三，java代码说明

1,controller/HomeController.java

@Controller
@RequestMapping("/home")
public class HomeController {

    //返回单个商品
    @GetMapping("/one")
    public String one(Model model) {
        Goods goods31 = new Goods();
        goods31.setGoodsId(31L);
        goods31.setGoodsName("纯色真丝睡袍");

        //把list传递给模板
        model.addAttribute("goodsOne",goods31);
        return "home/one.html";
    }

    //返回商品列表
    @GetMapping("/list")
    public String list(Model model) {

        ArrayList<Goods> listGoods1 = new ArrayList<Goods>();

        Goods goods1 = new Goods();
        goods1.setGoodsId(1L);
        goods1.setGoodsName("无线智能感应灯");
        listGoods1.add(goods1);
        Goods goods2 = new Goods();
        goods2.setGoodsId(2L);
        goods2.setGoodsName("朱之光落地灯");
        listGoods1.add(goods2);
        Goods goods3 = new Goods();
        goods3.setGoodsId(3L);
        goods3.setGoodsName("儿童抗首菌枕头");
        listGoods1.add(goods3);
        //把list传递给模板
        model.addAttribute("list",listGoods1);
        return "home/list.html";
    }
}

2,pojo/Goods.java

//商品模型
public class Goods {
    //商品id
    Long goodsId;
    public Long getGoodsId() {
        return this.goodsId;
    }
    public void setGoodsId(Long goodsId) {
        this.goodsId = goodsId;
    }

    //商品名称
    private String goodsName;
    public String getGoodsName() {
        return this.goodsName;
    }
    public void setGoodsName(String goodsName) {
        this.goodsName = goodsName;
    }

    //商品标题
    private String subject;
    public String getSubject() {
        return this.subject;
    }
    public void setSubject(String subject) {
        this.subject = subject;
    }

    //商品价格
    private BigDecimal price;
    public BigDecimal getPrice() {
        return this.price;
    }
    public void setPrice(BigDecimal price) {
        this.price = price;
    }

    //库存
    int stock;
    public int getStock() {
        return this.stock;
    }
    public void setStock(int stock) {
        this.stock = stock;
    }

    //打印
    @Override
    public String toString(){
        return " Goods:goodsId=" + goodsId +" goodsName=" + goodsName+" subject=" + subject+" price=" + price+" stock=" + stock;
    }
}

3,controller/HomeControllerTest.java

@AutoConfigureMockMvc
@SpringBootTest
class HomeControllerTest {
    @Autowired
    private MockMvc mockMvc;

    @Test
    @DisplayName("测试显示单个商品")
    void one() throws Exception {
        ModelAndView mv=mockMvc.perform(get("/home/one"))
                .andExpect(status().isOk())
                .andReturn().getModelAndView();
        //view
        String viewName=mv.getViewName();
        assertThat(viewName,equalTo("home/one.html"));
        //model
        Goods goods = (Goods)mv.getModel().get("goodsOne");
        assertThat(goods.getGoodsId(),equalTo(31L));
        assertThat(goods.getGoodsName(),equalTo("纯色真丝睡袍"));

    }

    @Test
    @DisplayName("测试显示商品列表")
    void list() throws Exception {
        ModelAndView mv=mockMvc.perform(get("/home/list"))
                .andExpect(status().isOk())
                .andReturn().getModelAndView();
        //view
        String viewName=mv.getViewName();
        assertThat(viewName,equalTo("home/list.html"));


        Map<String, Object> model = mv.getModel();
        ArrayList<Goods> list = (ArrayList) model.get("list");
        //检查列表数量
        assertThat(list.size(),greaterThan(0));
        //检查第一个商品的id
        Goods one = list.get(0);
        assertThat(one.getGoodsId(),greaterThan(0L));
    }
}
