1.创建Dynamic web项目
2. 导入springmvc的jar包
3.编写TestController类
@Controller
public class HelloController {
@RequestMapping("hello")
public ModelAndView hello(){
System.out.println("hello springmvc....");
//创建ModelAndView对象
ModelAndView mav = new ModelAndView();
//设置模型数据
mav.addObject("msg", "hello springmvc...");
//设置视图名字
mav.setViewName("/WEB-INF/jsp/hello.jsp");
return mav;
}
}
4.创建hello.jsp页面
5.创建与配置springmvc.xml核心配置文件
6.在web.xml中配置前端控制器
<!-- 配置前端控制器 -->
<servlet>
<servlet-name>springmvc</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<!-- 加载springmvc核心配置文件 -->
<init-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:springmvc.xml</param-value>
</init-param>
</servlet>
<!-- 配置拦截路径 -->
<servlet-mapping>
<servlet-name>springmvc</servlet-name>
<url-pattern>*.action</url-pattern>
</servlet-mapping>
7. 启动项目通过浏览器测试
