创建第一个简单springmvc步骤。
(一)首先配置好jdk、tomcat。
(二)导入jar包
(三)添加配置文件:springmvc.xml
<?xmlversion="1.0"encoding="UTF-8"?>
<beansxmlns="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/beanshttp://www.springframework.org/schema/beans/spring-beans.xsd
http://www.springframework.org/schema/contexthttp://www.springframework.org/schema/context/spring-context-4.0.xsd
http://www.springframework.org/schema/mvchttp://www.springframework.org/schema/mvc/spring-mvc-4.0.xsd">
<!-- 配置自定扫描的包 -->
<context:component-scanbase-package="com.atguigu.springmvc"></context:component-scan>
<!-- 配置视图解析器: 如何把 handler方法返回值解析为实际的物理视图 -->
<beanclass="org.springframework.web.servlet.view.InternalResourceViewResolver">
<propertyname="prefix"value="/WEB-INF/views/"></property>
<propertyname="suffix"value=".jsp"></property>
</bean>
<!-- 配置视图 BeanNameViewResolver解析器:使用视图的名字来解析视图 -->
<!-- 通过 order 属性来定义视图解析器的优先级, order值越小优先级越高 -->
<beanclass="org.springframework.web.servlet.view.BeanNameViewResolver">
<propertyname="order"value="100"></property>
</bean>
<!-- 配置国际化资源文件 -->
<beanid="messageSource"
class="org.springframework.context.support.ResourceBundleMessageSource">
<propertyname="basename"value="i18n"></property>
</bean>
<!-- 配置直接转发的页面 -->
<!-- 可以直接相应转发的页面, 而无需再经过 Handler 的方法. -->
<mvc:view-controllerpath="/success"view-name="success"/>
<!-- 在实际开发中通常都需配置 mvc:annotation-driven标签 -->
<mvc:annotation-driven></mvc:annotation-driven>
</beans>
(四)配置web文档
<?xmlversion="1.0"encoding="UTF-8"?>
<web-appxmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"xmlns="http://java.sun.com/xml/ns/javaee"xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"xsi:schemaLocation="http://java.sun.com/xml/ns/javaeehttp://java.sun.com/xml/ns/javaee/web-app_3_0.xsd"id="WebApp_ID"version="3.0">

<!-- 配置 org.springframework.web.filter.HiddenHttpMethodFilter:可以把 POST请求转为 DELETE或 POST 请求 -->
<filter>
