springmvc项目开发步骤详解

springmvc项目开发步骤:

第一步:导入包

1.spring-framework-3.2.8.RELEASE-dist\spring-framework-3.2.8.RELEASE\libs

2.jstl.jar

3.standard.jar

4.commons-logging-1.1.1.jar

5.commons-logging-api-1.1.jar

第二步:在web.xml配置springmvc的核心DispatcherServlet

<servlet>

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

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

        <init-param>

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

                <param-value>/WEB-INF/applicationContext*.xml</param-value>

        </init-param>

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

</servlet>

注意加载指定配置文件

第三步:写springmvc须要加载的配置文件

applicationContext-servlet.xml配置:

<!--指定组件扫描-->

<context:component-scan base-package="org.fkjava.springmvc.controller"/>

<!--开启annotation注解-->

<mvc:annotation-driven />

<!--配置JSP视图解析器-->

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

        <property name="viewClass" value="org.springframework.web.servlet.view.JstlView"/>

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

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

</bean>

 第四步:写spring须要加载的配置文件

applicationContext.xml

第五步:编写控制层Controller类

@Controller注解控制器类

@RequestMapping 注解请求地址映射

@RequestParam注解请求参数
