SpringMVC01-->SpringMVC框架环境搭建(注解方式)

1.导入jar包

2.在web.xml中配置前端控制器DispatcherServlet

　　2.1 如果不配置<init-param>，则默认找/WEB-INF/<servlet-name>-servlet.xml.配置<init-param>是为了改变默认加载的配置文件名称和路径

<?xml version="1.0" encoding="UTF-8"?>
<web-app version="3.0" xmlns="http://java.sun.com/xml/ns/javaee"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://java.sun.com/xml/ns/javaee
    http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd">
    <!-- 配置前端控制器 -->
    <servlet>
        <servlet-name>jqk</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>jqk</servlet-name>
        <url-pattern>/</url-pattern>
    </servlet-mapping>
</web-app>

3.在src下新建springmvc.xml

　　3.1 引入xmlns:mvc命名空间（可以在spring帮助文档的/spring-framework-4.1.6.RELEASE-dist/spring-framework-4.1.6.RELEASE/docs/spring-framework-reference/htmlsingle中搜索）

<?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:mvc="http://www.springframework.org/schema/mvc"
xmlns:context="http://www.springframework.org/schema/context"
xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans.xsd
http://www.springframework.org/schema/context
http://www.springframework.org/schema/context/spring-context.xsd
http://www.springframework.org/schema/mvc
http://www.springframework.org/schema/mvc/spring-mvc.xsd">
<!-- 扫描注解 -->
<context:component-scan
base-package="com.bjsxt.controller"></context:component-scan>
<!-- 注解驱动 -->
<!--
org.springframework.web.servlet.mvc.annotation.DefaultAnnotationHandler
Mapping -->
<!--
org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerA
dapter -->
<mvc:annotation-driven></mvc:annotation-driven>
<!-- 静态资源 -->
<mvc:resources location="/js/" mapping="/js/**"></mvc:resources>
<mvc:resources location="/css/" mapping="/css/**"></mvc:resources>
<mvc:resources location="/images/"
mapping="/images/**"></mvc:resources>
</beans>

4.编写控制器类

@Controller
public class DemoController {
@RequestMapping("demo")
public String demo(){
System.out.println("执行 demo");
return "main.jsp";
}
@RequestMapping("demo2")
public String demo2(){
System.out.println("demo2");
return "main1.jsp";
}
}
