JUnit get() 方法在 Spring Boot 中不起作用

Question

我正在尝试在 Spring Boot 中使用 Junit 测试作为练习，但似乎 eclipse 或 IntelliJ IDEA 似乎无法识别连接测试方法中的 get、status 和 view 方法。每当我尝试运行控制台时，控制台都会抛出一个 java: '{' 。有没有办法解决这个错误？

package ca.sheridancollege.giljon.h2DemoWeek4;


import org.junit.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.test.context.junit4.SpringRunner;
import org.springframework.test.web.servlet.MockMvc;

@RunWith(SpringRunner.class)
@SpringBootTest
@AutoConfigureMockMvc
public class TestController(){

    @Autowired
    private MockMvc mockMvc;

    @Test
    public void testLoadingAddDrinkPage() throws Exception {
        this.mockMvc.perform(get("/")) .andExpect(status().isOk()).andExpect(view().name("add.html"));
    }
}

这是控制器类

package ca.sheridancollege.giljon.h2DemoWeek4.controller;

import ca.sheridancollege.giljon.h2DemoWeek4.beans.Drink;
import ca.sheridancollege.giljon.h2DemoWeek4.database.DatabaseAccess;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.*;

@Controller
public class DrinkController {
    @Autowired
    private DatabaseAccess da;

    @GetMapping("/")
    public String goHome(){
        return "home";
    }

    @GetMapping("/view.html")
    public String goViewData(Model model){
        model.addAttribute("drinks", da.getDrinks());
        return "view";
    }

    @GetMapping("/add.html")
    public String handleAddPage(Model model){
        model.addAttribute("drink", new Drink());
        return "add";
    }
    

    @GetMapping("/home.html")
    public String processAdd(Model model, @ModelAttribute Drink drink){
        da.addDrink(drink);
        model.addAttribute("drink", new Drink());
        return "home";
    }

    @GetMapping("/editLink/{id}")
    public String editLink(Model model, @PathVariable int id){
        Drink d = da.getDrinkById(id);
        model.addAttribute("drink", d);
        //in the database, the id 1. the reference without adding 1 is 0, resulting null
        return "modify";
    }

    @GetMapping("/deleteLink/{id}")
    public String deleteLink(@PathVariable int id, Model model){
        da.deleteDrink(id);
        model.addAttribute("myDrinks", da.getDrinks());
        return "redirect:/home.html";
    }

    @GetMapping("/modify")
    public String editDrink(Model model, @ModelAttribute Drink drink){
        da.editDrink(drink);
        return "redirect:/home.html";
    }

}

Answer 1

你的类声明中不应该有 '()'：

@RunWith(SpringRunner.class)
@SpringBootTest
@AutoConfigureMockMvc
public class TestController(){

应该是

@RunWith(SpringRunner.class)
@SpringBootTest
@AutoConfigureMockMvc
public class TestController {
