Struts2.1.6 中文乱码问题

Struts2.1.6 StrutsPrepareAndExecuteFilter bug

在用strust2.1.6做小项目,结果居然发现在post数据的时候,居然有乱码。
自认为对编码也算了解,立马check应用的content type,struts2配置的struts.locale,struts.i18n.encoding,没错,都是统一使用了UTF-8。
那是为什么呢?没办法,只能debug应用,结果发现:

public void doFilter(ServletRequest req, ServletResponse res, FilterChain chain) throws IOException, ServletException {

        HttpServletRequest request = (HttpServletRequest) req;
        HttpServletResponse response = (HttpServletResponse) res;

        try {
            prepare.createActionContext(request, response);            prepare.assignDispatcherToThread();
            prepare.setEncodingAndLocale(request, response);
            request = prepare.wrapRequest(request);
            ActionMapping mapping = prepare.findActionMapping(request, response);
            if (mapping == null) {
                boolean handled = execute.executeStaticResourceRequest(request, response);
                if (!handled) {
                    chain.doFilter(request, response);
                }
            } else {
                execute.executeAction(request, response, mapping);
            }
        } finally {
            prepare.cleanupRequest(request);
        }
    }


1) prepare.createActionContext(request, response);
2) prepare.setEncodingAndLocale(request, response);
setEncodingAndLocale居然在createActionContext之后,在没有设置正确的encoding之前,解析request中的parameters,能成吗?

无奈之下,只能暂时用CharacterEncodingFilter这个filter设置request的character,猥琐地临时解决问题。

今天打算向Struts提交bug的时候,发现该bug在2.1.7版本中被修复,详见:https://issues.apache.org/struts/browse/WW-3075%3Bjsessionid=3EAC5B44A949CA77B4471AA0D45754E9?page=com.atlassian.jira.plugin.ext.subversion%3Asubversion-commits-tabpanel

哎,在使用2.1.7之前,先用CharacterEncodingFilter吧 :)
