在尝试获得JSON使用的响应时Spring 3.x，我得到了406 error“此请求标识的资源只能根据request“
accept”标头（）生成特性不可接受的响应”。

这是我的环境

* Spring 3.2.0.RELEASE
* included jackson-mapper-asl-1.7.9.jar, jackson-core-asl-1.7.9.jar
* Tomcat 6.x
* mvc:annotation-driven in Spring configuration XML file

我的控制器：

@RequestMapping("/contest")
public class ContestController {

    @RequestMapping(value="{name}", headers="Accept=*/*", method = RequestMethod.GET)
    public @ResponseBody Contest getContestInJSON(@PathVariable String name) {
        Contest contest = new Contest();
        contest.setName(name);
        contest.setStaffName(new String("contestitem1"));

        return contest;
    }

}

我的Spring配置文件

<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:context="http://www.springframework.org/schema/context"
xmlns:mvc="http://www.springframework.org/schema/mvc" 
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

      <entry key="atom" value="application/atom+xml"/>

 </property>

 <property name="defaultViews">
  <list>
   <bean class="org.springframework.web.servlet.view.json.MappingJacksonJsonView" />
  </list>
 </property>

 </bean>

<mvc:annotation-driven />

</beans>

在此之后，我只需使用以下命令访问控制器：

http://domain/SpringWebProject/json/contest/abcd

并且我得到的响应是状态406：“此请求标识的资源只能根据请求“接受”标头（）生成特性不可接受的响应。”

我还尝试通过使用Javascript
AJAX来确保使用我的请求标头访问此方法的替代机制，application/JSON但这导致了相同的Status 406结果

$.getJSON('contest/abcd', function(data) {
console.log(data) }

这是从浏览器捕获的我的请求头：

Request Method:GET
