Step 1: Create a Dynamic Web Project with a name SpringEmployeeApp and create a package com.dineshonjava.controller under the src folder in the created project.
Step 2: Add below mentioned Spring 3.0 libraries and other libraries into the folder WebRoot/WEB-INF/lib.
- commons-logging-1.1.1.jar
- org.springframework.asm-3.0.0.jar
- org.springframework.beans-3.0.0.jar
- org.springframework.context-3.0.0.jar
- org.springframework.core-3.0.0.jar
- org.springframework.expression-3.0.0.jar
- org.springframework.web.servlet-3.0.0.jar
- org.springframework.web-3.0.0.jar
- spring-web.3.0.0.jar
Step 3: Create a Java class EmployeeController and Employee under the com.dineshonjava.controller com.dineshonjava.bean package respectively.
Step 4: Create Spring configuration files Web.xml and sdnext-servlet.xml under the WebRoot/WEB-INF/ folder.
Step 5: Create a sub-folder with a name views under the WebRoot/WEB-INF folder. Create a view file employeeForm.jsp and employeeDetail.jsp under this sub-folder.
Step 6: 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.
Software versions used to run the sample code:
- Spring 3.0
- Java 1.6
- Tomcat 7
- JSTL 1.2
- STS Java EE IDE
Web Application Structure:
Employee.java
package com.dineshonjava.emp.bean;
/**
* @author Dinesh Rajput
*
*/
public class Employee {
private int empId;
private String name;
private Long salary;
private int age;
/**
* @return the empId
*/
public int getEmpId() {
return empId;
}
/**
* @param empId the empId to set
*/
public void setEmpId(int empId) {
this.empId = empId;
}
/**
* @return the name
*/
public String getName() {
return name;
}
/**
* @param name the name to set
*/
public void setName(String name) {
this.name = name;
}
/**
* @return the salary
*/
public Long getSalary() {
return salary;
}
/**
* @param salary the salary to set
*/
public void setSalary(Long salary) {
this.salary = salary;
}
/**
* @return the age
*/
public int getAge() {
return age;
}
/**
* @param age the age to set
*/
public void setAge(int age) {
this.age = age;
}
public String toString(){
return "Employee{ name-"+name+" age-"+age+" salary-"+salary+"}";
}
}
EmployeeController.java
package com.dineshonjava.emp.controller;
import org.springframework.stereotype.Controller;
import org.springframework.ui.ModelMap;
import org.springframework.web.bind.annotation.ModelAttribute;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.servlet.ModelAndView;
import com.dineshonjava.emp.bean.Employee;
/**
* @author Dinesh Rajput
*
*/
@Controller
public class EmployeeController {
@RequestMapping(value = "/employee", method = RequestMethod.GET)
public ModelAndView employee() {
return new ModelAndView("employeeForm", "command", new Employee());
}
@RequestMapping(value = "/addEmployee", method = RequestMethod.POST)
public String addEmployee(@ModelAttribute("SpringWeb")Employee employee, ModelMap model) {
model.addAttribute("name", employee.getName());
model.addAttribute("age", employee.getAge());
model.addAttribute("empId", employee.getEmpId());
model.addAttribute("salary", employee.getSalary());
return "employeeDetail";
}
}
Here the first service method employee(), we have passed a blank Employee object in the ModelAndView object with name “command” because the spring framework expects an object with name “command” if you are using tags in your JSP file. So when employee() method is called it returns employeeForm.jsp view.
Second service method addEmployee() will be called against a POST method on the sdnext/addEmployee URL. You will prepare your model object based on the submitted information. Finally a “employeeDetail” view will be returned from the service method, which will result in rendering employeeDetail.jsp

Once you are done with creating source and configuration files, export your application. Right click on your application and use Export-> WAR File option and save your SpringEmplyeeApp.war file in Tomcat’s webapps folder.
Now start your Tomcat server and make sure you are able to access other web pages from webapps folder using a standard browser. Now try a URL http://localhost:8080/sdnext/employee and you should see the following result if everything is fine with your Spring Web Application:
After submitting required information click on submit button to submit the form. You should see the following result if everything is fine with your Spring Web Application:
