Debug level Hibernate log excerpt:


Hi guys,

My CompositeIdCategoryVisitedStatistic is as follows:

package com.stufftolet.model.posting;
import java.io.Serializable;
import java.util.Date;

public class CompositeIdCategoryVisitedStatistic implements Serializable {
private Category category;
private Date visited;
public CompositeIdCategoryVisitedStatistic() {
}

public CompositeIdCategoryVisitedStatistic(Category category, Date visited) {
super();
this.category = category;
this.visited = visited;
}

/**
* @return Returns the categoryId.
* @hibernate.many-to-one cascade="save-update" column="fk_category_id"
*/
public Category getCategory() {
return category;
}
/**
* @return Returns the visited.
* @hibernate.property column="visited" not-null="true"
*/
public Date getVisited() {
return visited;
}
/**
* @param category the category to set
*/
public void setCategory(Category category) {
this.category = category;
}
/**
* @param visited the visited to set
*/
public void setVisited(Date visited) {
this.visited = visited;
}
public boolean equals(Object o) {
if (o instanceof CompositeIdCategoryVisitedStatistic) {
CompositeIdCategoryVisitedStatistic that = (CompositeIdCategoryVisitedStatistic) o;
return this.category.equals(that.category)
&& this.visited.equals(that.visited);
} else {
return false;
}
}

public int hashCode() {
return category.hashCode() + visited.hashCode();
}
}


I just want the field version to increment 1 point everytime I update the row with all the field's value remain the same. The problem is after updating, the field is not incremented. pls help.....
