Java 如何编写控制器类以允许内容类型:application/json和application/x-www-form-urlencoded
我将请求作为内容类型发送给我的控制器类请求:application/json和application/x-www-form-urlencoded格式,它应该允许这两种类型Java 如何编写控制器类以允许内容类型:application/json和application/x-www-form-urlencoded,java,json,spring,rest,Java,Json,Spring,Rest,我将请求作为内容类型发送给我的控制器类请求:application/json和application/x-www-form-urlencoded格式,它应该允许这两种类型 但是当我使用请求类型作为应用程序/x-www-form-urlencoded时,它正在工作,但当我使用请求应用程序/json时,该代码不工作,它给出400响应状态。如何解决此问题。您可以在@RequestMapping中定义consumes属性,并在xml中定义ViewResolver。 下: @RequestMappingc
但是当我使用请求类型作为应用程序/x-www-form-urlencoded时,它正在工作,但当我使用请求应用程序/json时,该代码不工作,它给出400响应状态。如何解决此问题。您可以在@RequestMapping中定义consumes属性,并在xml中定义ViewResolver。 下: @RequestMappingconsumes=[] 内容协商解决方案
您可以在@RequestMapping中定义consumes属性,在xml中定义ViewResolver。 下: @RequestMappingconsumes=[] 内容协商解决方案
您需要为请求的内容类型标头使用consumes注释元素,并为请求的Accept标头生成注释元素:
@RequestMapping(value = "/home",
method = RequestMethod.POST,
consumes = {"application/json", "application/x-www-form-urlencoded"},
produces = "application/json")
参考:
这些RequestMapping元素可用于Spring4。如果使用Spring 2,则需要使用params元素,而不是consumes&Products元素:
@RequestMapping(value = "/home",
method = RequestMethod.POST,
params = {"content-type=application/json",
"content-type=application/x-www-form-urlencoded",
"Accept=application/json"})

//Console.WriteLine("Registration Status Code: {0}", registerResult);
string token = GetToken(userName, password);
Console.WriteLine("");
Console.WriteLine("Access Token:");
Console.WriteLine(token);
Dictionary<string, string> tokenDic = GetTokenDictionary(token);
GetUserInfo(tokenDic["access_token"]);
}

我认为没有必要使用ViewResolver!只消耗注释元素就足够了。我认为没有必要使用ViewResolver!仅使用注释元素就足够了。为此,我们需要添加任何依赖项…?是的,Spring 4。*,我更新了关于您问题的答案。对于Spring 4,请遵循以下指南:为此,我们需要添加任何依赖项…?是的,Spring 4。*,我更新了关于您问题的答案。对于Spring 4,请遵循以下指南:
