Spring mvc注解之实现MultiActionController功能

首发地址http://inmethetiger.iteye.com/blog/1679399

熟悉MultiActionController之后，就想写一个基于注解的MultiActionController处理多个用户请求。后来发现，基于注解的多请求处理，并不需要MultiActionController，而只是需要简单的在控制器中使用@Controller并在xxxx-servlet.xml中进行简单的配置就可以了。

　　所以，把代码帖一下，让自己记住。当然，这个只是最简单的实现。只是简单的使用了@RequestMapping，对于参数或者请求参数并没有涉及。主要原因是自己也是菜鸟。有的地方自己也无法解释清楚。　话不多说，代码如下：

-------------------------------------------------------------------------------------------------------------------------------------

 

@Controller
public class MyMutilActionController {
	@RequestMapping(value = "/listing.do")
	public ModelAndView listObject(HttpServletRequest request,
			HttpServletResponse response) {
		ModelAndView mv = new ModelAndView();
		mv.setViewName("list");
		return mv;
	}

	@RequestMapping(value = "/delete.do")
	public ModelAndView deleteObject(HttpServletRequest request,
			HttpServletResponse response) {
		ModelAndView mv = new ModelAndView();
		mv.setViewName("delete");
		return mv;
	}

	@RequestMapping(value = "/update.do")
	public ModelAndView updateObject(HttpServletRequest request,
			HttpServletResponse response) {
		ModelAndView mv = new ModelAndView();
		mv.setViewName("update");
		return mv;
	}

	@RequestMapping(value = "/insert.do")
	public ModelAndView insertObject(HttpServletRequest request,
			HttpServletResponse response) {
		ModelAndView mv = new ModelAndView();
		mv.setViewName("insert");
		return mv;
	}
}

	<!-- 帮助DispatchServlet进行web请求的url到具体处理类的匹配，默认为BeanNameUrlHandleMapping -->

	<!-- <bean id="handlerMapping" class="org.springframework.web.servlet.handler.BeanNameUrlHandlerMapping"> 
		</bean> -->

	<bean id="handlerMapping"
		class="org.springframework.web.servlet.mvc.annotation.DefaultAnnotationHandlerMapping">
	</bean>


	<!-- Controller -->
	<!-- 控制器，自己实现，收集参数，绑定参数到命令对象，调用业务对象，选择视图模型，返回视图，模型，数据 -->
	<!-- <bean name="/login.do" class="org.spring.controller.LoginController"></bean> -->

	<!-- ViewResover -->
	<!-- DispatcherServlet根据Controller中指定的逻辑视图查找相应的视图实现 -->
	<bean id="defaultViewResover"
		class="org.springframework.web.servlet.view.InternalResourceViewResolver">
		<property name="prefix" value="/WEB-INF/view/"></property>
		<property name="suffix" value=".jsp"></property>
	</bean>
</beans>

 

看xml文件可知，基于注解的Spring mvc基本上可以说是零配置。而且方便易懂，比如只要查看控制器就可以知道映射关系，而并不需要在xml文件中查看对应关系。
