我使用 jsf 和使用 netbeans 7.3.1 的 eclispeLink 开发了一个 java 应用程序，但我的角色没有正确保存。我查看了请求变量，发现我的角色没有正确显示在请求对象中。

我的 Jsf 样本：

    <ui:composition template="/template.xhtml">

                <h:panelGrid columns="2">
                    <h:outputLabel value="#{bundle.CreateTblAccessLabel_id}" for="id" />
                    <h:inputText id="id" value="#{tblAccessController.selected.id}" title="#{bundle.CreateTblAccessTitle_id}" required="true" requiredMessage="#{bundle.CreateTblAccessRequiredMessage_id}"/>
                    <h:outputLabel value="#{bundle.CreateTblAccessLabel_userName}" for="userName" />
                    <h:inputText id="userName" value="#{tblAccessController.selected.userName}" title="#{bundle.CreateTblAccessTitle_userName}" />
                    <h:outputLabel value="#{bundle.CreateTblAccessLabel_userTypeId}" for="userTypeId" />
                    <h:selectOneMenu id="userTypeId" value="#{tblAccessController.selected.userTypeId}" title="#{bundle.CreateTblAccessTitle_userTypeId}" >
                        <f:selectItems value="#{tblUserTypeController.itemsAvailableSelectOne}"/>
                    </h:selectOneMenu>
                    <h:outputLabel value="#{bundle.CreateTblAccessLabel_formId}" for="formId" />
                    <h:selectOneMenu id="formId" value="#{tblAccessController.selected.formId}" title="#{bundle.CreateTblAccessTitle_formId}" required="true" requiredMessage="#{bundle.CreateTblAccessRequiredMessage_formId}">
                        <f:selectItems value="#{tblFormController.itemsAvailableSelectOne}"/>
                    </h:selectOneMenu>
                    <h:outputLabel value="#{bundle.CreateTblAccessLabel_activitesId}" for="activitesId" />

                    </h:selectOneMenu>

                <br />

                <h:commandLink action="#{tblAccessController.prepareList}" value="#{bundle.CreateTblAccessShowAllLink}" immediate="true"/>

                <h:link outcome="/index" value="#{bundle.CreateTblAccessIndexLink}"/>
            </h:form>
        </ui:define>
    </ui:composition>

</html>

MY 过滤器更改编码：

public class EncodingFilter implements Filter{

    private String encoding;

    @Override
    public void init(FilterConfig filterConfig) throws ServletException {
        encoding = filterConfig.getInitParameter("requestEncoding");
        if( encoding==null ) encoding="UTF-8";
    }

    @Override
    public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain) throws IOException, ServletException {
        HttpServletRequest httpRequest = (HttpServletRequest) request;
        HttpServletResponse httpResponse = (HttpServletResponse) response;
        httpRequest.setCharacterEncoding(encoding);
        httpResponse.setCharacterEncoding(encoding);
        response.setContentType("text/html;charset=utf-8");
        chain.doFilter(httpRequest, httpResponse);
    }

    @Override
    public void destroy() {
        throw new UnsupportedOperationException("Not supported yet."); 
    }

}

我的模板.xhtml

<html xmlns="http://www.w3.org/1999/xhtml"
      xmlns:ui="http://xmlns.jcp.org/jsf/facelets"
      xmlns:h="http://xmlns.jcp.org/jsf/html">

        <title><ui:insert name="title">Default Title</ui:insert></title>
        <h:outputStylesheet name="css/jsfcrud.css"/>
    </h:head>

    <h:body>

            <ui:insert name="body">Default Body</ui:insert>
        </p>
    </h:body>
</html>

问题是什么？我该如何解决？

一切看起来都很好！您应该检查以下内容：

a) 检查您的 Glassfish Resources 内部是否有以下内容：

<property name="useUnicode" value="true"/>
<property name="characterEncoding" value="UTF8"/>

b) 你的数据库和表是否是 UTF-8 CHARCTER SET

对于 mysql 使用以下代码：

ALTER DATABASE dbname DEFAULT CHARACTER SET utf8;

USE dbname;

ALTER TABLE tblname CONVERT TO CHARACTER SET utf8 COLLATE utf8_general_ci;
