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，它起作用了，但是当我点击某处的链接时，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。
有人可以帮助我在不删除 URL 中的破折号的情况下使它正常工作吗？我的搜索没有提供有效的解决方案。

最佳答案
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(请注意，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。我不认为它是 Jersey ，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
关于java - Jersey - servlet 上下文路径和/或 servlet 路径包含百分比编码的字符，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/29015175/
