【问题描述】：

我在加载 JSF 页面时遇到了下面提到的错误。页面加载成功，页面上所需的操作也完成了，但是出现了这个错误。

JSF 页面包含选项卡面板，如果我尝试将可用项目中的某些项目包含到包含的项目中，则会出现错误。以下是列表的 XHTML。

我正在尝试使用列表穿梭从左侧到右侧添加一些项目，并且在日志中出现以下异常（仅在 FireFox 浏览器中，未在 Google Chrome 中观察到此问题）（能够应用所有更改正确，只是得到以下异常）。我的 FireFox 版本是 35.0.1

谷歌搜索我发现“问题似乎是像'！'这样的字符由 FireFox 转换为 '%21'。以下过滤器会将 %21 转换回 '!'所以资源可以在服务器中找到”

就我而言，我只是在日志中收到异常，但所有源都已成功加载

为了消除异常，我添加了过滤器

package juno.sa.server;

import java.io.IOException;
import java.io.UnsupportedEncodingException;
import java.net.URLDecoder;

import javax.servlet.Filter;
import javax.servlet.FilterChain;
import javax.servlet.FilterConfig;
import javax.servlet.ServletException;
import javax.servlet.ServletRequest;
import javax.servlet.ServletResponse;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletRequestWrapper;

public class RichFacesFirefox11Filter implements Filter {

    @Override
    public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain) throws IOException, ServletException {
        chain.doFilter(new HttpServletRequestWrapper((HttpServletRequest) request) {
            @Override
            public String getRequestURI() {
                try {
                    return URLDecoder.decode(super.getRequestURI(), "UTF-8");
                } catch (UnsupportedEncodingException e) {

                    throw new IllegalStateException("Cannot decode request URI.", e);
                }
            }
        }, response);
    }

    @Override
    public void init(FilterConfig filterConfig) throws ServletException {
        // do nothing
    }

    @Override
    public void destroy() {
        // do nothing
    }
}

【问题讨论】：

那么如果您的资源正在加载并且过滤器阻止了异常，那么问题是什么？
资源已加载，但我在日志中收到异常，我不想出现该异常

标签： jsf firefox richfaces servlet-filters

【解决方案1】：

即使我收到这样的异常。引起：java.util.zip.ZipException：数据检查不正确在 java.util.zip.InflaterInputStream.read(InflaterInputStream.java:147)

但在我的情况下，根本原因是我尝试读取的流是使用 flate 编码器压缩的，因此尝试解压缩的流是 InflaterInputStream。

在我的情况下，最后一个字节中存在的数据不是 eof 参数，而是实际数据，eof 参数存在于流中最后一个字节之前的某个位置。因此，当流读取块数据的最后一个字节时，它无法找到 eof 从而引发不正确的数据检查。

也许在你的最后验证它......它也可能在你的最后是同样的问题。
