在尝试使用 获取我的响应时JSON，Spring 3.x我得到406 error“此请求标识的资源只能生成具有根据request“接受”标头 () 不可接受的特征的响应。
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

在此之后，我只需使用以下方式访问控制器：
http://domain/SpringWebProject/json/contest/abcd
我得到的响应是状态 406：“此请求标识的资源只能生成具有根据请求“接受”标头（）不可接受的特征的响应。”
我还尝试了另一种机制，通过访问它Javascript AJAX来确保我的请求标头具有application/JSON，但这导致了相同的状态 406 结果
$.getJSON('contest/abcd', function(data) {
console.log(data) }
这是我从浏览器捕获的请求标头：
