1、SpringMVC-基础入门

一、导入SpringMVC

<dependency>
    <groupId>org.springframework</groupId>
    <artifactId>spring-webmvc</artifactId>
    <version>${sping-version}</version>
</dependency>

二、在web.xml配置

<servlet>
    <servlet-name>springmvc</servlet-name>
    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
    <init-param>
          <param-name>contextConfigLocation</param-name>
            <!--  加载配置文件 -->
          <param-value>classpath:spring-mvc.xml</param-value>
      </init-param>
      <!-- <load-on-startup>1</load-on-startup> -->
</servlet>
<servlet-mapping>
    <servlet-name>springmvc</servlet-name>
    <url-pattern>/</url-pattern>
</servlet-mapping>

三、在resources中创建spring-mvc.xml

<!--扫描-->
<!--如果spring已经有扫描所有的包，下面这句可以省略-->
<context:component-scan base-package="com.werner.controller"/>
<!--不要处理静态资源-->
<mvc:default-servlet-handler/>
<!-- 开启spring注解 -->
<mvc:annotation-driven/>
<!-- 配置视图解析器 -->
<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver"
      id="internalResourceViewResolver">
  <!-- 前缀 -->
  <property name="prefix" value="/WEB-INF/jsp/" />
  <!-- 后缀 -->
  <property name="suffix" value=".jsp" />
</bean>

四、创建Controller

@Controller
public class HelloController {
    @RequestMapping("/hello")
    public String hello(){
        return "hello";
    }
}

五、启动tomcat访问
