Question

我在mysql中将数据存储为¥à¤¨à¥à¤à¤°à¤¨¥。它在localhost中工作正常，但在远程mysql（在plesk中）它无法正常工作。我使用了以下内容：

 request.setCharacterEncoding("UTF-8");
response.setCharacterEncoding("UTF-8");

在servlet和

中

con=DriverManager.getConnection("jdbc:mysql://localhost:3306/projectkkm?useUnicode=yes&characterEncoding=UTF-8","root","");

数据库连接中的

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

在jsp中

根据我的研究，我发现问题出在Java中。 java for linux不支持hindi文本，请参阅url：http://www.oracle.com/technetwork/java/javase/javase7locales-334809.html

see this snapshot from oracle

在我的localhost（Windows）中它的工作正常但是当我将它部署到centos（linux）平台时它无法正常工作。我认为问题可能出在window / linux兼容性上。

任何人都可以帮我解决这个问题。我确信问题不是来自mysql方面。

Answer 1

尝试添加，

<filter>
    <filter-name>setCharacterEncodingFilter</filter-name>
    <filter-class>org.apache.catalina.filters.SetCharacterEncodingFilter</filter-class>
    <init-param>
        <param-name>encoding</param-name>
        <param-value>UTF-8</param-value>
    </init-param>
</filter>
<filter-mapping>
    <filter-name>setCharacterEncodingFilter</filter-name>
    <url-pattern>/*</url-pattern>
</filter-mapping>

web.xml中的

好像您的远程数据库配置不正确。

SHOW VARIABLES LIKE 'char%';

应该显示

character_set_client      utf8                     
character_set_connection   utf8               
character_set_database      utf8                
character_set_filesystem  binary                    
character_set_results        utf8                        
character_set_server         utf8                        
character_set_system       utf8

如果没有，你应该修复你/etc/mysql/my.cnf

在[mysqld]部分

中添加以下配置

character-set-server = utf8
init-connect='SET NAMES utf8'
collation-server=utf8_general_ci

放入[client]和[mysqldump]部分：

default-character-set=utf8

之后重启mysql

 )

 SELECT DISTINCT * FROM (

 SELECT  * FROM Childs) t
