以下示例显示了如何使用Spring Web MVC框架使用Multi Action Controller的Properties Method Name Resolver方法。 MultiActionController类有助于分别在单个控制器中映射多个URL及其方法。
package com.tutorialspoint;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import org.springframework.web.servlet.ModelAndView;
import org.springframework.web.servlet.mvc.multiaction.MultiActionController;
public class UserController extends MultiActionController{
public ModelAndView home(HttpServletRequest request,
HttpServletResponse response) throws Exception {
ModelAndView model = new ModelAndView("user");
model.addObject("message", "Home");
return model;
}
public ModelAndView add(HttpServletRequest request,
HttpServletResponse response) throws Exception {
ModelAndView model = new ModelAndView("user");
model.addObject("message", "Add");
return model;
}
public ModelAndView remove(HttpServletRequest request,
HttpServletResponse response) throws Exception {
ModelAndView model = new ModelAndView("user");
model.addObject("message", "Remove");
return model;
}
}
home
add
update
例如,使用以上配置,如果URI-
/user/home.htm被请求,DispatcherServlet会将请求转发到UserController home()方法。
/user/add.htm被请求,DispatcherServlet会将请求转发到UserController的add()方法。
/user/remove.htm被请求时,DispatcherServlet会将请求转发到UserController的remove()方法。
首先,让我们拥有一个运行良好的Eclipse IDE,并考虑以下步骤,以使用Spring Web Framework开发基于动态表单的Web应用程序。
Step | Description |
---|---|
1 | Create a project with a name TestWeb under a package com.tutorialspoint as explained in the Spring MVC – Hello World chapter. |
2 | Create Java class UserController under the com.tutorialspoint package. |
3 | Create a view file user.jsp under the jsp sub-folder. |
4 | The final step is to create the content of the source and configuration files and export the application as explained below. |
package com.tutorialspoint;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import org.springframework.web.servlet.ModelAndView;
import org.springframework.web.servlet.mvc.multiaction.MultiActionController;
public class UserController extends MultiActionController{
public ModelAndView home(HttpServletRequest request,
HttpServletResponse response) throws Exception {
ModelAndView model = new ModelAndView("user");
model.addObject("message", "Home");
return model;
}
public ModelAndView add(HttpServletRequest request,
HttpServletResponse response) throws Exception {
ModelAndView model = new ModelAndView("user");
model.addObject("message", "Add");
return model;
}
public ModelAndView remove(HttpServletRequest request,
HttpServletResponse response) throws Exception {
ModelAndView model = new ModelAndView("user");
model.addObject("message", "Remove");
return model;
}
}
home
add
update
Hello World
${message}
完成创建源文件和配置文件后,导出应用程序。右键单击您的应用程序,使用“导出”→“ WAR文件”选项,并将TestWeb.war文件保存在Tomcat的webapps文件夹中。
现在,启动Tomcat服务器,并确保您能够使用标准浏览器从webapps文件夹访问其他网页。现在,尝试使用URL- http:// localhost:8080 / TestWeb / user / add.htm ,如果Spring Web Application一切正常,我们将看到以下屏幕。
