Question

我们正在运行嵌入在码头容器中的Web应用程序。在jsp上有一个jsp：forward。 jsp：param的值为ISO-8859-1。我如何告诉Jetty，URL是ISO-8859-1？

系统属性org.eclipse.jetty.util.UrlEncoding.charset无效。 org.eclipse.jetty.util.Utf8Appendable$NotUtf8Exception: Not valid UTF8! incomplete UTF8 sequence...被抛出。

以下是jsp的一个示例：

<%@ page language="java" pageEncoding="ISO-8859-1" %>
...
<jsp:forward page="/forwardToAServlet">
<jsp:param name="param1" value="an+example+with+an+umlaut+gr%F6%DFere" />
</jsp:forward>

这里是stacktrace：

我在类org.eclipse.jetty.server.Request的方法mergeQueryString（String query）的源代码中找到了以下内容：

UrlEncoded.decodeTo(query,parameters, StandardCharsets.UTF_8,-1); //have to assume UTF-8 because we can't know otherwise

因此在方法URLEncoded.decodeTo（）中使用UTF-8而不是使用System.setProperty（“org.eclipse.jetty.util.UrlEncoding.charset”，“ISO-8859-1”）的编码集

我能以某种方式解决这个问题吗？有任何想法吗？： - ）

我怀疑这是Jetty 9.1.0中的一个错误。

所以我在https://bugs.eclipse.org/423692

提交了

缺点是Dispatcher.forward()需要执行Request.mergeQueryString()，但因为这将解码传入的查询字符串that decoding step is hardcoded at UTF8（HTTP的默认值），阻止您在org.eclipse.jetty.util.UrlEncoding.charset属性中指定的重写编码/字符集。

Jetty项目上的HTTP规范引导将评估这是Jetty中的有效错误还是HTTP规范的要求，并且必须保留原样。

遵循该错误，同时考虑在任何地方使用UTF-8，因为这是网络的事实上的编码。（例如：HTTP / 2规范的早期指示也表明内容/文档编码将保持不变，但协议编码将严格按UTF-8强制执行）
