JSON POST Spring MVC Curl - 400错误请求

Question

这是我的curl方法请求映射到POJO失败的400：

CURL REQUEST：

curl -v -H "Accept: application/json" -H "Content-type: application/json" -X POST -d     '{"key":"XYZ","uniqueId":"ABCD"}' http://localhost:8080/api/rest/connect/tick/view.json

APPLICATION-CONFIG.XML：

<context:annotation-config/>
<mvc:annotation-driven/>
followed by, Bean Definitions

控制器类：

@RequestMapping(value="/tick/view.*", method = RequestMethod.POST, consumes=MediaType.APPLICATION_JSON_VALUE, produces=MediaType.APPLICATION_JSON_VALUE)
@ResponseBody
    public IConnectResponse tickConnectPost(@RequestBody final ConnectServiceBean     connectServiceBean) {

CONNECTSERVICEBEAN：

import java.io.Serializable;
public class ConnectServiceBean implements Serializable {
    private static final long serialVersionUID = 1L;
    private String key;
    private String uniqueId;
    //Getters and setters }

但是正在为另一个方法请求映射到String：

curl -i -H "Content-Type: application/json" -X POST -d '{"JKL@user.com"}'     http://localhost:8080/api/rest/connect/tick/XYZ/view.json
HTTP/1.1 200 OK

控制器：

@RequestMapping(value="/tick/{key}/view.*", method = RequestMethod.POST,      consumes="application/json", produces = "application/json; charset=utf-8")
    public IConnectResponse tickConnectPostString (
        @PathVariable("key") String key, @RequestBody String uniqueId
    ) {}

我觉得Jackson Mapping有问题。但我有所有必要的POM依赖项，我在其他一些stackoverflow文章中读到，我只需要针对bean映射的Jackson配置（不确定）                                      org.codehaus.jackson                 杰克逊核心-ASL                 1.9.7
