springmvc demo小结

一、SpringMVC基础入门，创建一个HelloWorld程序

1.首先，导入SpringMVC需要的jar包。

2、添加Web.xml配置文件中关于SpringMVC的配置

<!--configure the setting of springmvcDispatcherServlet and configure the mapping-->

<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:springmvc-servlet.xml</param-value>

      </init-param>

      <!-- <load-on-startup>1</load-on-startup> -->

</servlet>

<servlet-mapping>

    <servlet-name>springmvc</servlet-name>

    <url-pattern>/</url-pattern>

</servlet-mapping>

3.在src下添加springmvc-servlet.xml配置文件

<?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:context="http://www.springframework.org/schema/context"

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

    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-4.1.xsd

        http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-4.1.xsd">                   

    <!-- scan the package and the sub package -->

    <context:component-scan base-package="test.SpringMVC"/>

    <!-- don‘t handle the static resource -->

    <mvc:default-servlet-handler />

    <!-- if you use annotation you must configure following setting -->

    <mvc:annotation-driven />

    <!-- configure the InternalResourceViewResolver -->

    <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver"

            id="internalResourceViewResolver">

        <!-- 前缀 -->

        <property name="prefix" value="/WEB-INF/jsp/" />

        <!-- 后缀 -->

        <property name="suffix" value=".jsp" />

    </bean>

</beans>

4.在WEB-INF文件夹下创建名为jsp的文件夹，用来存放jsp视图。创建一个hello.jsp，在body中添加“Hello World”。

5.建立包及Controller，如下所示

6.编写Controller代码

@Controller

@RequestMapping("/mvc")

public class mvcController {

    @RequestMapping("/hello")

    public String hello(){       

        return "hello";

    }

}

7.启动服务器，键入 http://localhost:8080/项目名/mvc/hello

8、代码百度云链接 http://pan.baidu.com/s/1c1DMOI

注：

1>创建源文件需要用 source folder

2>设置out put路径为webContent/web-inf/classes
