Implementing Spring DAO concept in Struts MVC

[yogi reddy]

Hi,

I am new to Struts and Spring, I have developed a small registration application in Struts and it is working fine :D . I have also started learning Spring 2.5 and completed till Spring JDBC concept. I have succeeded in creating a standalone Spring JDBC main program which performs insert update and delete operations.

Now I want to remove all the boilerplate JBDC code from my Struts based registration application and integrate it with Spring JDBC.

Can someone please suggest me the right direction on how to implement this in Spring like how do I load the wiring information (beans.xml) into the application, how do i get the instance of the DAO Impl in the service object, what are the additional configurations I have to add in web.xml and struts-config.xml?

My beans.xml
***********
<beans>
<bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource">
<property name="driverClassName" value="oracle.jdbc.OracleDriver"/>
<property name="url" value="jdbc:oracle:thin:@localhost:1521:orcl"/>
<property name="username" value="ora1"/>
<property name="password" value="oracle"/>
</bean>
<bean id="jdbcTemplate" class="org.springframework.jdbc.core.JdbcTemplate">
<property name="dataSource" ref="dataSource"/>
</bean>
<bean id="manageUserDAO" class="com.regis.dao.ManageUserDAOImpl">
<property name="jdbcTemplate" ref="jdbcTemplate"/>
</bean>
</beans>

(Although I don't know why you'd want to learn Struts 1 at this point unless you have a compelling reason to do so.)

Dave - Thanks a lot for your response. I really do not have any supporting reason to explain you why I started with Struts 1.3.8 but I am sure that I also want to learn Struts 2. Can you suggest any nice book for that (Though this is not the relevant forum to post this)?

I will try to add the Spring DAO to my existing struts application and see if it works.

Thanks,
Yogesh

Dave - I tried to implement the sping dao with struts and it worked. Thanks a ton.

Cheers,

Struts 2 in Action by Donald Brown, Chad Michael Davis, and Scott Stanlick is a good reference.

[yogi reddy]

Dennis - Thanks for your information. I will start with this material.

Cheers,
Yogesh

Yogesh, what application were you build using Spring...can you share the guide (web site or etc) on how to develop that? Also if you find any sample step by step practical guidance for a building Struts 2 application please post it too.

Thank You.

There's a step-by-step walkthrough of a simple Struts 2 application on the Struts 2 documentation wiki.

Struts 1.3.8, Struts 2 and Spring and completely different. It only makes sense to mix and match if you have reusable or legacy code.

[David Newton]

Mixing Spring with either makes perfect sense, though.

Spring is so versatile, it can work with any major MVC framework. That is being said, how good is Spring MVC compared to Struts MVC. Any pros of using Spring with Spring MVC vs Spring with Struts MVC?

Thanks.

You avoid learning Struts.

Up until Spring 3.0 I've preferred Struts 2--but that's just a personal preference. (I haven't looked at the 3.0 stuff yet, so don't have any opinion.) If you're doing greenfield development it's solely a matter of technical and/or aesthetic preference, in my opinion--I think they're both really nice.
