一喊暖、如何利用idea創(chuàng)建一個maven web項(xiàng)目？
1议薪、file -- new -- project

2、選擇maven的web模板

3媳友、一些配置

一直點(diǎn)next斯议，這樣一個空的web工程就創(chuàng)建好了
4、創(chuàng)建好的web工程目錄結(jié)構(gòu)

5醇锚、補(bǔ)齊缺失的目錄文件夾（看圖操作）

6哼御、引入必要的依賴
6.1、引入springmvc的pom依賴
<properties>
<project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
<maven.compiler.source>1.7</maven.compiler.source>
<maven.compiler.target>1.7</maven.compiler.target>
<spring.version>4.0.6.RELEASE</spring.version>
</properties>

6.2焊唬、引入jackson依賴恋昼，沒有這個jackson，使用@ResponseBody注解會報(bào)416錯誤
<!-- jackson -->

<groupId>com.alibaba</groupId>
<artifactId>fastjson</artifactId>
<version>1.2.28</version>
</dependency>
6.3赶促、如何引入本地jar包依賴
6.3.1 jar包一定要放在WEB-INf下的lib目錄下液肌，否則會報(bào)NoClassDefFoundError（這個是編譯正常，運(yùn)行時找不到正確的jar包）
6.3.2 pom依賴的正確寫法
<!-- 添加串口通信 -->
<dependency>
<groupId>org.rxtx</groupId>
<artifactId>rxtx</artifactId>
<version>2.2</version>
<scope>system</scope>
<systemPath>${basedir}/src/main/webapp/WEB-INF/lib/rxtx-2.2.jar</systemPath>
</dependency>
7芳杏、web.xml的配置
7.1 添加springmvcfilter矩屁，所有請求都交給spring容器處理
<!-- springmvc -->
<servlet>
<servlet-name>springmvc</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<init-param>
<param-name>contextConfigLocation</param-name>
<param-value>
classpath:spring/spring-mvc-servlet.xml
</param-value>
</init-param>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>springmvc</servlet-name>
<url-pattern>/</url-pattern>
</servlet-mapping>
7.2 如果要使用applicationContext.getBean(beanName)的方式獲取bean要添加如下配置
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:spring/spring-mvc-servlet.xml</param-value>
</context-param>
<!-- 添加spring上下文 -->
<listener>
<listener-class>com.shangda.message.listener.SuperContextLoaderListener</listener-class>
</listener>
注：spring/spring-mvc-servlet.xml這個文件在下圖目錄下
