本例子为你讲解在spring3中如何使用基于注解的mvc框架.

例子中使用到的工具:
MyEclipse 9.1
jdk 1.6

1.添加Jar包引用
由于使用了Maven管理项目,所以,第一步就是添加引用.(没有使用Maven怎么办?那你直接下载Spring3的压缩包,添加相应的Jar文件就可以了。)

Java代码

<dependency>

<groupId>org.springframework</groupId>

<artifactId>spring-web</artifactId>

<version>3.1.1.RELEASE</version>

<type>jar</type>

<scope>compile</scope>

</dependency>

<dependency>

<groupId>org.springframework</groupId>

<artifactId>spring-core</artifactId>

<version>3.1.1.RELEASE</version>

<type>jar</type>

<scope>compile</scope>

</dependency>

<dependency>

<groupId>org.springframework</groupId>

<artifactId>spring-webmvc</artifactId>

<version>3.1.1.RELEASE</version>

<type>jar</type>

<scope>compile</scope>

</dependency>



2.编写 Controller 和 Mapping
我们采用注解的方式配置,如果想使用XML的方式,可以查看文档,都是一样的配制方法.

Java代码

packagecom.vito.action;

importorg.springframework.stereotype.Controller;

importorg.springframework.ui.ModelMap;

importorg.springframework.web.bind.annotation.RequestMapping;

importorg.springframework.web.bind.annotation.RequestMethod;

@Controller

@RequestMapping("/welcome")

publicclassHelloWorldController{

@RequestMapping(value="/hello",method=RequestMethod.GET)

publicStringprintWelcome(ModelMapmodel){

model.addAttribute("message","Spring3MVCHelloWorld");

return"hello";

}

}


3.JSP视图

Java代码

<html>

<body>

<h2>Message:${message}</h2>

</body>

</html>


4.Spring配置文件

Java代码

<beansxmlns="http://www.springframework.org/schema/beans"

xmlns:context="http://www.springframework.org/schema/context"

xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

xsi:schemaLocation="

http://www.springframework.org/schema/beans

http://www.springframework.org/schema/beans/spring-beans-3.0.xsd

http://www.springframework.org/schema/context

http://www.springframework.org/schema/context/spring-context-3.0.xsd">

<context:component-scanbase-package="com.vito.action"/>

<bean

class="org.springframework.web.servlet.view.InternalResourceViewResolver">

<propertyname="prefix">

<!--这个配置是配置JSP页面的位置,按照你自己的配置来配-->

<value>/WEB-INF/pages/</value>

</property>

<propertyname="suffix">

<value>.jsp</value>

</property>

</bean>

</beans>


5.web.xml

Java代码

<?xmlversion="1.0"encoding="UTF-8"?>

<web-appversion="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">

<servlet>

<servlet-name>springMvc</servlet-name>

<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>

<init-param>

<param-name>contextConfigLocation</param-name>

<param-value>classpath:applicationContext.xml</param-value>

</init-param>

</servlet>

<servlet-mapping>

<servlet-name>springMvc</servlet-name>

<url-pattern>/</url-pattern>

</servlet-mapping>

</web-app>
