JAX-RS Jersey - Howto force a Response ContentType? Overwrite content negotiation
提问by Joe
Jersey identifies requests by looking at the accept header. I have a request which accepts only text/* - How can i force the response to be for example application/json?
Jersey 通过查看接受标头来识别请求。我有一个只接受 text/* 的请求 - 我如何强制响应为例如 application/json？
@POST
@Path("/create")
@Produces(MediaType.APPLICATION_JSON)
public MyResponseObject create() {
return new MyResponseObject();
}
If a request is directed to create which only accepts text/* jersey will return a 500. Is there a way to workaround this issue? (I can't change the requests accept header).
如果请求创建只接受 text/* jersey 将返回 500。有没有办法解决这个问题？（我无法更改请求接受标头）。

Jersey also supports this via ResourceConfigproperty PROPERTY_MEDIA_TYPE_MAPPINGS that you could configure in your web.xml or programatically via Jersey APIs as shown below:
Jersey 还通过ResourceConfig属性 PROPERTY_MEDIA_TYPE_MAPPINGS支持此功能，您可以在 web.xml 中或通过 Jersey API 以编程方式进行配置，如下所示：
DefaultResourceConfig rc = new DefaultResourceConfig(MyResource.class);
rc.getMediaTypeMappings().put("json", MediaType.APPLICATION_JSON_TYPE);
rc.getMediaTypeMappings().put("xml", MediaType.APPLICATION_XML_TYPE);
SimpleServerFactory.create("http://localhost:9090", rc);
You can force content type negotiation by suffixing either .json or .xml to your URL.
您可以通过在 URL 后缀 .json 或 .xml 来强制内容类型协商。
