SpringMVC 项目框架的搭建（javaweb项目）

1、首先创建一个java的mavenweb项目，即选择war包。

2、由于刚创建的web工程缺少web.xml等相关的文件，所以会出现一系列的错误，可以用两种方法去改掉报错。

第一种：手动添加其他java web项目下的下图文件夹（需要包含web.xml文件）放到项目的webapp的文件夹下面

第二种：在项目上右键，最后一个Properties选项，选择Projects  Facets，如下图，在Dynamic Web Module选项上勾选Apply会出现下面的Futher Configuration available的链接，点进去

点进去之后会出现下面的弹出框，上面一个就是项目名不用改，下面一个改成src/main/webapp,然后确定，最后将Dynamic Web Module改成3.0在勾选上确定即会自动在webapp的目录下面创建方法一中的两个文件和其中的web.xml文件。

4、更改pom.xml文件，添加需要的依赖，这里我用的是一个总结版的pom直接放进去

pom.xml

<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.iflytek</groupId><artifactId>myssh</artifactId><version>0.0.1-SNAPSHOT</version><packaging>war</packaging><properties><spring.version>4.3.13.RELEASE</spring.version></properties><dependencies><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-webmvc</artifactId><version>${spring.version}</version></dependency><dependency><groupId>org.springframework</groupId><artifactId>spring-orm</artifactId><version>${spring.version}</version></dependency><dependency><groupId>org.springframework</groupId><artifactId>spring-jdbc</artifactId><version>${spring.version}</version></dependency><dependency><groupId>org.springframework</groupId><artifactId>spring-aop</artifactId><version>${spring.version}</version></dependency><dependency><groupId>org.aspectj</groupId><artifactId>aspectjrt</artifactId><version>1.8.10</version></dependency><dependency><groupId>aopalliance</groupId><artifactId>aopalliance</artifactId><version>1.0</version></dependency><dependency><groupId>org.aspectj</groupId><artifactId>aspectjweaver</artifactId><version>1.8.10</version></dependency><dependency><groupId>org.hibernate</groupId><artifactId>hibernate-core</artifactId><version>4.3.11.Final</version></dependency><!-- web jar --><dependency><groupId>javax.servlet</groupId><artifactId>javax.servlet-api</artifactId><version>3.0.1</version><scope>provided</scope></dependency><dependency><groupId>javax.servlet</groupId><artifactId>jstl</artifactId><version>1.1.2</version><scope>provided</scope></dependency><dependency><groupId>javax.servlet.jsp</groupId><artifactId>javax.servlet.jsp-api</artifactId><version>2.3.1</version><scope>provided</scope></dependency><!-- jstl jar --><!--   * compile，缺省值，适用于所有阶段，会随着项目一起发布。     * provided，类似compile，期望JDK、容器或使用者会提供这个依赖。如servlet.jar。     * runtime，只在运行时使用，如JDBC驱动，适用运行和测试阶段。     * test，只在测试时使用，用于编译和运行测试代码。不会随项目发布。     * system，类似provided，需要显式提供包含依赖的jar，Maven不会在Repository中查找它。  --><dependency><groupId>jstl</groupId><artifactId>jstl</artifactId><version>1.2</version></dependency><dependency><groupId>taglibs</groupId><artifactId>standard</artifactId><version>1.1.2</version></dependency><dependency><groupId>log4j</groupId><artifactId>log4j</artifactId><version>1.2.17</version></dependency><dependency><groupId>com.alibaba</groupId><artifactId>fastjson</artifactId><version>1.2.38</version></dependency><dependency><groupId>com.fasterxml.jackson.core</groupId><artifactId>jackson-core</artifactId><version>2.9.2</version></dependency><dependency><groupId>com.fasterxml.jackson.core</groupId><artifactId>jackson-databind</artifactId><version>2.9.2</version></dependency></dependencies></project>

4、添加spring.xml和springmvc的文件
这里简单配置一下识别注解，没有很完善的功能

spring.xml

<?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:aop="http://www.springframework.org/schema/aop"xmlns:context="http://www.springframework.org/schema/context"xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsdhttp://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.3.xsdhttp://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-4.3.xsd"><context:component-scan base-package="com.iflytek"><context:exclude-filter type="annotation" expression="org.springframework.stereotype.Controller"/></context:component-scan></beans>

springmvc.xml

<?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"xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsdhttp://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.3.xsd"><context:component-scan base-package="com.iflytek"><context:include-filter type="annotation" expression="org.springframework.stereotype.Controller"/></context:component-scan></beans>

5、在web.xml中做相应的配置，将以上Spring.xml和springmvc.xml文件加载到tomcat中，代码如下

<?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_3_0.xsd"id="WebApp_ID" version="3.0"><!-- spring配置文件的路径 --><context-param><param-name>contextConfigLocation</param-name><param-value>classpath:spring.xml</param-value></context-param><servlet><servlet-name>dispatcher</servlet-name><servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class><init-param><param-name>contextConfigLocation</param-name><param-value>classpath:springmvc.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><listener><listener-class>org.springframework.web.context.ContextLoaderListener</listener-class></listener></web-app>

6、编写对应的Controller文件和jsp文件开始你的项目，这里只用了HomeCntroller.java文件和home.jsp文件

HomeController.java

package com.iflytek.controller;import org.springframework.stereotype.Controller;import org.springframework.web.bind.annotation.RequestMapping;@Controllerpublic class HomeController {@RequestMapping("/home")public String goHome() {return "/WEB-INF/jsp/home.jsp";}}

home.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><h1>这里是Home</h1></body></html>

最终在浏览器中的结果如下
