我很难接受JSON输入到Spring Restful Webservice中.基本上我的目的是接受一个JSON并返回一个zip文件.但我无法跨越自己的第一步.
以下是控制器代码

@Controller
@RequestMapping(value = "/request")
public class PasskitController {

@Autowired
@Qualifier("PassManager")
private PassManager pm;

/*headers = { "Accept:application/json" },consumes = MediaType.APPLICATION_JSON_VALUE,*/

@RequestMapping(value = "/createPass",method = RequestMethod.POST,produces = MediaType.APPLICATION_OCTET_STREAM_VALUE)
public @ResponseBody ByteArrayOutputStream createGiftPass(
        @RequestBody PassGenerationRequest request) throws IOException {
    System.out.println("in createGiftPass() method");
    String success = "Success";
    ByteArrayOutputStream baos = new ByteArrayOutputStream();
    baos.write(success.getBytes());
    return baos;
}

@RequestMapping(value = "/test",method = RequestMethod.GET,produces = MediaType.TEXT_PLAIN_VALUE)
public @ResponseBody
String test() throws IOException {
    System.out.println("in test() method");
    return "Success";
}
}

我需要将输入JSON映射到以下pojo PassGenerationRequest

@JsonAutoDetect
public class PassGenerationRequest {

private String serialNumber;
private String upc;
private String campaign;
private String merchant;

public String getSerialNumber() {
    return serialNumber;
}

public void setSerialNumber(String serialNumber) {
    this.serialNumber = serialNumber;
}

public String getUpc() {
    return upc;
}

public void setUpc(String upc) {
    this.upc = upc;
}

public String getCampaign() {
    return campaign;
}

public void setCampaign(String campaign) {
    this.campaign = campaign;
}

public String getMerchant() {
    return merchant;
}

public void setMerchant(String merchant) {
    this.merchant = merchant;
}
}
