Question

我是Spring框架的新手。我正在处理一个但收到以下错误：

 HTTP Status 404 - /AMController/index.jsp
 ---------------------------
 type Status report
 message /AMController/index.jsp
 description The requested resource is not available.
-------------------------- 
Apache Tomcat/6.0.44

控制器类

@Controller
@RequestMapping("/hello")
public class HelloController {

   @RequestMapping(method = RequestMethod.GET)
   public String printHello(ModelMap model) {
      model.addAttribute("message", "Hello Spring MVC Framework!");
      return "hello";
   }

}

和web.xml

可能是我遗漏了一些我无法弄清楚的事情。请帮我解决这个问题。

HTTP状态404。没找到！

首先，检查设置和路径。

（servlet.xml中）

    <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
      <property name="prefix" value="/WEB-INF/jsp/" />
      <property name="suffix" value=".jsp" />
   </bean>

/ web-inf / jsp /（前缀）+“文件名”+ .jsp（后缀）

此文件夹结构。

添加int xml

<listener>
    <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>

（控制器）

@Controller
@RequestMapping("/hello")
public class HelloController {

   @RequestMapping(value = "/print/hello" ,method = RequestMethod.GET)
   public String printHello(ModelMap model) {
      model.addAttribute("message", "Hello Spring MVC Framework!");
      return "/hello";
   }
}

您在浏览器中输入了一个网址。

localhost：主机/上下文路径，web app项目名称/ hello / print / hello

HTTP状态404 - 在Spring MVC控制器中
