springmvc web项目搭建

开发环境

myeclipse+maven+tomcat

步骤

1.创建maven项目

然后两次next



继续next



将项目的gourpId，artifactId，版本填写好，点击finish。maven项目创建完成

2.将maven项目转为web项目

在main下新建文件夹webapp



选中项目，右键



点击Browse，选择刚才创建的webapp文件夹，部署路径一栏自己命名，然后点击finish，项目就转为一个web项目



打开webapp文件夹，web项目的配置文件已经创建好了

3.配置pom.xml

因为是基于springmvc的web项目，并且页面需要用到jstl标签，所以需要增加如下依赖，

<properties>
                      <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
                      <spring.version>3.2.4.RELEASE</spring.version>
                      <jstl.version>1.2</jstl.version>
               </properties>

<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-webmvc</artifactId>
<version>${spring.version}</version>
</dependency>

<!-- jsp页面引用jstl所需要 -->
<dependency>
<groupId>jstl</groupId>
<artifactId>jstl</artifactId>
<version>${jstl.version}</version>
</dependency>

修改packaging标签为war

<packaging>war</packaging>

4.配置web.xml

在main下创建resources文件夹，并且配置为Source



在resources下新建applicationContext.xml，具体内容如下

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:aop="http://www.springframework.org/schema/aop" xmlns:mvc="http://www.springframework.org/schema/mvc"
xmlns:context="http://www.springframework.org/schema/context"
xmlns:util="http://www.springframework.org/schema/util" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:p="http://www.springframework.org/schema/p" xmlns:task="http://www.springframework.org/schema/task"
xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-3.0.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-3.0.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.0.xsd http://www.springframework.org/schema/util http://www.springframework.org/schema/util/spring-util-3.0.xsd http://www.springframework.org/schema/task http://www.springframework.org/schema/task/spring-task-3.0.xsd"> 
<context:component-scan base-package="com.henry" />
<mvc:annotation-driven />

</beans>

继续在resources下新建dispatcher.xml,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:p="http://www.springframework.org/schema/p"
xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd"> 
<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver"
p:prefix="/views/"
p:suffix=".jsp"/>
</beans>

上面两个文件新增完成后，配置web.xml

<?xml version="1.0" encoding="UTF-8"?>
<web-app version="2.5" xmlns="http://java.sun.com/xml/ns/javaee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"> 
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:applicationContext.xml</param-value>
</context-param>
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>

<servlet>
<servlet-name>dispatcher</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<init-param>
<param-name>contextConfigLocation</param-name>
<param-value>/WEB-INF/classes/dispatcher.xml</param-value>
</init-param>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>dispatcher</servlet-name>
<url-pattern>*.html</url-pattern>
</servlet-mapping>

    <!-- 防止中文字符乱码 -->
    <filter>
        <filter-name>characterEncodingFilter</filter-name>
        <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
        <init-param>
            <param-name>encoding</param-name>
            <param-value>UTF-8</param-value>
        </init-param>
    </filter>
    <filter-mapping>
        <filter-name>characterEncodingFilter</filter-name>
        <url-pattern>/*</url-pattern>
    </filter-mapping>
 <!-- jsp页面需要引入的标签,存放在本地项目中,避免从网络下载 -->
<jsp-config>
<taglib>
<taglib-uri>http://java.sun.com/jsp/jstl/core</taglib-uri>
<taglib-location>/WEB-INF/tld/c.tld</taglib-location>
</taglib>
<taglib>
<taglib-uri>http://java.sun.com/jsp/jstl/fmt</taglib-uri>
<taglib-location>/WEB-INF/tld/fmt.tld</taglib-location>
</taglib>
<taglib>
<taglib-uri>http://java.sun.com/jsp/jstl/functions</taglib-uri>
<taglib-location>/WEB-INF/tld/fn.tld</taglib-location>
</taglib>
<taglib>
<taglib-uri>http://www.springframework.org/tags</taglib-uri>
<taglib-location>/WEB-INF/tld/spring.tld</taglib-location>
</taglib>
</jsp-config>
</web-app>

在web.xml中，我们新增了jsp-config的配置，这是将这些用到的标签放到了项目本地，目的是避免网络下载



在dispatcher.xml中，我们配置了视图的存放路径，所以需要新建这个路径文件

5.业务代码

UserController.java

@Controller
@RequestMapping("/user")
public class UserController {

@RequestMapping("/register")
public String register(){
return "user/register";
}

@RequestMapping(method=RequestMethod.POST)
public ModelAndView createUser(User user){
ModelAndView mv = new ModelAndView();
mv.setViewName("user/createSuccess");
mv.addObject("user", user);
return mv;

}
}

User.java

public class User {
private String userName;
private String password;
private String realName;
public String getUserName() {
return userName;
}
public void setUserName(String userName) {
this.userName = userName;
}
public String getPassword() {
return password;
}
public void setPassword(String password) {
this.password = password;
}
public String getRealName() {
return realName;
}
public void setRealName(String realName) {
this.realName = realName;
}

}

register.jsp

<%@ page language="java" contentType="text/html; charset=UTF-8"  pageEncoding="UTF-8"%>
<%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c"%>

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
<head>
<title>新增用户</title>
</head>

<body>

<form action="<c:url value="/user.html"/>" method="post">
<table>
<tr>
<td>用户名:</td>
<td><input type="text" name="userName"/></td>
</tr>
<tr>
<td>密码:</td>
<td><input type="password" name="password"/></td>
</tr>
<tr>
<td>姓名:</td>
<td><input type="text" name="realName"/></td>
</tr>
<tr>
<td colspan="2"><input type="submit" name="提交"/></td>
</tr>
</table>
</form>
</body>
</html>

createSuccess.jsp

<%@ page language="java" contentType="text/html; charset=UTF-8"  pageEncoding="UTF-8"%>
<%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c"%>

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
<head>
<title>创建用户成功</title>
</head>

<body>

恭喜！${user.userName}创建成功
</body>
</html>

这样一个完整的springmvc的demo工程新建完成。

然后部署到tomcat下，进行测试一下


http://localhost:8080/smvc/user/register.html中的smvc自己在转web项目的时候的命名，如果不知道，可以再tomcat的部署路径下查看
