SpringMVC视图解析器配置式开发

package cn.happy.day03MultiAction;

import org.springframework.web.servlet.ModelAndView;
import org.springframework.web.servlet.mvc.multiaction.MultiActionController;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;


//默认方法名解析器
public class MyMultiActionController extends MultiActionController {

    //自定义两个方法
    public String doFirst(HttpServletRequest request,HttpServletResponse response){
        return "doFirst";//访问jsp名称
    }

    public String doSecond(HttpServletRequest request,HttpServletResponse response){
        return "doSecond";
    }

}
