请放心-预期的内容类型“JSON”与实际的内容类型“”不匹配

Question

在我的rest控制器类中，我有以下方法

@RequestMapping(value = "/film", method = RequestMethod.GET, produces = "application/json")
public Film getFilm(@RequestParam("search") String filmSearch){
    FilmDomain filmDomain = new FilmDomain();
    Film film = filmDomain.getCurrentFilm(filmSearch);
    return film;
}

这特别说明我正在将application/json对象返回给请求用户。但是，当我执行rest-assured测试时

@Test
public void test_specified_film_is_retrieved(){
    given().when().get("/view/film?search=The%20Godfather").then().contentType(ContentType.JSON).body("filmTitle", equalTo("The Godfather"));
}

我收到以下错误

java.lang.AssertionError: 1 expectation failed.
Expected content-type "JSON" doesn't match actual content-type "".

我很困惑，不知道为什么我的标题在rest测试中没有说明任何内容类型。我将请求放入我的web浏览器并选择Headers选项卡，元数据如下所示

响应头

Content-Type    application/json;charset=UTF-8
Date    Wed, 17 Jan 2018 10:09:14 GMT
Transfer-Encoding   chunked

请求头

Accept  text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8
Accept-Encoding gzip, deflate
Accept-Language en-GB,en;q=0.5
Connection  keep-alive
Cookie  jenkins-timestamper-offset=0
Host    localhost:8080
Upgrade-Insecure-Requests   1
User-Agent  Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:57.0)     Gecko/20100101 Firefox/57.0

关于为什么我的ContentType没有被请求的rest-assured测试看到，有什么想法吗？

Answer 1

在接受内容格式中使用application/json，而不是

接受text/html、application/xhtml、application/xml；q=0.9，/；q=0.8

Answer 2

替换ContentType。JSON由“application/JSON\r\n”编写。换行和回车不能通过重启来区分，我必须在上一个项目中这样做才能使它工作。
