创建springMvc项目

引入jar包：

引入springmvc的jar包；

必须引入的jar包

1. commons-logging.jar
2. spring-aop.jar
3. spring-beams.jar
4. spring-context.jar
5. sprign-core.jar
6. spring-expression.jar
7. spring-web.jar
8. spring-webmvc.jar

在web.xml中配置dispatcherServlet

<!--开始·配置dispatcherServlet-->
    <servlet>
        <servlet-name>dispatcher</servlet-name>
        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
        <!--配置dispatcherServlet初始化参数;用来配置springmvc配置文件的名称和位置-->
        <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>dispatcher</servlet-name>
        <url-pattern>/</url-pattern>
    </servlet-mapping>

加入springMVC的配置文件

//声明控制器作用的包路径
<context:component-scan base-package="com.spring.mvc"></context:component-scan>
    <!--视图解析器:将逻辑视图转为物理视图-->
    <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        <property name="prefix" value="/"></property>
        <property name="suffix" value=".jsp"></property>
    </bean>

编写处理请求的处理器，并标注为处理器

package com.laishuai.springmvc.text;

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;

@Controller
public class HelloWord {
    @RequestMapping("/hello")
    public String sayHelloWord() {
        System.out.println("helloWord");
        return "success";
    }
}

编写视图

//href的值为需要需要请求的mapping对象值
<a href="hello">hello</a>
