Spring MVC simple example : Spring Tutorial
This is very basic running example for spring MVC. I developed this project in IMB RAD (
Rational Software Development Platform 6.0) and WebSphere Application Server v6.0.
Step1: Create one Dynamic web project (File -> New -> Dynamic Web Project) and give some name (Say SpringTrans).
Step2: Add spring.jar to project and copy spring.jar to WEB-INF\lib folder
Step3: Edit web.xml
<?xml version="1.0" encoding="UTF-8"?><web-app id="WebApp_ID" version="2.4" xmlns="http://java.sun.com/xml/ns/j2ee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd%22>
<display-name>SpringTrans</display-name>
<servlet>
<servlet-name>SpringTrans</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>SpringTrans</servlet-name>
<url-pattern>*.htm</url-pattern>
</servlet-mapping>
<welcome-file-list>
<welcome-file>login.jsp</welcome-file>
</welcome-file-list>
</web-app>
Step 4: Create one xml file SpringTrans-servlet.xml
Note: Name must be SpringTrans-servlet.xml, since we have given the servlet name SpringTrans, so it is SpringTrans-servlet.xml
<?xml version="1.0" encoding="UTF-8"?><!DOCTYPE beans PUBLIC "-//SPRING//DTD BEAN//EN" "http://www.springframework.org/dtd/spring-beans.dtd%22>
<beans>
<bean id="urlMapping" class="org.springframework.web.servlet.handler.SimpleUrlHandlerMapping">
<property name="urlMap">
<map>
<entry key="/loginCheck.htm" value-ref="userController"/>
</map>
</property>
</bean>
<bean id="userController" class="com.controller.UserController">
<property name="methodNameResolver">
<bean class="org.springframework.web.servlet.mvc.multiaction.PropertiesMethodNameResolver">
<property name="mappings">
<props>
<prop key="/loginCheck.htm">loginHandler</prop>
</props>
</property>
</bean>
</property>
</bean>
</beans>
Step 5: In Java Resource, create one package com.controller
Step 6: Create one Java file in this package UserController.java
package com.controller;
import java.io.IOException;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import org.springframework.web.servlet.ModelAndView;
import org.springframework.web.servlet.mvc.multiaction.MultiActionController;
public class UserController extends MultiActionController {
public ModelAndView loginHandler( HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
System.out.println("*********** FROM CONTROLLER *************");
String userInfoName = request.getParameter("userName");
String pass = request.getParameter("password");
System.out.println("User Name :: "+userInfoName);
System.out.println("Password :: "+pass);
return new ModelAndView("/SucessPage.jsp","user",userInfoName);
}
}
Step 7: Create jsp file inside WebContent folder
login.jsp
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<HTML>
<HEAD>
<TITLE>Login Page</TITLE>
</HEAD>
<BODY>
<P>LOGIN PAGE<BR></P>
<form action="loginCheck.htm">
<TABLE>
<TBODY>
<TR>
<TD width="326" align="right">User Name</TD>
<TD width="311"><input type="text" name="userName"/></TD>
</TR>
<TR>
<TD width="326" align="right">Password</TD>
<TD width="311"><input type="text" name="password"/></TD>
</TR>
<TR>
<TD width="326" align="right"><input type="submit" value="OK"/></TD>
<TD width="311"><input type="button" value="Cancel"/></TD>
</TR>
</TBODY>
</TABLE>
</form>
</BODY>
</HTML>
Step 8: SucessPage.jsp
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<HTML>
<HEAD>
<TITLE>SucessPage Page</TITLE>
</HEAD>
<BODY>
<P>Your Login is Sucessfull</P>
<%
String userName = request.getParameter("userName");
try{ out.print(userName); }catch(Exception e){}
%>
</BODY>
</HTML>
Step9:
Run http://localhost:9080/SpringTrans/
Rational Software Development Platform 6.0) and WebSphere Application Server v6.0.
Step1: Create one Dynamic web project (File -> New -> Dynamic Web Project) and give some name (Say SpringTrans).
Step2: Add spring.jar to project and copy spring.jar to WEB-INF\lib folder
Step3: Edit web.xml
<?xml version="1.0" encoding="UTF-8"?><web-app id="WebApp_ID" version="2.4" xmlns="http://java.sun.com/xml/ns/j2ee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd%22>
<display-name>SpringTrans</display-name>
<servlet>
<servlet-name>SpringTrans</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>SpringTrans</servlet-name>
<url-pattern>*.htm</url-pattern>
</servlet-mapping>
<welcome-file-list>
<welcome-file>login.jsp</welcome-file>
</welcome-file-list>
</web-app>
Step 4: Create one xml file SpringTrans-servlet.xml
Note: Name must be SpringTrans-servlet.xml, since we have given the servlet name SpringTrans, so it is SpringTrans-servlet.xml
<?xml version="1.0" encoding="UTF-8"?><!DOCTYPE beans PUBLIC "-//SPRING//DTD BEAN//EN" "http://www.springframework.org/dtd/spring-beans.dtd%22>
<beans>
<bean id="urlMapping" class="org.springframework.web.servlet.handler.SimpleUrlHandlerMapping">
<property name="urlMap">
<map>
<entry key="/loginCheck.htm" value-ref="userController"/>
</map>
</property>
</bean>
<bean id="userController" class="com.controller.UserController">
<property name="methodNameResolver">
<bean class="org.springframework.web.servlet.mvc.multiaction.PropertiesMethodNameResolver">
<property name="mappings">
<props>
<prop key="/loginCheck.htm">loginHandler</prop>
</props>
</property>
</bean>
</property>
</bean>
</beans>
Step 5: In Java Resource, create one package com.controller
Step 6: Create one Java file in this package UserController.java
package com.controller;
import java.io.IOException;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import org.springframework.web.servlet.ModelAndView;
import org.springframework.web.servlet.mvc.multiaction.MultiActionController;
public class UserController extends MultiActionController {
public ModelAndView loginHandler( HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
System.out.println("*********** FROM CONTROLLER *************");
String userInfoName = request.getParameter("userName");
String pass = request.getParameter("password");
System.out.println("User Name :: "+userInfoName);
System.out.println("Password :: "+pass);
return new ModelAndView("/SucessPage.jsp","user",userInfoName);
}
}
Step 7: Create jsp file inside WebContent folder
login.jsp
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<HTML>
<HEAD>
<TITLE>Login Page</TITLE>
</HEAD>
<BODY>
<P>LOGIN PAGE<BR></P>
<form action="loginCheck.htm">
<TABLE>
<TBODY>

<BODY>
<P>Your Login is Sucessfull</P>
<%
String userName = request.getParameter("userName");
try{ out.print(userName); }catch(Exception e){}
