Spring MVC Getting Started configuration

1. Copy the required jar to the project directory Web-inf/lib

2. Configure Web. XML To configure the front controller Org.springframework.web.servlet.DispatcherServlet

<servlet>

<servlet-name>springmvc</servlet-name>

<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>

<init-param>

<param-name>contextConfigLocation</param-name>

<param-value>classpath:spring_config/applicationContext-mvc.xml</param-value>

</init-param>

</servlet>

<servlet-mapping>

<servlet-name>springmvc</servlet-name>

<url-pattern>*.do</url-pattern>

</servlet-mapping>

3. Create a Spring MVC control core configuration: Applicationcontext-mvc.xml

Configuring the Controller

<bean id= "Login" name= "/login.do" class= "Com.beifeng.controller.LoginController" ></bean>

Configuration Attempt Parser

<bean class= "Org.springframework.web.servlet.view.InternalResourceViewResolver" >

<!--prefixes--

<property name= "prefix" value= "/jsp/" ></property>

<!--suffix--

<property name= "suffix" value= ". JSP" ></property>

</bean>

4. Write the controller class Logincontroller must inherit Abstractcontroller rewrite handlerequestinternal

@Override

protected Modelandview handlerequestinternal (HttpServletRequest request,

HttpServletResponse arg1) throws Exception {

TODO auto-generated Method stub

String userName = Request.getparameter ("UserName");

String USERPW = Request.getparameter ("USERPW");

System. out. println ("------I am SPRINGMVC controller---------");

System. out. println ("account number:" +username);

System. out. println ("account number:" +USERPW);

Modelandview Mav = new modelandview ("index");

Analog Call Model

if ("admin". Equals (UserName) && "123". Equals (USERPW)) {

Mav.addobject ("message", "User login successful!");

}Else{

Mav.addobject ("message", "Incorrect account or password!") ");

}

return Mav;

}

Returns data and attempts to modelandview Mav = new Modelandview ("index");

5. Writing JSP page display data

Use {$message} in the JSP interface to display the message variable
