Inserting data in hibernate Java

Question

I am reading data from a text file in hibernate, but problem is that last 2 columns(i.e age and salary column) are not inserted into the person table. Intially I set the <property name = hibernate.hbm2ddl.auto>create</property> to create while using ClientPerson1 class as shown below and on retrieving this table using ClientPerson2 as below changed it to update.

//Pojo class.

package com.aamir;

public class Person {

private int id;
private String name;
private String address;
private String education;
private int age;
private int salary;

public int getId() {
    return id;
}
public void setId(int id) {
    this.id = id;
}
public String getName() {
    return name;
}
public void setName(String name) {
    this.name = name;
}
public String getAddress() {
    return address;
}
public void setAddress(String address) {
    this.address = address;
}
public String getEducation() {
    return education;
}
public void setEducation(String education) {
    this.education = education;
}
public int getAge() {
    return age;
}
public void setAge(int age) {
    this.age = age;
}
public int getSalary() {
    return salary;
}
public void setSalary(int salary) {
    this.salary = salary;
}

public String toString() {

    StringBuffer sb = new StringBuffer();
    sb.append("id = " + id);
    sb.append(", name = " + name);
    sb.append(", address = " + address);
    sb.append(", education = " + education);
    sb.append(", age = " + age);
    sb.append(", salary = " + salary);

    return sb.toString();
}

}

Answer 1

I guess you have a typo in person.hbm.xml:

   <properties name="age"/>

   <properties name="salary"/>

instead of

   <property name="age"/>

   <property name="salary"/>
