SpringMVC快速入门

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

导入Spring和SpringMVC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>

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>   //spring=mvc的配置文件
</init-param>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>DispatcherServlet</servlet-name>
<url-pattern>/</url-pattern>
</servlet-mapping>  //默认会拦截html和jsp的请求需要加上下面的mapping
 <servlet-mapping>
  <servlet-name>default</servlet-name>
  <url-pattern>*.html</url-pattern>
  </servlet-mapping>

3创建Controller和业务方法#

@Controller  //Spring Servlet的新注解
public class QuickController {
@RequestMapping("/quick")
public String quickMethod(){
System.out.println(" running.....");
return "index.html";  //功能上相当于转发
}}

4创建spring-mvc.xml#
