如何在Spring 4中使用rapidxml Jackson JSON序列化 [英] How to use fasterxml Jackson JSON serialization in Spring 4
问题描述
当我使用以下curl调用它时，为什么我的Spring控制器不返回媒体类型 application / json ：
Why doesn't my Spring controller return media type application/json when I call it with the following curl:
curl -v -i -H "Accept: application/json" localhost:8080/properties-ws/prop/2322
我已经阅读了有关此主题的所有其他问题和答案，没有解决我的具体问题。
I've read all other questions and responses on this subject and none address my specific issue.
我正在使用Spring 4，并且有一个简单的Controller和pom。
I'm using Spring 4, and have a simple Controller and pom.
控制器方法
@RequestMapping(value="/prop/{character}",
method=RequestMethod.GET,
produces={MediaType.APPLICATION_JSON_VALUE})
public @ResponseBody CharData getData(@PathVariable(value="character") int codePoint) {
CharData chData = null;
chData = CharPropertiesService.getProperties(codePoint);
return chData;
}
依赖杰克逊的POM文件
我包括了fastxml jackson-databind工具版本2.3.3
I included the fasterxml jackson-databind artifact version 2.3.3
这是pom：

控制器返回HTTP响应406并显示一条消息：
The controller returns HTTP response 406 with a 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.
关于我没有正确配置的任何想法？
Any ideas about where I'm not configuring this properly?
推荐答案
感谢Sotirios，我已经解决了我的问题。我不确定为什么这会解决它，但确实如此。
Thanks to Sotirios, I've resolved my issue. I'm not sure why this resolved it, but it did.
我只是将以下内容放在我的servlet-context.xml中：
I simply put the following in my servlet-context.xml:
<mvc:annotation-driven/>
就是这样。这就是全部，现在Spring返回了我期望的对象的JSON表示。
That's it. That's all it took, and now Spring is returning the JSON representation of object that I expected.
