1、首先先回忆自身项目的编码格式，即在本地进行编码时使用的编码格式。UTF-82、检测tomcat的设置问题，在web.xml和server中的设置：server.xml中：

URIEncoding="UTF-8" />

web.xml中以下内容去掉注释：

setCharacterEncodingFilter

org.apache.catalina.filters.SetCharacterEncodingFilter

encoding

UTF-8

true

3、检测ubuntu服务器中的编码格式

//检测本地语言环境：

locale

//进行配置的修改

vi /etc/profile

//添加下列行(LC_ALL表示全部设置，但不影响LANG)：

export LANG="en_US.UTF-8"

export LC_ALL="zh_CN.UTF-8"

//设置后使其起效

source /etc/profile

//当出现 cannot 错误时 ,使用以下命令进行安装相应语言包

sudo locale-gen zn_CN.UTF-8

//当起效后，要再次进入配置中修改，将刚添加的两行删除，不然会影响jdk环境

4、mysql的配置1.修改mysql默认配置：默认的mysql配置：server、client都是latin1,对中文是不支持的，这里改为utf8方法：修改配置文件：

vim /etc/mysql/my.cnf

[mysqld]character-set-server=utf8collation-server=utf8_general_ci

重启mysql

/etc/init.d/mysql restart

检查编码方式：

mysql> show variables like 'char%';+--------------------------+----------------------------+| Variable_name | Value |+--------------------------+----------------------------+| character_set_client | utf8 || character_set_connection | utf8 || character_set_database | latin1 || character_set_filesystem | binary || character_set_results | utf8 || character_set_server | utf8 || character_set_system | utf8 || character_sets_dir | /usr/share/mysql/charsets/ |+--------------------------+----------------------------+2.修改项目使用的数据库的配置修改此数据库的编码方式为utf8(默认是latin1)mysql> alter database 数据库名 character set utf8;

查看此数据库的编码：mysql> status

Connection id: 41Current database: tslcrmsCurrent user: root@localhostSSL: Not in useCurrent pager: stdoutUsing outfile: ''Using delimiter: ;Server version: 5.5.38-0ubuntu0.14.04.1 (Ubuntu)Protocol version: 10Connection: Localhost via UNIX socketServer characterset: utf8Db characterset: utf8Client characterset: utf8Conn. characterset: utf8UNIX socket: /var/run/mysqld/mysqld.sockUptime: 53 min 14 sec

mysql> show create database tslcrms;+----------+------------------------------------------------------------------+| Database | Create Database |+----------+------------------------------------------------------------------+| tslcrms | CREATE DATABASE 数据库名 /*!40100 DEFAULT CHARACTER SET utf8 */ |+----------+------------------------------------------------------------------+

3.导入数据库文件中的表、字段的编码方式都修改成utf8可以直接改.sql文件，改完导入。也可以先导入，再用命令查看和更改。

附：在mysql中使用命令修改字符集：mysql> SET character_set_client = utf8 ;

mysql> SET character_set_connection = utf8 ;

mysql> SET character_set_database = utf8 ;

mysql> SET character_set_results = utf8 ;

mysql> SET character_set_server = utf8 ;

mysql> SET collation_connection = utf8 ;

mysql> SET collation_database = utf8 ;

mysql> SET collation_server = utf8 ;

SET NAMES 'utf8';相当于下面的三句指令：SET character_set_client = utf8;SET character_set_results = utf8;SET character_set_connection = utf8;

5、另外mysql默认的字符集为latin1的，所以要改为utf8的。很多网上的文章执行“sudo vi /etc/mysql/my.cnf”，可是打开一看，里面就两行话：

!includedir /etc/mysql/conf.d/

!includedir /etc/mysql/mysql.conf.d/

想来mysql的配置文件应该是在那两个文件夹下面，于是尝试之下打开了/etc/mysql/mysql.conf.d/ 下的mysqld.cnf文件，执行下面的命令：

~$ sudo vi /etc/mysql/mysql.conf.d/mysqld.cnf

[client]default-character-set=utf8

[mysqld_safe]socket = /var/run/mysqld/mysqld.socknice = 0

[mysqld]character-set-server=utf8collation-server=utf8_general_ci

后重启Mysql服务器~$ sudo /etc/init.d/mysql restart~$ mysql -u root -pmysql> show variables like "%char%"+--------------------------+----------------------------+| Variable_name | Value |+--------------------------+----------------------------+| 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 || character_sets_dir | /usr/share/mysql/charsets/ |+--------------------------+----------------------------+
