基于XML配置的SpringMVC

1、添加jar

2、web.xml配置

 xmlns="http://java.sun.com/xml/ns/javaee"
 xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
 xsi:schemaLocation="http://java.sun.com/xml/ns/javaee
 http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd">
   
 
 
  action
  org.springframework.web.servlet.DispatcherServlet
  
  
   contextConfigLocation
   classpath:action-servlet.xml
  
 
 
  action
  *.do
 
 
 
    index.jsp
 

3、配置action-servlet.xml

 xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
 xmlns:mvc="http://www.springframework.org/schema/mvc"
 xmlns:cOntext="http://www.springframework.org/schema/context"
 xmlns:aop="http://www.springframework.org/schema/aop"
 xmlns:tx="http://www.springframework.org/schema/tx"
 xsi:schemaLocation="http://www.springframework.org/schema/beans
      http://www.springframework.org/schema/beans/spring-beans.xsd
      http://www.springframework.org/schema/mvc
      http://www.springframework.org/schema/mvc/spring-mvc-3.0.xsd
      http://www.springframework.org/schema/context
      http://www.springframework.org/schema/context/spring-context-3.0.xsd
      http://www.springframework.org/schema/aop
      http://www.springframework.org/schema/aop/spring-aop-3.0.xsd
      http://www.springframework.org/schema/tx
      http://www.springframework.org/schema/tx/spring-tx-3.0.xsd ">
 
 
 
  
 
 
 
 
  
   
    homeController     //通过这个配置，对应id是homeController的可以通过这四个地址访问。
    homeController
    homeController
    homeController
   
  
  
 
 
 
 
  
 
 
 
 
 
 
 
 
 
 
        
name必须是successView,这里对应的是success.jsp
              formView必须是userForm,这里对应的是userForm.jsp
 
 
 
 
  
   
   
    wizard/1     对应的是wizard中的1.jsp
    wizard/2                                         2.jsp
    wizard/3                                         3.jsp
   
  
 
 
 
 
  
  ="/WEB-INF/jsps/">
  
  value=".jsp">property>
 

4、编写实体bean:

package cn.itcast.springmvc.domain;

public class User {
 private String name;
 private String address;
 private Integer age;
 private String tel;
 
 /**
  * @return the name
  */
 public String getName() {
  return name;
 }
 
 /**
  * @param name the name to set
  */
 public void setName(String name) {
  this.name = name;
 }
 
 /**
  * @return the address
  */
 public String getAddress() {
  return address;
 }
 /**
  * @param address the address to set
  */
 public void setAddress(String address) {
  this.address = address;
 }
 
 /**
  * @return the age
  */
 public Integer getAge() {
  return age;
 }
 
 /**
  * @param age the age to set
  */
 public void setAge(Integer age) {
  this.age = age;
 }
 
 /**
  * @return the tel
  */
 public String getTel() {
  return tel;
 }
 
 /**
  * @param tel the tel to set
  */
 public void setTel(String tel) {
  this.tel = tel;
 }
}

5、编写HomeController，代码如下：

package cn.itcast.springmvc.controller;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

import org.springframework.web.servlet.ModelAndView;
import org.springframework.web.servlet.mvc.AbstractController;

public class HomeController extends AbstractController {

 @Override
 protected ModelAndView handleRequestInternal(HttpServletRequest req,
   HttpServletResponse resp) throws Exception {
  String name = req.getParameter("name");
  String msg = "hello " &＃43; name &＃43; " !";
  System.out.println("HomeController...");
  return new ModelAndView("helloworld","msg",msg);
 }

}

6、HomeController返回到的页面未：helloworld.jsp

<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>

 
   
  
 
 
 
    This is helloworld.jsp

    ${requestScope.msg}
 

7、编写MyCommandController，代码如下：

package cn.itcast.springmvc.controller;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

import org.springframework.validation.BindException;
import org.springframework.web.servlet.ModelAndView;
import org.springframework.web.servlet.mvc.AbstractCommandController;

import cn.itcast.springmvc.domain.User;

