MockMVC在SpringTest中返回404和pageNotFound警告

Question

过去一周我一直在研究，无法找到解释为什么我的springMVC中的测试用例会抛出404.它会记录一个警告，指出找不到页面。我非常确定我的配置是正确的并且加载了应用程序上下文。为什么mockMvc没有执行请求并返回200状态等？

这是我的Test类：

    package com.fdmgroup.issuetracker.controller;

import static org.junit.Assert.*;

import org.junit.After;
import org.junit.Before;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.test.web.servlet.MockMvc;
import org.springframework.test.web.servlet.MockMvcBuilder;
import org.springframework.test.web.servlet.setup.MockMvcBuilders;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.test.context.ContextConfiguration;
import org.springframework.test.context.TestContext;
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;
import org.springframework.test.context.web.WebAppConfiguration;
import org.springframework.web.context.WebApplicationContext;
import org.springframework.web.servlet.view.InternalResourceViewResolver;

import com.fdmgroup.issuetracker.model.impl.User;

import static org.springframework.test.web.servlet.request.MockMvcRequestBuilders.*;
import static org.springframework.test.web.servlet.result.MockMvcResultMatchers.*;
import static org.springframework.test.web.servlet.setup.MockMvcBuilders.*;
@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration("classpath:*/test-context.xml")
@WebAppConfiguration
public class LoginControllerTest {
    @Autowired
    private WebApplicationContext wac;

    private MockMvc mockMvc;
    private User user;
    @Before
    public void setUp() throws Exception {


        this.mockMvc = MockMvcBuilders.webAppContextSetup(this.wac).build();

    }

    @After
    public void tearDown() throws Exception {
    }

    @Test
    public void testIfDisplayLoginPageReturnsLoginJsp() throws Exception {
    mockMvc.perform(get("/login")).andExpect(status().isOk());
    }

    @Test
    public void testLoginServlet() throws Exception {
    String username = "Corey";
    String password = "Password";

        mockMvc.perform(post("/LoginServlet").param("username", username).param("password", password)).andExpect(status().isOk());
    }

}

跟踪控制台的跟踪记录：

如果需要其他任何东西来分析问题，请告诉我。

Answer 1

尝试在测试类上方添加此注释

@ContextConfiguration(classes = <YourController>.class)
public class ControllerTest {

Answer 2

答案在于你所包含的堆栈跟踪

12:27:00  WARN [main] - org.springframework.web.servlet.PageNotFound.noHandlerFound - No mapping found for HTTP request with URI [/login] in DispatcherServlet with name ''

因此，您没有注册处理/login请求路径的控制器。

您需要包含Spring MVC的XML配置文件才能使测试正常运行。
