我正在使用Jersey和Tomcat，每当我点击链接时，我都会收到以下消息：
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，它可以正常工作，但是当我点击路径某处的链接时，URL就变成了这个：
http://localhost:8070/simple%2Dservice%2Dwebapp/rest/hello
默认情况下，Jersey不会处理百分比编码的URL。
有人可以帮助我在不删除网址中的短划线的情况下开始工作吗？我的搜索没有提供有效的解决方案。
HelloResource.java
package com.example;
import javax.ws.rs.*;
import javax.ws.rs.core.Context;
import javax.ws.rs.core.MediaType;
import javax.ws.rs.core.UriInfo;
@Path("hello")
public class HelloResource {
@GET
@Produces(MediaType.TEXT_PLAIN)
public String sayHelloPlainText(@Context UriInfo uriInfo) {
String name = uriInfo.getQueryParameters().getFirst("name");
if (name == null) {
name = "unknown user";
}
return "Hello " + name + "!";
}
@GET
@Produces(MediaType.TEXT_HTML)
public String sayHelloHtml(@Context UriInfo uriInfo) {
String text = sayHelloPlainText(uriInfo);
String result = "<html>" + "<head>" + "<title>Hello Jersey</title>" + "</head>"
+ "<body>" + "<h1>" + text + "</h1>" + "</body>" + "</html>";
return result;
}
@GET
@Produces(MediaType.TEXT_XML)
public String sayHelloXml(@Context UriInfo uriInfo) {
String text = sayHelloPlainText(uriInfo);
String result = "<?xml version=\"1.0\"?>" + "<hello>Hello " + text + "!" + "</hello>";
return result;
}
}

我遇到了这个问题。将您的工件ID更改为“SimpleWebApp”（注意我取出了' - '）并且它可以工作。对于我想做的事情，不值得找出为什么这不起作用的确切原因。我认为这不是运动衫，而是关于tomcat的事情。
function FindPath(start, finish, path)
--Define a table to hold the paths
local paths = {}
--Make a default argument
path = path or {start}
--Loop through connected nodes
for i,v in ipairs(start:GetConnectedParts()) do
--Determine if backtracking
local loop = false
for i,vv in ipairs(path) do
if v == vv then
loop = true
end
end
if not loop then
--Make a path clone
local npath = {unpack(path)}
npath[#npath+1] = v
if v == finish then
--If we reach the end add the path
return npath
else
--Otherwise add the shortest part extending from this node
paths[#paths+1] = FindPath(v, finish, npath) --NOTED HERE
end
end
end
--Find and return the shortest path
if #paths > 0 then
local lengths = {}
for i,v in ipairs(paths) do
lengths[#lengths+1] = #v
end
local least = math.min(unpack(lengths))
for i,v in ipairs(paths) do
if #v == least then
return v
end
end
end
end
