JavaSpringRequestMapping测试代码不起作用

Question

我正在学习Spring5，我不能使用@RequestMapping注释，也不知道为什么

@RequestMapping包含@Component注释，所以我想我可以使用它

initRequest按字符串包含URL参数

我只是希望initRequest（/hello）参数绑定URL

这是我的密码

public class SimpleControllerTest extends AbstractDispatcherServletTest {
@Test
public void helloSimpleController() throws ServletException, IOException {
    setClasses(HelloController.class);
    initRequest("/hello").addParameter("name", "spring");
    runService();
    assertModel("message", "Hello spring");
    assertViewName("/WEB-INF/view/hello.jsp");
}

@Test(expected=Exception.class)
public void noParameterHelloSimpleController() throws ServletException, IOException {
    setClasses(HelloController.class);
    initRequest("/hello");
    runService();
}

@Component("/hello")
//@RequestMapping("/hello")
static class HelloController extends SimpleController {
    public HelloController() {
        this.setRequiredParams(new String[] {"name"});
        this.setViewName("/WEB-INF/view/hello.jsp");
    }

    public void control(Map<String, String> params, Map<String, Object> model) throws Exception {
        model.put("message", "Hello " + params.get("name"));
    }
}

static abstract class SimpleController implements Controller {
    private String[] requiredParams;
    private String viewName;

    public void setRequiredParams(String[] requiredParams) {
        this.requiredParams = requiredParams;
    }

    public void setViewName(String viewName) {
        this.viewName = viewName;
    }

    final public ModelAndView handleRequest(HttpServletRequest req,
                                            HttpServletResponse res) throws Exception {
        ...
    }


    public abstract void control(Map<String, String> params, Map<String, Object> model) throws Exception;
}

}
