Looking for Hibernate - Spring examples

[theone]

Hi,

I'm new to both Hibernate and Spring Framework. I've been reading and have put together a web app using Spring Framework. Now I would like to add Hibernate functionality into the web app. I'm not sure how to go about doing it. I want to know how to add hibernate bean references to myweb-servlet.xml. Can some one show me some examples and what are some better ways of doing this?

I used Hibernate Synchronizer to create my mapping files and DAO's. I don't know exactly how to wire them into Spring Framework. Is there a better tool for generating the mapping files and DAO's and wire them together automatically?

Thank you

add hibernate bean references to myweb-servlet.xml
I suggest you put persistence related bean definitions in separate xml file like contextPersistence.xml. In web.xml, include all xml files pertinent to your environment in a <context-param> with name 'contextConfigLocation'. For example:

<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>/WEB-INF/contextPersistence.xml
,/WEB-INF/contextControllers.xml</param-value>
</context-param>

some examples and what are some better ways of doing this
In spring distribution, there is /sample/petclinic application that uses either hibernate or jdbc.

I highly recommend Matt Raible's Spring Live (http://jroller.com/page/raible) e-book, especially Chapter 2 (http://www.theserverside.com/articles/content/SpringLive_Chapter/chapter2.pdf). Helped me get started with both Spring and Hibernate in very short order.

Here's documentation and code of using Hibernate Synchronizer 3.1, Hibernate 3 and Spring:

Hibernate Synchronizer 3.1, Hibernate 3 and Spring Example (http://www.supergloo.com/blog/index.php/2005/11/10/using-hibernate-synchronizer-3-with-spring-and-hibernate-3)

Hope this helps. There are other posts about using different versions of Hibernate Sync and Hibernate as well.

In case you were not aware, Spring distribution comes with a set of samples which work on Hibernate and other persistence technologies. They are good practice for beginners as they contain common patterns which are independent of IDEs or plugin.

I have created a "Customer" table which has Name,id and phone
I have an embeddable class "Name" having firstname and lastname.

Code is as follows..

Customerbean.java
====================

@Entity
@Table(name="Customer")
public class CustomerRegistrationBean {

private CustomerName CustomerName;
private long phone;
private String customerid;

public CustomerRegistrationBean()
{
}

public CustomerRegistrationBean(String customerid,String firstname, String lastname, long phone)
{
this.customerid = customerid;
this.CustomerName = new CustomerName(firstname, lastname);
this.phone = phone;
}

@Embedded
@AttributeOverrides({
@AttributeOverride(name = "firstname", column = @Column(name = "firstname")),
@AttributeOverride(name = "lastname", column = @Column(name = "lastname"))
})
public CustomerName getCustomerName() {
return CustomerName;
}
public void setCustomerName(CustomerName CustomerName) {
this.CustomerName = CustomerName;
}

@Column(name="phone")
public long getPhone() {
return phone;
}
public void setPhone(long phone) {
this.phone = phone;
}

@Id
@Column(name="customerid" )
public String getCustomerid() {
return customerid;
}
public void setCustomerid(String customerid) {
this.customerid = customerid;
}
}


Name.java
++++++++++++++++==

@Embeddable
public class CustomerName implements Serializable
{

private static final long serialVersionUID = 4209558006137354948L;

private String firstname;
private String lastname;

public CustomerName()
{
}

public CustomerName(String firstname, String lastname)
{
this.firstname = firstname;
this.lastname = lastname;
}
@Column(name="firstname")
public String getFirstname() {
return firstname;
}

public void setFirstname(String firstname) {
this.firstname = firstname;
}
@Column(name="lastname")
public String getLastname() {
return lastname;
}

public void setLastname(String lastname) {
this.lastname = lastname;
}

================================================== ==========================

When I run this it is giving an exception

org.apache.jasper.JasperException: Invalid property 'firstname' of bean class [com.palnar.library.service.CustomerRegistrationBea n]: Bean property 'firstname' is not readable or has an invalid getter method: Does the return type of the getter match the parameter type of the setter?


Please help me in this.....
