使用Spring MVC编码问题 [英] Encoding problem using Spring MVC
问题描述
我有一个创建用户的演示Web应用程序.当我尝试以其他语言(例如法语)插入数据时，字符编码不正确.控制器上的代码为:
I have a demo web application that creates users. When I try to insert data in other languages (like french) the characters are not encoded correctly. The code on the controller is:
@SuppressWarnings("unchecked")
@RequestMapping(value = "/user/create.htm", params={"id"}, method = RequestMethod.GET)
public String edit(@RequestParam("id") Long id, ModelMap model) {
System.out.println("id is " + id);
User user = userService.get(id);
model.put("user", user);
return "user/create";
}
@RequestMapping(value = "/user/create.htm", method = RequestMethod.POST)
public String save(@ModelAttribute("user") User user, BindingResult result) {
System.out.println(user.getFirstName());
System.out.println(user.getLastName());
validator.validate(user, result);
if(result.hasErrors()) {
return "user/create";
}
userService.save(user);
return "redirect:list.htm";
}
我的web.xml是:
my web.xml is:
...
<filter>
<filter-name>encoding-filter</filter-name>
<filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
<init-param>
<param-name>encoding</param-name>
<param-value>UTF-8</param-value>
</init-param>
<init-param>
<param-name>forceEncoding</param-name>
<param-value>true</param-value>
</init-param>
</filter>
<filter-mapping>
<filter-name>encoding-filter</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
...
，页面为:
<%@ page language="java" contentType="text/html; charset=UTF-8"
pageEncoding="UTF-8"%>
<%@ taglib prefix="form" uri="http://www.springframework.org/tags/form" %>
<%@ taglib prefix="spring" uri="http://www.springframework.org/tags" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
...
<form:form method="post" commandName="user">
...
<form:input path="firstName" cssErrorClass="form-error-field"/>
...
当我在名字中输入一些法语字符时，system.out.println的输出为????+?????或类似的内容.
when I enter some french characters in the first name then the output from the system.out.println is ????+????? or something similar.
我看到其他人使用CharacterEncodingFilter修复了此问题，但这似乎不起作用.
I saw other people fixing this with the CharacterEncodingFilter but this doesn't seem to work.
非常感谢.
编辑过滤器值.
推荐答案
尝试使CharacterEncodingFilter成为web.xml中的第一个过滤器.
Try making CharacterEncodingFilter the first filter in web.xml.
我意识到这个问题有点老了，但是我遇到了同样的问题，移动CharacterEncodingFilter为我解决了这个问题.
I realize this question is a little old, but I just ran into the same problem, and moving CharacterEncodingFilter fixed it for me.
