SpringMVC之HanderMapping-3種訪問Controller的方式
阿新 • • 發佈：2018-11-07
1、根據beanname找到對應Conntroller
<!-- 配置HandlerMapping 根據benaname找到對應Conntroller--> <bean class="org.springframework.web.servlet.mvc.support.ControllerBeanNameHandlerMapping"></bean> 配置Controller <bean name="/user.do" class="com.xfh.controler.UserController"></bean>
2、根據簡單URL查詢Controller
<!-- 根據簡單URL查詢Controller -->
<bean class="org.springframework.web.servlet.handler.SimpleUrlHandlerMapping">
<property name="mappings">
<props>
<prop key="/userInfo.do">userController</prop>
</props>
</property>
</bean>
<bean id="userController" name="/user.do" class="com.xfh.controler.UserController"></bean> 3、根據控制類的類名訪問Controller,訪問時類的類名需要小寫
<!--根據控制類的類名訪問Controller,訪問時類的類名需要小寫 -->
<bean class="org.springframework.web.servlet.mvc.support.ControllerClassNameHandlerMapping"></bean>
<bean class="com.xfh.controler.UserController"></bean>UserController:
/**
* 控制器
*/
public class UserController extends AbstractController {
@Override
protected ModelAndView handleRequestInternal(HttpServletRequest request,
HttpServletResponse response) throws Exception {
System.out.println("===訪問到了===");
return null;
}
}user.jsp:
<body>
<a href="user.do">根據BeanName訪問Controller</a><br>
<a href="userInfo.do">根據URL訪問Controller</a><br>
<a href="userController.do">根據Controller類名訪問Controller</a><br>
</body>
<servlet>
<servlet-name>springmvc</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>springmvc</servlet-name>
<url-pattern>*.do</url-pattern>
</servlet-mapping>
