当我尝试压缩网址http://localhost:8080/KnockKnocks/welcome.html时，我出现错误HTTP状态404 - /KnockKnocks/welcome.html。

我很感激有人可以帮助我。

此致

Answer 1

使用：

<mvc:annotation-driven />

在你的works-servlet.xml

中

它将您的Spring上下文设置为允许向控制器分派请求。

我希望这会对你有所帮助。

Answer 2

您的示例 works.servlet 显示：

<context:component-scan base-package="com.knockknock.controller" />

但HomeController类中显示的包是：

package com.knockknocks.controller;

你需要那些匹配。前者错过了＆＃39;

。

Answer 3

您的班级HomeController并未映射任何网址：

@Controller
public class HomeController {

    @RequestMapping(name = "/welcome")
    public ModelAndView home(){
        String message = "This is your home";
        return new ModelAndView("welcome", "message", message);
    }
}

您必须将@RequestMapping(name = "/welcome")更改为@RequestMapping(value = "/welcome") 正如document提供的那样，@RequestMapping注释的选项元素：
name: String - 为此映射指定名称 value: String[] - 此注释表示的主要映射 ...
