play framework mysql统一utf8

表单提交中文字段，使用默认设置，乱码。

全部统一为utf8。服务器为centos，只做演示，没考虑其他平台浏览器编码。

1.将mysql相关配置全改为utf8。 vim /etc/my.cnf

[mysqld]
datadir=/var/lib/mysql
#datadir=/home/mysql
socket=/var/lib/mysql/mysql.sock
#socket=/home/mysql/mysql.sock
user=mysql
# Disabling symbolic-links is recommended to prevent assorted security risks
symbolic-links=0

[mysqld_safe]
#log-error=/var/log/mysqld.log
log-error=/var/log/mysqld.log
#pid-file=/var/run/mysqld/mysqld.pid
pid-file=/var/run/mysqld/mysqld.pid

#add by user
default-character-set=utf8

[mysqld]
init_connect=’SET NAMES utf8’
default-character-set=utf8

[mysql]
default-character-set=utf8

2.创建数据库 utf8

REATE DATABASE `databasename` CHARACTER SET 'utf8' COLLATE 'utf8_general_ci';

3.创建表也utf8

CREATE TABLE IF NOT EXISTS suploadfileinfo (
id INT auto_increment primary key not null,
filename VARCHAR(255),
filesize    VARCHAR(255),
time TIMESTAMP DEFAULT now()
)
ENGINE=InnoDB   DEFAULT   CHARSET=utf8;

4. play framework连接mysql时也utf8. conf/application.conf

db.default.driver= com.mysql.jdbc.Driver
db.default.url="jdbc:mysql://localhost/machinelearning?useUnicode=true&characterEncoding=UTF-8"
db.default.username=root
db.default.password=""
