springmvc-servlet.xml(名字可随取)

controller类：

package com.dw.controller;
    
    import javax.annotation.Resource;
    
    import org.springframework.stereotype.Controller;
    import org.springframework.web.bind.annotation.RequestMapping;
    import org.springframework.web.servlet.ModelAndView;
    
    import com.dw.service.PersonService;
    
    @Controller
    public class PersonController {
    	@Resource
    	private PersonService personService;
        
    	@RequestMapping("/toAdd.do")
    	public ModelAndView toAdd(){
    		ModelAndView modelAndView = new ModelAndView();
    		modelAndView.setViewName("/WEB-INF/pages/toAdd.jsp");		
    		return modelAndView;
    	}
    }

在地址栏里输入……/toAdd.do之后，经核心转发器DispatherServlet处理后将转至toAdd.jsp页面。

视图解析器配置前后缀：  
在springmvc-servlet.xml中添加配置：

修改controller中的返回视图：modelAndView.setViewName("toAdd");
