java - spring mvc HTTP状态404基本启动

标签 java spring spring-mvc

我无法弄清楚这段代码中的问题是什么。我没有进入主页，控制台中也没有显示错误。

web.xml:

<web-app>
    <display-name>Myapp</display-name>
    <servlet>
        <servlet-name>dispatcher</servlet-name>
        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
    </servlet>
    <servlet-mapping>
        <servlet-name>dispatcher</servlet-name>
        <url-pattern>*.do</url-pattern>
    </servlet-mapping>

</web-app>

调度程序-servlet.xml:

<beans xmlns="http://www.springframework.org/schema/beans"
    xmlns:context="http://www.springframework.org/schema/context"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:mvc="http://www.springframework.org/schema/mvc"
    xsi:schemaLocation="

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

    <bean

        <property name="prefix" value="/WEB-INF/jsp/" />
        <property name="suffix" value=".jsp" />
    </bean>

</beans>

家庭 Controller :

package com.sim.market.controller;

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;

@Controller
@RequestMapping("/home")
public class HomeController {

    public String showHome(){
        System.out.println("calloing");
        return "home";
    }
}

在控制台上没有错误，但在浏览器中错误是

HTTP Status 404 -

type Status report

message

description The requested resource is not available.

当从 eclipse 运行应用程序时，它显示以下日志:

当我调用像 home.do 这样的资源时 它显示:

SLF4J: Failed to load class "org.slf4j.impl.StaticLoggerBinder".
SLF4J: Defaulting to no-operation (NOP) logger implementation
SLF4J: See http://www.slf4j.org/codes.html#StaticLoggerBinder for further details.

最佳答案

那么你应该将其添加到 web.xml

<welcome-file-list>
        <welcome-file>index.jsp</welcome-file>
   </welcome-file-list>

将此代码段添加到index.jsp

<meta HTTP-EQUIV="REFRESH" content="0; url=${pageContext.request.contextPath}/home.do">

每次我在 Spring mvc 中创建应用程序时，我都发现这是一个不错的选择
