这两天利用java爬虫爬取数据,结果在存入数据库的时候遇到了乱码问题。
是数据库默认的编码格式是latin1格式,我用的是免安装版本的,下面就说一下怎么修改。
在你解压的mysql文件夹下,复制一份my-default.ini文件 (一定要复制一份),命名为myini,并在里面添加下面句子:
红色部分是我加进去的,这样就可以了。重启数据库,然后进入dos命令进入数据库
使用命令show variable like 'char%';
就可以了

# Remove leading # and set to the amount of RAM for the most important data

# innodb_buffer_pool_size = 128M
# Remove leading # to turn on a very important data integrity option: logging

# log_bin
# These are commonly set, remove the # and set as required.

# Remove leading # to set options mainly useful for reporting servers.
# The server defaults are faster for transactions and fast SELECTs.
# Adjust sizes as needed, experiment to find the optimal values.

# sort_buffer_size = 2M
# read_rnd_buffer_size = 2M
