我在tomcat，HTTP状态404 /sdnext/save.html
中收到错误请求的资源不可用。我正在尝试使用hibernate执行示例应用程序来学习spring mvc itegration。这是我为样本
尝试的链接http://www.dineshonjava.com/2012/12/spring-mvc-with-hibernate-crud-example.html#.UyihQ_ldWuI
在此，我们没有save.html或add.html或delete.html，但控制器类中提到了这些内容。在示例链接中，这是我使用过的控制器类

答案 0 :(得分：0)
您的问题不是很明确，但如果我理解正确，您希望识别所有网址模式，而不仅仅是html版本。
要做到这一点，请像这样替换web.xml中的url模式。
<url-pattern>/*</url-pattern>
return new ModelAndView("redirect:/add.html");
它表示将请求重定向到特定视图add.html，因此您必须在web-inf文件夹中包含该html文件。
spring处理视图分辨率的方式是在views文件夹中查找匹配的返回视图名称，并选择要渲染的相应视图。
<!-- Resolves views selected for rendering by @Controllers to .jsp resources in the /WEB-INF/views directory -->
<beans:bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<beans:property name="prefix" value="/WEB-INF/views/" />
<beans:property name="suffix" value=".jsp" />
</beans:bean>
这是在弹簧配置的“View Resolver bean”中配置的。我建议你从Spring in action-3rd edition , manning和MVC模型中学习一下spring，了解更多视图分辨率的工作原理。
