错误404:请求的资源[/]不可用

Question

这里的图片有问题

我不明白为什么我得到这个错误。

控制器类:

package com.emusicstore.controller;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
@Controller
public class homeController {
@RequestMapping("/home")
public String home()
{
return "home";
}
}

web . xml:

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns="http://xmlns.jcp.org/xml/ns/javaee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

</servlet>
<servlet-mapping>
<servlet-name>dispatcher</servlet-name>
<url-pattern>/</url-pattern>

</web-app>

dispatcher-servlet

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

</beans>

这是我的home.jsp的位置输入图片描述

任何领导将欣赏

Answer 1

在url模式中使用/*，这样DispatcherServlet就会拦截所有模式为/*的请求，例如/home
