java - 415 POST 请求中不支持的媒体类型

Question

正在四处阅读，其他人遇到的很多问题都是 Spring、Gradle 或其他问题。 Postman 似乎不喜欢我对 POST 方法提出的请求。

错误:

b>description</b>
        <u>The server refused this request because the request entity is in a format not supported by the requested resource for the requested method (Unsupported Media Type).</u>

来自 Postman 的正文:

{
"firstName": "firstName",
"lastName": "lastName",
"dob": "12/12/2012",
"address": "123 main st."
}

有问题的帖子:

@POST
@Produces(MediaType.APPLICATION_JSON)
@Consumes(MediaType.APPLICATION_JSON)
@Path("/createQuery")
public Response createQuery(ApplicationInfo info) throws IOException {
    String queryString =createStringFromJSON(info,true);
    queryMap.put(""+countId,queryString);
    countId++;
    ObjectMapper objectMapper = new ObjectMapper();
    String json = "";
    try {
        json = objectMapper.writeValueAsString(queryMap);
    } catch (JsonProcessingException e) {
        e.printStackTrace();
    }        return Response.ok(json,MediaType.APPLICATION_JSON_TYPE).entity(json).build();
}

极其复杂的 ApplicationInfo 对象:

 public class ApplicationInfo

{
    String firstName;
    String lastName;
    String dob;
    String address;

    public String getFirstName() {
        return firstName;
    }

    public void setFirstName(String firstName) {
        this.firstName = firstName;
    }
public String getLastName() {
    return lastName;
}

public void setLastName(String lastName) {
    this.lastName = lastName;
}

public String getDob() {
    return dob;
}

public void setDob(String dob) {
    this.dob = dob;
}

public String getAddress() {
    return address;
}

public void setAddress(String address) {
    this.address = address;
}
}

希望更有经验的人可以查明问题所在。请保持它与我的问题相关。

您的请求正文似乎是有效的 json 字符串，只需验证您是否在 postman 应用程序中传递了正确的 header
header 看起来像

Accept:application/json
Content-Type:application/json
