c，编写好控制类的代码，我们可以测试这个控制类了，下面的代码是使用TestNg测试controller十分正确
package test.com.smart.web;
import com.smart.domain.User;
import com.smart.web.LoginController;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.mock.web.MockHttpServletRequest;
import org.springframework.mock.web.MockHttpServletResponse;
import org.springframework.test.context.ContextConfiguration;
import org.springframework.test.context.testng.AbstractTestNGSpringContextTests;
import org.springframework.test.util.ReflectionTestUtils;
import org.springframework.web.client.RestTemplate;
import org.springframework.web.servlet.HandlerMapping;
import org.springframework.web.servlet.ModelAndView;
import org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter;
import org.testng.annotations.BeforeMethod;
import org.testng.annotations.Test;
import static org.testng.Assert.assertEquals;
import static org.testng.Assert.assertNotNull;
import static org.testng.Assert.assertNull;
@ContextConfiguration(locations = {"classpath:applicationContext.xml"，"file:d:/actionSpring/chapter/chapter1/src/main/webapp/WEB-INF/viewspace-servlet.xml"})
public class LoginControllerTest extends AbstractTestNGSpringContextTests {
@Autowired
private AnnotationMethodHandlerAdapter handlerAdapter;
@Autowired
private LoginController controller;
//声明Request与Response模拟对象
private MockHttpServletRequest request;
private MockHttpServletResponse response;
//执行测试前先初始模拟对象
@BeforeMethod
public void before() {
request = new MockHttpServletRequest();
request.setCharacterEncoding("UTF-8");
response = new MockHttpServletResponse();
request.setAttribute(HandlerMapping.INTROSPECT_TYPE_LEVEL_MAPPING， true); //Spring3.1 存在的BUG
}
// 测试LoginController#loginCheck()方法
@Test
public void loginCheck() throws Exception {
//测试登陆成功的情况
request.setRequestURI("/admin/loginCheck.html");
request.addParameter("userName"， "admin"); // 设置请求URL及参数
request.addParameter("password"， "123456");
//向控制发起请求 ” /loginCheck.html”
ModelAndView mav = handlerAdapter.handle(request， response， controller);
User user = (User) request.getSession().getAttribute("user");
assertNotNull(mav);
assertEquals(mav.getViewName()， "main");
assertNotNull(user);
request.getSession().removeAttribute("user");
//测试登陆失败的情况
request.setRequestURI("/admin/loginCheck.html");
request.addParameter("userName"， "test");
request.addParameter("password"， "123456");
mav = handlerAdapter.handle(request， response， controller);
user = (User) request.getSession().getAttribute("user");
assertNotNull(mav);
assertEquals(mav.getViewName()， "login");
assertNull(user);
}
}
　　注意：
@ContextConfiguration(locations = {"classpath:applicationContext.xml"，"file:d:/actionSpring/chapter/chapter1/src/main/webapp/WEB-INF/viewspace-servlet.xml"})  这个注解可以整合多个spring配置文件中"file:d:/actionSpring/chapter/chapter1/src/main/webapp/WEB-INF/viewspace-servlet.xml"表示的是文件系统的形式给出配置文件
