Question

我正在构建一个Spring MVC应用程序;我正在使用Spring Tool Suite 3.6.4和TomCat8。当我运行网络应用时，当我访问 /问候时，我在控制台中收到“Http Status 404请求的资源不可用”，我有既没有错误< / strong>也不是我使用System.out.println显示的消息。

在我的代码下面。请帮忙

的web.xml

<?xml version="1.0" encoding="UTF-8"?> <web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://xmlns.jcp.org/xml/ns/javaee" xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_3_1.xsd" id="WebApp_ID" version="3.1"> <display-name>fitTracker</display-name> <welcome-file-list> <welcome-file>index.html</welcome-file> <welcome-file>index.htm</welcome-file> <welcome-file>index.jsp</welcome-file> <welcome-file>default.html</welcome-file> <welcome-file>default.htm</welcome-file> <welcome-file>default.jsp</welcome-file> </welcome-file-list> <servlet> <description></description> <display-name>fitness</display-name> <servlet-name>fitness</servlet-name> <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> </servlet> <servlet-mapping> <servlet-name>fitness</servlet-name> <url-pattern>/*</url-pattern> </servlet-mapping> </web-app

健身servlet.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" xmlns:mvc="http://www.springframework.org/schema/mvc" xmlns:p="http://www.springframework.org/schema/p" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.1.xsd http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-4.1.xsd"> <mvc:annotation-driven/> <mvc:default-servlet-handler/> <context:annotation-config/> <context:component-scan base-package="com.thewizardofoz.controllers.controllers"/> <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver" p:prefix="/WEB-INF/jsp/" p:suffix=".jsp" /> </beans>

HelloController.java

package com.thewizardofoz.controllers; import org.springframework.stereotype.Controller; import org.springframework.ui.Model; import org.springframework.web.bind.annotation.RequestMapping; @Controller public class HelloController { @RequestMapping(value="/greeting") public String sayHello(Model model){ System.out.println("Hello Console"); model.addAttribute("greeting", "Welcome to our world!"); return "hello"; } }

的hello.jsp

<%@ page language="java" contentType="text/html; charset=ISO-8859-1" pageEncoding="ISO-8859-1"%> <!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"> <html> <head> <meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1"> <title>Insert title here</title> </head> <body> <h1>${greeting}</h1> </body> </html>

的index.jsp

<%@ page language="java" contentType="text/html; charset=ISO-8859-1" pageEncoding="ISO-8859-1"%> <!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"> <html> <head> <meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1"> <title>Insert title here</title> </head> <body> <h1>INDEX</h1> </body> </html>

Answer 1

您<context:component-scan/>扫描包com.thewizardofoz.controllers.controllers，但您的控制器位于包com.thewizardofoz.controllers

将其更改为

<context:component-scan base-package="com.thewizardofoz.controllers"/>

它应该有效

Answer 2

请更改标签：

<context:component-scan base-package="com.thewizardofoz.controllers.controllers"/>

到

<context:component-scan base-package="com.thewizardofoz.controllers"/>
