@PathVariable

@PathVariable和RequestParam差不多

package com.exa.de.controller;

import org.springframework.boot.jdbc.metadata.HikariDataSourcePoolMetadata;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.PatchMapping;
import org.springframework.web.bind.annotation.PathVariable;

import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.web.servlet.ModelAndView;

@Controller
public class ParamsController {
    public static final  String PAGE="param";
/*ModelAndView=Model+View>>>Model=模型;View=视图;
设置转向地址
将底层获取的数据进行存储（或者封装）
最后将数据传递给View
Model是每一次请求可以自动创建，但是ModelAndView 是需要我们自己去new的-
 */

    @RequestMapping("/path/{id}/{type}")
    public ModelAndView path(@PathVariable(required = false)int id,   //http://localhost:8080/path/07/霖
                             @PathVariable(required = false)String type){

    //required = false传值给后台

    System.out.println("id="+id);
    System.out.println("type+"+type);
    ModelAndView view =new ModelAndView(PAGE);
    view.addObject("id",id);
    view.addObject("type",type);
    return view;
    }
}
