测试过程

• RestfulApplicationTests.java

package com.antrain.restful;import com.antrain.restful.controller.UserController;import org.junit.jupiter.api.Test;import org.junit.runner.RunWith;import org.springframework.beans.factory.annotation.Autowired;import org.springframework.boot.test.autoconfigure.web.servlet.AutoConfigureMockMvc;import org.springframework.boot.test.context.SpringBootTest;import org.springframework.boot.test.mock.mockito.MockBean;import org.springframework.test.context.junit4.SpringRunner;import org.springframework.test.web.servlet.MockMvc;import org.springframework.test.web.servlet.request.MockMvcRequestBuilders;import org.springframework.transaction.annotation.Transactional;import org.springframework.util.LinkedMultiValueMap;import org.springframework.util.MultiValueMap;@RunWith(SpringRunner.class)@SpringBootTest@Transactional@AutoConfigureMockMvcclass RestfulApplicationTests {
       @Autowired    private MockMvc mockMvc;    @MockBean    private UserController userController;    /**     * 1、mockMvc.perform执行一个请求。     * 2、MockMvcRequestBuilders.get("XXX")构造一个请求。     * 3、ResultActions.param添加请求传值     * 4、ResultActions.accept(MediaType.TEXT_HTML_VALUE))设置返回类型     * 5、ResultActions.andExpect添加执行完成后的断言。     * 6、ResultActions.andDo添加一个结果处理器，表示要对结果做点什么事情     * 比如此处使用MockMvcResultHandlers.print()输出整个响应结果信息。     * 5、ResultActions.andReturn表示执行完成后返回相应的结果。     */    @Test    public void loginTest() throws Exception {
           MultiValueMap
   
     params = new LinkedMultiValueMap<>();        params.add("userName", "admin");        params.add("password", "admin");        if (mockMvc == null) {
               System.out.println("程序出错....");            return;        }        String msg = mockMvc.perform(MockMvcRequestBuilders.post("/admin/login")                .params(params)).andReturn().getResponse().getContentAsString();        System.out.println(msg.length());//0        System.out.println(msg);    }}
   

测试controller

• 测试UserController
  其他Java类参考

package com.antrain.restful.controller;import com.antrain.restful.entity.User;import com.antrain.restful.service.UserService;import org.springframework.stereotype.Controller;import org.springframework.ui.Model;import org.springframework.web.bind.annotation.*;import javax.annotation.Resource;@Controller@RequestMapping("/admin")public class UserController {
       @Resource    private UserService userService;    @GetMapping("/users")    public String list(Model model){
           model.addAttribute("users",userService.queryAll());        return "admin/list";    }    @GetMapping("/user")    public  String toAdd(Model model){
           return "admin/add";    }    @PostMapping("/user")    public String add(User user){
           System.out.println("传入参数：==="+user);        userService.insert(user);        return "redirect:/admin/users";    }    @GetMapping("/user/{id}")    public String toEdit(@PathVariable("id") Integer id, Model model){
           model.addAttribute("user",userService.queryById(id));        return "admin/add";    }    @PutMapping("/user")    public String update(User user){
           System.out.println("传入参数：==="+user);        System.out.println("修改前数据库内容：===="+userService.queryById(user.getId()));        userService.update(user);        System.out.println("修改后数据库内容：===="+userService.queryById(user.getId()));        return "redirect:/admin/users";    }    @DeleteMapping("/user/{id}")    public String del(@PathVariable("id") Integer id){
           System.out.println("修改前数据库内容：===="+userService.queryById(id));        userService.del(id);        System.out.println("修改后数据库内容：===="+userService.queryById(id));        return "redirect:/admin/users";    }}

• 创建测试类
  
  
• 测试类UserControllerTest.java

问题日志

• Error running ‘RestfulApplicationTests.loginTest’: Failed to resolve org.junit.vintage:junit-vintage-engine:5.5.2
  移除依赖即可 注：可以在Diagrams移除较好
• 先注释掉SiteWebMvcConfigurer配置类的addInterceptors()方法
