Spring MVC 簡單的hello world的實現
阿新 • • 發佈：2020-01-20
一、專案搭建
1、可以在新建專案的使用Spring MVC框架。或者建立一個簡單的專案之後再用Add Framework Support來新增Spring MVC框架。
2、刪除自動生成的lib的jar包，使用pom檔案來進行管理包。目錄結構如下圖。
3、pom檔案。載入完成之後才能進行下一步。

</project>4、Project Structure的編輯，建立一下包名。
二、webapp的編輯
1、目錄結構。
2、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" xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_4_0.xsd" version="4.0"> <!--welcome pages--> <welcome-file-list> <welcome-file>index.jsp</welcome-file> </welcome-file-list> <context-param> <param-name>contextConfigLocation</param-name> <param-value>/WEB-INF/applicationContext.xml</param-value> </context-param> <listener> <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> </listener> <servlet> <servlet-name>dispatcher</servlet-name> <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> <init-param> <param-name>contextConfigLocation</param-name> <param-value>/WEB-INF/dispatcher-servlet.xml</param-value> </init-param> <load-on-startup>1</load-on-startup> </servlet> <servlet-mapping> <servlet-name>dispatcher</servlet-name> <url-pattern>/</url-pattern> </servlet-mapping> </web-app>
3、applicationContent.xml。
<?xml version="1.0" encoding="UTF-8"?> <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" 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.xsd"> <context:component-scan base-package="com.xiaojie.spring.mvc"/> </beans>
4、dispatcher-servlet.xml。
<?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:context="http://www.springframework.org/schema/context" xmlns:mvc="http://www.springframework.org/schema/mvc" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 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.xsd http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc.xsd"> <context:component-scan base-package="com.xiaojie.spring.mvc"/> <context:annotation-config/> <!-- 配置註解驅動 可以將request引數與繫結到controller引數上 --> <mvc:annotation-driven/> <!--這句要加上，要不然可能會訪問不到靜態資源--> <mvc:default-servlet-handler /> <!--靜態資源對映如下--> <mvc:resources mapping="/css/**" location="/statics/css/"/> <mvc:resources mapping="/js/**" location="/statics/js/"/> <mvc:resources mapping="/image/**" location="/statics/images/"/> <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver"> <property name="prefix" value="/views/"/> <property name="suffix" value=".jsp"/> </bean> </beans>
5、index.jsp預設頁面。
<%@ page contentType="text/html;charset=UTF-8" language="java" %> <html> <head> <title>hello world</title> </head> <body> welcome zhuoxiaojie spring mvc </body> </html>
6、hello.jsp。
<%@ page contentType="text/html;charset=UTF-8" language="java" %> <html> <head> <title>test</title> </head> <body> hello world </body> </html>
7、test2.jsp。
<%@ page contentType="text/html;charset=UTF-8" language="java" %>
<html>
<head>
<title>test</title>
</head>
<body>
key1: ${key1},key2: ${key2}
</body>
</html>
三、Controller層
package com.xiaojie.spring.mvc.controller;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.servlet.ModelAndView;
@Controller
@RequestMapping("/test")
public class TestController {
@RequestMapping("/hello")
public ModelAndView test1(Model model) {
return new ModelAndView("hello");
}
@GetMapping("/test2")
public ModelAndView test2(Model model) {
model.addAttribute("key1","卓小杰");
model.addAttribute("key2","你真帥");
return new ModelAndView("test2");
}
}
四、Tomcat的配置
1、下載Tomcat8。自己去百度教程下載。
2、用Tomcat進行啟動專案的配置。然後啟動專案。
- war模式：將web工程以war包的形式上傳到伺服器
- war exploed模式：將web工程以當前資料夾的位置關係上傳到伺服器
五、測試結果
1、啟動之後的預設介面index.jsp。
2、hello.jsp介面。
3、test2.jsp介面。帶引數。
