Question

当我在游戏2.1中执行控制器测试时遇到一些奇怪的问题。

    package controllers;

import static org.fest.assertions.Assertions.assertThat;
import static play.mvc.Http.Status.OK;
import static play.test.Helpers.callAction;
import static play.test.Helpers.charset;
import static play.test.Helpers.contentType;
import static play.test.Helpers.status;

import models.Section;
import models.Topic;

import org.junit.Test;

import play.mvc.Result;

public class TopicsTest extends BaseControllerTest{
    @Test
    public void testCallList() {
        Section s = new Section();
        s.name = "Music section";
        s.id = 1L;
        s.description = "section about music";
        s.save();
        System.out.println(Section.find.where().eq("name", "Music section").findUnique().id); // output 1
        Result result = callAction(controllers.routes.ref.Topics.list(1));
        assertThat(status(result)).isEqualTo(OK);
    }
}

控制器代码非常简单，适用于开发人员。模式很好。检查一下：

public static Result list(Long id) {
    return ok(list.render(Section.find.byId(id)));
}

错误堆栈跟踪：

请帮我找到解决方案，或假冒这个测试。

Play似乎无法访问模型类的字段（看起来它不会生成getter和setter）。然后，相当明显的解决方案是明确地编写自己的getter（和setter），这样无论如何Play都可以找到它们。
