java – 找不到媒体类型= application / json的MessageBodyWrite

下面我添加了我的代码.

这是我的服务类：

//Sets the path to base URL + /hello
@Path("/hello") 
@Consumes(MediaType.APPLICATION_JSON)
@Produces(MediaType.APPLICATION_JSON)
public class Hello {

    @GET
    @Produces("application/json")
    public Student getStudent() {

        Student s = new Student();
        s.first_name = "Test First Name !!!";
        s.last_name = "Test Last Name!!!";

        return s;
    }

我想从服务中获得的学生班：

@XmlRootElement
public class Student implements Serializable {

    public String first_name;
    public String last_name;

    public String getFirst_name() {
        return first_name;
    }

    public void setFirst_name(String first_name) {
        this.first_name = first_name;
    }

    public String getLast_name() {
        return last_name;
    }

    public void setLast_name(String last_name) {
        this.last_name = last_name;
    }

    public Student()
    {
        first_name = "Fahad";
        last_name = "Mullaji";
    }
}

服务端的Web XML.

</web-app>

我不知道如何解决这个问题.
我正在使用SOAP UI来测试JSON响应,但我想这应该没关系.

我读过很多地方,我需要在下面添加代码.但我不知道在哪里.我没有使用Maven进行构建.

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

服务器正在寻找将Student对象解析为JSON的函数,但它无法为其找到函数或jar文件.
我已经添加了Genson,Moxy,RESTEasy和Jackson的jar,但我认为这就是问题所在.
我想我在某个地方缺少地图.
