使用 MockMvc 在 Spring MVC 中进行单元测试/登录

我有一个使用 Spring MVC 创建的非常简单的 REST 应用程序。 （代码可在GitHub.）它有一个简单的WebSecurityConfigurer如下：

@Override
protected void configure(HttpSecurity httpSecurity) throws Exception {
    httpSecurity
            .csrf().disable()
            .exceptionHandling()
                .authenticationEntryPoint(authenticationEntryPoint)
                .and()
            .authorizeRequests()
                .antMatchers("/user/new").permitAll()
                .anyRequest().authenticated()
                .and()
            .formLogin()
                .loginPage("/login").permitAll()
                .successHandler(authenticationSuccessHandler)
                .failureHandler(authenticationFailureHandler)
                .and()
            .logout()
                .permitAll()
                .logoutSuccessHandler(logoutSuccessHandler);
}

当我运行该应用程序时，自定义控制器和登录/注销页面都可以正常工作。我什至可以单元测试 /user/new via MockMvc。但是，当我尝试测试时/login具有以下功能

@Test
public void testUserLogin() throws Exception {
    RequestBuilder requestBuilder = post("/login")
            .param("username", testUser.getUsername())
            .param("password", testUser.getPassword());
    mockMvc.perform(requestBuilder)
            .andDo(print())
            .andExpect(status().isOk())
            .andExpect(cookie().exists("JSESSIONID"));
}

它失败如下：

MockHttpServletRequest:
         HTTP Method = POST
         Request URI = /login
          Parameters = {username=[test-user-UserControllerTest], password=[test-user-UserControllerTest-password]}
             Headers = {}

             Handler:
                Type = org.springframework.web.servlet.resource.ResourceHttpRequestHandler

               Async:
   Was async started = false
        Async result = null

  Resolved Exception:
                Type = org.springframework.web.HttpRequestMethodNotSupportedException

        ModelAndView:
           View name = null
                View = null
               Model = null

            FlashMap:

MockHttpServletResponse:
              Status = 405
       Error message = Request method 'POST' not supported
             Headers = {Allow=[HEAD, GET]}
        Content type = null
                Body = 
       Forwarded URL = null
      Redirected URL = null
             Cookies = []

java.lang.AssertionError: Status expected:<200> but was:<405>

但我是相当用户POST to /login当我运行应用程序而不是测试时正在工作。此外，当我尝试制作一个GET or HEAD请求（如建议的Headers = {Allow=[HEAD, GET]}日志行），这次我收到 404。关于发生了什么以及如何修复它有什么想法吗？

您可以使用 Spring 安全测试类来测试基于表单的登录。您需要执行以下操作来测试基于表单的登录。

Maven 依赖：

<dependency>
    <groupId>org.springframework.security</groupId>
    <artifactId>spring-security-test</artifactId>
    <version>4.0.0.M1</version>
    <scope>test</scope>
</dependency>

<repositories>
    <repository>
        <id>spring-snasphot</id>
        <url>https://repo.spring.io/libs-snapshot</url>
    </repository>
</repositories>

测试类：

import static org.springframework.security.test.web.servlet.request.SecurityMockMvcRequestBuilders.formLogin;

RequestBuilder requestBuilder = formLogin().user("username").password("passowrd");
mockMvc.perform(requestBuilder)
    .andDo(print())
    .andExpect(status().isOk())
    .andExpect(cookie().exists("JSESSIONID"));
