1.首先我們需要新建一個webapp項目,在pom.xml中引入相關依賴:
<!-- junit測試包 -->
<dependency>
<groupId>junit</groupId>
<artifactId>junit</artifactId>
<version>4.12</version>
<scope>test</scope>
</dependency>
<!-- spring基礎包 -->
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-context</artifactId>
<version>4.1.6.RELEASE</version>
</dependency>
<!-- springMVC的包 -->
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-webmvc</artifactId>
<version>4.1.6.RELEASE</version>
</dependency>
2.在web.xml中配置DispatcherServlet:
<!-- 配置springmvc的DispatcherServlet處理類 -->
<servlet>
<servlet-name>mvc-dispatcher</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>
<!-- 配置springmvc的DispatcherServlet映射處理URL -->
<servlet-mapping>
<servlet-name>mvc-dispatcher</servlet-name>
<url-pattern>/</url-pattern>
</servlet-mapping>
3.引入springmvc.xml文件,文件名字隨意,但是要與上面web.xml中配置的classpath名字相同
<?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:p="http://www.springframework.org/schema/p"
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-3.0.xsd
http://www.springframework.org/schema/context
http://www.springframework.org/schema/context/spring-context-3.0.xsd
http://www.springframework.org/schema/mvc
http://www.springframework.org/schema/mvc/spring-mvc-3.0.xsd">
<!-- 自己掃描bean -->
<context:component-scan base-package="com.yc" />
<!-- jsp頁面解析器,當Controller返回XXX字符串時,先通過攔截器,然後該類就會在/views/目錄下,查找XXX.jsp文件 -->
<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<property name="prefix" value="/views/" />
<property name="suffix" value=".jsp" />
</bean>
</beans>
4.發出請求
<a href="mvc/hello">Hello</a>
5.編寫請求處理類Controller
package com.yc.controllers;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
@Controller //標識爲請求處理類
@RequestMapping("/mvc") //攔截/mvc的請求
public class HelloController {
@RequestMapping("/hello") //攔截/hello的請求
public String hello(){
return "show"; //跳轉到show.jsp頁面
}
}
6.運行結果
