SpringMVC快速入门 需求：客户端发起请求，服务器端接收请求，执行逻辑并进行视图跳转。 开发步骤 ①导入SpringMVC相关坐标 ②配置SpringMVC核心控制器DispathcerServlet ③创建Controller类和视图页面 ④使用注解配置Controller类中业务方法的映射地址 ⑤配置SpringMVC核心文件 spring-mvc.xml ⑥客户端发起请求测试 代码实现 ①导入Spring和SpringMVC的坐标、导入Servlet和Jsp的坐标 <!--Spring坐标-->
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-context</artifactId>
<version>5.0.5.RELEASE</version>
</dependency>
<!--SpringMVC坐标-->
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-webmvc</artifactId>
<version>5.0.5.RELEASE</version>
</dependency>
<!--Servlet坐标-->
<dependency>
<groupId>javax.servlet</groupId>
<artifactId>servlet-api</artifactId>
<version>2.5</version>
</dependency>
<!--Jsp坐标-->
<dependency>
<groupId>javax.servlet.jsp</groupId>
<artifactId>jsp-api</artifactId>
<version>2.0</version>
</dependency>②在web.xml配置SpringMVC的核心控制器 <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:spring-mvc.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>
③创建Controller和业务方法 public class QuickController {
public String quickMethod(){
System.out.println("quickMethod running.....");
return "index";
}
}③创建视图页面index.jsp <html>
<body>
<h2>Hello SpringMVC!</h2>
</body>
</html>④配置注解 @Controller
public class QuickController {
@RequestMapping("/quick")
public String quickMethod(){
System.out.println("quickMethod running.....");
return "index";
}
}⑤创建spring-mvc.xml <beans xmlns="http://www.springframework.org/schema/beans"
xmlns:mvc="http://www.springframework.org/schema/mvc"
xmlns:context="http://www.springframework.org/schema/context"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans.xsd
http://www.springframework.org/schema/mvc
http://www.springframework.org/schema/mvc/spring-mvc.xsd
http://www.springframework.org/schema/context
http://www.springframework.org/schema/context/spring-context.xsd">
<!--配置注解扫描-->
<context:component-scan base-package="com.itheima"/>
</beans>⑥访问测试地址 http://localhost:8080/itheima_springmvc1/quick 控制台打印 file://D:/%E5%AD%A6%E4%B9%A0%E7%94%A8/(05)springmvc-day01/01-springmvc%E5%BF%AB%E9%80%9F%E5%85%A5%E9%97%A8%E3%80%81%E7%BB%84%E4%BB%B6%E8%A7%A3%E6%9E%90/%E7%AC%94%E8%AE%B0/img/%E5%9B%BE%E7%89%871.png?lastModify=1562465186
