• SpringMVC插件安装、环境配置及快速入门_学习笔记


    SpringMVC 是现在广泛应用的框架结构,我也只是一个初学者,一遍学习一遍梳理整合,如有错误,希望大神指点,别误人。

    MVC :Model-View-Control

    框架性质的C 层要完成的主要工作:封装web 请求为一个数据对象、调用业务逻辑层来处理数据对象、返回处理数据结果及相应的视图给用户。

    现在我们先说一下Spring的插件安装,我用的是Eclipse4.5.2版本

    如果你不知道自己用的什么版本的eclipse,在你eclipse的安装目录,打开:

    (直接拖到浏览器上就可以打开)

    然后打开eclipse,如图:

     

    在这个地址中填上:http://dist.springsource.com/release/TOOLS/update/e4.5.2/

    在4.5.2处改成你自己的版本就好。安装好,创建文件的时候就会有这个:

    (一会儿会用到)

    创建个动态项目工程,导入以下几个jar包:

    然后,我们需要在WEB-INF文件下创建一个上面的那个.xml文件,然后配置:

    <?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:cache="http://www.springframework.org/schema/cache"
        xmlns:context="http://www.springframework.org/schema/context"
        xmlns:mvc="http://www.springframework.org/schema/mvc"
        xsi:schemaLocation="http://www.springframework.org/schema/cache http://www.springframework.org/schema/cache/spring-cache-4.0.xsd
            http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-4.0.xsd
            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-4.0.xsd">
        
        <context:component-scan base-package="com.ysu.controller"></context:component-scan>
        <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        <property name="prefix" value="/WEB-INF/views/"></property>
        <property name="suffix" value=".jsp"></property>
        </bean>
    </beans>

    然后我们再配置以下web.xml文件,和配置servlet很像:

    <servlet>
            <servlet-name>springDispatcherServlet</servlet-name>
            <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
        <!--     <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>

    下面是我练习的一个例子,包含Ant风格及PathVariable变量、rest请求风格、POST请求转化为PUT请求。上传了一个.java 文件一个jsp文件:

    package com.ysu.controller;
    
    import org.springframework.stereotype.Controller;
    import org.springframework.web.bind.annotation.PathVariable;
    import org.springframework.web.bind.annotation.RequestMapping;
    import org.springframework.web.bind.annotation.RequestMethod;
    
    @Controller
    public class AController {
        private static final String SUCCESS="success";
        
        @RequestMapping(value="/testAnt/{id}")
        public String testAnt(@PathVariable(value="id") Integer id){
            System.out.println("++++++++++"+id);
            
            return SUCCESS;
        }
        
        @RequestMapping("/sayHello")
        public String sayHello(){
            return SUCCESS;
        }
        @RequestMapping(value="/order/{id}",method=RequestMethod.GET)
        public String getOrderById(@PathVariable(value="id") Integer id){
            System.out.println("----------"+id);
            return SUCCESS;
            
        }
        @RequestMapping(value="/order/{id}",method=RequestMethod.POST)
        public String getOrderById1(@PathVariable(value="id") Integer id){
            System.out.println("~~~~~~~~~~"+id);
            return SUCCESS;
            
        }
        @RequestMapping(value="/order/{id}",method=RequestMethod.PUT)
        public String getOrderById2(@PathVariable(value="id") Integer id){
            System.out.println("************"+id);
            return SUCCESS;
        
            
        }
    }
    <%@ page language="java" contentType="text/html; charset=UTF-8"
        pageEncoding="UTF-8"%>
