最近要做一個Web項目，採用了Spring的MVC框架，特此記錄下這次搭建過程
1.準備Spring所需的MVC,IOC,數據庫等Jar包：
spring配置文件：
2.Web.xml文件
配置攔截請求DispatcherServlet，上下文監聽器SpringContext，過濾器Filter
<!-- 配置DispatcherServlet，指定攔截.do的請求, 請求轉發給對應的Controller處理 --> <servlet> <servlet-name>DtServlet</servlet-name> <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> <init-param> <param-name>contextConfigLocation</param-name> <param-value>/WEB-INF/classes/*-mvc.xml</param-value> </init-param> <load-on-startup>1</load-on-startup> </servlet> <servlet-mapping> <servlet-name>DtServlet</servlet-name> <url-pattern>*.do</url-pattern> </servlet-mapping> <welcome-file-list> <welcome-file>customDim.html</welcome-file> <welcome-file>index.jsp</welcome-file> </welcome-file-list> <!-- 配置Spring的上下文監聽器，並且指定Spring的xml配置文件的路徑 --> <listener> <listener-class> org.springframework.web.context.ContextLoaderListener </listener-class> </listener> <context-param> <param-name>contextConfigLocation</param-name> <param-value>classpath:spring-context.xml</param-value> </context-param> <!-- 配置filter，返回UTF-8編碼的數據格式 --> <filter> <filter-name>characterEncodingFilter</filter-name> <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class> <init-param> <param-name>encoding</param-name> <param-value>UTF-8</param-value> </init-param> <init-param> <param-name>forceEncoding</param-name> <param-value>true</param-value> </init-param> </filter> <filter-mapping> <filter-name>characterEncodingFilter</filter-name> <url-pattern>/*</url-pattern> </filter-mapping>
3. spring-context.xml上下文監聽器文件配置：IOC對象初始化
<context:property-placeholder location="classpath:jdbc.properties" />
<bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource"
destroy-method="close">
<property name="driverClassName" value="${jdbc.driver}" />
<property name="url" value="${jdbc.url}" />
<property name="username" value="${jdbc.username}" />
<property name="password" value="${jdbc.password}" />
<property name="maxActive" value="${jdbc.maxActive}" />
<property name="maxIdle" value="${jdbc.maxIdle}" />
<property name="maxWait" value="${jdbc.maxWait}" />
<property name="defaultAutoCommit" value="${jdbc.defaultAutoCommit}" />
</bean>
<bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
<property name="dataSource" ref="dataSource" />
</bean>
<bean id="dataDao" class="com.sun.dt.dao.impl.DataDaoImpl">
<property name="dataSource" ref="dataSource"></property>
</bean>
<bean id="dataService" class="com.sun.dt.service.impl.DataServiceImpl">
<property name="dataDao" ref="dataDao"></property>
</bean>4. jdbc.properties文件
jdbc.driver=oracle.jdbc.driver.OracleDriver jdbc.url=jdbc:oracle:thin:@127.0.0.1:1526:testdb jdbc.username=test001 jdbc.password=123456 jdbc.maxActive=10 jdbc.maxIdle=3 jdbc.maxWait=5 jdbc.defaultAutoCommit=false
5.spring-mvc.xml中MVC攔截後轉發配置controller
<beans:beans> <!-- 加載Spring的全局配置文件 --> <beans:import resource="spring-context.xml" /> <!-- SpringMVC配置 --> <!-- 通過component-scan 讓Spring掃描com.sun.dt.controller下的所有的類，讓Spring的代碼註解生效 --> <context:component-scan base-package="com.pingan.dt.controller"></context:component-scan> <!-- 配置SpringMVC的視圖渲染器， 讓其前綴爲:/ 後綴爲.jsp 將視圖渲染到/page/<method返回值>.jsp中 --> <beans:bean class="org.springframework.web.servlet.view.InternalResourceViewResolver" p:prefix="/page/" p:suffix=".jsp"> </beans:bean> </beans:beans>
6.MVC中Conntroller類
通過spring-mvc.xml文件中配置攔截的請求都轉給com.sun.dt.conntroller類處理，類中可針對不同不同URL請求給不同的conntroller類和其方法處理

import java.io.PrintWriter;

import java.util.HashMap;
