Hibernate Reverse Engineering not generating proper domain code STS

Question

I have started a project in Spring and was successfully able to run a sample application on Spring communicating with one table in MySQL database.

Now, for learning purpose, I created two more tables in that same database and want to generate domain classes by Reverse Engineering from Hibernate Tools. I followed https://www.mkyong.com/hibernate/how-to-generate-code-with-hibernate-tools/ this tutorial. My classes are getting generated but it doesn't contain any annotations or mappings which an entity/domain class should contain. Below is the code generated for reference:

// default package
// Generated Mar 29, 2018 8:18:21 AM by Hibernate Tools 5.2.8.Final

import java.util.Date;
import java.util.HashSet;
import java.util.Set;

/**
 * Product generated by hbm2java
 */
public class Product implements java.io.Serializable {

    private Integer productId;
    private String productName;
    private String createdBy;
    private Date createdDate;
    private String modifiedBy;
    private Date modifiedDate;
    private Set measurmentCategories = new HashSet(0);

    public Product() {
    }

    public Product(String productName) {
        this.productName = productName;
    }

    public Product(String productName, String createdBy, Date createdDate, String modifiedBy, Date modifiedDate,
            Set measurmentCategories) {
        this.productName = productName;
        this.createdBy = createdBy;
        this.createdDate = createdDate;
        this.modifiedBy = modifiedBy;
        this.modifiedDate = modifiedDate;
        this.measurmentCategories = measurmentCategories;
    }

    public Integer getProductId() {
        return this.productId;
    }

    public void setProductId(Integer productId) {
        this.productId = productId;
    }

    public String getProductName() {
        return this.productName;
    }

    public void setProductName(String productName) {
        this.productName = productName;
    }

    public String getCreatedBy() {
        return this.createdBy;
    }

    public void setCreatedBy(String createdBy) {
        this.createdBy = createdBy;
    }

    public Date getCreatedDate() {
        return this.createdDate;
    }

    public void setCreatedDate(Date createdDate) {
        this.createdDate = createdDate;
    }

    public String getModifiedBy() {
        return this.modifiedBy;
    }

    public void setModifiedBy(String modifiedBy) {
        this.modifiedBy = modifiedBy;
    }

    public Date getModifiedDate() {
        return this.modifiedDate;
    }

    public void setModifiedDate(Date modifiedDate) {
        this.modifiedDate = modifiedDate;
    }

    public Set getMeasurmentCategories() {
        return this.measurmentCategories;
    }

    public void setMeasurmentCategories(Set measurmentCategories) {
        this.measurmentCategories = measurmentCategories;
    }

}

Though, the class should contain an annotation @Entity, and all variables should contain a proper annotations. But it's not there in the generated code.

You need to make sure that you selected the Hibernate version as 5.2.

In “Exporter” tab make sure Generate EJB3 annotations is checked.

Sukhpal, by default it is implementing java.io.Serializable interface. Should Spring models/domains implement this interface? Because the Spring tutorial I followed, they didn't implement this interface while creating a domain class manually. – Murtaza Mar 29 '18 at 10:42
Not required by the specification though. For more information read similar answer here : https://stackoverflow.com/questions/2020904/when-and-why-jpa-entities-should-implement-serializable-interface – Sukhpal Singh Mar 29 '18 at 14:58
I have checked both checkboxes but still, annotations are not generated. I checked each as well (one by one) with no positive results. Each time it generates java classes without annotations. – Hemant Nagpal Apr 15 '20 at 15:10

In addition to the Generate EJB3 annotations, make sure to select Annotations (jdk 1.5+) in the hibernate configuration "Main" tab.
