eclipse+maven搭建SpringMVC项目

step1 准备工具

 

1. jdk
2. Tomcat
3. maven
4. eclipse

工具的安装和配置就不说了。

step2 创建maven project

在eclipse中file->new->project->maven->maven project

 

step2 配置文件

1.配置maven依赖，编辑pom.xml文件

<project xmlns="http://maven.apache.org/POM/4.0.0"
	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
	xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
	<modelVersion>4.0.0</modelVersion>
	<groupId>com.kyle</groupId>
	<artifactId>demo</artifactId>
	<version>0.0.1-SNAPSHOT</version>
	<packaging>war</packaging>
	<name>demo</name>
	
	<properties>
        <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
        <spring.version>4.2.6.RELEASE</spring.version>
    </properties>

    <dependencies>
        <!-- springframework 4 dependencies begin -->
        <dependency>
            <groupId>org.springframework</groupId>
            <artifactId>spring-core</artifactId>
            <version>${spring.version}</version>
        </dependency>
        <dependency>
            <groupId>org.springframework</groupId>
            <artifactId>spring-context</artifactId>
            <version>${spring.version}</version>
        </dependency>
        <dependency>
            <groupId>org.springframework</groupId>
            <artifactId>spring-web</artifactId>
            <version>${spring.version}</version>
        </dependency>
        <dependency>
            <groupId>org.springframework</groupId>
            <artifactId>spring-webmvc</artifactId>
            <version>${spring.version}</version>
        </dependency>
        <dependency>
            <groupId>org.springframework</groupId>
            <artifactId>spring-orm</artifactId>
            <version>${spring.version}</version>
        </dependency>
    </dependencies>
<!-- springframework 4 dependencies end -->
	
</project>

2. 在src/main/java 的 com.kyle 包下创建HelloController.java ，com.kyle是我的groupId
 

package com.kyle;

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

@Controller //控制器注解
@RequestMapping(value = "/") //截获所有路径的请求
public class HelloController {
	@RequestMapping(value = "/hello")
	public String hello(Model model) {
		model.addAttribute("message","pagie");
		return "hello";

	}
}

3. 在WIB-INF目录下，创建一个demo-servlet.xml文件，用来配置springMVC，文件名随便取，后缀是-servlet.xml就行

<?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:p="http://www.springframework.org/schema/p"   
    xmlns:context="http://www.springframework.org/schema/context"   
    xmlns:mvc="http://www.springframework.org/schema/mvc"   
    xmlns:task="http://www.springframework.org/schema/task"  
    xsi:schemaLocation="  
        http://www.springframework.org/schema/beans   
        http://www.springframework.org/schema/beans/spring-beans-4.2.xsd   
        http://www.springframework.org/schema/context   
        http://www.springframework.org/schema/context/spring-context-4.2.xsd   
        http://www.springframework.org/schema/mvc   
        http://www.springframework.org/schema/mvc/spring-mvc-4.2.xsd   
        http://www.springframework.org/schema/task   
        http://www.springframework.org/schema/task/spring-task-4.2.xsd">  

    <!-- 对web包中的所有类进行扫描，以完成Bean创建和自动依赖注入的功能 -->
    <context:component-scan base-package="com.kyle" />

    <!-- 激活基于注解的配置 @RequestMapping, @ExceptionHandler,数据绑定 ,@NumberFormat ,  
    @DateTimeFormat ,@Controller ,@Valid ,@RequestBody ,@ResponseBody等  -->  
    <mvc:annotation-driven />  

    <!-- 视图层配置 -->  
    <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">  
        <property name="prefix" value="/WEB-INF/view/"/>  
        <property name="suffix" value=".jsp"/>  
    </bean>  
</beans>

4.配置web.xml文件，如果创建maven项目没有生产web.xml文件，右键项目下的Deployment Descriptor，选择Generate Deployment Descriptor Stub，生成web.xml文件

<?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>demo</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>
  
  <!-- 请求都交给DispatcherServlet处理 --> 
  <servlet>
        <servlet-name>demo</servlet-name>
        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
        <load-on-startup>1</load-on-startup> 
   </servlet>

      <!-- 拦截所有请求 -->  
    <servlet-mapping>    
        <servlet-name>demo</servlet-name>
        <url-pattern>/</url-pattern>    
    </servlet-mapping>
</web-app>

5. 在WEB-INF下创建view文件夹，在此文件夹下创建一个hello.jsp

<%@ 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>
    ${message}
</body>
</html>

 

step4 启动Server，访问http://localhost:8080/demo/hello页面，图就不截了
