生成持久性映射->通过休眠映射不可用Intellij

Question

I am brand new to Hibernate and I am trying have created the following class, which I now want to generate the hibernate mappings for.

package com.simpleprogrammer;

public class User {

    private int id;
    private String name;
    private int total;
    private int goal;

    public int getId() {
        return id;
    }
    public void setId(int id) {
        this.id = id;
    }
    public int getGoal() {
        return goal;
    }
    public void setGoal(int goal) {
        this.goal = goal;
    }
    public int getTotal() {
        return total;
    }
    public void setTotal(int total) {
        this.total = total;
    }
    public String getName() {
        return name;
    }
    public void setName(String name) {
        this.name = name;
    }
}

When I right-click on Persistence I expect to see "Generate Persistence Mappings" -> "By Hibernate Mappings" to be available. But it is not. All I can see is "By database schema". Does anybody know why "By Hibernate Mappings is not available?

Will supply more information if requested or required, I am following a pluralsight course which is approx 2 years out of date and using Eclipse, just to make things even more complex!

Answer 1

You need to add:

@Entity at start of class:

@Entity
public class User {

    @Id
    private int id;
    ...

Then add <mapping class="com.simpleprogrammer.User"/> to hibernate.cfg.xml before closing of element </session-factory>

also med sure that you add ID annotation ( @Id ) to variable id.
