Simple Spring-Hibernate DAO problem.
I have two tables in the DB, Categories and Products
Category one-to-many Products
Below is the mapping def. and a sneak view of the Product bean:
<hibernate-mapping>
<class name="com.fivestaroffice.databeans.Category" table="categories">
<id name="id" type="int" column="id">
<generator class="native"/>
</id>
<property name="name" column="name"/>
<property name="notes" column="notes"/>
<property name="image" column="image"/>
</class>
</hibernate-mapping>
<hibernate-mapping>
<class name="com.fivestaroffice.databeans.Product" table="products">
<id name="code" type="string" column="code">
<generator class="assigned"/>
</id>
<many-to-one name="parentCate" column="parentCate" class="com.fivestaroffice.databeans.Category"/>
<property name="innerSize" column="innerSize"/>
<property name="pkgsPerCtn" column="pkgsPerCtn"/>
<property name="unitPrice" column="unitPrice"/>
<property name="pkgPrice" column="pkgPrice"/>
<many-to-one name="minimalOrderUnit" column="minimalOrderUnit" class="com.fivestaroffice.databeans.OrderUnit"/>
<property name="minimalOrderAmt" column="minimalOrderAmt"/>
</class>
</hibernate-mapping>
public class Product {
...
private Category parentCate;
public void setParentCate(Category parentCate) {
this.parentCate = parentCate;
}
public Category getParentCate() {
return parentCate;
}
...
}
I'm trying to retrieve all product records from the DB in a controller. All product objects are created, but their parentCate (type Category) are all null.
When I save products into the DB, I simply set the products' parentCate through the Product bean's setter, and Category id's are all correctly saved.
Why I can't get them out?
