用idea+tomcat学习SpringMVC,尝试入门工程的时候tomcat启动成功,应用部署成功
,从tomcat日志看,映射也成功了,但是从浏览器访问报404错误,请各位指点.
web.xml没改
<?xml version="1.0" encoding="UTF-8"?>

dispacher-servlet.xml加了一行
<?xml version="1.0" encoding="UTF-8"?>

<context:component-scan base-package="controller" />

controller是这样的
package controller;
import com.sun.deploy.net.HttpResponse;
import org.springframework.http.HttpRequest;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.servlet.ModelAndView;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
@Controller
public class controller {
@RequestMapping("/1")
public ModelAndView controller(HttpServletRequest request, HttpServletResponse response){
ModelAndView mav = new ModelAndView();
mav.addObject("msg","a springMVCDemo");
mav.setViewName("/1.jsp");
return mav;
}
}

http://localhost:8080/1.jsp能正常访问jsp
