Struts + Spring + Hibernate integration example

Published: April 27, 2010 , Updated: April 22, 2010 , Author: mkyong

Download this Struts 1.x + Spring + Hibernate example – Struts-Spring-Hibernate-Example.zip

In this tutorials, you will learn how to create a simple customer management (add and select) web application, Maven as project management tool, Struts 1.x as web framework, Spring as dependency injection framework and Hibernate as database ORM framework.

The overall integration architecture is look like following :

Struts (Web page) <---> Spring DI <--> Hibernate (DAO) <---> Database

To integrate all those technologies together, you should..

Integrate Spring with Hibernate with Spring’s “LocalSessionFactoryBean” class.
Integrate Spring with Struts via Spring’s ready make Struts plug-in – “ContextLoaderPlugIn“.

1. Project Structure

This is this final project structure.

2. Table script

Create a customer table to store the customer details.

DROP TABLE IF EXISTS `mkyong`.`customer`;
CREATE TABLE  `mkyong`.`customer` (
  `CUSTOMER_ID` BIGINT(20) UNSIGNED NOT NULL AUTO_INCREMENT,
  `NAME` VARCHAR(45) NOT NULL,
  `ADDRESS` VARCHAR(255) NOT NULL,
  `CREATED_DATE` datetime NOT NULL,
  PRIMARY KEY (`CUSTOMER_ID`)
) ENGINE=InnoDB AUTO_INCREMENT=10 DEFAULT CHARSET=utf8;

3. Maven details

Define all the Struts, Spring and Hibernate dependency libraries in pom.xml.
pom.xml

4. Hibernate

Nothing much need to configure in Hibernate, just declare a customer XML mapping file and model.
Customer.hbm.xml

<?xml version="1.0"?>
<!DOCTYPE hibernate-mapping PUBLIC 
"-//Hibernate/Hibernate Mapping DTD 3.0//EN"
"http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd">
<hibernate-mapping>
    <class name="com.mkyong.customer.model.Customer" 
        table="customer" catalog="mkyong">
 
        <id name="customerId" type="long">
            <column name="CUSTOMER_ID" />
            <generator class="identity" />
        </id>
        <property name="name" type="string">
            <column name="NAME" length="45" not-null="true" />
        </property>
        <property name="address" type="string">
            <column name="ADDRESS" not-null="true" />
        </property>
        <property name="createdDate" type="timestamp">
            <column name="CREATED_DATE" length="19" not-null="true" />
        </property>
    </class>
</hibernate-mapping>

Customer.java

package com.mkyong.customer.model;
 
import java.util.Date;
 
public class Customer implements java.io.Serializable {
 
	private long customerId;
	private String name;
	private String address;
	private Date createdDate;
 
	//getter and setter methods
 
}

5. Spring

Spring’s beans declaration for Business Object (BO) and Data Access Object (DAO). The DAO class (CustomerDaoImpl.java) is extends Spring’s “HibernateDaoSupport” class to access the Hibernate function easily.
CustomerBean.xml

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
	xsi:schemaLocation="http://www.springframework.org/schema/beans 
	http://www.springframework.org/schema/beans/spring-beans-2.5.xsd">
 
   	<bean id="customerBo" 
                class="com.mkyong.customer.bo.impl.CustomerBoImpl" >
   		<property name="customerDao" ref="customerDao" />
   	</bean>
 
   	<bean id="customerDao" 
                class="com.mkyong.customer.dao.impl.CustomerDaoImpl" >
   		<property name="sessionFactory" ref="sessionFactory"></property>
   	</bean>
 
</beans>

CustomerBo.java

package com.mkyong.customer.bo;
 
import java.util.List;
 
import com.mkyong.customer.model.Customer;
 
public interface CustomerBo{
 
	void addCustomer(Customer customer);
 
	List<Customer> findAllCustomer();
 
}

CustomerBoImpl.java

package com.mkyong.customer.bo.impl;
 
import java.util.List;
 
import com.mkyong.customer.bo.CustomerBo;
import com.mkyong.customer.dao.CustomerDao;
import com.mkyong.customer.model.Customer;
 
public class CustomerBoImpl implements CustomerBo{
 
	CustomerDao customerDao;
 
	public void setCustomerDao(CustomerDao customerDao) {
		this.customerDao = customerDao;
	}
 
	public void addCustomer(Customer customer){
 
		customerDao.addCustomer(customer);
 
	}
 
	public List<Customer> findAllCustomer(){
 
		return customerDao.findAllCustomer();
	}
}

CustomerDao.java

package com.mkyong.customer.dao;
 
import java.util.List;
 
import com.mkyong.customer.model.Customer;
 
public interface CustomerDao{
 
	void addCustomer(Customer customer);
 
