spring mvc环境搭建 spring mvc项目搭建

因在Spring官网上都推荐使用Maven下载相关的Spring jar包，故复习了一下如何使用Maven构建Spring MVC，顺便学习一下Spring MVC。（m2eclipse的插件的安装，在此不作描述。）

一、新建Maven工程，如下图所示

1、右键新建项目

2、可以在搜索中直接输入maven

3、我这里选择的是使用默认的项目空间

4、选择Maven webapp

5、输入相应的项目名称

注：关于Group Id等字段的意义可参考该文章：http://www.iteye.com/topic/973166

6点击Finish

二、添加Dynamic Web Module

1、点击工程，使用组合键：alt + enter

2、选择Project Facets

3、增加目录：src/test/resources

4、复制WebContent/WEB-INF/下的web.xml到 /webmvct/src/main/webapp/WEB-INF目中

5、删除WebContent文件

6、点击工程使用组合键，打开工程选项，删除以下几项：

7、增加目录：webapp 和 Maven Dependenices

三、修改 web.xml文件

[html]  view plain  copy

 

1. <?xml version="1.0" encoding="UTF-8"?>  
2. <web-app id="WebApp_ID" version="2.4"  
3. xmlns="http://java.sun.com/xml/ns/j2ee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"  
4. xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd">  
5. <display-name>webmvct</display-name>  
6. <context-param>  
7. <param-name>webAppRootKey</param-name>  
8. <param-value>webmvct.root</param-value>  
9. </context-param>  
10.   
11.       
12. <context-param>  
13. <param-name>log4jConfigLocation</param-name>  
14. <param-value>WEB-INF/log4j.properties</param-value>  
15. </context-param>  
16.       
17. <listener>  
18. <listener-class>org.springframework.web.util.Log4jConfigListener</listener-class>  
19. </listener>  
20.       
21. <listener>  
22. <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>  
23. </listener>  
24.   
25. <servlet>  
26. <servlet-name>webmvct</servlet-name>  
27. <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>  
28. <load-on-startup>1</load-on-startup>  
29. </servlet>  
30. <servlet-mapping>  
31. <servlet-name>webmvct</servlet-name>  
32. <url-pattern>/</url-pattern>  
33. </servlet-mapping>  
34. <welcome-file-list>  
35. <welcome-file>index.jsp</welcome-file>  
36. </welcome-file-list>  
37. </web-app>  
38.

四、在WEB-INF 目录下增加文件： 工程名-servlet.xml

(WEB-INF/webmvct-servlet.xml)

[html]  view plain  copy

 

1. <?xml version="1.0" encoding="UTF-8"?>  
2. <beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"  
3. xmlns:p="http://www.springframework.org/schema/p" xmlns:context="http://www.springframework.org/schema/context"  
4. xmlns:jee="http://www.springframework.org/schema/jee" xmlns:tx="http://www.springframework.org/schema/tx"  
5. xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.5.xsd  
6.                 http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-2.5.xsd  
7.                 http://www.springframework.org/schema/jee http://www.springframework.org/schema/jee/spring-jee-2.5.xsd  
8. >  
9.   
10. <!-- 对包中的所有类进行扫描，以完成Bean创建和自动依赖注入的功能 稍后会创建该包：webmvct.cmd -->      
11. <context:component-scan base-package="webmvct.cmd"/>  
12.   
13.       
14. <!-- 定义Spring MVC 的模板文件 -->  
15. <bean id="viewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver">  
16. <property name="viewClass" value="org.springframework.web.servlet.view.JstlView"/>     <!-- 支持JSTL -->  
17. <property name="prefix" value="/WEB-INF/jsp/" />              <!-- 模板的路径 -->  
18. <property name="suffix" value=".jsp" />                <!-- 模板文件的后缀-->  
19. </bean>  
20.       
21. <

五、修改pom.xml

可到该网址查询相应的spring包：http://repo.spring.io/webapp/browserepo.html?0

[html]  view plain  copy

 

1. <project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"  
2. xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd">  
3. <modelVersion>4.0.0</modelVersion>  
4. <groupId>com.learn.cm</groupId>  
5. <artifactId>webmvct</artifactId>  
6. <packaging>war</packaging>  
7. <version>0.0.1-SNAPSHOT</version>  
8. <name>webmvct Maven Webapp</name>  
9. <url>http://maven.apache.org</url>  
10. <dependencies>  
11. <dependency>  
12. <groupId>junit</groupId>  
13. <artifactId>junit</artifactId>  
14. <version>3.8.1</version>  
15. <scope>test</scope>  
16. </dependency>  
17. <dependency>  
18. <groupId>org.springframework</groupId>  
19. <artifactId>spring</artifactId>

