我是Spring Framework的新手，并尝试构建一个测试项目来了解它是如何工作的。根据本教程Netbeans tutorial，请参阅下面的代码。

感谢您提供任何帮助。
答案 0 :(得分：0)
根据映射和配置，您应该在WEB-INF/jsp文件夹中包含jsp文件。
setSuccessView("helloView");
在上面的代码中helloView根据前缀和后缀规则转换为WEB-INF/jsp/helloView.jsp，dispatcher-servelt.xml在viewResolver定义。
<bean id="viewResolver"
class="org.springframework.web.servlet.view.InternalResourceViewResolver"
p:prefix="/WEB-INF/jsp/"
p:suffix=".jsp" />
确保helloView.jsp文件夹下有WEB-INF/jsp。同样适用于hello。
根据配置，您已为index.htm定义了控制器。如果您不希望弹簧hello.htm进入画面，请对InternalResourceViewResolver应用相同的内容。
<prop key="index.htm">indexController</prop>