	List<Customer> findAllCustomer();
 
}

CustomerDaoImpl.java

package com.mkyong.customer.dao.impl;
 
import java.util.Date;
import java.util.List;
 
import com.mkyong.customer.dao.CustomerDao;
import com.mkyong.customer.model.Customer;
import org.springframework.orm.hibernate3.support.HibernateDaoSupport;
 
public class CustomerDaoImpl extends 
       HibernateDaoSupport implements CustomerDao{
 
	public void addCustomer(Customer customer){
 
		customer.setCreatedDate(new Date());
		getHibernateTemplate().save(customer);
 
	}
 
	public List<Customer> findAllCustomer(){
 
		return getHibernateTemplate().find("from Customer");
 
	}
}

6. Spring + Hibernate

Declare the database details and integrate Spring and Hibernate together via “LocalSessionFactoryBean“.
database.properties

jdbc.driverClassName=com.mysql.jdbc.Driver
jdbc.url=jdbc:mysql://localhost:3306/mkyong
jdbc.username=root
jdbc.password=password

DataSource.xml

<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans-2.5.xsd">
 
 <bean 
   class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
   <property name="location">
     <value>WEB-INF/classes/config/database/properties/database.properties</value>
   </property>
</bean>
 
  <bean id="dataSource" 
         class="org.springframework.jdbc.datasource.DriverManagerDataSource">
	<property name="driverClassName" value="${jdbc.driverClassName}" />
	<property name="url" value="${jdbc.url}" />
	<property name="username" value="${jdbc.username}" />
	<property name="password" value="${jdbc.password}" />
  </bean>
 
</beans>

HibernateSessionFactory.xml

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans-2.5.xsd">
 
<!-- Hibernate session factory -->
<bean id="sessionFactory" 
     class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">
 
    <property name="dataSource">
      <ref bean="dataSource"/>
    </property>
 
    <property name="hibernateProperties">
       <props>
         <prop key="hibernate.dialect">org.hibernate.dialect.MySQLDialect</prop>
         <prop key="hibernate.show_sql">true</prop>
       </props>
    </property>
 
    <property name="mappingResources">
	<list>
          <value>com/mkyong/customer/hibernate/Customer.hbm.xml</value>
	</list>
     </property>	
 
</bean>
</beans>

SpringBeans.xml

<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans-2.5.xsd">
 
	<!-- Database Configuration -->
	<import resource="config/database/spring/DataSource.xml"/>
	<import resource="config/database/spring/HibernateSessionFactory.xml"/>
 
	<!-- Beans Declaration -->
	<import resource="com/mkyong/customer/spring/CustomerBean.xml"/>
 
</beans>

7. Struts + Spring

To integrate Spring with Struts, you need to registering a Spring’s build-in Struts plug-in “ContextLoaderPlugIn” in struts-config.xml file. In Action class, it have to extends the Spring’s “ActionSupport” class, and you can get the Spring bean via getWebApplicationContext().

AddCustomerAction.java

package com.mkyong.customer.action;
 
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
 
import org.apache.commons.beanutils.BeanUtils;
import org.apache.struts.action.ActionForm;
import org.apache.struts.action.ActionForward;
import org.apache.struts.action.ActionMapping;
import org.springframework.web.struts.ActionSupport;
 
import com.mkyong.customer.bo.CustomerBo;
import com.mkyong.customer.form.CustomerForm;
import com.mkyong.customer.model.Customer;
 
public class AddCustomerAction extends ActionSupport{
 
public ActionForward execute(ActionMapping mapping,ActionForm form,
	HttpServletRequest request,HttpServletResponse response) 
        throws Exception {
 
	CustomerBo customerBo =
 	  (CustomerBo) getWebApplicationContext().getBean("customerBo");
 
	CustomerForm customerForm = (CustomerForm)form;
	Customer customer = new Customer();
 
	//copy customerform to model
	BeanUtils.copyProperties(customer, customerForm);
 
	//save it
	customerBo.addCustomer(customer);
 
	return mapping.findForward("success");
 
  }
}

ListCustomerAction.java

package com.mkyong.customer.action;
 
import java.util.List;
 
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
 
import org.apache.struts.action.ActionForm;
import org.apache.struts.action.ActionForward;
import org.apache.struts.action.ActionMapping;
import org.apache.struts.action.DynaActionForm;
import org.springframework.web.struts.ActionSupport;
 
import com.mkyong.customer.bo.CustomerBo;
import com.mkyong.customer.model.Customer;
 
public class ListCustomerAction extends ActionSupport{
 
  public ActionForward execute(ActionMapping mapping,ActionForm form,
	HttpServletRequest request,HttpServletResponse response) 
        throws Exception {
 
