1.今天在做一个例子的时候，发现后台不能正确接收中文的url参数，试了各种解决办法都不可以。

以下是代码：
Controller：

package com.springapp.mvc;
import org.springframework.stereotype.Controller;
import org.springframework.ui.ModelMap;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
@Controller
@RequestMapping("/")
public class HelloController {
    @RequestMapping(method = RequestMethod.GET)
    public String printWelcome(ModelMap model) {
        model.addAttribute("message", "Hello world IDEA!");
        model.put("content","This is my first springmvc web");
        return "index";
    }
    @RequestMapping(value = "/page/{name}/{age}",method = RequestMethod.GET)
    public String getName(ModelMap modelMap, @PathVariable("name") String name, @PathVariable("age") int age) {
        modelMap.addAttribute("name",name);
        modelMap.addAttribute("age",age);
        return "name";
    }
}

name.jsp

<%@ page pageEncoding="UTF-8" language="java" %>


    


    

        名字：${name}

        年龄:${age}
