Jersey - servlet 上下文路徑和/或 servlet 路徑包含百分比編碼的字符

[英]Jersey - The servlet context path and/or the servlet path contain characters that are percent encoded

我正在使用 Jersey 和 Tomcat,每次單擊鏈接時都會收到以下消息:

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服務的路徑是:

http://localhost:8070/simple-service-webapp/rest/hello

當我在 URL 欄中輸入它時,它可以工作,但是當我點擊某個鏈接時,URL 變成了這樣:

http://localhost:8070/simple%2Dservice%2Dwebapp/rest/hello

不知何故,Jersey 默認不處理百分比編碼的 URL。

有人可以幫助我在不刪除 URL 中的破折號的情況下使其工作嗎? 我的搜索沒有提供有效的解決方案。

我遇到了這個問題。 將您的工件ID更改為“SimpleWebApp”(注意我取出了' - ')並且它可以工作。 對於我想做的事情,不值得找出為什么這不起作用的確切原因。 我不認為這是運動衫,而是關於tomcat的東西。

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

看起來 jetty 9.4 標准編碼 request.getContextPath(),請參閱Jetty 9.4 ServletContextHandler.setContextPath 行為或請求數據更改

並調試球衣(版本 2.30.1 -> 2.35 ) ServletContainer 我發現以下代碼(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() 被編碼。

即看起來球衣需要升級以適應新的碼頭 9.4 行為!

在那之前,我們將無法像以前那樣處理 URL 中的空格……
