建立maven工程css

建立完成後，目錄結構以下：html

優化目錄結構：java

加載spring配置mysql

1）在pom中加入須要的依賴，包含了spring，velocity，mybatisweb

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

                </configuration>
            </plugin>
        </plugins>
    </build>
</project>

2）編寫引導文件 web.xmlspring

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns="http://java.sun.com/xml/ns/j2ee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://JAVA.sun.com/xml/ns/j2ee http://java.sun.com/xml/ns/j2ee/web-app_2_5.xsd"
    version="2.5">

    <display-name>springExecise</display-name>

    <welcome-file-list>
        <welcome-file>index.vm</welcome-file>
    </welcome-file-list>

    <servlet>
        <servlet-name>springmvc</servlet-name>
        <servlet-class>org.springframework.web.servlet.DispatcherServlet
        </servlet-class>
        <init-param>
            <param-name>contextConfigLocation</param-name>
            <param-value>classpath*:spring/springmvc-servlet.xml</param-value>
        </init-param>
        <load-on-startup>1</load-on-startup>
    </servlet>

    <servlet-mapping>
        <servlet-name>springmvc</servlet-name>
        <url-pattern>/</url-pattern>
    </servlet-mapping>
</web-app>

3) 編寫spring配置文件：springmvc-servlet.xmlsql

建立以下文件，並填寫內容數據庫

<?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:mvc="http://www.springframework.org/schema/mvc" 
    xmlns:util="http://www.springframework.org/schema/util"
    xmlns:context="http://www.springframework.org/schema/context"
    xsi:schemaLocation="
    http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.1.xsd
    http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.1.xsd
    http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-3.1.xsd
    http://www.springframework.org/schema/util http://www.springframework.org/schema/util/spring-util-3.1.xsd
    ">
    <!-- 向spring中注入BeanPostProcessor，使spring能識別被@Autowired、@ Resource 、@ PostConstruct、@ PreDestroy、PersistenceContext、@Required註解 -->
    <context:annotation-config />
    <!-- 配置註解的掃描路徑，該配置項其實也包含了自動注入上述processor的功能，因此上面的不寫也ok -->
    <context:component-scan base-package="test.tt.springE"></context:component-scan>

    <!-- 資源文件讀取 
    <bean id="configproperties" class="org.springframework.beans.factory.config.PropertiesFactoryBean">
        <property name="location" value="classpath:config/db.properties" />
    </bean>-->
    
    <!-- 註冊一些bean，這些bean能夠基於註解來註冊bean、完成requestmapping等 -->
    <!-- 和<context:annotation-config />的區別是什麼？？ 標籤namspace不一樣-->
    <mvc:annotation-driven/>  
    <!-- 將靜態資源的處理經由Spring MVC框架交回Web應用服務器處理 -->
    <mvc:default-servlet-handler /> 
    
    <!-- 容許靜態資源放在任何地方，如WEB-INF目錄下、類路徑下等 -->
    <!-- 將/css/的目錄，映射爲/css/*，映射到/css/**的請求，不會到controller處理，而是直接訪問靜態資源 -->
    <mvc:resources location="/css/" mapping="/css/**"/>
    
    <!-- 引入mybatis-數據庫配置文件 
    <import resource="classpath*:spring/mybatis-config.xml" />  -->
    
    <!-- 引入velocity模板 -->
    <bean id="velocityConfig" class="org.springframework.web.servlet.view.velocity.VelocityConfigurer">
        <property name="resourceLoaderPath" value="/WEB-INF/velocity/" /><!--指定模板存放的路徑 -->
        <property name="velocityProperties">
            <props>
                <prop key="input.encoding">UTF-8</prop>
                <prop key="output.encoding">UTF-8</prop>
                <prop key="contentType">text/html;charset=UTF-8</prop>
            </props>
        </property>
    </bean>
    <!--配置視圖的顯示 -->
    <bean id="ViewResolver" class="org.springframework.web.servlet.view.velocity.VelocityViewResolver">
        <property name="prefix" value="" /><!-- 視圖文件的前綴，即存放的路徑 -->
        <property name="suffix" value=".vm" /><!-- 視圖文件的後綴名 -->
        <property name="contentType" value="text/html;charset=UTF-8" />
    
        <property name="exposeSpringMacroHelpers" value="true" /><!--是否使用spring對宏定義的支持 -->
        <property name="exposeRequestAttributes" value="true" /><!--是否開放request屬性 -->
        <property name="requestContextAttribute" value="rc" /><!--request屬性引用名稱 -->
    </bean>
    
</beans>

寫controllerapache

package test.tt.springE.controller;

import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestParam;

@Controller
public class IndexController {

    @RequestMapping(value="/")
    public String hello(@RequestParam(value="name",required=false,defaultValue="you")String name,Model model){
        model.addAttribute("name", name);
        return "index";
    }
}
