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" %>
<html>
<head>
<title></title>
</head>
<body>
<p>
名字：${name}<br/>
年龄:${age}<br/>
</p>
</body>
</html>
web.xml

大部分解決方式樓上都已經講得比較清楚了。我把3種方式整理一下吧
Tomcat 可以直接設定
URIEconding="UTF-8"new String("中文".getBytes("ISO-8859-1"), "UTF-8");將中文使用
URLEncoder編碼如：baidu.com/s?wd=%E4%BD%A0%E5%A5%BD%E4%B8%96%E7%95%8C這3種方式都可以解決中文URL亂碼問題。
get提交用 string類別的建構方法
有沒有debug下看後台接收到的資料是亂碼？還是到資料庫亂碼了？兩者是不同的情況，前者可以嘗試
request.setCharacterEncoding方法，并且用new String(para.getBytes(“ISO-8859-1”),“UTF-8”對參數進行轉碼試試，如果看到後台的不是亂碼，到數據庫亂碼那就看數據庫鏈接上是不是忘了加enConding…我的做法是
springmvc中文亂碼問題:http://luanxiyuan.iteye.com/blog/1849169
new String(接收的參數.getBytes("ISO-8859-1"), "UTF-8");
容器的字符集指定了嗎
如果是 tomcat 容器的話,請配置
URIEconding="UTF-8" useBodyEncodingForURI="true"可以在前端用Base64編碼後傳到後台解碼
@RequestMapping(value = "/xxx", method = RequestMethod.GET, headers = {"content-type=application/json;charset=UTF-8"}, Produces = {"application/json;charset=UTF-8 “}）
