2 配置核心的控制器（配置DispatcherServlet）
2.1 在web.xml配置文件中核心控制器DispatcherServlet
<web-app>
<display-name>Archetype Created Web Application</display-name>
<!--配置前端控制器-->
<servlet>
<servlet-name>dispatcherServlet</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<init-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:springmvc.xml</param-value>
</init-param>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>dispatcherServlet</servlet-name>
<url-pattern>/</url-pattern>
</servlet-mapping>
<!--配置解决中文乱码的过滤器-->
<filter>
<filter-name>characterEncodingFilter</filter-name>
<filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
<init-param>
<param-name>encoding</param-name>
<param-value>UTF-8</param-value>
</init-param>
</filter>
<filter-mapping>
<filter-name>characterEncodingFilter</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
</web-app>
2.2 编写springmvc.xml的配置文件
<!-- 开启注解扫描 -->
<context:component-scan base-package="cn.edu.nuaa"/>
<!-- 开启SpringMVC框架注解的支持 -->
<mvc:annotation-driven conversion-service="conversionService"/>
<!--配置自定义类型转换器-->
<bean id="conversionService" class="org.springframework.context.support.ConversionServiceFactoryBean">
<property name="converters">
<set>
<bean class="cn.edu.nuaa.utils.StringToDateConverter"/>
</set>
</property>
</bean>
<!-- 视图解析器对象 -->
<bean id="internalResourceViewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<property name="prefix" value="/WEB-INF/pages/"/>
<property name="suffix" value=".jsp"/>
</bean>
4 编写index.jsp和HelloController控制器类
4.1 index.jsp
<%@ page contentType="text/html;charset=UTF-8" language="java" %>
<html>
<head>
<title>入门程序</title>
</head>
<body>
<h1>入门程序</h1>
</body>
</html>
4.2 HelloController
package cn.edu.nuaa.controller;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
// 控制器类
@Controller
@RequestMapping(path="/user")
public class HelloController {
/**
* 入门案例
* @return
*/
@RequestMapping(path="/hello")
public String sayHello(){
System.out.println("Hello StringMVC");
return "success";
}
/**
* RequestMapping注解
* @return
*/
@RequestMapping(value="/testRequestMapping",params = {"username=heihei"},headers = {"Accept"})
public String testRequestMapping(){
System.out.println("测试RequestMapping注解...");
return "success";
}
}