25. <version>2.5.6</version>  
26. </dependency>  
27. <dependency>  
28. <groupId>org.mortbay.jetty</groupId>  
29. <artifactId>servlet-api-2.5</artifactId>  
30. <version>6.0.1</version>  
31. </dependency>  
32. <dependency>  
33. <groupId>javax.servlet</groupId>  
34. <artifactId>jstl</artifactId>  
35. <version>1.1.2</version>  
36. </dependency>  
37.   
38. <dependency>  
39. <groupId>log4j</groupId>  
40. <artifactId>log4j</artifactId>  
41. <version>1.2.14</version>  
42. </dependency>  
43. </dependencies>  
44. <build>  
45. <finalName>webmvct</finalName>  
46. </build>  
47. </project>

六、在src/main/java 文件夹中新建类 WebMVCTController

七、在WEB-INF目录下新建文件夹jsp ，并在jsp文件夹中新建login.jsp

[html]  view plain  copy

 
    
 
1. <!DOCTYPE html>  
2. <html>  
3. <head>  
4. <title>webmvct简单例子</title>  
5. <meta charset="utf-8">      
6. <meta name="viewport" content="width=device-width, initial-scale=1.0">  
7. <!-- Bootstrap -->  
8. <link rel="stylesheet" href="http://cdn.bootcss.com/twitter-bootstrap/3.0.3/css/bootstrap.min.css">  
9. <link rel="stylesheet" href="http://v3.bootcss.com/examples/signin/signin.css"/>  
10. <!-- HTML5 Shim and Respond.js IE8 support of HTML5 elements and media queries -->  
11. <!-- WARNING: Respond.js doesn't work if you view the page via file:// -->  
12. >  
13. <script src="http://cdn.bootcss.com/html5shiv/3.7.0/html5shiv.min.js"></script>  
14. <script src="http://cdn.bootcss.com/respond.js/1.3.0/respond.min.js"></script>  
15. >  
16. <!-- jQuery (necessary for Bootstrap's JavaScript plugins) -->  
17. <script src="http://cdn.bootcss.com/jquery/1.10.2/jquery.min.js"></script>  
18. <!-- Include all compiled plugins (below), or include individual files as needed -->  
19. <script src="http://cdn.bootcss.com/twitter-bootstrap/3.0.3/js/bootstrap.min.js"></script>   
20. </head>  
21. <body>  
22. <div  class="container">  
23. <form class="form-signin" role="form" action="login">  
24. <h2 class="form-signin-heading">登陆</h2>  
25. <input type="text" name="username" class="form-control" placeholder="请输入用户名" required autofocus>  
26.     
27. <button class="btn btn-lg btn-primary btn-block" type="submit">登陆</button>  
28. </form>  
29.      
30. </body>  
31. </html>

八、同时新建文件：business.jsp

[html]  view plain  copy

 
    
 
1. <!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">  
2. <html>  
3. <head>  
4. <meta http-equiv="Content-Type" content="text/html; charset=utf-8">  
5. <title>欢迎</title>  
6. </head>  
7. <body>  
8.     ${userName}  
9. </body>  
10. </html>

九、在WEB-INF目录下创建log4j配置文件：

log4j.properties

[java]  view plain  copy

 

1. # For JBoss: Avoid to setup Log4J outside $JBOSS_HOME/server/default/deploy/log4j.xml!  
2. # For all other servers: Comment out the Log4J listener in web.xml to activate Log4J.  
3. log4j.rootLogger=DEBUG, stdout  
4.   
5. log4j.appender.stdout=org.apache.log4j.ConsoleAppender  
6. log4j.appender.stdout.layout=org.apache.log4j.PatternLayout  
7. log4j.appender.stdout.layout.ConversionPattern=%d %p [%c] - %m%n

十、在WEB-INF文件夹中增加文件applicationContext.xml

[html]  view plain  copy

 

1. <?xml version="1.0" encoding="UTF-8"?>  
2.   
3. <beans xmlns="http://www.springframework.org/schema/beans"  
4. xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"  
5. xmlns:aop="http://www.springframework.org/schema/aop"  
6. xmlns:tx="http://www.springframework.org/schema/tx"  
7. xmlns:context="http://www.springframework.org/schema/context"  
8. xsi:schemaLocation="http://www.springframework.org/schema/beans   
9.            http://www.springframework.org/schema/beans/spring-beans-2.5.xsd  
10.            http://www.springframework.org/schema/aop   
11.            http://www.springframework.org/schema/aop/spring-aop-2.5.xsd  
12.            http://www.springframework.org/schema/tx   
13.            http://www.springframework.org/schema/tx/spring-tx-2.5.xsd  
14.            http://www.springframework.org/schema/context   
15.            http://www.springframework.org/schema/context/spring-context-2.5.xsd    
16. >  
17.   
18. <!-- the parent application context definition for the springapp application -->  
19.   
20. <!--     <bean class="org.springframework.beans.factory.annotation.AutowiredAnnotationBeanPostProcessor"/>  
21.  -->  
22. </beans>

十一、修改index.jsp文件

[html]  view plain  copy

 

1. <%  
2.    request.getRequestDispatcher("/WEB-INF/jsp/login.jsp").forward(request,response);  
3. >

十二、发布，启动工程

在浏览器中输入：http://localhost:8080/webmvct/
