第一步：配置前端控制器
<filter>
<filter-name>myfilter</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>myfilter</filter-name>
<url-pattern>/</url-pattern>
</filter-mapping>
<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:aplicationContext.xml</param-value>
</init-param>
</servlet>
<servlet-mapping>
<servlet-name>springmvc</servlet-name>
<url-pattern>.do</url-pattern>
</servlet-mapping>
第二步：配置處理器映射器
SimpleUrlHandlerMapping通過id找到Conrtoller
<bean class="org.springframework.web.servlet.handler.SimpleUrlHandlerMapping"></bean>
第三步：配置處理器適配器
HttpRequestHandlerAdapter執(zhí)行Conrtoller
<bean class="org.springframework.web.servlet.mvc.HttpRequestHandlerAdapter"></bean>
第四步：配置視圖解析器
保持不變
<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver"></bean>
第五步：開發(fā)表現(xiàn)層的Action
Action需要實(shí)現(xiàn)HttpRequestHandler接口
public class SecondAction implements HttpRequestHandler {
@Override
public void handleRequest(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
request.setAttribute("secondInfo","這是第二個(gè)案例");
request.getRequestDispatcher("/second.jsp").forward(request,response);
}
}
第六步：配置整合
配置action:這里key是自定義的訪問路徑，節(jié)點(diǎn)值對(duì)應(yīng)就是控制器的ID
首先配置SecondAction
<bean id="mySecondAction" class="com.zyh.action.SecondAction"></bean>
接下來將映射器與相應(yīng)的Action對(duì)應(yīng)起來恒水。
<!--配置處理器映射器-->
<bean class="org.springframework.web.servlet.handler.SimpleUrlHandlerMapping">
<property name="mappings">
<props>
<prop key="/second.do">mySecondAction</prop>
</props>
</property>
</bean>