	CustomerBo customerBo =
	  (CustomerBo) getWebApplicationContext().getBean("customerBo");
 
	DynaActionForm dynaCustomerListForm = (DynaActionForm)form;
 
	List<Customer> list = customerBo.findAllCustomer();
 
	dynaCustomerListForm.set("customerList", list);
 
	return mapping.findForward("success");
 
  }
}

CustomerForm.java

package com.mkyong.customer.form;
 
import javax.servlet.http.HttpServletRequest;
 
import org.apache.struts.action.ActionErrors;
import org.apache.struts.action.ActionForm;
import org.apache.struts.action.ActionMapping;
import org.apache.struts.action.ActionMessage;
 
public class CustomerForm extends ActionForm {
 
	private String name;
	private String address;
 
	//getter and setter, basic validation
 
}

Customer.properties

#customer module label message
customer.label.name = Name
customer.label.address = Address
 
customer.label.button.submit = Submit
customer.label.button.reset = Reset
 
#customer module error message
customer.err.name.required = Name is required
customer.err.address.required = Address is required

Hi its very useful.. can you please give me the Jar files required to run this project.
becoz i am getting the following problems while configuring.
Unbound classpath variable: ‘M2_REPO/antlr/antlr/2.7.7/antlr-2.7.7.jar’ in project StrutsSpringExample
like the above error i am getting around 33 errors. i think this problem is becoz of jar files missing in the class path. can you please upload all the required jar files or give me the link to download.
thanks in advance.

Yes asm-1.5.3.jar does the problem. You can solve it like this: to pom.xml add:
asm
asm
3.1
and after you did: mvn install go to target directory, enter to war and there delete old asm-1.5.3.jar. New asm-3.1.jar must stay there!

  hmm it delete my code:

  <artifactId>asm</artifactId>
  <version>3.1</version>
  </dependency>

  404 means you access an URL which is doesn’t exists, you did configured something wrong, try download the attached example and compare with yours.

  Downloaded your project and do a quick test, hits
  Unable to instantiate default tuplizer [org.hibernate.tuple.entity.PojoEntityTuplizer] .... Caused by: java.lang.NoSuchMethodError: org.objectweb.asm.ClassWriter
  Your included library is using ‘asm-1.5.3.jar’, which is quite old and causing the issue, try upgrade to ‘asm-3.1.jar’.
  In my attached project, it will download the ‘asm-3.1.jar’ automatically, wonder why you will get the old asm library? Is you include it manually?

    “In my attached project, it will download the ‘asm-3.1.jar’ automatically, wonder why you will get the old asm library? Is you include it manually?”
    I use maven to get all dependency jar files. After that, I copy all file to WEB-INF/lib folder. Have I do it in right way?

      Obviously, the SpringBeans.xml is not found, resource folder problem. The attached example in this article should working fine, tested. Please compare with yours, or you can configure it easily
      http://www.mkyong.com/maven/how-to-change-maven-resources-folder-location/
      Let Maven handle the dependencies, no point to copy it manually. See below , in case you afraid the dependencies are not deploy correctly in Eclipse debugging environment.

        Hi Mykyong,
        I have downloaded your project example again. And it run.
        In the project which I sent to you, I think that I added wrong dependency jars by hand.
        In old project, i have done like below:
        1.Rownload your project.
        2.run mvn eclipse:eclipse command.
        3.Run the project on tomcat 5.5 server, and it didn’t work.And in WEB-INF folder i added new subfolder name by lib and then, I copy some dependency jar files to that folder(lib). And then, I configure Java Build Path point to lib folder. And I think I had mistake in this step.
        Instead of doing like step 3, I follwed your instruction link to change dependency libraries (http://www.mkyong.com/maven/maven-dependency-libraries-not-deploy-in-eclipse-ide/), after that I restart the workspace. And that’s great, It run.
        -After running it and thinking about the bugs with SpringBean.xml? I have an question that what’s actually address of “/WEB-INF/classes/SpringBeans.xml”. And i found it in D:\SpringProject\.metadata\.plugins\org.eclipse.wst.server.core\tmp0\wtpwebapps\StrutsSpringExample\WEB-INF\classes. It means that when we run the project in server it temporary deploy to a tmp folder in server.
        And i found that why my old project could not run when manually added lib folder as I did.
        –> the problem is that dependency lib directory different from SpringBeans.xml directory (Is it right,Mkyong?)
        Anyway, thanks you alot, hope to see new your tutorial about j2ee.

        Good to know it work to you.
        Q : “the problem is that dependency lib directory different from SpringBeans.xml directory (Is it right,Mkyong?)”
        A : Not really sure, since i do not have this problem, just make the XML file is exists in the Eclipse “org.eclipse.wst.server.core” plugin folder, it’s where the Eclipse run your project.
