SpringMVC入門項目，用戶登錄系統，詳細記錄了SpringMVC的開發流程！ ...
一.用戶登錄系統環境配置：
1.1:開發環境：
Windows7(x86_64);Eclipse Java EE IDE for Web Developers.Version: Oxygen.1a Release (4.7.1a); java version "1.8.0_73"
1.2:開發框架：
spring-framework-5.0.3.RELEASE DButils
1.3：所需jar包截圖：
二.資料庫的設計：
三.開發流程：
1.1.配置web.xml文件
1 <!-- 註冊SpringMVC的前端控制器DispatchcerServlet --> 2 <servlet> 3 <servlet-name>DispatchcerServletSpringMVC</servlet-name> 4 <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> 5 <!-- 初始化SpringMVC容器 --> 6 <init-param> 7 <param-name>contextConfigLocation</param-name> 8 <param-value>classpath:SpringMVC.xml</param-value> 9 </init-param> 10 </servlet> 11 <!-- 攔截 以.action結尾的請求--> 12 <servlet-mapping> 13 <servlet-name>DispatchcerServletSpringMVC</servlet-name> 14 <url-pattern>*.action</url-pattern> 15 </servlet-mapping>
1.2.配置SpringMVC.xml文件
1 <?xml version="1.0" encoding="UTF-8"?> 2 <beans xmlns="http://www.springframework.org/schema/beans" 3 xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 4 xmlns:context="http://www.springframework.org/schema/context" 5 xmlns:mvc="http://www.springframework.org/schema/mvc" 6 xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd 7 http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.1.xsd 8 http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-4.1.xsd"> 9 <!-- 指定使用註解方式配置 --> 10 <!-- 掃描以下包及其子包內容 --> 11 <mvc:annotation-driven></mvc:annotation-driven> 12 <context:component-scan base-package="com.login.handler"></context:component-scan> 13 <!-- 不處理靜態內容 --> 14 <mvc:default-servlet-handler/> 15 <!--配置視圖解析器--> 16 <bean id="internalResourceViewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver"> 17 <!-- 首碼 --> 18 <property name="prefix" value="/WEB-INF/admin/" /> 19 <!-- 尾碼 --> 20 <property name="suffix" value=".jsp" /> 21 </bean> 22 </beans>
1.3.C3P0資料庫連接池的配置：
1 <?xml version="1.0" encoding="UTF-8"?> 2 <c3p0-config> 3 <named-config name="hello"> 4 <property name="driverClass">com.mysql.jdbc.Driver</property> 5 <property name="jdbcUrl">jdbc:mysql://localhost:3306/springmvc</property> 6 <property name="user">root</property> 7 <property name="password">root</property> 8 <property name="initialPoolSize">2</property> 9 <property name="maxPoolSize">5</property> 10 </named-config> 11 </c3p0-config>
1.4.視圖層目錄結構：
1.5.各層關鍵代碼展示：
