spring:设置映射访问路径或 xml配置访问路径 (spring mvc form表单)

项目hello,

在src/main/java下面建一个目录: charpter2

一.xml配置访问路径

web.xml

<web-app>

  <display-name>Archetype Created Web Application</display-name>
  


  <servlet>  
    <servlet-name>chapter2</servlet-name>  
    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>  
    <load-on-startup>1</load-on-startup>  
</servlet>  
<servlet-mapping>  
    <servlet-name>chapter2</servlet-name>  
    <url-pattern>/</url-pattern>  
</servlet-mapping>   

</web-app>

chapter2-servlet.xml

<beans xmlns="http://www.springframework.org/schema/beans"
       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"
       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.xsd 
					       http://www.springframework.org/schema/context 
					       http://www.springframework.org/schema/context/spring-context.xsd">

<!-- HandlerMapping -->
<bean class="org.springframework.web.servlet.handler.BeanNameUrlHandlerMapping"/>
<!-- HandlerAdapter --> 
<bean class="org.springframework.web.servlet.mvc.SimpleControllerHandlerAdapter"/>
    

<!-- ViewResolver -->  
<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
	<property name="viewClass" value="org.springframework.web.servlet.view.JstlView"/>
	<property name="prefix" value="/WEB-INF/jsp/"/>
	<property name="suffix" value=".jsp"/>
</bean>

<!-- 处理器 -->  
<bean name="/helloworld" class="chapter2.web.controller.HelloWorldController"/>  
<!--
<bean name="/student" class="chapter2.web.controller.StudentController"/>  
-->
       
</beans>

chapter2/HelloWorldController.java

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

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

public class HelloWorldController implements Controller {

	public ModelAndView handleRequest(HttpServletRequest req, HttpServletResponse res) throws Exception {
		// TODO Auto-generated method stub
			ModelAndView mv = new ModelAndView();  
	       //添加模型数据 可以是任意的POJO对象  
	       mv.addObject("message", "Hello World!");  
	       //设置逻辑视图名，视图解析器会根据该名字解析到具体的视图页面  
	       mv.setViewName("hello");  
	       return mv;  
	}

}

注意在 chapter2-servlet.xml中添加处理器配置:

<!-- 处理器 -->  
<bean name="/helloworld" class="chapter2.web.controller.HelloWorldController"/>  

然后再WEB-INF/目录下新建jsp目录
web-inf/jsp/hello.jsp

<%@ page language="java" contentType="text/html; charset=utf-8"    pageEncoding="utf-8"%>
<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core"%>
<%@ page isELIgnored="false" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8">
<title>hello</title>
</head>
<body>

dddd
<br>
${message}


</body>
</html>

　　访问地址是: 项目地址/hello/helloworld

二。映射访问配置

首先配置文件有3: applicationContext.xml, web.xml, chapter2-servlet.xml

web.xml

<!DOCTYPE web-app PUBLIC
 "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN"
 "http://java.sun.com/dtd/web-app_2_3.dtd" >
  
<web-app>

  <display-name>Archetype Created Web Application</display-name>
  
<!--配置文件路径-->
<context-param>
 	<param-name>contextConfigLocation</param-name>
	<param-value>/WEB-INF/applicationContext.xml</param-value>
</context-param>
<listener>
	<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>

  <servlet>  
    <servlet-name>chapter2</servlet-name>  
    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>  
    <load-on-startup>1</load-on-startup>  
</servlet>  
<servlet-mapping>  
    <servlet-name>chapter2</servlet-name>  
    <url-pattern>/</url-pattern>  
</servlet-mapping>   

</web-app>

　　chapter2-servlet.xml

<beans xmlns="http://www.springframework.org/schema/beans"
       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"
       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.xsd 
					       http://www.springframework.org/schema/context 
					       http://www.springframework.org/schema/context/spring-context.xsd">
      
 

<!-- 默认的注解映射的支持 -->
<mvc:annotation-driven /> 
 <!-- 自动扫描的包名 -->
<context:component-scan base-package="chapter2.*" />

      
       
</beans>

　　applicationContext.xml

<beans xmlns="http://www.springframework.org/schema/beans"
       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"
       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.xsd 
					       http://www.springframework.org/schema/context 
					       http://www.springframework.org/schema/context/spring-context.xsd">

<!-- HandlerMapping -->
<bean class="org.springframework.web.servlet.handler.BeanNameUrlHandlerMapping"/>
<!-- HandlerAdapter --> 
<bean class="org.springframework.web.servlet.mvc.SimpleControllerHandlerAdapter"/>
    

<!-- ViewResolver -->  
<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
	<property name="viewClass" value="org.springframework.web.servlet.view.JstlView"/>
	<property name="prefix" value="/WEB-INF/jsp/"/>
	<property name="suffix" value=".jsp"/>
</bean>


       
</beans>

r然后就是java代码:

chapter2/Student.java

public class Student {

	
	private Integer id;
	private Integer age;
	private String name;
	
	public Integer getId() {
		return id;
	}
	public void setId(Integer id) {
		this.id = id;
	}
	
	public Integer getAge() {
		return age;
	}
	public void setAge(Integer age) {
		this.age = age;
	}
	
	public String getName() {
		return name;
	}
	public void setName(String name) {
		this.name = name;
	}
	
	
}

　　chapter2/StudentController.java

import org.springframework.stereotype.Controller;
import org.springframework.web.servlet.ModelAndView;
import org.springframework.web.bind.annotation.ModelAttribute;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.ui.ModelMap;


@Controller
public class StudentController {

	
	@RequestMapping(value="/student", method=RequestMethod.GET)
	public ModelAndView student()
	{
		return new ModelAndView("student", "command", new Student());
		
	}
	
	@RequestMapping(value="/assStudent", method=RequestMethod.POST)
	public String addStudent(@ModelAttribute("SpringWeb")Student student, ModelMap model)
	{
		model.addAttribute("name", student.getName());
		model.addAttribute("age", student.getAge());
		model.addAttribute("id", student.getId());
		
		return "student_result";
		
	}
	
	
	
}

jsp文件

student.js

</table>
</form:form>

</body>
</html>

　　student_result.jsp
