我创建了一个简单的Spring框架,其中controller(springapp dispatcherservlet重定向到视图)但它没有重定向到视图..
我得到了index1.jsp的视图,无法获取Redirect.htm / jsp的视图
这是我的代码..

答案 0 :(得分:1)
首先,我将回答您为什么将index1.jsp视为视图的问题。它将在您运行应用程序时向您显示index1.jsp的视图,为什么,因为您已在web.xml中的欢迎文件列表中指定了index1.jsp。 您将无法获取Redirect.jsp,因为您未在 SpringApp-servlet.xml 中配置视图解析程序。 将以下bean添加到 SpringApp-servlet.xml
<bean id="viewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<property name="prefix" value="/WEB-INF/jsp/"/>
<property name="suffix" value=".jsp"/>
</bean>
在prefix属性中,您必须提供Redirect.jsp文件所在的路径(我假设在/ WEB-INF / jsp文件夹中)。 在后缀属性中,您必须指定要解析的视图的扩展名。
更改声明
return new ModelAndView("Redirect.jsp");
到
return new ModelAndView("Redirect");
运行您的应用程序并使用请求/Redirect.htm
现在应该可以了。希望这会有所帮助。
