创建对象MockHttpServletResponse进行单元测试时出错

  1. 我试图使用sprint-test和模仿对象编写Servlet的单元测试

  2. 我的Maven依赖是： 

    <dependency>

    org.springframework

    spring-test

    4.0.3.RELEASE

我只想测试Java servlet，例如以下有关 书：

package sample;
import java.io.IOException;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
public class LoginServlet extends HttpServlet {
    private boolean isValid;
    /**
     * 
     */
    private static final long serialVersionUID = 2473252741884321641L;
    @Override
    public void init() throws ServletException {
        super.init();
    }
    @Override
    public void doPost(HttpServletRequest req, HttpServletResponse resp)
            throws IOException {
        String user = req.getParameter("j_username");
        String pass = req.getParameter("j_password");
        if (isValidLogin(user, pass)) {
            resp.sendRedirect("/frontpage");
            req.getSession().setAttribute("username", user);
        } else {
            resp.sendRedirect("/invalidlogin");
        }
    }
    private boolean isValidLogin(String user, String pass) {
        return isValid;
    }
    public void setValid(boolean isValid) {
        this.isValid = isValid;
    }
}

我的代码是：

    package sample;
    import static org.junit.Assert.assertEquals;
    import org.junit.Test;
    import org.springframework.mock.web.MockHttpServletRequest;
    import org.springframework.mock.web.MockHttpServletResponse;
    public class SprintTestProb {
    @Test
    public void wrongPasswordShouldRedirectToErrorPage() throws Exception {
        MockHttpServletRequest request = new MockHttpServletRequest();
        MockHttpServletResponse response = new MockHttpServletResponse();
        request.addParameter("j_username", "gyanu");
        request.addParameter("j_password", "wrongpassword");
        LoginServlet login = new LoginServlet();
        login.setValid(false);
        login.doPost(request, response);
        assertEquals("/invalidlogin", response.getRedirectedUrl());
    }
}

我在 行上出错

如下：

回答：

我需要使用javax.selvlet-api替换javaee-api的依赖项，如下所示：

<dependency>
  <groupId>javax.servlet</groupId>
  <artifactId>javax.servlet-api</artifactId>
  <version>3.1.0</version>
</dependency>