/**
 *命令控制器
 */
public class MyCommandController extends AbstractCommandController {
 
 public MyCommandController(){
  //注册命令类
  this.setCommandClass(User.class);
  //命令名称
  this.setCommandName("user");
 }

 @Override
 protected ModelAndView handle(HttpServletRequest request,
   HttpServletResponse response, Object command, BindException errors)
   throws Exception {
  User u = (User)command;
  System.out.println("name:" &＃43; u.getName() &＃43; " address:" &＃43; u.getAddress());
  return new ModelAndView("commandView","user",u);
 }

}

8、commandView.jsp

<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>

 
   
  
 
 
 
    This is commandView.jsp

    name:${user.name }

    address:${user.address }

    age:${user.age }

    tel:${user.tel }
 

9、MyFormController

package cn.itcast.springmvc.controller;

import org.springframework.web.servlet.mvc.SimpleFormController;

import cn.itcast.springmvc.domain.User;

public class MyFormController extends SimpleFormController {

 public MyFormController() {
  this.setCommandClass(User.class);
  this.setCommandName("user");
 }

 @Override
 protected void doSubmitAction(Object command) throws Exception {
  User u = (User)command;
  System.out.println(u.getName());
  System.out.println("doSubmitAction");
  super.doSubmitAction(command);
 }

}

对应的userForm.jsp

<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>
<%
String path = request.getContextPath();
String basePath = request.getScheme()&＃43;"://"&＃43;request.getServerName()&＃43;":"&＃43;request.getServerPort()&＃43;path&＃43;"/";
%>

 
   
  
 
 
 
    /form.do" method="post">
     name:

     age:

     address:

     tel:

     
   
 

对应的success.jsp

<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>

 
   
 
 
 
     This is success.jsp!
 

10、MyWizardFormController的代码如下：

package cn.itcast.springmvc.controller;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

import org.springframework.validation.BindException;
import org.springframework.web.servlet.ModelAndView;
import org.springframework.web.servlet.mvc.AbstractWizardFormController;

import cn.itcast.springmvc.domain.User;

public class MyWizardFormController extends AbstractWizardFormController {
 
 public MyWizardFormController(){
  this.setCommandClass(User.class);
  this.setCommandName("user");
 }

 @Override
 protected ModelAndView processCancel(HttpServletRequest request,
   HttpServletResponse response, Object command, BindException errors)
   throws Exception {
  return new ModelAndView("helloworld");         
//跳转到helloworld.jsp
 }
 
 @Override
 protected ModelAndView processFinish(HttpServletRequest request,
   HttpServletResponse response, Object command, BindException errors)
   throws Exception {
  User u = (User) command;
  System.out.println(u);
  return new ModelAndView("helloworld");     //跳转到helloworld.jsp
 }

}

相应的WEB-INF/wizard/1.jsp
<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>
<%
String path = request.getContextPath();
String basePath = request.getScheme()&＃43;"://"&＃43;request.getServerName()&＃43;":"&＃43;request.getServerPort()&＃43;path&＃43;"/";
%>

 
   
  
 
 
 
    /wizard.do" method="post">
     name:value="${requestScope.user.name}"><br>            //标出的颜色区域可以用于回显
             //必须有下划线，且&＃20540;是确定的
         //必须有下划线，且&＃20540;是确定的
   
 

相应的WEB-INF/wizard/2.jsp

<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>
<%
String path = request.getContextPath();
String basePath = request.getScheme()&＃43;"://"&＃43;request.getServerName()&＃43;":"&＃43;request.getServerPort()&＃43;path&＃43;"/";
%>

 
   
  
 
 
 
    /wizard.do" method="post">
     address:="${requestScope.user.address }"><br>
         //表示跳转到最开始的页面。
     
         
   
 

相应的WEB-INF/wizard/3.jsp

<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>
<%
String path = request.getContextPath();
String basePath = request.getScheme()&＃43;"://"&＃43;request.getServerName()&＃43;":"&＃43;request.getServerPort()&＃43;path&＃43;"/";
%>

 
   
  
 
 
 
    /wizard.do" method="post">
     age:

     tel:
