Spring Crud

Spring CRUD Example using One to One Mapping of Two Tables

Posted by Dinesh Rajput

In this example show how to write a simple web based application with CRUD operation using Spring3 MVC Framwork with Hibernate3 using Annotation handling two database tables(Category & Publication), which can handle CRUD inside its controllers. To start with it, let us have working STS IDE in place and follow the following steps to develop a Dynamic Form based Web Application using Spring Web Framework:

Step 1: Create a Database DAVDB on MySql Database and also we create Category and Publication tables on this database.

Category Table

view plainprint?

1. CREATE TABLE `category` (  
2.   `categoryId` int(11) NOT NULL AUTO_INCREMENT,  
3.   `categoryName` varchar(255) DEFAULT NULL,  
4.   PRIMARY KEY (`categoryId`)  
5. )   

Publication Table

view plainprint?

1. CREATE TABLE `publication` (  
2.   `pubId` int(11) NOT NULL AUTO_INCREMENT,  
3.   `content` varchar(255) DEFAULT NULL,  
4.   `Title` varchar(255) DEFAULT NULL,  
5.   `categoryId` int(11) DEFAULT NULL,  
6.   PRIMARY KEY (`pubId`),  
7.   KEY `FK23254A0CAF274936` (`categoryId`),  
8.   CONSTRAINT `FK23254A0CAF274936` FOREIGN KEY (`categoryId`) REFERENCES `category` (`categoryId`)  
9. )  

Step 2: Create a database.properties for database configuration information in the resources folder under src folder in the created project.

1. database.driver=com.mysql.jdbc.Driver    
2.     database.url=jdbc:mysql://localhost:3306/DAVDB    
3.     database.user=root    
4.     database.password=root    
5.     hibernate.dialect=org.hibernate.dialect.MySQLDialect    
6.     hibernate.show_sql=true    
7.     hibernate.hbm2ddl.auto=create  

Step 3: Create a Dynamic Web Project with a name elhumeante and create packages com.dineshonjava.controller, com.dineshonjava.bean, com.dineshonjava.dao, com.dineshonjava.service, com.dineshonjava.model under the src folder in the created project.

Step 4: Add below mentioned Spring 3.0 and Hibernate 3.0 related libraries and other libraries into the folder WebRoot/WEB-INF/lib.


Step 5: Create a Java class CategoryController, PublicationController, CategoryBean, PublicationBean, CategoryDao, CategoryDaoImpl, PublicationDao, PublicationDaoImpl, CategoryService, CategoryServiceImpl, PublicationService, PublicationServiceImpl under the respective packages..

Step 6: Create Spring configuration files web.xml and sdnext-servlet.xml under the WebRoot/WEB-INF/ and WebRoot/WEB-INF/config folders.

Step 7: Create a sub-folder with a name views under the WebRoot/WEB-INF folder. Create a view file addCategory.jsp and addPublication.jsp under this sub-folder.

Step 8: The final step is to create the content of all the source and configuration files name sdnext-servlet.xml under the sub-folder /WebRoot/WEB-INF/config and export the application as explained below.

Application Architecture

We will have a layered architecture for our demo application. The database will be accessed by a Data Access layer popularly called as DAO Layer(CategoryDao, PublicationDao). This layer will use Hibernate API to interact with database. The DAO layer will be invoked by a service layer. In our application we will have a Service interface called CategoryService, PublicationService.
