Hibernate ORM失败：org.hibernate.MappingException：无法确定类型：

Question

I am having a problem in hibernate config xml.

Entity:

package com.ds.supercar.model.places;

public class Location {

private int locationid;
private String street;
private String city;
private String state;
private String pin;

public Location() {
    // TODO Auto-generated constructor stub
}

public Location(int locationid, String street, String city, String state, String pin) {
    super();
    this.locationid = locationid;
    this.street = street;
    this.city = city;
    this.state = state;
    this.pin = pin;
}

public int getLocationid() {
    return locationid;
}

public void setLocationid(int locationid) {
    this.locationid = locationid;
}

public String getStreet() {
    return street;
}

public void setStreet(String street) {
    this.street = street;
}

public String getCity() {
    return city;
}

public void setCity(String city) {
    this.city = city;
}

public String getState() {
    return state;
}

public void setState(String state) {
    this.state = state;
}

public String getPin() {
    return pin;
}

public void setPin(String pin) {
    this.pin = pin;
}

}

hbm xml file:

<hibernate-mapping>
<class name="com.ds.supercar.model.places.Location" table="supercarlocation" schema="supercar">
    <id name="locationid" column="locationid">
        <generator class="increment"/>
    </id>
    <property name="street"/>
    <property name="city"/>
    <property name="state"/>
    <property name="pin"/>
    </class>

Exception:

Please help me with this exception:

Answer 1

it seems you forgot to put mapping resource in your hibernate config file( between sessionFactory tags ) so use this and map your hbm's.

<mapping resource="com.ds.supercar.model.places.Location.hbm.xml" />

hope this helps you!
