tomcat - 无法在服务器上运行应用程序

Question

我想尝试 salesforce.com 上的 oauth servlet 示例。

但问题是我无法在服务器上运行应用程序，因为它总是失败并出现相同的错误

我创建了动态网络项目，我的项目结构如下所示

我完全复制的Servlet

@WebServlet(name = "oauth", urlPatterns = { "/oauth/*", "/oauth" }, initParams = {
    @WebInitParam(name = "clientId", value = "xxxx"),
    @WebInitParam(name = "clientSecret", value = "xxxx"),
    @WebInitParam(name = "redirectUri", value = "https://localhost:8443/DemoREST/oauth/_callback"),
    @WebInitParam(name = "environment", value = "https://login.salesforce.com"), })
public class OAuthServlet extends HttpServlet {
private static final long serialVersionUID = 1L;

private static final String ACCESS_TOKEN = "ACCESS_TOKEN";
private static final String INSTANCE_URL = "INSTANCE_URL";

private String clientId = null;
private String clientSecret = null;
private String redirectUri = null;
private String environment = null;
private String authUrl = null;
private String tokenUrl = null;

public void init() throws ServletException {
    clientId = this.getInitParameter("clientId");
    clientSecret = this.getInitParameter("clientSecret");
    redirectUri = this.getInitParameter("redirectUri");
    environment = this.getInitParameter("environment");

    try {
        authUrl = environment
                + "/services/oauth2/authorize?response_type=code&client_id="
                + clientId + "&redirect_uri="
                + URLEncoder.encode(redirectUri, "UTF-8");
    } catch (UnsupportedEncodingException e) {
        throw new ServletException(e);
    }

    tokenUrl = environment + "/services/oauth2/token";
}

protected void doGet(HttpServletRequest request,
        HttpServletResponse response) throws ServletException, IOException {
    String accessToken = (String) request.getSession().getAttribute(
            ACCESS_TOKEN);

    if (accessToken == null) {
        String instanceUrl = null;

        if (request.getRequestURI().endsWith("oauth")) {
            // we need to send the user to authorize
            response.sendRedirect(authUrl);
            return;
        } else {
            System.out.println("Auth successful - got callback");

            String code = request.getParameter("code");

            HttpClient httpclient = new HttpClient();

            PostMethod post = new PostMethod(tokenUrl);
            post.addParameter("code", code);
            post.addParameter("grant_type", "authorization_code");
            post.addParameter("client_id", clientId);
            post.addParameter("client_secret", clientSecret);
            post.addParameter("redirect_uri", redirectUri);

            try {
                httpclient.executeMethod(post);

                try {
                    JSONObject authResponse = new JSONObject(
                            new JSONTokener(new InputStreamReader(
                                    post.getResponseBodyAsStream())));
                    System.out.println("Auth response: "
                            + authResponse.toString(2));

                    accessToken = authResponse.getString("access_token");
                    instanceUrl = authResponse.getString("instance_url");

                    System.out.println("Got access token: " + accessToken);
                } catch (JSONException e) {
                    e.printStackTrace();
                    throw new ServletException(e);
                }
            } finally {
                post.releaseConnection();
            }
        }

        // Set a session attribute so that other servlets can get the access
        // token
        request.getSession().setAttribute(ACCESS_TOKEN, accessToken);

        // We also get the instance URL from the OAuth response, so set it
        // in the session too
        request.getSession().setAttribute(INSTANCE_URL, instanceUrl);
    }

    response.sendRedirect(request.getContextPath() + "/DemoREST");
}
}

但是当我尝试在服务器上运行时出现错误。

Answer 1

错误是:java.lang.ClassNotFoundException: org.apache.commons.httpclient.HttpMethod。

您需要添加 Apache HTTP Client , Apache HTTP Core和 Commons Codec到您的 lib 目录。
