1.首先要引入jar包

  1  <!--引入beans節點-->  2     <dependency>  3       <groupId>org.springframework</groupId>  4       <artifactId>spring-beans</artifactId>  5       <version>4.2.3.RELEASE</version>  6     </dependency>  7   8   9     <dependency> 10       <groupId>org.springframework</groupId> 11       <artifactId>spring-context</artifactId> 12       <version>4.2.0.RELEASE</version> 13     </dependency> 14  15     <dependency> 16       <groupId> org.aspectj</groupId > 17       <artifactId> aspectjweaver</artifactId > 18       <version> 1.8.7</version > 19     </dependency> 20  21     <!--SpringWebMVC--> 22     <!-- https://mvnrepository.com/artifact/org.springframework/spring-webmvc --> 23     <dependency> 24       <groupId>org.springframework</groupId> 25       <artifactId>spring-webmvc</artifactId> 26       <version>3.1.2.RELEASE</version> 27     </dependency> 28  29  30  31     <!--ServletAPI--> 32     <dependency> 33       <groupId>javaee</groupId> 34       <artifactId>javaee-api</artifactId> 35       <version>5</version> 36     </dependency> 37  38     <dependency> 39       <groupId>javax.servlet</groupId> 40       <artifactId>jstl</artifactId> 41       <version>1.2</version> 42       <scope>runtime</scope> 43     </dependency> 44  45  46     <!--SpringWeb--> 47     <dependency> 48       <groupId>org.springframework</groupId> 49       <artifactId>spring-web</artifactId> 50       <version>4.1.8.RELEASE</version> 51     </dependency> 52  53  54     <!--alibaba的 fastjson--> 55     <dependency> 56       <groupId>com.alibaba</groupId> 57       <artifactId>fastjson</artifactId> 58       <version>1.2.31</version> 59     </dependency> 60  61     <!-- https://mvnrepository.com/artifact/com.fasterxml.jackson.core/jackson-core --> 62     <dependency> 63       <groupId>com.fasterxml.jackson.core</groupId> 64       <artifactId>jackson-core</artifactId> 65       <version>2.8.1</version> 66     </dependency> 67  68     <dependency> 69       <groupId>com.fasterxml.jackson.core</groupId> 70       <artifactId>jackson-databind</artifactId> 71       <version>2.5.1</version> 72     </dependency> 73  74     <!--資料驗證--> 75     <dependency> 76       <groupId>org.hibernate</groupId> 77       <artifactId>hibernate-validator</artifactId> 78       <version>4.0.1.GA</version> 79     </dependency> 80  81     <!--jboss logging--> 82     <dependency> 83       <groupId>org.jboss.logging</groupId> 84       <artifactId>jboss-logging</artifactId> 85       <version>3.3.0.Final</version> 86     </dependency> 87  88     <!--validation api--> 89     <dependency> 90       <groupId>javax.validation</groupId> 91       <artifactId>validation-api</artifactId> 92       <version>1.0.0.GA</version> 93     </dependency> 94  95     <!--slf4j api--> 96     <dependency> 97       <groupId>org.slf4j</groupId> 98       <artifactId>slf4j-api</artifactId> 99       <version>1.7.21</version>100     </dependency>101 102     <!--檔案上傳的jar包-->103     <dependency>104       <groupId>commons-fileupload</groupId>105       <artifactId>commons-fileupload</artifactId>106       <version>1.3.1</version>107     </dependency>108 109     <dependency>110       <groupId>commons-io</groupId>111       <artifactId>commons-io</artifactId>112       <version>1.4</version>113     </dependency>114     <dependency>115       <groupId>org.apache.poi</groupId>116       <artifactId>poi</artifactId>117       <version>3.17-beta1</version>118     </dependency>119 120   </dependencies>

2.填寫web.xml

 1 <web-app> 2   <display-name>Archetype Created Web Application</display-name> 3   <!--配置前端控制器--> 4   <servlet> 5     <servlet-name>stringmvc</servlet-name> 6     <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> 7     <!--初始化參數--> 8  <init-param> 9    <param-name>contextConfigLocation</param-name>10    <param-value>classpath:springmvc.xml</param-value>11  </init-param>12 13     <!--只要Tomcat一啟動，就將servlet對象建立好放入記憶體了-->14     <load-on-startup>1</load-on-startup>15 16   </servlet>17   18   <servlet-mapping>19     <servlet-name>stringmvc</servlet-name>20     <url-pattern>/</url-pattern>21   </servlet-mapping>22 </web-app>

View Code

3.寫springmvc.xml

 1 <?xml version="1.0" encoding="UTF-8"?> 2 <beans xmlns="http://www.springframework.org/schema/beans" 3        xmlns:aop="http://www.springframework.org/schema/aop" 4        xmlns:context="http://www.springframework.org/schema/context" 5        xmlns:tx="http://www.springframework.org/schema/tx" 6        xmlns:mvc="http://www.springframework.org/schema/mvc" 7        xmlns:p="http://www.springframework.org/schema/p" 8        xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 9        xsi:schemaLocation="10         http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd11         http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop.xsd12         http://www.springframework.org/schema/context  http://www.springframework.org/schema/context/spring-context.xsd13         http://www.springframework.org/schema/tx  http://www.springframework.org/schema/tx/spring-tx.xsd14         http://www.springframework.org/schema/mvc   http://www.springframework.org/schema/mvc/spring-mvc.xsd15 ">16     <!--註冊處理器-->17     <bean id="/hello.do" class="cn.happy.controller.FirstController"></bean>18 </beans>

View Code

4.建立類編寫代碼

 1 /*控制器 2 * ModelAndView 3 * handleRequest 4 * */ 5 public class FirstController implements Controller{ 6     public ModelAndView handleRequest(HttpServletRequest httpServletRequest, HttpServletResponse httpServletResponse) throws Exception { 7         ModelAndView mv=new ModelAndView(); 8         mv.setViewName("/WEB-INF/index.jsp"); 9         return mv;10     }11 }

View Code

5.在WEB-INF下寫一個jsp

1 <%@ page contentType="text/html;charset=UTF-8" language="java" %>2 <html>3 <head>4     <title>Title</title>5 </head>6 <body>7 <h2>StringMVC  One</h2>8 </body>9 </html>

View Code
