搭建springmvc

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>1234567891011121314151617181920212223242526272829303132333435363738394041424344454647484950515253545556575859606162636465666768697071727374757612345678910111213141516171819202122232425262728293031323334353637383940414243444546474849505152535455565758596061626364656667686970717273747576

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>123456789101112131415161718192021222324252627282930313233123456789101112131415161718192021222324252627282930313233

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>12345678910111234567891011

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>1234567891011121314151617181920212223242526272812345678910111213141516171819202122232425262728

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：

@Controllerpublic class TestController {     @RequestMapping(value = "/admin")    @ResponseBody     public String testSpring(){        return "My testSpring";     } }1234567812345678

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！
