Spring框架web项目实战全代码分享
以下是一个最简单的示例
1、新建一个标准的javaweb项目
2、导入spring所需的一些基本的jar包
3、配置web.xml文件
xmlns="http://java.sun.com/xml/ns/javaee" xmlns:xsi="http://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"> classpath*:applicationContext*.xml, org.springframework.web.context.ContextLoaderListener
xmlns="http://java.sun.com/xml/ns/javaee"
xmlns:xsi="http://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">
classpath*:applicationContext*.xml,
org.springframework.web.context.ContextLoaderListener
4、添加spring配置文件applicationContext
5、对applicationContext.xml文件做最简单的配置
xmlns:xsi="http://w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://springframework.org/schema/beans http://springframework.org/schema/beans/spring-beans-3.0.xsd" default-lazy-init="false" default-autowire="byName">
xmlns:xsi="http://w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://springframework.org/schema/beans http://springframework.org/schema/beans/spring-beans-3.0.xsd"
default-lazy-init="false" default-autowire="byName">
beans——xml文件的根节点。
xmlns——是XMLNameSpace的缩写,因为XML文件的标签名称都是自定义的,自己写的和其他人定义的标签很有可能会重复命名,而功能却不一样,所以需要加上一个namespace来区分这个xml文件和其他的xml文件,类似于java中的package。
xmlns:xsi——是指xml文件遵守xml规范,xsi全名:xmlschemainstance,是指具体用到的schema资源文件里定义的元素所准守的规范。即/spring-beans-2.0.xsd这个文件里定义的元素遵守什么标准。
xsi:schemaLocation——是指,本文档里的xml元素所遵守的规范,schemaLocation属性用来引用(schema)模式文档,解析器可以在需要的情况下使用这个文档对XML实例文档进行校验。它的值(URI)是成对出现的,第一个值表示命名空间,第二个值则表示描述该命名空间的模式文档的具体位置,两个值之间以空格分隔。
6、新建一个实体类User.java
package com.po;
public class User {
private String name;
private String age;
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getAge() {
return age;
}
public void setAge(String age) {
this.age = age;
}
}
7、测试
public static void main(String[] args) {
// TODO Auto-generated method stub
ApplicationContext ac = new FileSystemXmlApplicationContext("config/applicationContext.xml");
User user =(User)ac.getBean("user");
System.out.println(user.getName());
}
输出
这就实现web项目搭建基础spring框架。接下来就做一些真正项目中会用到的一些扩展
可以在web.xml中配置一些spring框架集成的功能或其他设置
org.springframework.orm.hibernate3.support.OpenSessionInViewFilter
其中jspf就是做一些全局的声明
<%@ page language="java" contentType="text/html; charset=UTF-8"
pageEncoding="UTF-8"%>
<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core"%>
<%@ taglib prefix="fn" uri="http://java.sun.com/jsp/jstl/functions"%>
<%@ taglib prefix="fmt" uri="http://java.sun.com/jsp/jstl/fmt"%>
<%@ taglib prefix="fnc" uri="/WEB-INF/tlds/fnc.tld" %>
<%@ taglib tagdir="/WEB-INF/tags" prefix="mytag"%>
