Spring MVC-step-by-step (1)

废话少讲。下面是Web.XML的内容

<?xml version="1.0" encoding="UTF-8"?>
<web-app version="2.4"
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_4.xsd">
<!-- 设置DispatcherServlet类的位置和加载参数-->
<servlet>
<servlet-name>springapp</servlet-name>
<servlet-class>org.springFramework.web.servlet.DispatcherServlet</servlet-class>
<load-on-startup>1</load-on-startup>
</servlet>
<!--设置DispatcherServlet拦截模式 -->
<servlet-mapping>
<servlet-name>springapp</servlet-name>
<url-pattern>*.htm</url-pattern>
</servlet-mapping>
<!--欢迎页-->
<welcome-file-list>
<welcome-file>
index.JSP
</welcome-file>
</welcome-file-list>
<!--标签库 -->
<taglib>
<taglib-uri>fmt</taglib-uri>
<taglib-location>/WEB-INF/lib/fmt.tld</taglib-location>
</taglib>
<taglib>
<taglib-uri>core-rt</taglib-uri>
<taglib-location>/WEB-INF/lib/c-rt.tld</taglib-location>
</taglib>
</web-app>

org.springframework.web.servlet.DispatcherServlet的需要一个名字为web.xml中servlet-name和-servlet.xml的配置文件。本例的为springapp-servlet.xml.

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE beans PUBLIC "-//SPRING//DTD BEAN//EN" "http://www.springframework.org/dtd/spring-beans.dtd">
<!--
- Application context definition for "springapp" DispatcherServlet.
-->
<beans>
<!--对应于web.SpringappController.Java-->
<bean id="springappController" class="web.SpringappController">
<property name="productManager">
<ref bean="prodMan"/>
</property>
</bean>
<!--对应于bus.ProductManager.java-->
<bean id="prodMan" class="bus.ProductManager">
<property name="products">
<list>
<ref bean="product1"/>
<ref bean="product2"/>
<ref bean="product3"/>
</list>
</property>
</bean>
<!--product1,product2,product3为测试样例-->
<bean id="product1" class="bus.Product">
<property name="description"><value>Lamp</value></property>
<property name="price"><value>5.75</value></property>
</bean>

<bean id="product2" class="bus.Product">
<property name="description"><value>Table</value></property>
<property name="price"><value>75.25</value></property>
</bean>
<bean id="product3" class="bus.Product">
<property name="description"><value>Chair</value></property>
<property name="price"><value>22.79</value></property>
</bean>
<!--资源定义-->
<bean id="messageSource" class="org.springframework.context.support.ResourceBundleMessageSource">
<property name="basename"><value>messages</value></property>
</bean>
<!--URL映射配置-->
<bean id="urlMapping" class="org.springframework.web.servlet.handler.SimpleUrlHandlerMapping">
<property name="mappings">
<props>
<prop key="/hello.htm">springappController</prop>
</props>
</property>
</bean>
<!--内部资源视图解析器-->
<bean id="viewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<property name="viewClass"><value>org.springframework.web.servlet.view.JstlView</value></property>
<property name="prefix"><value>/WEB-INF/jsp/</value></property>
<property name="suffix"><value>.jsp</value></property>
</bean>
</beans>

资源文件为messages.properties

title=SpringApp
heading=Hello :: SpringApp
