JSP 客户端测试 Servlet 部署 RESTful 网络服务

JSP client to test Servlet-deployed RESTful webservice

我最近使用 restlet.org 框架在 Eclipse 中创建了一个简单的 servlet 部署的 web 服务(使用 Tomcat),我可以使用它在浏览器中显示文本文件中的文本。我还创建了一个具有简单形式的 JSP (input.jsp):一个文本框和一个按钮。当用户输入一个词并单击按钮时,第二个 JSP (result.jsp) 应该打开,仅显示包含该词的文本文件的短语。

我想使用这些 JSP 构建一个测试客户端来测试我的网络服务,但我真的不知道该怎么做。这两个 JPS 当前都位于我项目的 /WEB-INF 文件夹中,但是如果我尝试 运行 我服务器上的第一个 JSP,则会弹出一条错误消息:"The server has not found anything matching the request URI" .只需导航到下面的 QuotesApplication class 中定义的 URI 就可以很好地工作。

申请class:

package edu.ap.rest;

import org.restlet.Application;
import org.restlet.Restlet;
import org.restlet.routing.Router;

public class QuotesApplication extends Application {

    /**
     * Creates a root Restlet that will receive all incoming calls.
     */
   @Override
   public synchronized Restlet createInboundRoot() {

       Router router = new Router(getContext());

       router.attach("/quotes", QuotesResource.class);
       router.attach("/quotes/{searchTerm}", QuotesSearchResource.class);
       return router;
   }
}

资源 1:

package edu.ap.rest;

import org.restlet.resource.Get;
import org.restlet.resource.Post;
import org.restlet.resource.ServerResource;

import edu.ap.txt.TXTParser;

public class QuotesResource extends ServerResource {

    @Get("html")
    public String getQuotes() {
        TXTParser parser = new TXTParser();
        return parser.getQuotes();
    }

}

资源 2:

package edu.ap.rest;

import org.restlet.resource.Get;
import org.restlet.resource.Post;
import org.restlet.resource.ServerResource;

import edu.ap.txt.TXTParser;

public class QuotesSearchResource extends ServerResource {

    @Get("html")
    public String getSearchQuotes(String searchTerm) {
        searchTerm = getAttribute("searchTerm");
        TXTParser parser = new TXTParser();
        return parser.getSearchQuotes(searchTerm);
    }
}

输入JSP:

<%@ page language="java" contentType="text/html; charset=UTF-8"
    pageEncoding="UTF-8"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>Zoek een quote</title>
</head>
<body>

  <form method="POST" action="Result.jsp">
    Zoekterm: <input type="text" name="searchTerm"><br/>
    <br/><br/>
    <input type="submit" value="Submit">
  </form>

</body>
</html>

Result.jsp:

<%@ page language="java" contentType="text/html; charset=UTF-8"
 pageEncoding="UTF-8"%>
<%@page import="edu.ap.rest.*"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">

<% 
 QuotesSearchResource resource = new QuotesSearchResource();
 String searchTerm = ("searchTerm");
 System.out.println("Test: " + searchTerm);
 String Result = resource.getSearchQuotes(searchTerm);
%>
<body>
<%= Result %>
</body>
</html>

JSP 也是一个 servlet。 您错过了这样的部分:

<servlet>
    <servlet-name>QuoteInputServlet</servlet-name>
    <jsp-file>/Input.jsp</jsp-file>
</servlet>

<servlet-mapping>
    <servlet-name>QuoteInputServlet</servlet-name>
    <url-pattern>/input</url-pattern>   
</servlet-mapping>
