</filter-name> 
    <url-pattern>/*</url-pattern> 
</filter-mapping>
