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

</form:form>
