1、添加依赖，并在项目上添加Spring mvc框架的支持（add FrameWork Support）：
1 <dependency> 2 <groupId>junit</groupId> 3 <artifactId>junit</artifactId> 4 <version>4.12</version> 5 <scope>test</scope> 6 </dependency> 7 <!--日志--> 8 <dependency> 9 <groupId>org.slf4j</groupId> 10 <artifactId>slf4j-log4j12</artifactId> 11 <version>1.7.21</version> 12 </dependency> 13 <!--J2EE--> 14 <dependency> 15 <groupId>javax.servlet</groupId> 16 <artifactId>javax.servlet-api</artifactId> 17 <version>3.1.0</version> 18 </dependency> 19 <dependency> 20 <groupId>javax.servlet.jsp</groupId> 21 <artifactId>jsp-api</artifactId> 22 <version>2.2</version> 23 </dependency> 24 <dependency> 25 <groupId>javax.servlet</groupId> 26 <artifactId>jstl</artifactId> 27 <version>1.2</version> 28 </dependency> 29 <!--mysql驱动包--> 30 <dependency> 31 <groupId>mysql</groupId> 32 <artifactId>mysql-connector-java</artifactId> 33 <version>5.1.35</version> 34 </dependency> 35 <!--springframework--> 36 <dependency> 37 <groupId>org.springframework</groupId> 38 <artifactId>spring-web</artifactId> 39 <version>4.2.6.RELEASE</version> 40 </dependency> 41 <dependency> 42 <groupId>org.springframework</groupId> 43 <artifactId>spring-webmvc</artifactId> 44 <version>4.2.6.RELEASE</version> 45 </dependency> 46 <dependency> 47 <groupId>org.springframework</groupId> 48 <artifactId>spring-context</artifactId> 49 <version>4.2.6.RELEASE</version> 50 </dependency> 51 <dependency> 52 <groupId>org.springframework</groupId> 53 <artifactId>spring-test</artifactId> 54 <version>4.2.6.RELEASE</version> 55 </dependency> 56 <dependency> 57 <groupId>org.springframework</groupId> 58 <artifactId>spring-jdbc</artifactId> 59 <version>4.2.6.RELEASE</version> 60 </dependency> 61 <dependency> 62 <groupId>com.github.stefanbirkner</groupId> 63 <artifactId>system-rules</artifactId> 64 <version>1.16.1</version> 65 <scope>test</scope> 66 </dependency> 67 <dependency> 68 <groupId>org.aspectj</groupId> 69 <artifactId>aspectjweaver</artifactId> 70 <version>1.8.9</version> 71 </dependency> 72 <!--其他需要的包--> 73 <dependency> 74 <groupId>org.apache.commons</groupId> 75 <artifactId>commons-lang3</artifactId> 76 <version>3.4</version> 77 </dependency> 78 <dependency> 79 <groupId>commons-fileupload</groupId> 80 <artifactId>commons-fileupload</artifactId> 81 <version>1.3.1</version> 82 </dependency>
2、配置web.xml
1 <?xml version="1.0" encoding="UTF-8"?> 2 <web-app xmlns="http://xmlns.jcp.org/xml/ns/javaee" 3 xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 4 xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_3_1.xsd" 5 version="3.1"> 6 7 <display-name>Archetype Created Web Application</display-name> 8 9 <!--welcome pages--> 10 <welcome-file-list> 11 <welcome-file>index.jsp</welcome-file> 12 </welcome-file-list> 13 14 <!--配置springmvc DispatcherServlet--> 15 <servlet> 16 <servlet-name>springMVC</servlet-name> 17 <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> 18 <init-param> 19 <!--配置dispatcher.xml作为mvc的配置文件--> 20 <param-name>contextConfigLocation</param-name> 21 <param-value>/WEB-INF/dispatcher-servlet.xml</param-value> 22 </init-param> 23 <load-on-startup>1</load-on-startup> 24 <async-supported>true</async-supported> 25 </servlet> 26 <servlet-mapping> 27 <servlet-name>springMVC</servlet-name> 28 <url-pattern>/</url-pattern> 29 </servlet-mapping> 30 <!--把applicationContext.xml加入到配置文件中--> 31 <context-param> 32 <param-name>contextConfigLocation</param-name> 33 <param-value>/WEB-INF/applicationContext.xml</param-value> 34 </context-param> 35 <listener> 36 <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> 37 </listener> 38 </web-app>
3、配置dispatcher-servlet.xml
1 <?xml version="1.0" encoding="UTF-8"?> 2 <beans xmlns="http://www.springframework.org/schema/beans" 3 xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 4 xmlns:context="http://www.springframework.org/schema/context" 5 xmlns:mvc="http://www.springframework.org/schema/mvc" 6 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 http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc.xsd"> 7 <!--此文件负责整个mvc中的配置--> 8 9 <!--启用spring的一些annotation --> 10 <context:annotation-config/> 11 12 <!-- 配置注解驱动 可以将request参数与绑定到controller参数上 --> 13 <mvc:annotation-driven/> 14 15 <!--静态资源映射--> 16 <!--本项目把静态资源放在了webapp的statics目录下，资源映射如下--> 17 <mvc:resources mapping="/css/**" location="/WEB-INF/statics/css/"/> 18 <mvc:resources mapping="/js/**" location="/WEB-INF/statics/js/"/> 19 <mvc:resources mapping="/image/**" location="/WEB-INF/statics/image/"/> 20 21 <!-- 对模型视图名称的解析，即在模型视图名称添加前后缀(如果最后一个还是表示文件夹,则最后的斜杠不要漏了) 使用JSP--> 22 <!-- 默认的视图解析器 在上边的解析错误时使用 (默认使用html)- --> 23 <bean id="defaultViewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver"> 24 <property name="viewClass" value="org.springframework.web.servlet.view.JstlView"/> 25 <property name="prefix" value="/WEB-INF/views/"/><!--设置JSP文件的目录位置--> 26 <property name="suffix" value=".jsp"/> 27 <property name="exposeContextBeansAsAttributes" value="true"/> 28 </bean> 29 30 <!-- 自动扫描装配 --> 31 <context:component-scan base-package="example.controller"/> 32 </beans>
4、配置applicationContext.xml
1 <?xml version="1.0" encoding="UTF-8"?> 2 <beans xmlns="http://www.springframework.org/schema/beans" 3 xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 4 xmlns:context="http://www.springframework.org/schema/context" 5 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"> 6 <context:component-scan base-package="example"/> 7 </beans>
5、编写controller
1 @Controller 2 @RequestMapping("/home") 3 public class IndexController { 4 5 @RequestMapping("/index") 6 public String index() { 7 return "index"; 8 } 9 }
6、在WEB-INF下建立views文件夹，并在这个文件夹下建立文件test.jsp
7、运行调试；
