Spring MVC错误：此请求标识的资源只能生成响应 [英] Spring MVC error: The resource identified by this request is only capable of generating responses

问题描述

当我在浏览器中调用此URL时：

When I invoke this URL in the browser:

http://localhost:8080/app/foo.json

Spring在此错误消息中回复406状态代码：

Spring responds with 406 Status code in this error message:

此请求标识的资源只能根据请求accept标题（）生成具有不可接受特征的响应。

The resource identified by this request is only capable of generating responses with characteristics not acceptable according to the request "accept" headers ().

但是我已经定义了我的内容协商视图解析器，如下所示：

However I have defined my content negotiating view resolver like this:

<bean class="org.springframework.web.servlet.view.ContentNegotiatingViewResolver">
    <property name="favorPathExtension" value="true" />
    <property name="ignoreAcceptHeader" value="true" />

    <property name="mediaTypes">
        <map>
            <entry key="json" value="application/json"/>
            <entry key="html" value="text/html"/>
        </map>
    </property>
</bean>

我的控制器定义如下：

@Controller
@RequestMapping(value = "/foo")
public class ToowootController {

    @RequestMapping(method = GET)
    @ResponseBody
    public FooDTO index() {
        // return fooDTO
    }

}

任何想法我做错了什么？

Any ideas what am I doing wrong?

推荐答案

看起来问题是我没有添加所有必要的依赖项，在这种情况下 jackson-mapper-asl 。我以为只添加 jackson-core-asl 就够了。

Looks like the problem was that I had not added all the necessary dependencies, in this case jackson-mapper-asl. I thought only adding jackson-core-asl would be enough.
