[置顶] Intellij IDEA搭建maven+注解SpringMVC框架

本文主要介绍了简单搭建SpringMVC的框架,并未涉及一些原理的讲解，以后会陆续补全，希望可以和大家一起交流进步

本文用到的环境相关版本介绍

本文的tomcat会以maven插件的形式集成至maven

• maven3.2.5
• Intellij IDEA 15
• jdk1.8
• *Spring3.2.4
• tomcat-maven-plugin2.1

一、用maven+Intellij IDEA创建web项目

1.首先新打开IDEA，新建一个project

2.next之后填写一些名称，此处略掉，建完项目之后maven会下载一些依赖，完成之后工程目录如下图：

二、添加jar包依赖

1.在maven仓库中添加一些jar包依赖

<dependencies>

<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-context</artifactId>
<version>3.2.4.RELEASE</version>
</dependency>
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-orm</artifactId>
<version>3.2.4.RELEASE</version>
</dependency>
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-context-support</artifactId>
<version>3.2.4.RELEASE</version>
</dependency>

<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-aspects</artifactId>
<version>3.2.4.RELEASE</version>
</dependency>

<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-test</artifactId>
<version>3.2.4.RELEASE</version>
</dependency>

<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-core</artifactId>
<version>3.2.4.RELEASE</version>
</dependency>

<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-web</artifactId>
<version>3.2.4.RELEASE</version>
</dependency>

<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-webmvc</artifactId>
<version>3.2.4.RELEASE</version>
</dependency>

<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-aop</artifactId>
<version>3.2.4.RELEASE</version>
</dependency>

<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-beans</artifactId>
<version>3.2.4.RELEASE</version>
</dependency>
<!--spring framework end-->

<dependency>
<groupId>org.apache.tomcat</groupId>
<artifactId>tomcat-catalina</artifactId>
<version>7.0.39</version>
<scope>provided</scope>
</dependency>

<dependency>
<groupId>org.apache.tomcat</groupId>
<artifactId>tomcat-coyote</artifactId>
<version>7.0.39</version>
<scope>provided</scope>
</dependency>

</dependencies>

2.将tomcat作为插件放到build节点中

<build>
<finalName>test</finalName>
<plugins>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-war-plugin</artifactId>
<version>2.1.1</version>
</plugin>
<plugin>
<groupId>org.apache.tomcat.maven</groupId>
<artifactId>tomcat7-maven-plugin</artifactId>
<version>2.1</version>
<configuration>
<port>80</port>
<path>/</path>
</configuration>
</plugin>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-compiler-plugin</artifactId>
<version>3.1</version>
<configuration>
<target>1.7</target>
<source>1.7</source>
<encoding>UTF-8</encoding>
<compilerArguments>
<verbose/>
<bootclasspath>${java.home}\lib\rt.jar</bootclasspath>
</compilerArguments>
</configuration>
</plugin>
</plugins>
</build>

三、进行SpringMVC配置

1.首先在resource目录下新建一个spring的配置文件springmvc.xml，文件图片和内容如下

<?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.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd">

<!-- 扫描指定包带@Controller注解的类-->
<context:component-scan base-package="com.myspring.test.controller"></context:component-scan>
<!--视图解析器-->
<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver"/>
</beans>

2.在web.xml配置前端控制器，并加载springmvc.xml的配置文件，内容如下

<!DOCTYPE web-app PUBLIC
 "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN"
 "http://java.sun.com/dtd/web-app_2_3.dtd" >

<web-app>
<display-name>Archetype Created Web Application</display-name>


<!--springMvc前端控制器-->
<servlet>
<servlet-name>SpringMVC</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<!--contextConfigLocation配置springmvc加载的配置文件（配置处理器迎射器、适配器等）-->
<!--如果不配置，则默认加载/WEB-INFO/servlet名称-servlet.xml(springmvc-servlet.xml)-->
<init-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:springmvc.xml</param-value>
</init-param>
</servlet>

<servlet-mapping>
<servlet-name>SpringMVC</servlet-name>
<url-pattern>/</url-pattern>
</servlet-mapping>



</web-app>

3.至此，文件配置完毕，下面我们用注解写一个方法测试一下，测试类放在springmvc.xml配置的扫描的包中，此处包名要与配置文件中扫描的包名一致

测试类中的代码：

@Controller
public class TestController {
@RequestMapping(value = "/admin")
@ResponseBody
public String testSpring(){
return "My testSpring";
    }
}

在maven插件中启动tomcat

在浏览器中访问方法上面的映射地址（@RequestMapping(value = “/admin”)），发现了我们返回的字符串！

至此，用Intellij IDEA搭建maven+注解开发SpringMVC的简单框架已经构建完成！
