如何訪問的tomcat的servlet在Maven項目結構，嵌入式的tomcat

Question

我使用的是嵌入在Tomcat Maven項目結構
（喜歡這裏：https://devcenter.heroku.com/articles/create-a-java-web-application-using-embedded-tomcat）
但林不部署到Heroku的。
我可以訪問index.jsp（甚至在添加web.xml之前）localhost:8080/
但是我不能鍛鍊如何訪問我的servlet（即使在添加web.xml之前也要獲得404）。
在localhost:8080/Archery
試圖嘗試過localhost:8080/servlets/servlet.ArcheryShootServlet
在localhost:8080/servlet/servlet.ArcheryShootServlet
在localhost:8080/servlet.ArcheryShootServlet
在localhost:8080/target/Archery
在localhost:8080/target/ArcheryShootServlet
嘗試嘗試嘗試嘗試過localhost:8080/target/servlet.ArcheryShootServlet

我試圖把它們放入資源文件夾嘗試這已經是該項目的一部分。

我試着加入webResources文件夾，並將其添加到
POM文件配置：

Answer 1

你的應用程序上下文路徑/Archery（在context.xml定義）

你的servlet路徑也是/Archery（的urlPatterns屬性@WebServlet） 它也通過你的web.xml複製

那麼，您的網址應爲localhost:8080/Archery/Archery

第一服務器[：端口]，其次是上下文路徑，其次是servlet路徑

無論如何，你會必須修復項目結構才能運作。 如果你是以下Maven約定的網絡資源目錄應該是src/main/webapp 的web.xml（和context.xml）應WEB-INF目錄下這個目錄下放置。

你已經打包戰爭結束後，只要確保這些文件存在（在WEB-INF）
