找不到媒体类型= application / json的MessageBodyWriter - 使用MAVEN

Question

嗨，我正在努力解决这个错误。我有我的apimanager

    public static ProfileEntity createUser(UserEntity userEntity) {

    // userEntity - userRequestModel
    UserRequestModel uRequestModel = InterviewerMapper.convertRequest(userEntity,MapperImplementation::convertRequest);

    try {

        WebTarget Client = ClientBuilder.newClient().target("http://localhost:8080/messenger/webapp");
        Entity entity = Entity.entity(uRequestModel, MediaType.APPLICATION_JSON);
        Response response = Client.path("/interview/users").request().post(entity);

        UserResponseModel userResponseModel = response.readEntity(UserResponseModel.class);

        ProfileEntity pEntity = InterviewerMapper.convertProfile(userResponseModel, e -> {
            try {
                return MapperImplementation.convertProfile(e);
            } catch (Exception e1) {
                // TODO Auto-generated catch block
                e1.printStackTrace();
            }
            return null;
        });

        return pEntity;

    } catch (Exception e) {

        e.printStackTrace();

    } 
    return null;

}

我的资源：

    @POST
@Path("/users")
@Produces(MediaType.APPLICATION_JSON)
public UserResponseModel createUser(UserRequestModel userRequest) {

    Random rand = new Random();
    int  userId = rand.nextInt(50) + 1;

    // insert into database and retrieve the userId


    UserResponseModel uResponseModel = new UserResponseModel(userRequest.getFirstName(), userRequest.getLastName(), userRequest.getCountry(), userRequest.getUserName(), userRequest.getPassWord(), userId , generateAuthToken(), new Date());

    return uResponseModel;
}

和我的web.xml

这是我的请求类

package ca.ciccc.madp202.messenger.model;

import javax.xml.bind.annotation.XmlRootElement;

@XmlRootElement
public class UserRequestModel {
       private String firstName;
        private String lastName;

        public UserRequestModel() {

        }

        public UserRequestModel(String firstName, String lastName, String country, String userName, String passWord) {
            this.firstName = firstName;
            this.lastName = lastName;
            this.country = country;
            this.userName = userName;
            this.passWord = passWord;
        }

        public String getFirstName() {
            return firstName;
        }

        public void setFirstName(String firstName) {

        }

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

        public String getCountry() {
            return country;
        }

        public void setCountry(String country) {
            this.country = country;
        }

        public String getUserName() {

我用Google搜索了问题，大多数解决方案都是添加此依赖项

        <dependency>
        <groupId>org.glassfish.jersey.media</groupId>
        <artifactId>jersey-media-moxy</artifactId>
        <version>2.25.1</version>
    </dependency>

但我已经拥有它了。我不知道出了什么问题。有人可以帮帮我吗？ 我已经用邮递员测试了我的资源文件，看看我是否得到了任何响应并且它正在工作; Link to postman
