PrimeFaces 3.x中的UTF-8 [英] UTF-8 in PrimeFaces 3.x

问题描述

我有一个非常简单的应用程序，我的索引页中有一个inputtext和一个转到page2.xhtml的按钮.

I have a very simple application,there is an inputtext in my index page and a button to go to page2.xhtml.

    <h:body>
        <h:form>
            <h:inputText value="#{mainBean.testValue}"/>
            <p:commandButton update="myoutput" value="ajax call" ajax="false"/>
            <p:separator />
            <h:commandButton action="#{mainBean.gotoPageTwo}" value="goto Page2"/>
            <br/>
            <h:outputText value="#{mainBean.testValue}" id="myoutput"/>
        </h:form>
    </h:body>
</html>

我使用PrimeFaces 2.2.1测试了此应用程序，没有问题. 但提交上述每个按钮后，我的UTF-8字符将被销毁. 我测试了过滤器，但是它不起作用. 是PrimeFaces 3.x中的错误吗? 谁能解决这个问题?

I tested this application with PrimeFaces 2.2.1 and there was no problem. but after submit each of the above button, my UTF-8 characters will destroy. I tested filter but it don't work. Is it a bug in PrimeFaces 3.x? Can any body solve this problem?

推荐答案

在PrimeFaces论坛上找到的答案的web.xml示例不完整. <filter-mapping>丢失.没有它，过滤器甚至根本不会运行.相应地添加

The web.xml example of the answer you found at PrimeFaces forum is incomplete. The <filter-mapping> is missing. Without that, the filter won't even run at all. Add it accordingly

<filter-mapping>
    <filter-name>Character Encoding Filter</filter-name>
    <url-pattern>/*</url-pattern>
</filter-mapping>

当您已经使用Servlet 3.0(Tomcat 7，Glassfish 3等)时，另一种方法是仅使用

When you're already on Servlet 3.0 (Tomcat 7, Glassfish 3, etc), an alternative is to use just the @WebFilter annotation on the class. Don't forget to remove the filter entry from web.xml.

@WebFilter("/*")
