Java Spring Hibernate and Reflection

I have 5 tables in MySQL (words_1, words_2... words_5) with the same fields (id,words,sinonim). In the field "words" I put different count of words (for words_1 = 1 word, for words_5 = 5 words). I create 5 classes and Repo for those. Constructors and methods are the same.

import javax.persistence.*;

@Entity
@Table(name = "words_2")
public class Words2 {
    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    private Long id;
    private String word;
    private String sinonim;

    public Words2() {
    }

    public Words2(String word, String sinonim) {
        this.word = word;
        this.sinonim = sinonim;
    }

    public Long getId() {
        return id;
    }

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

    public String getWord() {
        return word;
    }

    public void setWord(String word) {
        this.word = word;
    }

    public String getSinonim() {
        return sinonim;
    }

    public void setSinonim(String sinonim) {
        this.sinonim = sinonim;
    }
}

How I can take my classes fields and methods, using variable(int = 1..5) with Reflection, for Class and same Repo identification?
