How to set the welcome page in a spring MVC application other than WEB-INF folder?
问题
这是我的应用程序的目录结构。我已经突出显示了 welcome.jsp 文件（直接位于 WEB-INF 文件夹中）。
web.xml 文件：
<!DOCTYPE web-app PUBLIC
"-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN"
"http://java.sun.com/dtd/web-app_2_3.dtd">
<web-app>
<display-name>Archetype Created Web Application</display-name>
<servlet>
<servlet-name>subu</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>subu</servlet-name>
<url-pattern>/</url-pattern>
</servlet-mapping>
<welcome-file-list>
<welcome-file>welcome.jsp</welcome-file>
</welcome-file-list>
</web-app>
subu-servlet.xml 文件：
<?xml version="1.0" encoding="UTF-8"?>

<property name="suffix" value=".jsp"/>
</bean>
</beans>
welcome.jsp 文件：
<html>
<h1>Welcome page !!!!!!!!</h1>
<body>
<form action="add">
<input type="text" name="t1"><br>
<input type="text" name="t2"><br>
<input type="submit">
</form>
</body>
</html>
在 com.controller 包下的 AddController.java 文件：
package com.controller;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.servlet.ModelAndView;
import com.service.AddService;
@Controller
public class AddController
{
@RequestMapping("/add")
public ModelAndView add(HttpServletRequest request,HttpServletResponse res)
{
int i=Integer.parseInt(request.getParameter("t1"));
int j=Integer.parseInt(request.getParameter("t2"));
AddService as=new AddService();
int k=as.add(i, j);
ModelAndView mv=new ModelAndView();//需要指定两个内容，视图名称和要传递的数据
mv.setViewName("display");
mv.addObject("result",k);
return mv;
}
}

return mv;
}
}

- 请将以下代码添加到应用配置文件中：
<mvc:view-controller path="/" view-name="yourviewPage"/>。这样，根路径将解析为yourviewPage视图。
您可以将 path 的值更改为 welcomepath。
- 然后，将以下代码添加到应用配置文件中：
<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<property name="prefix" value="/WEB-INF/views/"/>
<property name="suffix" value=".jsp"/>
</bean>
这将会将视图解析为 /WEB-INF/views/yourviewPage.jsp。
英文:
- Please add
<mvc:view-controller path="/" view-name="yourviewPage"/>to the application config file. Then the ROOT will resolve to the yourviewPage view.
You can change the path value to the welcomepath
- Then add
<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<property name="prefix" value="/WEB-INF/views/"/>
<property name="suffix" value=".jsp"/>
</bean>
to the applicationconfig file. This will resolve the view to /WEB-INF/view/yourviewPage.jsp.
