SpringMVC搭建+实例

想做一点自己喜欢的东西,研究了一下springMVC,所以就自己搭建一个小demo,可供大家吐槽。

  1. 先建一个WEB工程,这个相信大家都会,这里不在多说。
  2. 去网上下载spring jar包,然后在WEB-INF下新建一个lib文件,将下载的jar包放进去。如下图


  3. 在WEB/INF下建一个web.xml文件,内容如下:
    <?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"
        id="WebApp_ID" version="3.0">
        <display-name>springMVCtest</display-name>
        <welcome-file-list>
            <welcome-file>index.jsp</welcome-file>
        </welcome-file-list>
        
        <listener>
            <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
        </listener>
        <servlet>
            <servlet-name>springMVCtest</servlet-name>
            <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
            <load-on-startup>1</load-on-startup>
        </servlet>
        <servlet-mapping>
            <servlet-name>springMVCtest</servlet-name>
            <url-pattern>/</url-pattern>
        </servlet-mapping>
            <!-- 加载spring的xml配置文件到 spring的上下文容器中 -->
        <context-param>
            <param-name>contextConfigLocation</param-name>
            <param-value>classpath:applicationContext.xml</param-value>
        </context-param>
    </web-app>

    注意:servlet-name的名字必须和接下来要创建的servlet.xml的名字要对应。 context-param指定applicationContext.xml 文件的位置。

  4. 在WEB-INF下新建一个xml,因为我上文中定义的名字是springMVCtest,所以,文件名字为springMVCtest-servlet.xml:
    <?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:p="http://www.springframework.org/schema/p"
        xmlns:context="http://www.springframework.org/schema/context"
        xmlns:task="http://www.springframework.org/schema/task"
        xmlns:util="http://www.springframework.org/schema/util" xmlns:mvc="http://www.springframework.org/schema/mvc"
        xsi:schemaLocation="
          http://www.springframework.org/schema/beans
          http://www.springframework.org/schema/beans/spring-beans-4.2.xsd
          http://www.springframework.org/schema/util
          http://www.springframework.org/schema/util/spring-util-4.2.xsd
          http://www.springframework.org/schema/context 
          http://www.springframework.org/schema/context/spring-context-4.2.xsd
          http://www.springframework.org/schema/mvc
          http://www.springframework.org/schema/mvc/spring-mvc-4.2.xsd
          http://www.springframework.org/schema/task 
          http://www.springframework.org/schema/task/spring-task.xsd ">
    
        <!-- 使用默认的注解映射 
        <mvc:annotation-driven />
        <mvc:resources location="/" mapping="/index.html" />
          <context:annotation-config></context:annotation-config>-->
    
        <!-- 自动扫描controller包中的控制器 -->
        <context:component-scan base-package="com.controller" />
        <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
            <property name="prefix" value="/WEB-INF/jsp/" />
            <property name="suffix" value=".jsp" />
        </bean>
        
        <!-- <bean id="urlMapping" class="org.springframework.web.servlet.handler.SimpleUrlHandlerMapping">
            <property name="mappings">
                <props>
                    <prop key="/index.do">controllerDoem</prop>
                </props>
            </property>
        </bean>
        
         <bean id="controllerDoem" class="com.controller">
            <property name="view">
                <value>index</value>
            </property>
        </bean>-->
    
    </beans>
  5. 在src目录下新建文件applicationContext.xml
    <?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:p="http://www.springframework.org/schema/p"
        xmlns:context="http://www.springframework.org/schema/context"
        xmlns:aop="http://www.springframework.org/schema/aop" xmlns:tx="http://www.springframework.org/schema/tx"
        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.xsd
           http://www.springframework.org/schema/tx
           http://www.springframework.org/schema/tx/spring-tx.xsd
           http://www.springframework.org/schema/aop
           http://www.springframework.org/schema/aop/spring-aop.xsd">
    </beans>
  6. 在src下新建一个包名,com.controller,新建一个类DemoController,注:这里的类名必须已Controller结尾,之前我写其他的类名,然后项目一直404,后来改成这样之后就好了,具体原因,还没搞清楚,知道的大神欢迎回复。
    package com.controller;
    
    import org.springframework.stereotype.Controller;
    import org.springframework.web.bind.annotation.RequestMapping;
    import org.springframework.web.servlet.ModelAndView;
    
    @Controller
    public class DemoController {
        @RequestMapping("/index")
        public ModelAndView index(){
            //创建模型跟视图,用于渲染页面。并且指定要返回的页面为index页面
            ModelAndView mav = new ModelAndView("index");
            return mav;
        }
        
    }
  7. 最后一步,在WEB-INF下新建目录jsp,里面新建文件index.jsp
    <%@ 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>hahahaha</h1>
    </body>
    </html>
  8. 将项目部署到tomcat下,启动tomcat,就可以运行了,访问http://localhost:8080/springMVCtest/index

    最后配上整个项目结构:

    搞定!(如有错误,请大神指出。)
