SpringMVC(二) SpringMVC Hello World

准备条件:

    STS(集成了Spring相关工具的Eclipse)

  Spring软件包 spring-framework-4.3.3.RELEASE-dist.zip。

步骤:

  1. 加入jar包。

Eclipse中新建一个动态的web工程。选择Tomcat 7.0,在WebContent-->WEB-INF-->lib目录下添加以下jar包。

spring-aop-4.3.3.RELEASE.jar

spring-beans-4.3.3.RELEASE.jar

spring-context-4.3.3.RELEASE.jar

spring-core-4.3.3.RELEASE.jar

pring-expression-4.3.3.RELEASE.jar

spring-web-4.3.3.RELEASE.jar

spring-webmvc-4.3.3.RELEASE.jar

另外还需要commons-logging-1.2.jar文件。

  2.  在web.xml中添加dispatcherServlet相关内容(使用快捷键Alt+/,在自动弹出的下拉条中,选择#dispatcherservlet)。web.xml配置文件内容可以参考如下内容:

复制代码
<?xml version="1.0" encoding="UTF-8"?>

<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd" version="3.0">

  <display-name>HelloWorld</display-name>

  <welcome-file-list>

    <welcome-file>index.html</welcome-file>

    <welcome-file>index.htm</welcome-file>

    <welcome-file>index.jsp</welcome-file>

    <welcome-file>default.html</welcome-file>

    <welcome-file>default.htm</welcome-file>

    <welcome-file>default.jsp</welcome-file>

  </welcome-file-list>

  <!-- The front controller of this Spring Web application, responsible for handling all application requests -->

<servlet>

<servlet-name>springDispatcherServlet</servlet-name>

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

<!-- 配置dispathcerservlet的一个初始化参数,设置配置文件的名称和位置 -->

<init-param>

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

<param-value>classpath:springmvc.xml</param-value>

</init-param>

<load-on-startup>1</load-on-startup>

</servlet>

<!-- Map all requests to the DispatcherServlet for handling -->

<servlet-mapping>

<servlet-name>springDispatcherServlet</servlet-name>

<url-pattern>/</url-pattern>

</servlet-mapping>

</web-app>
复制代码

  3. 加入SpringMVC的配置文件。在src目录下,参照以下关键步骤创建springmvc.xml文件。

参考如下代码:

复制代码
<?xml version="1.0" encoding="UTF-8"?>

<beans xmlns="http://www.springframework.org/schema/beans"

xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

xmlns:context="http://www.springframework.org/schema/context"

xmlns:mvc="http://www.springframework.org/schema/mvc"

xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd

http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.3.xsd

http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-4.3.xsd">

<!-- 配置自动扫描包 -->

<context:component-scan base-package="com.tiekui.springmvc.*"></context:component-scan>

<!-- 配置视图解析器:如何把handler方法返回给视图 -->

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

<property name="prefix" value="/WEB-INF/views/"></property>

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

</bean>

</beans>
复制代码

  4.编写请求的处理器。参考如下代码:

复制代码
package com.tiekui.springmvc.handlers;

import org.springframework.stereotype.Controller;

import org.springframework.web.bind.annotation.RequestMapping;

@Controller

public class HelloWorld {

  @RequestMapping("/helloworld")

  public String hello(){

  System.out.println("hello world");

  return "success";

  }

}
复制代码

 

  5. 编写视图。在WebContent目录下创建index.jsp文件,参考如下代码:

复制代码
<%@ page language="java" contentType="text/html; charset=ISO-8859-1"

pageEncoding="ISO-8859-1"%>

<!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=ISO-8859-1">

    <title>Insert title here</title>

  </head>

  <body>

    <a href="helloworld">Hello World</a>

  </body>

</html>
复制代码

 在/WEB-INF/views目录下创建success.jsp。内容参考如下代码:

复制代码
<%@ page language="java" contentType="text/html; charset=ISO-8859-1"

pageEncoding="ISO-8859-1"%>

<!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=ISO-8859-1">

  <title>Insert title here</title>

  </head>

  <body>

    <h1>Hello SpringMVC View</h1>

  </body>
  
</html>
