Question

http://localhost:8080/AnchorMail/可以正常工作并转到index.jsp。

http://localhost:8080/AnchorMail/greeting导致找不到HTTP状态404。

我相信它应该是一个hello JSP页面。我是新手，任何帮助都会非常感激。谢谢。

下面的控制器

   @Controller
    public class HelloController {

        @RequestMapping(value="/greeting")
        public String sayHello(Model model) {

            model.addAttribute("greeting","Hello World");

            return "hello";
        }

}

servlet的config.xml中

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xmlns:context="http://www.springframework.org/schema/context"

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

下面的web.xml

<?xml version="1.0" encoding="UTF-8"?>

Answer 1

请查看此配置元素：

<servlet-mapping>
  <servlet-name>anchorMailServlet</servlet-name>
  <url-pattern>*.html</url-pattern>
</servlet-mapping>

注意您创建的配置。

以* .html结尾的请求将转发到您的spring调度程序servlet。

http://localhost:8080/AnchorMail/greeting未以.html

结尾

另外，请尝试将网址格式更改为/*.html。

Answer 2

@RequestMapping(value="/greeting.html")

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

没有找到Spring MVC http 404，有什么想法？
