Question

当我将Mojarra从2.2.1升级到2.2.3 （JBoss Wildfly Alpha到Beta）时出现了问题。

当我尝试提交带有特殊字符（波兰语字母）的表单（POST）时，它们不能正确地进行UTF-8编码。

我做了什么？

写了一个过滤器

@WebFilter(urlPatterns = "/*", initParams = { @WebInitParam(name = "ignore", value = "true" ), @WebInitParam(name = "encoding", value = "UTF-8") })
public class CharacterEncodingFilter implements Filter {

    private String encoding = null;
    private FilterConfig filterConfig;

    // Should a character encoding specified by client be ignored
    private boolean ignore = true;

    @Override
    public void init(FilterConfig filterConfig) throws ServletException {
        this.filterConfig = filterConfig;
        this.encoding = filterConfig.getInitParameter("encoding");
        String value = filterConfig.getInitParameter("ignore");

        this.ignore = ((value == null) || value.equalsIgnoreCase("true") || value.equalsIgnoreCase("yes"));
    }

    @Override
    public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain) throws IOException, ServletException {

        if ((ignore || (request.getCharacterEncoding() == null)) && (encoding != null)) {
            request.setCharacterEncoding(encoding);
            response.setCharacterEncoding(encoding);
        }

        chain.doFilter(request, response);
    }

    @Override
    public void destroy() {
        this.encoding = null;
        this.filterConfig = null;
    }
}

每个XHTML都包含一行

<?xml version="1.0" encoding="UTF-8"?>
布局还包含有关编码的信息

<meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />

为standalone.xml添加了属性

<property name="org.apache.catalina.connector.URI_ENCODING" value="UTF-8"/>
<property name="org.apache.catalina.connector.USE_BODY_ENCODING_FOR_QUERY_STRING" value="true"/>
<property name="file.encoding" value="UTF-8"/>

我如何初始化JSF页面

<f:metadata>
    <f:viewParam name="name" value="#{followNewView.name}" />
    <f:viewParam name="company" value="#{followNewView.company}" />
    <f:viewParam name="companyURL" value="#{followNewView.companyURL}" />
    <f:viewAction action="#{followNewView.init}" />
</f:metadata>

最后我还是以不正确的编码结束： enter image description here

Answer 1

问题在于Undertow编码。

此处的解决方案：https://issues.jboss.org/browse/WFLY-2533

Answer 2

这是关于此的Bug：

https://issues.jboss.org/browse/WFLY-2550

这是一个可能的解决方案：

在web.xml中过滤后添加：

<filter-mapping>
    <filter-name>CDI Conversation Filter</filter-name>
    <url-pattern>/*</url-pattern>
</filter-mapping>

如下所述：
