基於半註解方式的項目配置
一、創建maven web項目
1.1 創建項目，選擇war打包形式，自動補全包配置
1.2 設置項目的編碼格式爲utf-8
1.3 設置項目的編譯版本爲JDK1.8
1.4 設置項目的服務器爲Tomcat
二、爲項目添加依賴
2.1 配置pom.xml文件，添加spring mvc依賴
<dependencies>
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-webmvc</artifactId>
<version>4.3.9.RELEASE</version>
</dependency>
</dependencies>
2.2 在項目的resource的目錄中添加核心配置文件spring-configs.xml，並進行基礎的配置
<?xml version="1.0" encoding="UTF-8"?>
<beans default-lazy-init="true"
xmlns="http://www.springframework.org/schema/beans"
xmlns:p="http://www.springframework.org/schema/p"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:context="http://www.springframework.org/schema/context"
xmlns:tx="http://www.springframework.org/schema/tx"
xmlns:aop="http://www.springframework.org/schema/aop"
xmlns:mvc="http://www.springframework.org/schema/mvc"
xmlns:util="http://www.springframework.org/schema/util"
xmlns:jpa="http://www.springframework.org/schema/data/jpa"
xsi:schemaLocation="
http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans-4.3.xsd
http://www.springframework.org/schema/mvc
http://www.springframework.org/schema/mvc/spring-mvc-4.3.xsd
http://www.springframework.org/schema/tx
http://www.springframework.org/schema/tx/spring-tx-4.3.xsd
http://www.springframework.org/schema/aop
http://www.springframework.org/schema/aop/spring-aop-4.3.xsd
http://www.springframework.org/schema/util
http://www.springframework.org/schema/util/spring-util-4.3.xsd
http://www.springframework.org/schema/data/jpa
http://www.springframework.org/schema/data/jpa/spring-jpa-1.3.xsd
http://www.springframework.org/schema/context
http://www.springframework.org/schema/context/spring-context-4.3.xsd" >
</beans>
三、配置組件掃描與視圖解析
在spring mvc 核心配置文件中功能組件
<!--配置組件掃描 -->
<context:component-scan base-package="com.jk" />
<!-- 啓用MVC默認配置 (@RequestMapping) -->
<mvc:annotation-driven />
<!-- 配置視圖解析器 -->
<bean id="viewResolver"
class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<property name="prefix" value="/WEB-INF/pages/" />
<property name="suffix" value=".jsp" />
</bean>
四、配置前端控制器
在web.xml文件中配置DispatcherServlet對象
<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" version="2.5">
<display-name>Spring-MVC-02</display-name>
<servlet>
<servlet-name>dispatcherServlet</servlet-name>
<servlet-class>
org.springframework.web.servlet.DispatcherServlet
</servlet-class>
<init-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:spring-configs.xml</param-value>
</init-param>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>dispatcherServlet</servlet-name>
<url-pattern>*.do</url-pattern>
</servlet-mapping>
</web-app>
五、創建後端控制器
在指定的包中創建控制層對象
package com.jk.controller;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.servlet.ModelAndView;
@Controller
@RequestMapping("/req/")
public class AnnotationHelloController{
@RequestMapping("doSayHello")
public ModelAndView doSayHello() {
ModelAndView mv=new ModelAndView("hello");
mv.addObject("message", "helloworld");
return mv;
}
@RequestMapping("doSayWelcome")
public String doSayWelcome() {
return "hello";
}
@RequestMapping("doHandleRequest")
public String doHandleRequest(Model m) {
m.addAttribute("message","welcome to beijing");
return "hello";
}
}
六、創建jsp文件
<%@ page language="java" contentType="text/html; charset=UTF-8"
pageEncoding="UTF-8"%>
<!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=UTF-8">
<title>Insert title here</title>
</head>
<body>
<h1>welcome to here...</h1>
<h1>${ message }</h1>
</body>
</html>
