【中文标题】Jersey - servlet 上下文路径和/或 servlet 路径包含百分比编码的字符【英文标题】：Jersey - The servlet context path and/or the servlet path contain characters that are percent encoded 【发布时间】：2015-05-14 22:16:40 【问题描述】：我正在使用 Jersey 和 Tomcat，每次单击链接时都会收到以下消息：
HTTP Status 500 - The servlet context path and/or the servlet path contain
characters that are percent encoded
type: Exception report
message: The servlet context path and/or the servlet path contain characters
that are percent encoded
description: The server encountered an internal error that prevented it from
fulfilling this request.
exception:
javax.ws.rs.ProcessingException: The servlet context path and/or the servlet path
contain characters that are percent encoded
org.glassfish.jersey.servlet.ServletContainer.service(ServletContainer.java:317)
org.glassfish.jersey.servlet.ServletContainer.service(ServletContainer.java:221)
org.apache.tomcat.websocket.server.WsFilter.doFilter(WsFilter.java:52)
note: The full stack trace of the root cause is available in the Apache Tomcat/7.0.56
logs.
REST服务的路径是：
http://localhost:8070/simple-service-webapp/rest/hello
当我在 URL 栏中输入它时，它可以工作，但是当我点击某个链接时，URL 变成了这样：
http://localhost:8070/simple%2Dservice%2Dwebapp/rest/hello
不知何故，Jersey 默认不处理百分比编码的 URL。
有人可以帮我在不删除 URL 中的破折号的情况下让它工作吗？我的搜索没有提供有效的解决方案。

【问题讨论】：
这个有什么解决办法吗？？ 只是不要使用任何将被百分比编码的字符不能被接受作为答案。 ???? 【参考方案1】：我遇到了这个确切的问题。将您的工件 id 更改为“SimpleWebApp”之类的东西（注意我去掉了'-'）并且它可以工作。对于我想做的事情，不值得找出这行不通的确切原因。我不认为是球衣，而是关于 tomcat 的东西。
mvn archetype:generate -DarchetypeArtifactId=jersey-quickstart-webapp \
-DarchetypeGroupId=org.glassfish.jersey.archetypes -DinteractiveMode=false \
-DgroupId=com.example -DartifactId=SimpleWebapp -Dpackage=com.example \
-DarchetypeVersion=2.22.1
【讨论】：
【参考方案2】：看来jetty 9.4标准编码request.getContextPath()，见Jetty 9.4 ServletContextHandler.setContextPath behavior or Request data change。
和调试球衣（版本 2.30.1 -> 2.35）ServletContainer 我发现以下代码（第 94 行+）：
String decodedBasePath = request.getContextPath() + servletPath + "/";
String encodedBasePath = UriComponent.encode(decodedBasePath, Type.PATH);
if (!decodedBasePath.equals(encodedBasePath))
this.setResponseForInvalidUri(response, new ProcessingException("The servlet context path and/or the servlet path contain characters that are percent encoded"));
else
所以 Jersey 不希望 request.getContextPath() 被编码。
即看来球衣需要升级以适应新的 jetty 9.4 行为！
在那之前，我们将无法拥有例如URL 中的空格按以前的方式处理...
