无法通过Topic.id的反射getter获取字段值

Question

您好，我有一个与Maven和Jboss的RSSFEED知道我尝试将主题添加到新闻源但我收到此错误：

我尝试使用我的Topic.java和News.Java进行@ManytoMany

import java.io.Serializable;
import java.util.ArrayList;
import java.util.List;

import javax.persistence.*;



@Table(name = "Topic")
@Entity
public class Topic implements Serializable {

    private static final long serialVersionUID = 1L;
    @Id
    @GeneratedValue(strategy = GenerationType.AUTO, generator="seq_topic")
    @SequenceGenerator(name="seq_topic", sequenceName="seq_topic", allocationSize=1)
    private int id;
    private String name;
    public int getId() {
        return id;
    }
    @ManyToMany (fetch = FetchType.EAGER, mappedBy = "topic")
    private List<News> News = new ArrayList<>();

    public List<News> getNews() {
        return News;
    }

    public void setNews(List<News> news) {
        News = news;
    }

    public void setId(int id) {
        this.id = id;
    }
    public Topic(){

    }
    public Topic(String name){
        this.name =name;
    }


    public String getName() {
        return name;
    }

    public void setName(String name) {
        name = name;
    }
    @Override
    public String toString() {
        return name;
    }

    @Override
    public int hashCode() {
        final int prime = 31;
        int result = 1;
        result = prime * result + id;
        result = prime * result + ((name == null) ? 0 : name.hashCode());
        return result;
    }

    @Override
    public boolean equals(Object obj) {
        if (this == obj)
            return true;
        if (obj == null)
            return false;
        if (getClass() != obj.getClass())
            return false;
        Topic other = (Topic) obj;
        if (id != other.id)
            return false;
        if (name == null) {
            if (other.name != null)
                return false;
        } else if (!name.equals(other.name))
            return false;
        return true;
    }

}

现在我真的不知道问题出在哪里，因为我有一个吸气剂和Setter Methode！
