Postman测试http请求返回415状态码的解决

首先记录一下返回结果

HTTP Status 415 – Unsupported Media Type
Type Status Report
Message Unsupported Media Type
Description The origin server is refusing to service the request because the payload is in a format not supported by this method on the target resource.

Apache Tomcat/8.0.53

postman参数如下图

 使用https请求并携带一组formData向eclipse后台请求数据，结果返回状态码415

415状态码

Unsupported Media Type

服务器无法处理请求附带的媒体格式

处理该请求的源码是：

@POST
	@Path("calc")
	@Produces(MediaType.APPLICATION_JSON)
	@Consumes({MediaType.APPLICATION_XHTML_XML,MediaType.APPLICATION_XML/*,MediaType.APPLICATION_FORM_URLENCODED*/})
	public String getCalculationResult(@FormParam("num1") String num1, @FormParam("num2")String num2){
		Result r = new Result().success();
		r.setData(NumberUtils.toInt(num1)+NumberUtils.toInt(num2));
		return r.toString();
	}

执行该方法时的日志记录

可以看到，该条请求的 content-type: application/x-www-form-urlencoded，@Consumes的参数列表中没有此种类型的变量，即表示该资源不接受此种content-type的请求。(使用的RESTful 风格的jersey框架)，增加这种请求媒体类型的支持即可，即去掉源码上@Consumes的标签注释即可解决。
